Safety BeltsThis section of the manualdescribes how to use safety beltsproperly. It also describes somethings not to do with safety belts.

{ WARNING

Do not let anyone ride where asafety belt cannot be wornproperly. In a crash, if you or yourpassenger(s) are not wearingsafety belts, injuries can be muchworse than if you are wearingsafety belts. You can be seriouslyinjured or killed by hitting thingsinside the vehicle harder or bybeing ejected from the vehicle. Inaddition, anyone who is notbuckled up can strike otherpassengers in the vehicle.

(Continued)

WARNING (Continued)

It is extremely dangerous to ridein a cargo area, inside or outsideof a vehicle. In a collision,passengers riding in these areasare more likely to be seriouslyinjured or killed. Do not allowpassengers to ride in any area ofthe vehicle that is not equippedwith seats and safety belts.

Always wear a safety belt, andcheck that all passenger(s) arerestrained properly too.

This vehicle has indicators as areminder to buckle the safety belts.See Safety Belt Reminders onpage 5‑19.

Why Safety Belts Work

When riding in a vehicle, you travelas fast as the vehicle does. If thevehicle stops suddenly, you keepgoing until something stops you.It could be the windshield, theinstrument panel, or the safety belts!

Seats and Restraints 3-15

When you wear a safety belt, youand the vehicle slow down together.There is more time to stop becauseyou stop over a longer distance and,when worn properly, your strongestbones take the forces from thesafety belts. That is why wearingsafety belts makes such goodsense.

Questions and Answers AboutSafety Belts

Q: Will I be trapped in the vehicleafter a crash if I am wearing asafety belt?

A: You could be— whether you arewearing a safety belt or not.Your chance of being consciousduring and after a crash, so youcan unbuckle and get out, ismuch greater if you are belted.

Q: If my vehicle has airbags, whyshould I have to wear safetybelts?

A: Airbags are supplementalsystems only; so they work withsafety belts— not instead ofthem. Whether or not an airbagis provided, all occupants stillhave to buckle up to get themost protection.

Also, in nearly all states and inall Canadian provinces, the lawrequires wearing safety belts.

How to Wear Safety BeltsProperlyThis section is only for people ofadult size.

There are special things to knowabout safety belts and children. Andthere are different rules for smallerchildren and infants. If a child will beriding in the vehicle, see OlderChildren on page 3‑45 or Infantsand Young Children on page 3‑48.Follow those rules for everyone'sprotection.

It is very important for all occupantsto buckle up. Statistics show thatunbelted people are hurt more oftenin crashes than those who arewearing safety belts.

There are important things to knowabout wearing a safety belt properly.

. Sit up straight and always keepyour feet on the floor in frontof you.

. Always use the correct bucklefor your seating position.

. Wear the lap part of the belt lowand snug on the hips, justtouching the thighs. In a crash,this applies force to the strongpelvic bones and you would beless likely to slide under the lapbelt. If you slid under it, the beltwould apply force on yourabdomen. This could causeserious or even fatal injuries.

. Wear the shoulder belt over theshoulder and across the chest.These parts of the body are bestable to take belt restrainingforces. The shoulder belt locks ifthere is a sudden stop or crash.

{ WARNING

You can be seriously injured,or even killed, by not wearingyour safety belt properly.

. Never allow the lap orshoulder belt to becomeloose or twisted.

. Never wear the shoulder beltunder both arms or behindyour back.

. Never route the lap orshoulder belt over anarmrest.

Safety Belt Pretensioners

This vehicle has safety beltpretensioners for front outboardoccupants. Although the safety beltpretensioners cannot be seen, theyare part of the safety belt assembly.They can help tighten the safetybelts during the early stages of amoderate to severe frontal, nearfrontal, or rear crash if the thresholdconditions for pretensioneractivation are met. And, if yourvehicle has side impact airbags,safety belt pretensioners can helptighten the safety belts in a sidecrash or a rollover event.

Pretensioners work only once. If thepretensioners activate in a crash,they will need to be replaced, andprobably other new parts for thevehicle's safety belt system. SeeReplacing Safety Belt System Partsafter a Crash on page 3‑24.

Rear Safety Belt ComfortGuides

This vehicle may have rear shoulderbelt comfort guides. If not, they areavailable through your dealer. Theguides may provide added safetybelt comfort for older children whohave outgrown booster seats andfor some adults. When installed andproperly adjusted, the comfort guidepositions the belt away from theneck and head.

Here is how to install a comfortguide to the shoulder belt:

1. Remove the guide from itsstorage clip on the interior body.

2. Place the guide over the beltand insert the two edges of thebelt into the slots of the guide.

Safety Belt Use DuringPregnancySafety belts work for everyone,including pregnant women. Like alloccupants, they are more likely tobe seriously injured if they do notwear safety belts.

A pregnant woman should wear alap-shoulder belt, and the lapportion should be worn as low aspossible, below the rounding,throughout the pregnancy.

The best way to protect the fetus isto protect the mother. When a safetybelt is worn properly, it is more likelythat the fetus will not be hurt in acrash. For pregnant women, as foranyone, the key to making safetybelts effective is wearing themproperly.

Lap BeltThis section is only for the lap belt.To learn how to wear a lap-shoulderbelt, see Lap-Shoulder Belt onpage 3‑17.

The vehicle may have a centerseating position with a lap safetybelt. The lap safety belt does nothave a retractor.

To make the belt longer, tilt the latchplate and pull it along the belt.

Buckle, position, and release it thesame way as the lap part of alap-shoulder belt.

If the belt is not long enough, seeSafety Belt Extender on page 3‑23.

Make sure the release button on thebuckle is positioned so you wouldbe able to unbuckle the safety beltquickly if necessary.

Safety Belt ExtenderIf the vehicle's safety belt will fastenaround you, you should use it.

But if a safety belt is not longenough, your dealer will order youan extender. When you go in toorder it, take the heaviest coat youwill wear, so the extender will belong enough for you. To help avoidpersonal injury, do not let someoneelse use it, and use it only for theseat it is made to fit. The extenderhas been designed for adults. Neveruse it for securing child seats. Towear it, attach it to the regular safetybelt. For more information, see theinstruction sheet that comes withthe extender.

Safety System CheckNow and then, check that the safetybelt reminder light, safety belts,buckles, latch plates, retractors, andanchorages are all working properly.Look for any other loose ordamaged safety belt system partsthat might keep a safety belt systemfrom doing its job. See your dealerto have it repaired. Torn or frayedsafety belts may not protect you in acrash. They can rip apart underimpact forces. If a belt is torn orfrayed, get a new one right away.

Make sure the safety belt reminderlight is working. See Safety BeltReminders on page 5‑19.

Keep safety belts clean and dry.See Safety Belt Care on page 3‑24.

Here are the most important thingsto know about the airbag system:

{ WARNING

You can be severely injured orkilled in a crash if you are notwearing your safety belt— even ifyou have airbags. Airbags aredesigned to work with safetybelts, but do not replace them.Also, airbags are not designed todeploy in every crash. In somecrashes safety belts are your onlyrestraint. See When Should anAirbag Inflate? on page 3‑29.

Wearing your safety belt during acrash helps reduce your chanceof hitting things inside the vehicleor being ejected from it. Airbagsare “supplemental restraints” tothe safety belts. Everyone in yourvehicle should wear a safety beltproperly—whether or not there isan airbag for that person.

{ WARNING

Because airbags inflate with greatforce and faster than the blink ofan eye, anyone who is upagainst, or very close to anyairbag when it inflates can beseriously injured or killed. Do notsit unnecessarily close to anyairbag, as you would be if sittingon the edge of the seat or leaningforward. Safety belts help keepyou in position before and duringa crash. Always wear a safetybelt, even with airbags. The drivershould sit as far back as possiblewhile still maintaining control ofthe vehicle.

Occupants should not lean on orsleep against the door or sidewindows in seating positions withseat-mounted side impact airbagsand/or roof-rail airbags.

{ WARNING

Children who are up against,or very close to, any airbag whenit inflates can be seriouslyinjured or killed. Airbags pluslap-shoulder belts offer protectionfor adults and older children, butnot for young children and infants.Neither the vehicle safety beltsystem nor its airbag system isdesigned for them. Youngchildren and infants need theprotection that a child restraintsystem can provide. Alwayssecure children properly in thevehicle. To read how, see OlderChildren on page 3‑45 or Infantsand Young Children onpage 3‑48.

When Should an AirbagInflate?Frontal airbags are designed toinflate in moderate to severe frontalor near-frontal crashes to helpreduce the potential for severeinjuries mainly to the driver's or rightfront passenger's head and chest.However, they are only designed toinflate if the impact exceeds apredetermined deploymentthreshold. Deployment thresholdsare used to predict how severe acrash is likely to be in time for theairbags to inflate and help restrainthe occupants.

Whether the frontal airbags will orshould deploy is not based on howfast your vehicle is traveling.It depends largely on what you hit,the direction of the impact, and howquickly your vehicle slows down.

Frontal airbags may inflate atdifferent crash speeds. Forexample:. If the vehicle hits a stationary

object, the airbags could inflateat a different crash speed than ifthe vehicle hits a moving object.

. If the vehicle hits an object thatdeforms, the airbags couldinflate at a different crash speedthan if the vehicle hits an objectthat does not deform.

. If the vehicle hits a narrow object(like a pole), the airbags couldinflate at a different crash speedthan if the vehicle hits a wideobject (like a wall).

. If the vehicle goes into an objectat an angle, the airbags couldinflate at a different crash speedthan if the vehicle goes straightinto the object.

Thresholds can also vary withspecific vehicle design.

Frontal airbags are not intended toinflate during vehicle rollovers, rearimpacts, or in many side impacts.

If the GVWR (Gross Vehicle WeightRating) of your vehicle is 3 855 kg(8,500 lb) or above, the vehicle hassingle stage airbags. If the GVWR isbelow 3 855 kg (8,500 lb) then thevehicle has dual stage airbags.Vehicles with a full bench seat areequipped with single state airbags.You can find the GVWR on thecertification label on the rear edgeof the driver door. See Vehicle LoadLimits on page 9‑17 for moreinformation.

3-30 Seats and Restraints

The vehicle may have dual‐stagefrontal airbags. Dual-stage airbagsadjust the restraint according tocrash severity. The vehicle haselectronic frontal sensors, whichhelp the sensing system distinguishbetween a moderate frontal impactand a more severe frontal impact.For moderate frontal impacts,dual-stage airbags inflate at a levelless than full deployment. For moresevere frontal impacts, fulldeployment occurs.

Vehicles with dual stage airbagsalso have seat position sensorswhich enable the sensing system tomonitor the position of the driverseat (all models), and on crew caband extended cab models the rightfront passenger seat on light dutymodels only. The seat positionsensor provides information that isused to determine if the airbagsshould deploy at a reduced level orat full deployment.

The vehicle may or may not haveseat‐mounted side impact androof-rail airbags. See Airbag Systemon page 3‑25. Seat‐mounted sideimpact and roof-rail airbags areintended to inflate in moderate tosevere side crashes. In addition,these roof-rail airbags are intendedto inflate during a rollover or in asevere frontal impact. Seat‐mountedside impact and roof-rail airbags willinflate if the crash severity is abovethe system's designed thresholdlevel. The threshold level can varywith specific vehicle design.

Roof-rail airbags are not intendedto inflate in rear impacts. Aseat‐mounted side impact airbag isintended to deploy on the side of thevehicle that is struck. Both roof-railairbags will deploy when either sideof the vehicle is struck, or if thesensing system predicts that thevehicle is about to roll over, or in asevere frontal impact.

In any particular crash, no one cansay whether an airbag should haveinflated simply because of thedamage to a vehicle or because ofwhat the repair costs were. Forfrontal airbags, inflation isdetermined by what the vehicle hits,the angle of the impact, and howquickly the vehicle slows down. Forseat‐mounted side impact androof-rail airbags, deployment isdetermined by the location andseverity of the side impact. In arollover event, roof-rail airbagdeployment is determined by thedirection of the roll.

Seats and Restraints 3-31

What Makes an AirbagInflate?In a deployment event, the sensingsystem sends an electrical signaltriggering a release of gas from theinflator. Gas from the inflator fills theairbag causing the bag to break outof the cover and deploy. The inflator,the airbag, and related hardware areall part of the airbag module.

Frontal airbag modules are locatedinside the steering wheel andinstrument panel. For vehicles withseat‐mounted side impact airbags,there are airbags modules in theside of the front seatbacks closestto the door. For vehicles withroof-rail airbags, there are airbagmodules in the ceiling of the vehicle,near the side windows that haveoccupant seating positions.

How Does an AirbagRestrain?In moderate to severe frontal ornear frontal collisions, even beltedoccupants can contact the steeringwheel or the instrument panel. Inmoderate to severe side collisions,even belted occupants can contactthe inside of the vehicle.

Airbags supplement the protectionprovided by safety belts. Frontalairbags distribute the force of theimpact more evenly over theoccupant's upper body, stoppingthe occupant more gradually.Seat‐mounted side impact androof-rail airbags distribute the forceof the impact more evenly over theoccupant's upper body.

Rollover capable roof-rail airbagsare designed to help contain thehead and chest of occupants in theoutboard seating positions in thefirst and second rows. The rollovercapable roof-rail airbags aredesigned to help reduce the risk offull or partial ejection in rolloverevents, although no system canprevent all such ejections.

But airbags would not help in manytypes of collisions, primarilybecause the occupant's motion isnot toward those airbags. See WhenShould an Airbag Inflate? onpage 3‑29 for more information.

Airbags should never be regardedas anything more than a supplementto safety belts.

What Will You See afteran Airbag Inflates?After the frontal airbags andseat-mounted side impact airbagsinflate, they quickly deflate, soquickly that some people may noteven realize an airbag inflated.Roof-rail airbags may still be at leastpartially inflated for some time afterthey deploy. Some components ofthe airbag module may be hot forseveral minutes. For location of theairbag modules, see What Makesan Airbag Inflate? on page 3‑31.

The parts of the airbag that comeinto contact with you may be warm,but not too hot to touch. There maybe some smoke and dust comingfrom the vents in the deflatedairbags. Airbag inflation does notprevent the driver from seeing out ofthe windshield or being able to steerthe vehicle, nor does it preventpeople from leaving the vehicle.

{ WARNING

When an airbag inflates, theremay be dust in the air. This dustcould cause breathing problemsfor people with a history ofasthma or other breathing trouble.To avoid this, everyone in thevehicle should get out as soon asit is safe to do so. If you havebreathing problems but cannotget out of the vehicle after anairbag inflates, then get fresh airby opening a window or a door.If you experience breathingproblems following an airbagdeployment, you should seekmedical attention.

The vehicle may have a feature thatmay automatically unlock the doors,turn on the interior lamps andhazard warning flashers, and shutoff the fuel system after the airbagsinflate. You can lock the doors, turn

off the interior lamps and hazardwarning flashers by using thecontrols for those features.

{ WARNING

A crash severe enough to inflatethe airbags may have alsodamaged important functions inthe vehicle, such as the fuelsystem, brake and steeringsystems, etc. Even if the vehicleappears to be drivable after amoderate crash, there may beconcealed damage that couldmake it difficult to safely operatethe vehicle.

Use caution if you should attemptto restart the engine after a crashhas occurred.

In many crashes severe enough toinflate the airbag, windshields arebroken by vehicle deformation.Additional windshield breakage mayalso occur from the right frontpassenger airbag.. Airbags are designed to inflate

only once. After an airbaginflates, you will need some newparts for the airbag system.If you do not get them, theairbag system will not be thereto help protect you in anothercrash. A new system will includeairbag modules and possiblyother parts. The service manualfor your vehicle covers the needto replace other parts.

. The vehicle has a crash sensingand diagnostic module whichrecords information after acrash. See Vehicle DataRecording and Privacy onpage 13‑21 and Event DataRecorders on page 13‑22.

. Let only qualified technicianswork on the airbag systems.Improper service can mean thatan airbag system will not workproperly. See your dealer forservice.

The passenger sensing system willturn off the right front passengerfrontal airbag under certainconditions. The driver airbag,seat‐mounted side impact airbags(if equipped), and the roof-railairbags (if equipped) are notaffected by the passenger sensingsystem.

The passenger sensing systemworks with sensors that are part ofthe right front passenger seat andsafety belt. The sensors aredesigned to detect the presence ofa properly-seated occupant anddetermine if the right frontpassenger frontal airbag should beenabled (may inflate) or not.

According to accident statistics,children are safer when properlysecured in a rear seat in the correctchild restraint for their weightand size.

We recommend that children besecured in a rear seat, including: aninfant or a child riding in arear-facing child restraint; a childriding in a forward-facing child seat;an older child riding in a boosterseat; and children, who are largeenough, using safety belts.

A label on the sun visor says,“Never put a rear-facing child seat inthe front.” This is because the risk tothe rear-facing child is so great,if the airbag deploys.

{ WARNING

A child in a rear-facing childrestraint can be seriously injuredor killed if the right frontpassenger airbag inflates. This isbecause the back of therear-facing child restraint wouldbe very close to the inflatingairbag. A child in a forward-facingchild restraint can be seriouslyinjured or killed if the right front

WARNING (Continued)

passenger airbag inflates and thepassenger seat is in a forwardposition.

Even if the passenger sensingsystem has turned off the rightfront passenger frontal airbag, nosystem is fail-safe. No one canguarantee that an airbag will notdeploy under some unusualcircumstance, even though theairbag is turned off.

Secure rear-facing childrestraints in a rear seat, even ifthe airbag is off. If you secure aforward-facing child restraint inthe right front seat, always movethe front passenger seat as farback as it will go. It is better tosecure the child restraint in arear seat.

If the vehicle does not have a rearseat that will accommodate arear-facing child restraint, arear-facing child restraint should notbe installed in the vehicle, even ifthe airbag is off.

The passenger sensing system isdesigned to turn off the right frontpassenger frontal airbag if:. The right front passenger seat is

unoccupied.. The system determines an infant

is present in a child restraint.. A right front passenger takes

his/her weight off of the seat fora period of time.

. Or, if there is a critical problemwith the airbag system or thepassenger sensing system.

When the passenger sensingsystem has turned off the right frontpassenger frontal airbag, the offindicator will light and stay lit toremind you that the airbag is off.See Passenger Airbag StatusIndicator on page 5‑23.

The passenger sensing system isdesigned to turn on (may inflate) theright front passenger frontal airbaganytime the system senses that aperson of adult size is sittingproperly in the right frontpassenger seat.

When the passenger sensingsystem has allowed the airbag to beenabled, the on indicator will lightand stay lit to remind you that theairbag is active.

For some children, includingchildren in child restraints, and forvery small adults, the passengersensing system may or may not turnoff the right front passenger frontalairbag, depending upon theperson's seating posture and bodybuild. Everyone in your vehiclewho has outgrown child restraintsshould wear a safety beltproperly—whether or not there isan airbag for that person.

{ WARNING

If the airbag readiness light evercomes on and stays on, it meansthat something may be wrongwith the airbag system. To helpavoid injury to yourself or others,have the vehicle serviced rightaway. See Airbag ReadinessLight on page 5‑20 for moreinformation, including importantsafety information.

3-40 Seats and Restraints

If the On Indicator is Lit for aChild Restraint

If a child restraint has been installedand the on indicator is lit:

1. Turn the vehicle off.

2. Remove the child restraint fromthe vehicle.

3. Remove any additional itemsfrom the seat such as blankets,cushions, seat covers, seatheaters, or seat massagers.

4. Reinstall the child restraintfollowing the directions providedby the child restraintmanufacturer and refer toSecuring Child Restraints(Center Front Seat Position) onpage 3‑65 or Securing ChildRestraints (Right Front SeatPosition) on page 3‑65 orSecuring Child Restraints (RearSeat Position) on page 3‑63.

5. If, after reinstalling the childrestraint and restarting thevehicle, the on indicator is still lit,turn the vehicle off. Then slightlyrecline the vehicle seatback andadjust the seat cushion,if adjustable, to make sure thatthe vehicle seatback is notpushing the child restraint intothe seat cushion.

Also make sure the childrestraint is not trapped under thevehicle head restraint. If thishappens, adjust the headrestraint. See Head Restraintson page 3‑2.

6. Restart the vehicle.

The passenger sensing systemmay or may not turn off theairbag for a child in a childrestraint depending upon thechild’s seating posture and bodybuild. It is better to secure thechild restraint in a rear seat.

Seats and Restraints 3-41

If the Off Indicator is Lit for anAdult-Size Occupant

If a person of adult-size is sitting inthe right front passenger seat, butthe off indicator is lit, it could bebecause that person is not sittingproperly in the seat. If this happens,

use the following steps to allow thesystem to detect that person andenable the right front passengerfrontal airbag:

1. Turn the vehicle off.

2. Remove any additional materialfrom the seat, such as blankets,cushions, seat covers, seatheaters, or seat massagers.

3. Place the seatback in the fullyupright position.

4. Have the person sit upright inthe seat, centered on the seatcushion, with legs comfortablyextended.

5. Restart the vehicle and have theperson remain in this position fortwo to three minutes after the onindicator is lit.

Additional Factors AffectingSystem Operation

Safety belts help keep thepassenger in position on the seatduring vehicle maneuvers andbraking, which helps the passengersensing system maintain thepassenger airbag status. See“Safety Belts” and “Child Restraints”in the Index for additionalinformation about the importance ofproper restraint use.

If the shoulder portion of the belt ispulled out all the way, the childrestraint locking feature will beengaged. This may unintentionallycause the passenger sensingsystem to turn the airbag off forsome adult size occupants. If thishappens, let the belt go back all theway and start again.

3-46 Seats and Restraints

The manufacturer's instructions thatcome with the booster seat state theweight and height limitations for thatbooster. Use a booster seat with alap-shoulder belt until the childpasses the fit test below:. Sit all the way back on the seat.

Do the knees bend at the seatedge? If yes, continue. If no,return to the booster seat.

. Buckle the lap-shoulder belt.Does the shoulder belt rest onthe shoulder? If yes, continue.If no, try using the rear safetybelt comfort guide. See “RearSafety Belt Comfort Guides”under Lap-Shoulder Belt onpage 3‑17 for more information.If the shoulder belt still does notrest on the shoulder, then returnto the booster seat.

. Does the lap belt fit low andsnug on the hips, touching thethighs? If yes, continue. If no,return to the booster seat.

. Can proper safety belt fit bemaintained for the length of thetrip? If yes, continue. If no,return to the booster seat.

Q: What is the proper way towear safety belts?

A: An older child should wear alap-shoulder belt and get theadditional restraint a shoulderbelt can provide. The shoulderbelt should not cross the face orneck. The lap belt should fitsnugly below the hips, justtouching the top of the thighs.This applies belt force to thechild's pelvic bones in a crash.It should never be worn over theabdomen, which could causesevere or even fatal internalinjuries in a crash.

Also see “Rear Safety Belt ComfortGuides” under Lap-Shoulder Belt onpage 3‑17.

According to accident statistics,children and infants are safer whenproperly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition.

In a crash, children who are notbuckled up can strike other peoplewho are buckled up, or can bethrown out of the vehicle. Olderchildren need to use safety beltsproperly.

Infants and YoungChildrenEveryone in a vehicle needsprotection! This includes infants andall other children. Neither thedistance traveled nor the age andsize of the traveler changes theneed, for everyone, to use safetyrestraints. In fact, the law in everystate in the United States and inevery Canadian province sayschildren up to some age must berestrained while in a vehicle.

{ WARNING

Children can be seriously injuredor strangled if a shoulder belt iswrapped around their neck andthe safety belt continues totighten. Never leave childrenunattended in a vehicle and neverallow children to play with thesafety belts.

Airbags plus lap‐shoulder belts offerprotection for adults and olderchildren, but not for young childrenand infants. Neither the vehicle'ssafety belt system nor its airbagsystem is designed for them. Everytime infants and young children ridein vehicles, they should have theprotection provided by appropriatechild restraints.

Children who are not restrainedproperly can strike other people,or can be thrown out of the vehicle.

{ WARNING

Never hold an infant or a childwhile riding in a vehicle. Due tocrash forces, an infant or a childwill become so heavy it is notpossible to hold it during a crash.For example, in a crash at only40 km/h (25 mph), a 5.5 kg (12 lb)infant will suddenly become a110 kg (240 lb) force on a person's

3-50 Seats and Restraints

The restraint manufacturer'sinstructions that come with therestraint state the weight andheight limitations for a particularchild restraint. In addition, thereare many kinds of restraintsavailable for children withspecial needs.

{ WARNING

To reduce the risk of neck andhead injury during a crash, infantsneed complete support. In acrash, if an infant is in arear-facing child restraint, thecrash forces can be distributedacross the strongest part of aninfant's body, the back andshoulders. Infants should alwaysbe secured in rear-facing childrestraints.

{ WARNING

A young child's hip bones are stillso small that the vehicle's regularsafety belt may not remain low onthe hip bones, as it should.Instead, it may settle up aroundthe child's abdomen. In a crash,the belt would apply force on abody area that is unprotected byany bony structure. This alonecould cause serious or fatalinjuries. To reduce the risk ofserious or fatal injuries during acrash, young children shouldalways be secured in appropriatechild restraints.

When securing an add-on childrestraint, refer to the instructionsthat come with the restraint whichmay be on the restraint itself or in abooklet, or both, and to this manual.The child restraint instructions areimportant, so if they are notavailable, obtain a replacementcopy from the manufacturer.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inthe vehicle— even when no child isin it.

In some areas of the United Statesand Canada, Certified ChildPassenger Safety Technicians(CPSTs) are available to inspectand demonstrate how to correctlyuse and install child restraints. Inthe U.S., refer to the NationalHighway Traffic SafetyAdministration (NHTSA) website tolocate the nearest child safety seatinspection station. For CPSTavailability in Canada, check withTransport Canada or the ProvincialMinistry of Transportation office.

Securing the Child Within theChild Restraint

{ WARNING

A child can be seriously injured orkilled in a crash if the child is notproperly secured in the childrestraint. Secure the childproperly following the instructionsthat came with that child restraint.

Where to Put theRestraintAccording to accident statistics,children and infants are safer whenproperly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition.

We recommend that children andchild restraints be secured in a rearseat, including: an infant or a childriding in a rear-facing child restraint;a child riding in a forward-facingchild seat; an older child riding in abooster seat; and children, who arelarge enough, using safety belts.

If a child restraint is secured in theright front passenger seat, and thevehicle has a switch in the glovebox to manually turn off the rightfront passenger airbag, see AirbagOn-Off Switch on page 3‑33 andSecuring Child Restraints (CenterFront Seat Position) on page 3‑65or Securing Child Restraints (RightFront Seat Position) on page 3‑65or Securing Child Restraints (Rear

A label on the sun visor says,“Never put a rear-facing child seat inthe front.” This is because the risk tothe rear-facing child is so great,if the airbag deploys.

{ WARNING

A child in a rear-facingchild restraint can be seriouslyinjured or killed if the right frontpassenger airbag inflates.This is because the back of therear-facing child restraint wouldbe very close to the inflatingairbag. A child in a forward-facingchild restraint can be seriouslyinjured or killed if the right frontpassenger airbag inflates and thepassenger seat is in a forwardposition.

(Continued)

WARNING (Continued)

Even if the passenger sensingsystem or airbag switch hasturned off the right frontpassenger frontal airbag, nosystem is fail-safe. No one canguarantee that an airbag will notdeploy under some unusualcircumstance, even though it isturned off.

Secure rear-facing childrestraints in a rear seat, even ifthe airbag is off. If you secure aforward-facing child restraint inthe right front seat, always movethe front passenger seat as farback as it will go. It is better tosecure the child restraint in arear seat.

{ WARNING

A child in a child restraint in thecenter front seat can be badlyinjured or killed by the frontalairbags if they inflate. Neversecure a child restraint in thecenter front seat. It is alwaysbetter to secure a child restraint ina rear seat.

Do not use child restraints in thecenter front seat position.

When securing a child restraint in arear seating position, study theinstructions that came with yourchild restraint to make sure it iscompatible with this vehicle.

Child restraints and booster seatsvary considerably in size, and somemay fit in certain seating positionsbetter than others. Always makesure the child restraint is properlysecured.

Depending on where you place thechild restraint and the size of thechild restraint, you may not be ableto access adjacent safety beltassemblies or LATCH anchors foradditional passengers or childrestraints. Adjacent seatingpositions should not be used if thechild restraint prevents access to orinterferes with the routing of thesafety belt.

If the vehicle does not have a rearseat that will accommodate arear-facing child restraint, arear-facing child restraint should notbe installed in the vehicle, even ifthe airbag is off.

Wherever a child restraint isinstalled, be sure to secure thechild restraint properly.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inyour vehicle— even when no childis in it.

Lower Anchors andTethers for Children(LATCH System)The LATCH system holds a childrestraint during driving or in a crash.This system is designed to makeinstallation of a child restraint easier.The LATCH system uses anchors inthe vehicle and attachments on thechild restraint that are made for usewith the LATCH system.

Make sure that a LATCH-compatiblechild restraint is properly installedusing the anchors, or use thevehicle's safety belts to secure therestraint, following the instructionsthat came with that restraint, andalso the instructions in this manual.

When installing a child restraint witha top tether, you must also useeither the lower anchors or thesafety belts to properly secure thechild restraint. A child restraint mustnever be installed using only the toptether and anchor.

In order to use the LATCH system inyour vehicle, you need a childrestraint that has LATCHattachments. The child restraintmanufacturer will provide you withinstructions on how to use the childrestraint and its attachments. Thefollowing explains how to attach achild restraint with theseattachments in your vehicle.

Not all vehicle seating positions orchild restraints have lower anchorsand attachments or top tetheranchors and attachments.

Lower Anchors

Lower anchors (A) are metal barsbuilt into the vehicle. There are twolower anchors for each LATCHseating position that willaccommodate a child restraintwith lower attachments (B).

Top Tether Anchor

A top tether (A, C) anchors the topof the child restraint to the vehicle.A top tether anchor is builtinto the vehicle. The top tetherattachment (B) on the child restraintconnects to the top tether anchor inthe vehicle in order to reduce theforward movement and rotation ofthe child restraint during driving or ina crash.

Your child restraint may have asingle tether (A) or a dual tether (C).Either will have a singleattachment (B) to secure the toptether to the anchor.

Some child restraints that have atop tether are designed for use withor without the top tether beingattached. Others require the toptether always to be attached. InCanada, the law requires thatforward-facing child restraints havea top tether, and that the tether beattached. Be sure to read and followthe instructions for your childrestraint.

If you turned the airbag off with theswitch, turn on the right frontpassenger airbag when you removethe child restraint from the vehicleunless the person who will be sittingthere is a member of a passengerairbag risk group. See AirbagOn-Off Switch on page 3‑33 formore information, includingimportant safety information.

Heavy Duty Crew Cab Only

This vehicle has airbags. A rearseat is a safer place to secure aforward-facing child restraint. SeeWhere to Put the Restraint onpage 3‑52.

A label on the sun visor says,“Never put a rear-facing child seat inthe front.” This is because the risk tothe rear-facing child is so great,if the airbag deploys.

Never put a rear-facing childrestraint in the right front passengerseat. Here is why:

{ WARNING

A child in a rear-facing childrestraint can be seriously injuredor killed if the right frontpassenger's airbag inflates. Thisis because the back of therear-facing child restraint wouldbe very close to the inflatingairbag. Always secure arear-facing child restraint in arear seat.

If the vehicle does not have a rearseat that will accommodate arear-facing child restraint, arear-facing child restraint should notbe installed in the vehicle, even ifthe airbag is off.

If the child restraint has the LATCHsystem, see Lower Anchors andTethers for Children (LATCHSystem) on page 3‑54 for how andwhere to install the child restraintusing LATCH. If you secure a childrestraint using a safety belt and ituses a top tether, see LowerAnchors and Tethers for Children(LATCH System) on page 3‑54 fortop tether anchor locations.

Do not secure a child seat in aposition without a top tether anchorif a national or local law requiresthat the top tether be anchored, or ifthe instructions that come with thechild restraint say that the top strapmust be anchored.

In Canada, the law requires thatforward-facing child restraints havea top tether, and that the tether beattached.

Only calibrate thecompass in a magnetically cleanand safe location, such as an openparking lot, where driving thevehicle in circles is not a danger.It is suggested to calibrate awayfrom tall buildings, utility wires,manhole covers, or other industrialstructures, if possible.

If CAL should ever appear in theDIC display, the compass should becalibrated.

If the DIC display does not show aheading, for example, N for North,or the heading does not changeafter making turns, there may be astrong magnetic field interfering withthe compass. Such interferencemay be caused by a magneticCB or cell phone antenna mount, amagnetic emergency light, magneticnote pad holder, or any othermagnetic item. Turn off the vehicle,move the magnetic item, then turnon the vehicle and calibrate thecompass.

MalfunctionIndicator LampA computer system called OBD II(On-Board Diagnostics-SecondGeneration) monitors the operationof the vehicle to ensure emissionsare at acceptable levels, to producea cleaner environment. This lightcomes on when the vehicle isplaced in ON/RUN, as a check toshow it is working. If it does not,have the vehicle serviced by yourdealer. See Ignition Positions onpage 9‑28.

If the malfunction indicator lampcomes on and stays on while theengine is running, this indicates thatthere is an OBD II problem andservice is required.

Malfunctions often are indicated bythe system before any problem isapparent. Being aware of the lightcan prevent more serious damageto the vehicle. This system assiststhe service technician in correctlydiagnosing any malfunction.

Notice: If the vehicle iscontinually driven with this lighton, the emission controls mightnot work as well, the vehicle fueleconomy might not be as good,and the engine might not run assmoothly. This could lead tocostly repairs that might not becovered by the vehicle warranty.

Notice: Modifications made to theengine, transmission, exhaust,intake, or fuel system of thevehicle or the replacement of theoriginal tires with other thanthose of the same TirePerformance Criteria (TPC) canaffect the vehicle's emissioncontrols and can cause this lightto come on. Modifications tothese systems could lead tocostly repairs not covered by thevehicle warranty. This could alsoresult in a failure to pass arequired Emission Inspection/Maintenance test. SeeAccessories and Modifications onpage 10‑4.

This light comes on during amalfunction in one of two ways:

Light Flashing: A misfire conditionhas been detected. A misfireincreases vehicle emissions andcould damage the emission controlsystem on the vehicle. Diagnosisand service might be required.

To prevent more serious damage tothe vehicle:. Reduce vehicle speed.. Avoid hard accelerations.. Avoid steep uphill grades.. If towing a trailer, reduce the

amount of cargo being hauled assoon as it is possible.

If the light continues to flash, stopand park the vehicle. Turn thevehicle off, wait at least 10 seconds,and restart the engine. If the light isstill flashing, follow the previoussteps and see your dealer forservice as soon as possible.

Light On Steady: An emissioncontrol system malfunction hasbeen detected on the vehicle.Diagnosis and service might berequired.

The following may correct anemission system malfunction:. Check that the fuel cap is fully

installed. See Filling the Tank onpage 9‑84. The diagnosticsystem can determine if the fuelcap has been left off orimproperly installed. A loose ormissing fuel cap allows fuel toevaporate into the atmosphere.A few driving trips with the capproperly installed should turn thelight off.

. Check that good quality fuel isused. Poor fuel quality causesthe engine not to run asefficiently as designed and maycause stalling after start-up,stalling when the vehicle ischanged into gear, misfiring,hesitation on acceleration,or stumbling on acceleration.These conditions might go awayonce the engine is warmed up.

If one or more of these conditionsoccurs, change the fuel brand used.It will require at least one full tank ofthe proper fuel to turn the light off.

See Recommended Fuel onpage 9‑80.

If none of the above have made thelight turn off, your dealer can checkthe vehicle. The dealer has theproper test equipment anddiagnostic tools to fix anymechanical or electrical problemsthat might have developed.

Emissions Inspection andMaintenance Programs

Some local governments may haveprograms to inspect the on-vehicleemission control equipment. For theinspection, the emission system testequipment is connected to thevehicle’s Data LinkConnector (DLC).

The DLC is under the instrumentpanel to the left of the steeringwheel. See your dealer if assistanceis needed.

The vehicle may not passinspection if:. The malfunction indicator lamp is

on with the engine running, or ifthe light does not come on whenthe ignition is turned to ON/RUNwhile the engine is off. See yourdealer for assistance in verifyingproper operation of themalfunction indicator lamp.

. The OBD II (On-BoardDiagnostics) system determinesthat critical emission controlsystems have not beencompletely diagnosed. Thevehicle would be considered notready for inspection. This canhappen if the 12-volt battery hasrecently been replaced or rundown. The diagnostic system isdesigned to evaluate criticalemission control systems duringnormal driving. This can takeseveral days of routine driving.

If this has been done and thevehicle still does not pass theinspection for lack of OBD IIsystem readiness, your dealercan prepare the vehicle forinspection.

Exit LightingThe interior lamps come on whenthe key is removed from the ignition.They turn off automatically in20 seconds. The lights do not comeon if the dome override button ispressed in.

Battery LoadManagementThe vehicle has Electric PowerManagement (EPM) that estimatesthe battery's temperature and stateof charge. It then adjusts the voltagefor best performance and extendedlife of the battery.

When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. If the vehiclehas a voltmeter gauge or a voltagedisplay on the Driver InformationCenter (DIC), you may see thevoltage move up or down. This isnormal. If there is a problem, analert will be displayed.

The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinning fastenough at idle to produce all of thepower needed for very highelectrical loads.

A high electrical load occurs whenseveral of the following are on, suchas: headlamps, high beams, foglamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.

EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power wheneverneeded. It can temporarily reducethe power demands of someaccessories.

Normally, these actions occur insteps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to thedriver. If so, a DIC message mightbe displayed, such as BATTERYSAVER ACTIVE, BATTERYVOLTAGE LOW, or LOW BATTERY.If one of these messages displays, itis recommended that the driverreduce the electrical loads as muchas possible. See Driver InformationCenter (DIC) on page 5‑33.

If there isinterference or static, unplug theitem from the accessory poweroutlet.

AM

The range for most AM stations isgreater than for FM, especially atnight. The longer range can causestation frequencies to interfere witheach other. For better radioreception, most AM radio stationsboost the power levels during theday, and then reduce these levelsduring the night. Static can alsooccur when things like storms andpower lines interfere with radioreception. When this happens, tryreducing the treble on the radio.

FM Stereo

FM signals only reach about16 to 65 km (10 to 40 mi). Althoughthe radio has a built-in electroniccircuit that automatically works toreduce interference, some static canoccur, especially around tallbuildings or hills, causing the soundto fade in and out.

XM™ Satellite Radio Service

XM Satellite Radio Service givesdigital radio reception from coast tocoast in the 48 contiguous UnitedStates, and in Canada. Just as withFM, tall buildings or hills caninterfere with satellite radio signals,causing the sound to fade in andout. In addition, traveling or standingunder heavy foliage, bridges,garages, or tunnels may cause lossof the XM signal for a period of time.

Cellular Phone Usage

Cellular phone usage may causeinterference with the vehicle's radio.This interference may occur whenmaking or receiving phone calls,charging the phone's battery,or simply having the phone on. Thisinterference causes an increasedlevel of static while listening to theradio. If static is received whilelistening to the radio, unplug thecellular phone and turn it off.

Fixed Mast AntennaThe fixed mast antenna canwithstand most car washes withoutbeing damaged as long as it issecurely attached to the base. If themast becomes slightly bent,straighten it out by hand. If the mastis badly bent, replace it.

Occasionally check to make surethe antenna is tightened to its base.If tightening is required, tighten byhand until fully seated plusone quarter turn.

Satellite Radio AntennaThe XM Satellite Radio antenna islocated on the roof of the vehicle.Keep the antenna clear ofobstructions for clear radioreception.

If the vehicle has a sunroof, theperformance of the XM system(if equipped) may be affected if thesunroof is open.

{ WARNING

Taking your eyes off the road toolong or too often could cause acrash resulting in injury or death.Focus your attention on driving.

Refer to the infotainment section formore information on using thatsystem, including pairing and usinga cell phone.

If equipped, refer to the navigationmanual for information on thatsystem, including pairing and usinga cell phone.

Defensive DrivingDefensive driving means “alwaysexpect the unexpected.” The firststep in driving defensively is to wearthe safety belt. See Safety Belts onpage 3‑14.. Assume that other road users

(pedestrians, bicyclists, andother drivers) are going to becareless and make mistakes.Anticipate what they might doand be ready.

. Allow enough following distancebetween you and the driver infront of you.

. Focus on the task of driving.

Drunk DrivingDeath and injury associated withdrinking and driving is a globaltragedy.

{ WARNING

Drinking and then driving is verydangerous. Your reflexes,perceptions, attentiveness, andjudgment can be affected by evena small amount of alcohol. Youcan have a serious — or evenfatal — collision if you drive afterdrinking.

Do not drink and drive or ride witha driver who has been drinking.Ride home in a cab; or if you arewith a group, designate a driverwho will not drink.

Control of a VehicleBraking, steering, and acceleratingare important factors in helping tocontrol a vehicle while driving.

Black plate (4,1)Chevrolet Silverado Owner Manual - 2012

9-4 Driving and Operating

BrakingBraking action involves perceptiontime and reaction time. Deciding topush the brake pedal is perceptiontime. Actually doing it isreaction time.

Average driver reaction time isabout three-quarters of a second. Inthat time, a vehicle moving at100 km/h (60 mph) travels 20 m(66 ft), which could be a lot ofdistance in an emergency.

Helpful braking tips to keep in mindinclude:. Keep enough distance between

you and the vehicle in frontof you.

. Avoid needless heavy braking.

. Keep pace with traffic.

If the engine ever stops while thevehicle is being driven, brakenormally but do not pump thebrakes. Doing so could make thepedal harder to push down. If theengine stops, there will be some

power brake assist but it will beused when the brake is applied.Once the power assist is used up, itcan take longer to stop and thebrake pedal will be harder to push.

Steering

Hydraulic Power Steering

Your vehicle has hydraulicpower steering. It may requiremaintenance. See Power SteeringFluid Power Steering Fluid onpage 10‑28.

If power steering assist is lostbecause the engine stops or thepower steering system is notfunctioning, the vehicle can besteered but may required increasedeffort. See your dealer if there is aproblem.

If the vehicle is a hybrid, see thehybrid supplement for moreinformation.

Curve Tips. Take curves at a reasonable

speed.. Reduce speed before entering a

curve.. Maintain a reasonable steady

speed through the curve. Wait until the vehicle is out of

the curve before acceleratinggently into the straightaway.

Steering in Emergencies. There are some situations when

steering around a problem maybe more effective than braking.

. Holding both sides of thesteering wheel allows you to turn180 degrees without removinga hand.

. Antilock Brake System (ABS)allows steering while braking.

Driving and Operating 9-5

Off-Road Recovery

The vehicle's right wheels can dropoff the edge of a road onto theshoulder while driving. Followthese tips:

1. Ease off the accelerator andthen, if there is nothing in theway, steer the vehicle so that itstraddles the edge of thepavement.

2. Turn the steering wheel aboutone-eighth of a turn, until theright front tire contacts thepavement edge.

3. Then turn the steering wheel togo straight down the roadway.

Loss of Control

Skidding

There are three types of skids thatcorrespond to the vehicle's threecontrol systems:. Braking Skid — wheels are not

rolling.. Steering or Cornering

Skid — too much speed orsteering in a curve causes tiresto slip and lose cornering force.

. Acceleration Skid — too muchthrottle causes the drivingwheels to spin.

Defensive drivers avoid most skidsby taking reasonable care suited toexisting conditions, and by notoverdriving those conditions. Butskids are always possible.

If the vehicle starts to slide, followthese suggestions:. Ease your foot off the

accelerator pedal and quicklysteer the way you want thevehicle to go. The vehicle maystraighten out. Be ready for asecond skid if it occurs.

. Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues — suchas enough water, ice, or packedsnow on the road to make amirrored surface — and slowdown when you have any doubt.

9-6 Driving and Operating

. Try to avoid sudden steering,acceleration, or braking,including reducing vehicle speedby shifting to a lower gear. Anysudden changes could causethe tires to slide.

Remember: Antilock brakes helpavoid only the braking skid.

Off-Road DrivingFour-wheel-drive vehicles can beused for off-road driving. Vehicleswithout four-wheel drive andvehicles not equipped with AllTerrain (AT) or On-Off Road (OOR)tires must not be driven off-roadexcept on a level, solid surface. Tocontact the tire manufacturer formore information about the originalequipment tires, see the LimitedWarranty and Owner AssistanceInformation manual.

Controlling the vehicle is the key tosuccessful off-road driving. One ofthe best ways to control the vehicleis to control the speed.

{ WARNING

When driving off-road, bouncingand quick changes in directioncan easily throw you out ofposition. This could cause you tolose control and crash. You andyour passengers should alwayswear safety belts.

Before Driving Off-Road. Have all necessary maintenance

and service work completed.. Fuel the vehicle, fill fluid levels,

and check inflation pressure inall tires, including the spare,if equipped.

. Read all the information aboutfour-wheel-drive vehicles in thismanual.

. Make sure all underbodyshields, if equipped, are properlyattached.

. Know the local laws that apply tooff-road driving.

To gain more ground clearance ifneeded, it may be necessary toremove the front fascia lowerair dam.

Notice: Operating the vehicle forextended periods without thefront fascia lower air daminstalled can cause improper airflow to the engine. Re‐attach thefront fascia air dam after off-roaddriving.

Loading the Vehicle forOff-Road Driving

{ WARNING

. Unsecured cargo on the loadfloor can be tossed aboutwhen driving over roughterrain. You or yourpassengers can be struck byflying objects. Secure thecargo properly.

. Keep cargo in the cargo areaas far forward and as low aspossible. The heaviest thingsshould be on the floor,forward of the rear axle.

. Heavy loads on the roof raisethe vehicle's center of gravity,making it more likely to rollover. You can be seriously orfatally injured if the vehiclerolls over. Put heavy loadsinside the cargo area, not onthe roof.

For more information about loadingthe vehicle, see Vehicle Load Limitsand Tires.

Environmental Concerns. Always use established trails,

roads, and areas that have beenset aside for public off-roadrecreational driving and obey allposted regulations.

. Do not damage shrubs, flowers,trees, or grasses or disturbwildlife.

. Do not park over things thatburn. See Parking Over Thingsthat Burn.

9-8 Driving and Operating

Driving on Hills

Driving safely on hills requires goodjudgment and an understanding ofwhat the vehicle can and cannot do.

{ WARNING

If the vehicle has the two‐speedautomatic transfer case, shiftingthe transfer case to N (Neutral)can cause your vehicle to rolleven if the transmission is inP (Park) for an automatictransmission or any gear positionfor a manual transmission. This isbecause the N (Neutral) positionon the transfer case overrides thetransmission. You or someoneelse could be injured. If leavingthe vehicle, set the parking brakeand shift the transmission toP (Park) for an automatictransmission or any gear positionfor a manual transmission. Shiftthe transfer case to any positionbut N (Neutral).

Before driving on a hill, assessthe steepness, traction, andobstructions. If the terrain aheadcannot be seen, get out of thevehicle and walk the hill beforedriving further.

When driving on hills:. Use a low gear and keep a firm

grip on the steering wheel.. Maintain a slow speed.. When possible, drive straight up

or down the hill.. Slow down when approaching

the top of the hill.. Use headlamps even during the

day to make the vehicle morevisible.

{ WARNING

Driving to the top of a hill at highspeed can cause an accident.There could be a drop-off,embankment, cliff, or evenanother vehicle. You could beseriously injured or killed. As younear the top of a hill, slow downand stay alert.

. Never go downhill forward orbackward with either thetransmission or transfer case inN (Neutral). The brakes couldoverheat and you could losecontrol.

Driving and Operating 9-9

{ WARNING

If the vehicle has the two‐speedautomatic transfer case, shiftingthe transfer case to N (Neutral)can cause your vehicle to rolleven if the transmission is inP (Park). This is because theN (Neutral) position on thetransfer case overrides thetransmission. You or someoneelse could be injured. If leavingthe vehicle, set the parking brakeand shift the transmission toP (Park). Shift the transfer case toany position but N (Neutral).

. When driving down a hill, keepthe vehicle headed straightdown. Use a low gear becausethe engine will work with thebrakes to slow the vehicle andhelp keep the vehicle undercontrol.

{ WARNING

Heavy braking when going downa hill can cause your brakes tooverheat and fade. This couldcause loss of control and you orothers could be injured or killed.Apply the brakes lightly whendescending a hill and use a lowgear to keep vehicle speed undercontrol.

If the vehicle stalls on a hill:

1. Apply the brakes to stop thevehicle, and then apply theparking brake.

2. Shift into P (Park) for anautomatic transmission or1 (First) for a manualtransmission and then restart theengine.. If driving uphill when the

vehicle stalls, shift toR (Reverse), release theparking brake, and backstraight down.

. Never try to turn the vehiclearound. If the hill is steepenough to stall the vehicle,it is steep enough to causeit to roll over.

. If you cannot make it up thehill, back straight downthe hill.

. Never back down a hill inN (Neutral) using only thebrake.

. The vehicle can rollbackward quickly and youcould lose control.

. If driving downhill when thevehicle stalls, shift to alower gear, release theparking brake, and drivestraight down the hill.

9-10 Driving and Operating

3. If the vehicle cannot be restartedafter stalling, set the parkingbrake, shift an automatictransmission into P (Park) or amanual transmission into1 (First), and turn the vehicle off.

3.1. Leave the vehicle andseek help.

3.2. Stay clear of the path thevehicle would take if itrolled downhill.

. Avoid turns that take the vehicleacross the incline of the hill.A hill that can be driven straightup or down might be too steep todrive across. Driving across anincline puts more weight on thedownhill wheels which couldcause a downhill slide or arollover.

. Surface conditions can be aproblem. Loose gravel, muddyspots, or even wet grass cancause the tires to slip sideways,downhill. If the vehicle slipssideways, it can hit somethingthat will trip it – a rock, a rut,etc. – and roll over.

. Hidden obstacles can make thesteepness of the incline moresevere. If a rock is driven acrosswith the uphill wheels, or if thedownhill wheels drop into a rutor depression, the vehicle can tilteven more.

. If an incline must be drivenacross, and the vehicle starts toslide, turn downhill. This shouldhelp straighten out the vehicleand prevent the side slipping.

{ WARNING

Getting out of the vehicle on thedownhill side when stoppedacross an incline is dangerous.If the vehicle rolls over, you couldbe crushed or killed. Always getout on the uphill side of thevehicle and stay well clear of therollover path.

Driving in Mud, Sand, Snow,or Ice

Use a low gear when driving inmud – the deeper the mud, thelower the gear. Keep the vehiclemoving to avoid getting stuck.

Traction changes when driving onsand. On loose sand, such as onbeaches or sand dunes, the tirestend to sink into the sand. Thisaffects steering, accelerating, andbraking. Drive at a reduced speedand avoid sharp turns or abruptmaneuvers.

Driving and Operating 9-11

Traction is reduced on hard packedsnow and ice and it is easy to losecontrol. Reduce vehicle speed whendriving on hard packed snowand ice.

{ WARNING

Driving on frozen lakes, ponds,or rivers can be dangerous. Iceconditions vary greatly and thevehicle could fall through the ice;you and your passengers coulddrown. Drive your vehicle on safesurfaces only.

Driving in Water

{ WARNING

Driving through rushing water canbe dangerous. Deep water cansweep your vehicle downstreamand you and your passengerscould drown. If it is only shallowwater, it can still wash away theground from under your tires.Traction could be lost, and thevehicle could roll over. Do notdrive through rushing water.

Notice: Do not drive throughstanding water if it is deepenough to cover the wheel hubs,axles or exhaust pipe. Deep watercan damage the axle and othervehicle parts.

If the standing water is not too deep,drive slowly through it. At fasterspeeds, water splashes on theignition system and the vehicle canstall. Stalling can also occur if youget the exhaust pipe under water.

While the exhaust pipe is underwater, you will not be able to startthe engine. When going throughwater, the brakes get wet, and itmight take longer to stop. SeeDriving on Wet Roads.

After Off-Road Driving

Remove any brush or debris thathas collected on the underbody orchassis, or under the hood. Theseaccumulations can be a fire hazard.

After operation in mud or sand,have the brake linings cleaned andchecked. These substances cancause glazing and uneven braking.Check the body structure, steering,suspension, wheels, tires, andexhaust system for damage andcheck the fuel lines and coolingsystem for any leakage.

More frequent maintenanceservice is required. Refer to theMaintenance Schedule for moreinformation.

9-12 Driving and Operating

Driving on Wet RoadsRain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep‐standing or flowing water.

{ WARNING

Wet brakes can cause crashes.They might not work as well in aquick stop and could causepulling to one side. You couldlose control of the vehicle.

After driving through a largepuddle of water or a car/vehiclewash, lightly apply the brakepedal until the brakes worknormally.

(Continued)

WARNING (Continued)

Flowing or rushing water createsstrong forces. Driving throughflowing water could cause thevehicle to be carried away. If thishappens, you and other vehicleoccupants could drown. Do notignore police warnings and bevery cautious about trying to drivethrough flowing water.

Hydroplaning

Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the road iswet enough and you are going fastenough. When the vehicle ishydroplaning, it has little or nocontact with the road.

There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.

Other Rainy Weather Tips

Besides slowing down, other wetweather driving tips include:. Allow extra following distance.. Pass with caution.. Keep windshield wiping

equipment in good shape.. Keep the windshield washer fluid

reservoir filled.. Have good tires with proper

tread depth. See Tires onpage 10‑57.

. Turn off cruise control.

Highway HypnosisAlways be alert and pay attention toyour surroundings while driving.If you become tired or sleepy, find asafe place to park the vehicleand rest.

Other driving tips include:. Keep the vehicle well ventilated.. Keep the interior

temperature cool.

. Keep your eyes moving — scanthe road ahead and to the sides.

. Check the rearview mirror andvehicle instruments often.

Hill and Mountain RoadsDriving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips fordriving in these conditions include:. Keep the vehicle serviced and in

good shape.. Check all fluid levels and brakes,

tires, cooling system, andtransmission.

. Shift to a lower gear when goingdown steep or long hills.

{ WARNING

If you do not shift down, thebrakes could get so hot that theywould not work well. You wouldthen have poor braking or evennone going down a hill. You couldcrash. Shift down to let the engineassist the brakes on a steepdownhill slope.

{ WARNING

Coasting downhill in N (Neutral)or with the ignition off isdangerous. The brakes will haveto do all the work of slowing downand they could get so hot thatthey would not work well. Youwould then have poor braking oreven none going down a hill. Youcould crash. Always have theengine running and the vehicle ingear when going downhill.

. Stay in your own lane. Do notswing wide or cut across thecenter of the road. Drive atspeeds that let you stay in yourown lane.

. Be alert on top of hills;something could be in your lane(stalled car, accident).

. Pay attention to special roadsigns (falling rocks area, windingroads, long grades, passing orno-passing zones) and takeappropriate action.

Winter Driving

Driving on Snow or Ice

Drive carefully when there is snowor ice between the tires and theroad, creating less traction or grip.Wet ice can occur at about 0°C(32°F) when freezing rain begins tofall, resulting in even less traction.Avoid driving on wet ice or infreezing rain until roads can betreated with salt or sand.

Drive with caution, whatever thecondition. Accelerate gently sotraction is not lost. Accelerating tooquickly causes the wheels to spinand makes the surface under thetires slick, so there is even lesstraction.

Try not to break the fragile traction.If you accelerate too fast, the drivewheels will spin and polish thesurface under the tires even more.

The Antilock Brake System (ABS)on page 9‑61 improves vehiclestability during hard stops onslippery roads, but apply the brakessooner than when on dry pavement.

Allow greater following distance onany slippery road and watch forslippery spots. Icy patches canoccur on otherwise clear roads inshaded areas. The surface of acurve or an overpass can remain icywhen the surrounding roads areclear. Avoid sudden steeringmaneuvers and braking whileon ice.

Turn off cruise control on slipperysurfaces.

Blizzard Conditions

Being stuck in snow can be aserious situation. Stay with thevehicle unless there is help nearby.If possible, use the RoadsideAssistance Program (U.S. andCanada) on page 13‑8 or RoadsideAssistance Program (Mexico) onpage 13‑11. To get help and keepeveryone in the vehicle safe:. Turn on the hazard warning

flashers.. Tie a red cloth to an outside

mirror.

{ WARNING

Snow can trap engine exhaustunder the vehicle. This maycause exhaust gases to getinside. Engine exhaust containscarbon monoxide (CO) whichcannot be seen or smelled. It cancause unconsciousness and evendeath.

If the vehicle is stuck in the snow:. Clear away snow from aroundthe base of your vehicle,especially any that is blockingthe exhaust pipe.

. Check again from time totime to be sure snow doesnot collect there.

. Open a window about 5 cm(2 in) on the side of thevehicle that is away from thewind to bring in fresh air.

(Continued)

WARNING (Continued)

. Fully open the air outlets onor under the instrumentpanel.

. Adjust the climate controlsystem to a setting thatcirculates the air inside thevehicle and set the fan speedto the highest setting. See“Climate Control Systems” inthe Index.

For more information aboutcarbon monoxide, see EngineExhaust on page 9‑37.

Run the engine for short periodsonly as needed to keep warm, butbe careful.

To save fuel, run the engine for onlyshort periods as needed to warmthe vehicle and then shut the engineoff and close the window most ofthe way to save heat. Repeat thisuntil help arrives but only when youfeel really uncomfortable from thecold. Moving about to keep warmalso helps.

If it takes some time for help toarrive, now and then when you runthe engine, push the acceleratorpedal slightly so the engine runsfaster than the idle speed. Thiskeeps the battery charged to restartthe vehicle and to signal for helpwith the headlamps. Do this as littleas possible to save fuel.

If the Vehicle Is StuckSlowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.See“Rocking Your Vehicle to Get ItOut” later in this section.

If the vehicle has a traction system,it can often help to free a stuckvehicle. Refer to the vehicle'straction system in the Index. If stucktoo severely for the traction systemto free the vehicle, turn the tractionsystem off and use the rockingmethod.

{ WARNING

If the vehicle's tires spin at highspeed, they can explode, and youor others could be injured. Thevehicle can overheat, causing anengine compartment fire or otherdamage. Spin the wheels as littleas possible and avoid goingabove 56 km/h (35 mph).

For information about using tirechains on the vehicle, see TireChains on page 10‑81.

Rocking Your Vehicle to GetIt Out

Turn the steering wheel left andright to clear the area around thefront wheels. For four-wheel-drivevehicles, shift into Four‐Wheel High.For vehicles with StabiliTrak®, turnthe traction control part of thesystem off. Shift back and forthbetween R (Reverse) and a forwardgear, spinning the wheels as little aspossible. To prevent transmissionwear, wait until the wheels stopspinning before shifting gears.

Release the accelerator pedal whileshifting, and press lightly on theaccelerator pedal when thetransmission is in gear. Slowlyspinning the wheels in the forwardand reverse directions causes arocking motion that could free thevehicle. If that does not get thevehicle out after a few tries, it mightneed to be towed out. Recoveryhooks can be used, if the vehiclehas them. If the vehicle does needto be towed out, see Towing theVehicle on page 10‑101.

Recovery Hooks

{ WARNING

Never pull on recovery hooksfrom the side. The hooks couldbreak and you and others couldbe injured. When using recoveryhooks, always pull the vehiclestraight out.

2. Determine the combinedweight of the driver andpassengers that will be ridingin your vehicle.

3. Subtract the combinedweight of the driver andpassengers from XXX kg orXXX lbs.

4. The resulting figure equalsthe available amount of cargoand luggage load capacity.For example, if the “XXX”amount equals 1400 lbs andthere will be five 150 lbpassengers in your vehicle,the amount of available cargoand luggage load capacity is650 lbs (1400−750 (5x150) =650 lbs).

5. Determine the combinedweight of luggage and cargobeing loaded on the vehicle.That weight may not safelyexceed the available cargoand luggage load capacitycalculated in Step 4.

6. If your vehicle will be towinga trailer, the load from yourtrailer will be transferred toyour vehicle. Consult thismanual to determine how thisreduces the available cargoand luggage load capacity ofyour vehicle. See TrailerTowing on page 9‑90 forimportant information ontowing a trailer, towing safetyrules and trailering tips.

Refer to your vehicle's tire andloading information label forspecific information about yourvehicle's capacity weight andseating positions. The combinedweight of the driver, passengers,and cargo should never exceedyour vehicle's capacity weight.

Certification/Tire Label

A vehicle specific Certification/Tire label is found on the rearedge of the driver door. Thelabel shows the size of yourvehicle's original tires and theinflation pressures needed toobtain the gross weight capacity

of your vehicle. This is calledGross Vehicle WeightRating (GVWR). The GVWRincludes the weight of thevehicle, all occupants, fuel,and cargo.

The Certification/Tire label alsotells you the maximum weightsfor the front and rear axles,called Gross Axle WeightRating (GAWR). To find out theactual loads on your front andrear axles, you need to go to aweigh station and weigh yourvehicle. Your dealer can helpyou with this. Be sure to spreadout your load equally on bothsides of the centerline.

There is also important loadinginformation for off-road driving inthis manual. See “LoadingYour Vehicle for Off-RoadDriving“under Off-Road Drivingon page 9‑6.

Two-Tiered Loading

Depending on the model of yourpick‐up, an upper load platformcan be created by positioningthree or four 5 cm (2 inches) by15 cm (6 inches) wooden planksacross the width of the pickupbox. The planks must beinserted in the pickup boxdepressions.

When using this upper loadplatform, be sure the load issecurely tied down to prevent itfrom shifting. The load's centerof gravity should be positionedin a zone over the rear axle. Thezone is located in the areabetween the front of each wheelwell and the rear of each wheelwell. The center of gravity heightmust not extend above the topof the pickup box flareboard.

Any load that extends beyondthe vehicle's taillamp area mustbe properly marked according tolocal laws and regulations.

Remember not to exceedthe Gross Axle WeightRating (GAWR) of the front orrear axle.

Truck-Camper LoadingInformationA vehicle-specific Truck‐CamperLoading Information label isattached to the inside of thevehicle's glove box. This labelindicates if a slide-in campercan be carried, how much of aload the vehicle can carry, andhow to correctly spread out theload. It will help to match theright slide in camper to thevehicle.

Your dealer can help make agood vehicle-camper match andhelp determine the CargoWeight Rating (CWR).

When installing and loading aslide-in camper, check themanufacturer's instructions.

When carrying a slide-incamper, the total cargo load ofthe vehicle is the weight of thecamper, plus the following:. Everything added to the

camper after it left the factory. Everything in the camper. All the people inside

The CWR is the maximumweight of the load the vehiclecan carry. It does not include theweight of the people inside. But,use about 68 kg (150 lbs) foreach seat.

The total cargo load must not bemore than the vehicle's CWR.

Refer to the Truck-CamperLoading Information label in theglove box for dimensions A andB as shown in the followingillustration.

Use the rear edge of the loadfloor for measurement purposes.The recommended location forthe cargo center of gravity is atpoint C for the CWR. It is thepoint where the mass ofa body is concentrated and,if suspended at that point, wouldbalance the front and rear.

9-26 Driving and Operating

Here is an example of propertruck and camper match:

A. Camper Center of Gravity

B. Recommended Center ofGravity Location Zone

When the truck is used to carrya slide‐in camper, the total cargoload of the truck consists of themanufacturer's camper weightfigure, the weight of installedadditional camper equipment notincluded in the manufacturer'scamper weight figure, the weight

of camper cargo, and the weightof passengers in the camper.The total cargo load should notexceed the truck's cargo weightrating, and the camper's centerof gravity (A) should fall withinthe truck's recommended centerof gravity zone (B) wheninstalled.

Any accessories or otherequipment that are added to thevehicle must be weighed. Then,subtract this extra weight fromthe CWR. This extra weight mayshorten the center of gravityzone of the vehicle.

If the slide-in camper and itsload weighs less than the CWR,the center of gravity zone foryour vehicle may be larger.

Secure loose items to preventweight shifts that could affect thebalance of the vehicle. When thetruck‐camper is loaded, drive toa scale and weigh on the front

and on the rear wheelsseparately to determine axleloads. Individual axle loadsshould not exceed either of thegross axle weight ratings(GAWR). The total axle loadsshould not exceed your vehicle'sgross vehicle weight rating(GVWR). These ratings aregiven on the vehicle certificationlabel attached to the rearedge of the driver door. See“Certification/Tire Label” underVehicle Load Limits onpage 9‑17. If weight ratings areexceeded, move or removeitems to bring all weights belowthe ratings.

See your dealer for moreinformation on curb weights,cargo weights, Cargo WeightRating and the correct center ofgravity zone.

P (Park): This position locks therear wheels. It is the best position touse when starting the enginebecause the vehicle cannot moveeasily. When parked on a hill,especially when the vehicle has aheavy load, you might notice anincrease in the effort to shift out ofP (Park). See “Torque Lock” underShifting Into Park on page 9‑34 formore information.

{ WARNING

It is dangerous to get out of thevehicle if the shift lever is not fullyin P (Park) with the parking brakefirmly set. The vehicle can roll.

Do not leave the vehicle when theengine is running unless youhave to. If you have left theengine running, the vehicle canmove suddenly. You or otherscould be injured. To be sure thevehicle will not move, even whenyou are on fairly level ground,always set the parking brake andmove the shift lever to P (Park).See Shifting Into Park onpage 9‑34. If you are pulling atrailer, see Driving Characteristicsand Towing Tips on page 9‑86.

{ WARNING

If you have Four-Wheel Drive, thevehicle will be free to roll— evenif the shift lever is in P (Park)— ifthe transfer case is in Neutral. So,be sure the transfer case is in adrive gear, Two-Wheel Drive Highor Four-Wheel Drive High orFour-Wheel Drive Low— not inNeutral. See Shifting Into Park onpage 9‑34.

R (Reverse): Use this gear toback up.

Notice: Shifting to R (Reverse)while the vehicle is movingforward could damage thetransmission. The repairs wouldnot be covered by the vehiclewarranty. Shift to R (Reverse) onlyafter the vehicle is stopped.

N (Neutral): In this position, theengine does not connect with thewheels. To restart when you arealready moving, use N (Neutral)only. Also, use N (Neutral) when thevehicle is being towed.

{ WARNING

Shifting into a drive gear while theengine is running at high speed isdangerous. Unless your foot isfirmly on the brake pedal, thevehicle could move very rapidly.You could lose control and hitpeople or objects. Do not shiftinto a drive gear while the engineis running at high speed.

Notice: Shifting out of P (Park) orN (Neutral) with the enginerunning at high speed maydamage the transmission. Therepairs would not be covered bythe vehicle warranty. Be sure theengine is not running at highspeed when shifting the vehicle.

D (Drive): This position is fornormal driving. It provides the bestfuel economy. If you need morepower for passing, and you are:. Going less than about 55 km/h

(35 mph), push the acceleratorpedal about halfway down.

. Going about 55 km/h (35 mph) ormore, push the accelerator allthe way down.

By doing this, the vehicle shiftsdown to the next gear and hasmore power.

D (Drive) can be used when towinga trailer, carrying a heavy load,driving on steep hills, or for off-roaddriving. You might want to shift thetransmission to a lower gearselection if the transmission shiftstoo often.

Downshifting the transmission inslippery road conditions could resultin skidding. See “Skidding” underLoss of Control on page 9‑5.

The vehicle has a shift stabilizationfeature that adjusts the transmissionshifting to the current drivingconditions in order to reduce rapidupshifts and downshifts. This shiftstabilization feature is designed todetermine, before making anupshift, if the engine is able tomaintain vehicle speed by analyzingthings such as vehicle speed,throttle position, and vehicle load.If the shift stabilization featuredetermines that a current vehiclespeed cannot be maintained, thetransmission does not upshift andinstead holds the current gear.In some cases, this could appear tobe a delayed shift, however thetransmission is operating normally.

9-42 Driving and Operating

The transmission uses adaptiveshift controls. Adaptive shift controlscontinually compares key shiftparameters to pre-programmedideal shifts stored in thetransmissions computer. Thetransmission constantly makesadjustments to improve vehicleperformance according to how thevehicle is being used, such as witha heavy load or when temperaturechanges. During this adaptive shiftcontrol process, shifting might feeldifferent as the transmissiondetermines the best settings.

When temperatures are very cold,the Allison Transmission andHydra-Matic 6-Speed transmission'sgear shifting could be delayedproviding more stable shifts until theengine warms up. Shifts could bemore noticeable with a coldtransmission. This difference inshifting is normal.

M (Manual Mode): This position isavailable on vehicles with theAllison Transmission or Hydra-Matic6-Speed transmission. It letsdrivers select the range of gearsappropriate for current drivingconditions. If the vehicle has thisfeature, see “Range SelectionMode” under Manual Mode onpage 9‑43.

3 (Third): This position is also usedfor normal driving. It reduces vehiclespeed more than D (Drive) withoutusing the brakes. You might choose3 (Third) instead of D (Drive) whendriving on hilly, winding roads, whentowing a trailer, so there is lessshifting between gears and whengoing down a steep hill.

2 (Second): This position reducesvehicle speed even more than3 (Third) without using the brakes.You can use 2 (Second) on hills.It can help control vehicle speed asyou go down steep mountain roads,but then you would also want to usethe brakes off and on.

If you manually select 2 (Second) inan automatic transmission, thetransmission will start in secondgear. You can use this feature forreducing the speed of the rearwheels when you are trying to startthe vehicle from a stop on slipperyroad surfaces.

1 (First): For the Hydra-Matic4-Speed transmission this positionreduces vehicle speed even morethan 2 (Second) without using thebrakes. You can use it on very steephills, or in deep snow or mud. If theshift lever is put in 1 (First) while thevehicle is moving forward, thetransmission does not shift into firstgear until the vehicle is going slowlyenough.

For an Allison Transmission orHydra-Matic 6-Speed transmission,this position reduces vehicle speedwithout using the brakes. You canuse it for major/severe downgradesand off-road driving where thevehicle would otherwise acceleratedue to steepness of grade. Whenyou shift to 1 (First) it provides thelowest gear appropriate to currentroad speed and continues todownshift as the vehicle slows,eventually downshifting to1 (First) gear.

Notice: Spinning the tires orholding the vehicle in oneplace on a hill using only theaccelerator pedal may damagethe transmission. The repair willnot be covered by the vehiclewarranty. If you are stuck, do notspin the tires. When stopping ona hill, use the brakes to hold thevehicle in place.

Manual Mode

Range Selection Mode(Allison® Transmission orHydra-Matic® 6-SpeedTransmission)

The vehicle may have a RangeSelection Mode. The RangeSelection Mode helps control thevehicle's transmission and vehiclespeed while driving down hill ortowing a trailer by letting you selecta desired range of gears.

To use this feature, do the following:

1. Move the shift lever toM (Manual Mode).

2. Press the plus/minus buttons,located on the steering columnshift lever, to select the desiredrange of gears for current drivingconditions.

When M (Manual Mode) is selecteda number displays next to the M,indicating the current gear.

This number is the highest gear thatcan be used. However, the vehiclecan automatically shift to lowergears as it adjusts to drivingconditions. This means that allgears below that number areavailable. When 5 (Fifth) is selected,1 (First) through 5 (Fifth) gears areautomatically shifted by the vehicle,but 6 (Sixth) cannot be used untilthe plus/minus button located on thesteering column lever is used tochange to the gear.

Driving and Operating 9-57

Excessively shifting the transfercase into or out of the differentmodes may cause the transfer caseto enter the shift protection mode.This will protect the transfer casefrom possible damage and will onlyallow the transfer case to respond toone shift per 10 seconds. Thetransfer case may stay in this modefor up to three minutes.

Automatic Transfer Case

The transfer case knob is locatednext to the steering column.

Use the dial to shift into and out ofFour-Wheel Drive.

You can choose among five drivingsettings:

Indicator lights in the dial showwhich setting you are in. Theindicator lights will come on brieflywhen you turn on the ignition andone will stay on. If the lights do notcome on, you should take thevehicle to your dealer for service.An indicator light will flash whileshifting the transfer case. It willremain illuminated when the shift iscomplete. If for some reason thetransfer case cannot make arequested shift, it will return to thelast chosen setting.

2 m (Two-Wheel Drive High): Thissetting is used for driving in moststreet and highway situations. Thefront axle is not engaged inTwo-Wheel Drive. This setting alsoprovides the best fuel economy.

AUTO (Automatic Four-WheelDrive): This setting is ideal for usewhen road surface tractionconditions are variable. Whendriving the vehicle in AUTO, thefront axle is engaged, but thevehicle's power is sent only to thefront and rear wheels automaticallybased on driving conditions. Drivingin this mode results in slightly lowerfuel economy than Two-WheelDrive High.

4 m (Four-Wheel Drive High): Usethe Four-Wheel Drive High positionwhen extra traction is needed, suchas on snowy or icy roads or in mostoff-road situations. This setting alsoengages the front axle to help drivethe vehicle. This is the best settingto use when plowing snow.

Brakes

Antilock BrakeSystem (ABS)This vehicle might have the AntilockBrake System (ABS), an advancedelectronic braking system that helpsprevent a braking skid.

When the engine is started and thevehicle begins to drive away, ABSchecks itself. A momentary motor orclicking noise might be heard whilethis test is going on. This is normal.

If there is a problem with ABS, thiswarning light stays on. See AntilockBrake System (ABS) Warning Lighton page 5‑28.

Along with ABS, the vehicle has aDynamic Rear Proportioning (DRP)system. If there is a DRP problem,both the brake and ABS warninglights come on accompanied by a10‐second chime. The lights andchime will come on each time theignition is turned on until theproblem is repaired. See your dealerfor service.

Let us say the road is wet and youare driving safely. Suddenly, ananimal jumps out in front of you.You slam on the brakes andcontinue braking. Here is whathappens with ABS:

A computer senses that the wheelsare slowing down. If one of thewheels is about to stop rolling, thecomputer will separately work thebrakes at each front wheel and atboth rear wheels.

Page 362: 2012 Chevrolet Silverado Owner Manual M - General Motors · Chevrolet Silverado Owner Manual - 2012 Black plate (3,1) Introduction iii The names, logos, emblems, slogans, vehicle

Black plate (62,1)Chevrolet Silverado Owner Manual - 2012

9-62 Driving and Operating

ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpthe driver steer around the obstaclewhile braking hard.

As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.

Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehiclesuddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.

Using ABS

Do not pump the brakes. Just holdthe brake pedal down firmly and letantilock work. You might feel thebrakes vibrate or hear some noise,but this is normal.

Braking in Emergencies

If the vehicle has ABS, it allows thedriver to steer and brake at thesame time. However, if the vehicledoes not have ABS, the firstreaction, to hit the brake pedal hardand hold it down, might be thewrong thing to do. The wheels canstop rolling. Once they do, thevehicle cannot respond to thedriver's steering. Momentum willcarry it in whatever direction it washeaded when the wheels stoppedrolling. That could be off the road,into the very thing the driver wastrying to avoid, or into traffic.

If the vehicle does not have ABS,use a squeeze braking technique.This gives maximum braking whilemaintaining steering control. Do thisby pushing on the brake pedal withsteadily increasing pressure.

In an emergency, you will probablywant to squeeze the brakes hardwithout locking the wheels. If youhear or feel the wheels sliding, easeoff the brake pedal. This helpsretain steering control. With ABS, itis different.

In many emergencies, steering canhelp more than even the very bestbraking.

Brake AssistIf this vehicle has StabiliTrak®, italso has a Brake Assist featuredesigned to assist the driver instopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplement thepower brake system underconditions where the driver has

quickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle. Thestability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.Minor brake pedal pulsation orpedal movement during this time isnormal and the driver shouldcontinue to apply the brake pedal asthe driving situation dictates TheBrake Assist feature willautomatically disengage when thebrake pedal is released or brakepedal pressure is quicklydecreased.

Hill Start Assist (HSA)Non‐hybrid vehicles with StabiliTrakhave a Hill Start Assist (HSA)feature, which may be useful whenthe vehicle is stopped on a grade.This feature is designed to preventthe vehicle from rolling, eitherforward or rearward, during vehicledrive off. After the driver completelystops and holds the vehicle in acomplete standstill on a grade, HSAwill be automatically activated.During the transition period betweenwhen the driver releases the brakepedal and starts to accelerate todrive off on a grade, HSA holds thebraking pressure for a maximum oftwo seconds to ensure that there is

no rolling. The brakes willautomatically release when theaccelerator pedal is applied withinthe two‐second window. If thevehicle is equipped with theIntegrated Trailer Brake Control(ITBC) system, HSA may also applythe trailer brakes. It will not activateif the vehicle is in a drive gear andfacing downhill or if the vehicle isfacing uphill and in R (Reverse).There may be situations on minorhills (less than 5% grade) with aloaded vehicle or while pulling atrailer where HSA will not activate.

Ride Control Systems

StabiliTrak® SystemThe vehicle has a vehicle stabilityenhancement system calledStabiliTrak. It is an advancedcomputer-controlled system thatassists the driver with directionalcontrol of the vehicle in difficultdriving conditions.

StabiliTrak activates when thecomputer senses a discrepancybetween the intended path and thedirection the vehicle is actuallytraveling. StabiliTrak selectivelyapplies braking pressure at any oneof the vehicle's brakes to assist thedriver with keeping the vehicle onthe intended path.

9-68 Driving and Operating

Traction Control Operation

The TCS is part of the StabiliTraksystem. Traction control limits wheelspin by reducing engine power tothe wheels (engine speedmanagement) and by applyingbrakes to each individual wheel(brake-traction control) asnecessary.

The TCS is enabled automaticallywhen the vehicle is started. It willactivate and the StabiliTrak light willflash if it senses that any of thewheels are spinning or beginning tolose traction while driving. If tractioncontrol is turned off, only thebrake-traction control portion oftraction control will work. Theengine speed management will bedisabled. In this mode, enginepower is not reduced automaticallyand the driven wheels can spinmore freely. This can cause thebrake-traction control to activateconstantly.

Notice: If the wheel(s) of one axleis allowed to spin excessivelywhile the StabiliTrak®, ABS, brakewarning lights, and any relevantDIC messages are displayed, thetransfer case could be damaged.The repairs would not be coveredby the vehicle warranty. Reduceengine power and do not spin thewheel(s) excessively while theselights and messages aredisplayed.

The TCS may activate on dry orrough roads or under conditionssuch as heavy acceleration whileturning or abrupt upshifts/downshiftsof the transmission. When thishappens, a reduction in accelerationmay be noticed, or a noise orvibration may be heard. This isnormal.

If cruise control is being used whenthe system activates, the StabiliTraklight will flash and cruise control willautomatically disengage. Cruisecontrol may be reengaged whenroad conditions allow. See CruiseControl on page 9‑69.

StabiliTrak may also turn offautomatically if it determines that aproblem exists with the system.If the problem does not clear itselfafter restarting the vehicle, see yourdealer for service.

Non-hybrid vehicles with StabiliTrakhave a Trailer Sway Control (TSC)feature. See Trailer Sway Control(TSC) on page 9‑118.

Non-hybrid vehicles with StabiliTrakhave a Hill Start Assist (HSA)feature. See Hill Start Assist (HSA)on page 9‑65.

The URPA system does notdetect pedestrians, bicyclists,animals, or any other objectslocated below the bumper or thatare too close or too far from thevehicle. To prevent injury, death,or vehicle damage, even withURPA, always check the areaaround the vehicle and check allmirrors before backing.

How the System Works

URPA comes on automatically whenthe shift lever is moved intoR (Reverse). A single tone soundsto indicate the system is working.

URPA operates only at speeds lessthan 8 km/h (5 mph).

An obstacle is indicated by audiblebeeps. The interval between thebeeps becomes shorter as thevehicle gets closer to the obstacle.

Fuel AdditivesTo provide cleaner air, all gasolinesin the United States are nowrequired to contain additives thathelp prevent engine and fuel systemdeposits from forming, allowing theemission control system to workproperly. In most cases, nothingshould have to be added to the fuel.However, some gasolines containonly the minimum amount ofadditive required to meet U.S.Environmental Protection Agencyregulations. To help keep fuelinjectors and intake valves cleanand avoid problems due to dirtyinjectors or valves, look for gasolinethat is advertised as TOP TIERDetergent Gasoline. Look for theTOP TIER label on the fuel pump toensure gasoline meets enhanceddetergency standards developed bythe auto companies. A list ofmarketers providing TOP TIERDetergent Gasoline can be found atwww.toptiergas.com.

For customers who do not use TOPTIER Detergent Gasoline regularly,one bottle of GM Fuel SystemTreatment PLUS, added to the fueltank at every engine oil change, canhelp clean deposits from fuelinjectors and intake valves. GM FuelSystem Treatment PLUS is the onlygasoline additive recommended byGeneral Motors. It is available atyour dealer.

Gasolines containing oxygenates,such as ethers and ethanol, andreformulated gasolines might beavailable in your area. Werecommend that you use thesegasolines, if they comply with thespecifications described earlier.However, E85 (85% ethanol) andother fuels containing more than15% ethanol must not be used invehicles that were not designed forthose fuels.

Notice: This vehicle was notdesigned for fuel that containsmethanol. Do not use fuelcontaining methanol. It cancorrode metal parts in the fuelsystem and also damage plasticand rubber parts. That damagewould not be covered under thevehicle warranty.

Some gasolines that arenot reformulated for lowemissions can contain anoctane-enhancing additive calledmethylcyclopentadienyl manganesetricarbonyl (MMT); ask the attendantwhere you buy gasoline whether thefuel contains MMT. We recommendagainst the use of such gasolines.Fuels containing MMT can reducespark plug life and affect emissioncontrol system performance. Themalfunction indicator lamp mightturn on. If this occurs, return to yourdealer for service.

Fuel E85 (85% Ethanol)Vehicles that have a FlexFuel badgeand a yellow fuel cap can use eitherunleaded gasoline or ethanol fuelcontaining up to 85% ethanol (E85).For all other vehicles, use only theunleaded gasoline described underRecommended Fuel on page 9‑80.

We encourage the use of E85 invehicles that are designed to use it.The ethanol in E85 is a “renewable”fuel, meaning it is made fromrenewable sources such as cornand other crops.

Many service stations will not havean 85% ethanol fuel (E85) pumpavailable. The U.S. Department ofEnergy has an alternative fuelswebsite (www.afdc.energy.gov/afdc/locator/stations/) that can help youfind E85 fuel. Those stations that dohave E85 should have a labelindicating ethanol content. Do notuse the fuel if the ethanol content isgreater than 85%.

At a minimum, E85 should meetASTM Specification D 5798 orCGSB Specification 3.512. Fillingthe tank with fuel mixtures that donot meet ASTM or CGSBspecifications can affect driveabilityand could cause the malfunctionindicator lamp to come on. As theoutside temperature approachesfreezing, ethanol fuel distributorsshould supply winter grade ethanol,the same as with unleadedgasoline.

It is best not to alternate repeatedlybetween gasoline and E85. If youdo switch fuels, it is recommendedthat you add as much fuel aspossible — do not add less than11 L (3 gal) when refueling. Youshould drive the vehicle immediatelyafter refueling for at least 11 km(7 mi) to allow the vehicle to adaptto the change in ethanolconcentration.

E85 has less energy per liter(gallon) than gasoline, so you willneed to refill the fuel tank moreoften when using E85 than whenyou are using gasoline. See Fillingthe Tank on page 9‑84.

Notice: Some additives are notcompatible with E85 fuel and canharm the vehicle's fuel system.Do not add anything to E85.Damage caused by additiveswould not be covered by thevehicle warranty.

Notice: This vehicle was notdesigned for fuel that containsmethanol. Do not use fuelcontaining methanol. It cancorrode metal parts in the fuelsystem and also damage plasticand rubber parts. That damagewould not be covered under thevehicle warranty.

Towing

General TowingInformationOnly use towing equipment that hasbeen designed for the vehicle.Contact your dealer or traileringdealer for assistance with preparingthe vehicle for towing a trailer.

See the following trailer towinginformation in this section:. For information on driving while

towing a trailer, see “DrivingCharacteristics andTowing Tips.”

. For maximum vehicle and trailerweights, see “Trailer Towing.”

. For information on equipment totow a trailer, see “TowingEquipment.”

For information on towing a disabledvehicle, see Towing the Vehicle onpage 10‑101. For information ontowing the vehicle behind anothervehicle such as a motor home, seeRecreational Vehicle Towing onpage 10‑101.

Driving Characteristicsand Towing Tips

Pulling a Trailer

Important points for pulling a trailer:. There are many different laws,

including speed limit restrictions,having to do with trailering.Make sure the rig will be legal,not only where you live but alsowhere you will be driving.A good source for thisinformation can be state orprovincial police.

. Consider using a sway control.See “Hitches” under TowingEquipment on page 9‑106.

. Do not tow a trailer at all duringthe first 800 km (500 miles) thenew vehicle is driven. Theengine, axle, or other parts couldbe damaged.

. During the first 800 km(500 miles) that a trailer istowed, do not drive over 80 km/h(50 mph) and do not make startsat full throttle. This helps theengine and other parts of thevehicle wear in at the heavierloads.

. Vehicles can tow in D (Drive).Shift the transmission to a lowergear if the transmission shiftstoo often under heavy loads and/or hilly conditions.

Important considerations that haveto do with weight:. Weight of the trailer. Weight of the trailer tongue. Weight on the vehicle's tires. Weight of the trailering

combination

Driving with a Trailer

{ WARNING

When towing a trailer, exhaustgases may collect at the rear ofthe vehicle and enter if theliftgate, trunk/hatch, or rear-mostwindow is open.

Engine exhaust contains CarbonMonoxide (CO) which cannot beseen or smelled. It can causeunconsciousness and even death.

To maximize safety when towinga trailer:

. Have the exhaust systeminspected for leaks and makenecessary repairs beforestarting a trip.

. Never drive with the liftgate,trunk/hatch, or rear-mostwindow open.

(Continued)

WARNING (Continued)

. Fully open the air outlets onor under the instrumentpanel.

. Adjust the Climate Controlsystem to a setting thatbrings in only outside air andset the fan speed to thehighest setting. See ClimateControl System in the Index.

For more information aboutCarbon Monoxide, see EngineExhaust on page 9‑37.

Towing a trailer requires a certainamount of experience. Thecombination you are driving islonger and not as responsive as thevehicle itself. Get acquainted withthe handling and braking of the rigbefore setting out for the open road.

Before starting, check all trailer hitchparts and attachments, safetychains, electrical connectors, lamps,tires, and mirrors. If the trailerhas electric brakes, start thecombination moving and then applythe trailer brake controller by handto be sure the brakes work.

During the trip, check occasionallyto be sure that the load is secureand the lamps and any trailerbrakes still work.

Following Distance

Stay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid heavybraking and sudden turns.

9-88 Driving and Operating

Passing

More passing distance is neededwhen towing a trailer. Thecombination will not accelerate asquickly and is longer so it isnecessary to go much fartherbeyond the passed vehicle beforereturning to the lane.

Backing Up

Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that hand tothe left. To move the trailer to theright, move your hand to the right.Always back up slowly and,if possible, have someoneguide you.

Making Turns

Notice: Making very sharp turnswhile trailering could cause thetrailer to come in contact with thevehicle. The vehicle could bedamaged. Avoid making verysharp turns while trailering.

When turning with a trailer, makewider turns than normal. Do this sothe trailer will not strike softshoulders, curbs, road signs, trees,or other objects. Avoid jerky orsudden maneuvers. Signal well inadvance.

If the trailer turn signal bulbs burnout, the arrows on the instrumentpanel will still flash for turns. It isimportant to check occasionally tobe sure the trailer bulbs are stillworking.

Driving on Grades

Reduce speed and shift to a lowergear before starting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might get hot and no longerwork well.

Vehicles can tow in D (Drive). Shiftthe transmission to a lower gear ifthe transmission shifts too oftenunder heavy loads and/or hillyconditions.

The Tow/Haul Mode may be used ifthe transmission shifts too often.See Tow/Haul Mode on page 9‑44.

When towing at high altitude onsteep uphill grades, consider thefollowing: Engine coolant will boil ata lower temperature than at normalaltitudes. If the engine is turned offimmediately after towing at highaltitude on steep uphill grades, thevehicle may show signs similar toengine overheating. To avoid this,let the engine run while parked,preferably on level ground, with theautomatic transmission in P (Park)for a few minutes before turning theengine off. If the overheat warningcomes on, see Engine Overheatingon page 10‑24.

To identify the trailering capacity ofthe vehicle, read the information in“Weight of the Trailer” later in thissection.

Trailering is different than justdriving the vehicle by itself.Trailering means changes inhandling, acceleration, braking,durability, and fuel economy.Successful, safe trailering takescorrect equipment, and it has to beused properly.

The following information has manytime-tested, important trailering tipsand safety rules. Many of these areimportant for your safety and that ofyour passengers. So please readthis section carefully before pulling atrailer.

Weight of the Trailer

How heavy can a trailer safely be?

It depends on how the rig is used.Speed, altitude, road grades,outside temperature, and how muchthe vehicle is used to pull a trailerare all important. It can depend onany special equipment on thevehicle, and the amount of tongueweight the vehicle can carry. See“Weight of the Trailer Tongue” laterin this section for more information.

Trailer weight rating (TWR) iscalculated assuming the tow vehiclehas only the driver but all requiredtrailering equipment. Weight ofadditional optional equipment,passengers, and cargo in the towvehicle must be subtracted from thetrailer weight rating.

For kingpin weight and trailertongue weight information, see“Weight of the Trailer Tongue” laterin this section.

Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle model andoptions.

Weights listed apply forconventional trailers and fifth-wheeltrailers unless otherwise noted.

Trailering may be limited by thevehicle's ability to carry tongueweight. Tongue or kingpin weightcannot cause the vehicle to exceedthe GVWR (Gross Vehicle WeightRating) or the RGAWR (Rear GrossAxle Weight Rating). See “TotalWeight on the Vehicle's Tires” laterin this section for more information.

After loading the trailer, weigh thetrailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving someitems around in the trailer.

Total Weight on the Vehicle'sTires

Be sure the vehicle's tires areinflated to the inflation pressuresfound on the Certification Tire labelon the drivers door or see VehicleLoad Limits on page 9‑17 for moreinformation. Make sure not toexceed the GVWR limit for thevehicle, or the RGAWR, with the towvehicle and trailer fully loaded forthe trip including the weight of the

trailer tongue. If using aweight-distributing hitch, make surenot to exceed the RGAWR beforeapplying the weight distributionspring bars.

Weight of the TraileringCombination

It is important that the combinationof the tow vehicle and trailer doesnot exceed any of its weightratings — GCWR, GVWR, RGAWR,Trailer Weight Rating, or TongueWeight. The only way to be sure it isnot exceeding any of these ratingsis to weigh the tow vehicle andtrailer combination, fully loaded forthe trip, getting individual weightsfor each of these items.

Towing Equipment

Hitches

The correct hitch equipment helpsmaintain combination control. Manytrailers can be towed with aweight-carrying hitch which simplyfeatures a coupler latched to the

hitch ball, or a tow eye latched to apintle hook. Other trailers mayrequire a weight-distributing hitchthat uses spring bars to distributethe trailer tongue weight among thetwo vehicle and trailer axles.Fifth-wheel and gooseneck hitchesmay also be used. See “Weight ofthe Trailer Tongue” under TrailerTowing on page 9‑90 for rating limitswith various hitch types.

If a step-bumper hitch will be used,the bumper could be damaged insharp turns. Make sure thereis ample room when turning to avoidcontact between the trailer and thebumper.

Consider using sway controls withany trailer. Ask a traileringprofessional about sway controls orrefer to the trailer manufacturer'srecommendations and instructions.

Weight-Distributing HitchAdjustment

A. Body to Ground Distance

B. Front of Vehicle

When using a weight-distributinghitch, the spring bars should beadjusted so the distance (A) is thesame after coupling the trailer to thetow vehicle and adjusting the hitch.

Fifth-Wheel and GooseneckTrailering

Fifth-wheel and gooseneck trailerscan be used with many pickupmodels. These trailers place alarger percentage of the weight(kingpin weight) on the tow vehiclethan conventional trailers. Makesure this weight does not cause thevehicle to exceed GAWR or GVWR.

Fifth-wheel or gooseneck kingpinweight should be 15 to 25 percent ofthe trailer weight up to the maximumamount specified in the traileringchart for the vehicle. See “Weight ofthe Trailer” under Trailer Towing onpage 9‑90 for more information.

The hitch should be located in thepickup bed so that its centerline isover or slightly in front of the rearaxle. Take care that it is not so farforward that it will contact the backof the cab in sharp turns. This isespecially important for short boxpickups. Trailer pin box extensionsand sliding fifth-wheel hitchassemblies can help this condition.There should be at least six inchesof clearance between the top of thepickup box and the bottom of thetrailer shelf that extends overthe box.

Make sure the hitch is attached tothe tow vehicle frame rails. Do notuse the pickup box for support.

Safety Chains

Always attach chains between thevehicle and the trailer. Cross thesafety chains under the tongue ofthe trailer to help prevent the tonguefrom contacting the road if itbecomes separated from the hitch.Instructions about safety chainsmay be provided by the hitchmanufacturer or by the trailermanufacturer. If the trailer beingtowed weighs up to 2 271 kg(5,000 lbs) with a factory-installedstep bumper, safety chains may beattached to the attaching points onthe bumper; otherwise, safetychains should be attached to holeson the trailer hitch platform. Alwaysleave just enough slack so thecombination can turn. Never allowsafety chains to drag on the ground.

Trailer Brakes

A loaded trailer that weighs morethan 900 kg (2,000 lbs) needs tohave its own brake system that isadequate for the weight of thetrailer. Be sure to read and followthe instructions for the trailer brakesso they are installed, adjusted, andmaintained properly.

Do not tap into the vehicle'shydraulic brake system.

Tow/Haul is designed to be mosteffective when the vehicle andtrailer combined weight is at least75 percent of the vehicle's GrossCombined Weight Rating (GCWR).See “Weight of the Trailer” underTrailer Towing on page 9‑90.Tow/Haul is most useful under thefollowing driving conditions:. When pulling a heavy trailer or a

large or heavy load throughrolling terrain.

. When pulling a heavy trailer or alarge or heavy load instop-and-go traffic.

. When pulling a heavy trailer or alarge or heavy load in busyparking lots where improved lowspeed control of the vehicle isdesired.

Operating the vehicle in Tow/Haulwhen lightly loaded or with no trailerat all will not cause damage.However, there is no benefit to theselection of Tow/Haul when thevehicle is unloaded. Such aselection when unloaded mayresult in unpleasant engine andtransmission driving characteristicsand reduced fuel economy.Tow/Haul is recommended onlywhen pulling a heavy trailer or alarge or heavy load.

Integrated Trailer BrakeControl System

The vehicle may have an IntegratedTrailer Brake Control (ITBC) systemfor electric trailer brakes.

This symbol is located on the TrailerBrake Control Panel on vehicleswith an Integrated Trailer BrakeControl system. The power output tothe trailer brakes is based on theamount of brake pressure beingapplied by the vehicle’s brakesystem. This available power outputto the trailer brakes can be adjustedto a wide range of traileringsituations.

The ITBC system is integrated withthe vehicle’s brake, antilock brake,and StabiliTrak (if equipped)systems. In trailering conditions thatcause the vehicle’s antilock brake orStabiliTrak systems to activate,power sent to the trailer's brakes willbe automatically adjusted tominimize trailer wheel lock-up. Thisdoes not imply that the trailer hasStabiliTrak.

Non-hybrid vehicles with StabiliTrakhave a Trailer Sway Control (TSC)feature. See Trailer Sway Control(TSC) on page 9‑118.

Trailer Gain Adjustment Procedure

Trailer Gain should be set for aspecific trailering condition and mustbe adjusted any time vehicleloading, trailer loading, or roadsurface conditions change.

Setting the Trailer Gain properly isneeded for the best trailer stoppingperformance. A trailer that isover-gained may result in lockedtrailer brakes. A trailer that isunder-gained may result in notenough trailer braking. Both of theseconditions may result in poorerstopping and stability of the vehicleand trailer.

Use the following procedure tocorrectly adjust Trailer Gain for eachtowing condition:

1. Make sure the trailer brakes arein proper working condition.

2. Connect a properly loaded trailerto the vehicle and make allnecessary mechanical andelectrical connections. SeeVehicle Load Limits onpage 9‑17 for more information.

3. After the electrical connection ismade to a trailer equipped withelectric brakes:. A TRAILER CONNECTED

message will be brieflydisplayed on the DIC.

. The Trailer Brake DisplayPage will appear on theDIC showing TRAILERGAIN and TRAILEROUTPUT.

. In the Trailer Output displayon the DIC, “- - - - - -” willdisappear if there is noerror present. Connecting atrailer without electricbrakes will not clear the sixdashed lines.

4. Adjust the Trailer Gain by usingthe gain adjustment (+ / -)buttons on the Trailer BrakeControl Panel.

5. Drive the vehicle with the trailerattached on a level road surfacerepresentative of the towingcondition and free of traffic atabout 32 to 40 km/h (20 to25 mph) and fully apply theManual Trailer Brake ApplyLever.

Adjusting trailer gain at speedslower than 32 to 40 km/h (20 to25 mph) may result in anincorrect gain setting.

Add-On ElectricalEquipmentNotice: Do not add anythingelectrical to the vehicle unlessyou check with your dealer first.Some electrical equipment candamage the vehicle and thedamage would not be covered bythe vehicle's warranty. Someadd-on electrical equipment cankeep other components fromworking as they should.

Add-on equipment can drain thevehicle's 12‐volt battery, even if thevehicle is not operating.

The vehicle has an airbag system.Before attempting to add anythingelectrical to the vehicle, seeServicing the Airbag-EquippedVehicle on page 3‑42 and AddingEquipment to the Airbag-EquippedVehicle on page 3‑43.

Adding a Snow Plow orSimilar EquipmentBefore installing a snow plow on thevehicle, here are some things youneed to know:

Notice: If the vehicle does nothave the snow plow preppackage, adding a plow candamage the vehicle, and therepairs would not be covered bywarranty. Unless the vehicle wasbuilt to carry a snow plow, do notadd one to the vehicle. If thevehicle has the snow plow preppackage, called RPO VYU, thenthe payload the vehicle can carrywill be reduced when a snowplow is installed. The vehicle canbe damaged if either the front orrear axle ratings or the GrossVehicle Weight (GVW) areexceeded.

Some vehicles are built with aspecial snow plow prep package,called RPO VYU. If the vehicle hasthis option, you can add a plow to it,provided certain weights, such asthe weights on the vehicle'saxles and the Gross VehicleWeight (GVW), are not exceeded.

The plow the vehicle can carrydepends on many things, such as:. The options the vehicle came

with, and the weight of thoseoptions.

. The weight and number ofpassengers intended to becarried.

. The weight of items added to thevehicle, like a tool box ortruck cap.

. The total weight of anyadditional cargo intended to becarried.

Say, for example, you have a 318 kg(700 lb) snow plow. The total weightof all occupants and cargo insidethe cab should not exceed 135 kg(300 lb). This means that you mayonly be able to carry one passenger.But, even this may be too much ifthere is other equipment alreadyadding to the weight of the vehicle.

Here are some guidelines for safelycarrying a snow plow on the vehicle:. Make sure the weight on the

front and rear axles does notexceed the axle rating for each.

. For the front axle, if more cargoor passengers must be carried,appropriate counter ballast mustbe installed rear of the rear axle.Counter ballast must be properlysecured so it will not moveduring driving.

. Follow the snow plowmanufacturer'srecommendations regardingrear ballast. Rear ballastmay be required to ensure aproper front and rear weightdistribution ratio, even thoughthe actual weight at the frontaxle may be less than the frontaxle rating.

. The snow plow manufacturer orinstaller can assist you indetermining the amount of rearballast required, to help makesure the snowplow/vehiclecombination does not exceedthe GVW rating, the front andrear axle ratings, and the frontand rear weight distribution ratio.

. The total vehicle must notexceed the GVW rating.

Front axle reserve capacity is thedifference between the Gross AxleWeight Rating (GAWR) and the frontaxle weight of the vehicle with fullfuel and passengers. Basically, it isthe amount of weight that can beadded to the front axle beforereaching the front GAWR.

The front axle reserve capacity forthe vehicle can be found in thelower right corner of theCertification/Tire label, asshown.

In order to calculate the amount ofweight any front accessory, such asa snow plow, is adding to the frontaxle, use the following formula:

(W x (A +W.B.)) /W.B.= Weight theaccessory is adding to thefront axle.

Where:W = Weight of added accessoryA = Distance that the accessoryis in front of the front axleW.B. = Vehicle Wheelbase

For example, adding a 318 kg(700 lb) snow plow actually addsmore than 318 kg (700 lb) to thefront axle. Using the formula, if thesnow plow is 122 cm (4 ft) in front ofthe front axle and the wheel base is305 cm (10 ft), then:

W = 318 kg (700 lb)A = 122 cm (4 ft)W.B. = 305 cm (10 ft)

(W x (A +W.B.))/W.B. =(318 x (122 + 305))/305 = 445 kg(980 lbs)

So, if the front axle reserve capacityis more than 445 kg (980 lbs), thesnow plow could be added withoutexceeding the front GAWR.

9-122 Driving and Operating

Heavier equipment can be added onthe front of the vehicle if it iscompensated for by carrying fewerpassengers, less cargo, or bypositioning cargo toward the rear.This has the effect of reducing theload on the front. However, the frontGAWR, rear GAWR, and the GrossVehicle Weight Rating (GVWR) mustnever be exceeded.

{ WARNING

On some vehicles that havecertain front mounted equipment,such as a snow plow, it may bepossible to load the front axle tothe front gross axle weight rating(GAWR) but not have enoughweight on the rear axle to haveproper braking performance. If thebrakes cannot work properly, youcould have a crash. To help thebrakes work properly when asnow plow is installed, alwaysfollow the snow plow

(Continued)

WARNING (Continued)

manufacturer or installer'srecommendation for rear ballastto ensure a proper front and rearweight distribution ratio, eventhough the actual front weightmay be less than the frontGAWR, and the total vehicleweight is less than the grossvehicle weight rating (GVWR).Maintaining a proper front andrear weight distribution ratio isnecessary to provide properbraking performance.

Total vehicle reserve capacity is thedifference between the GVWR andthe weight of the truck with full fueland passengers. It is the amount ofweight that can be added to thevehicle before reaching the GVWR.Keep in mind that reserve capacitynumbers are intended as a guidewhen selecting the amount ofequipment or cargo the truck cancarry. If unsure of the vehicle's front,rear, or total weight, go to a weighstation and weigh the vehicle. Yourdealer can also help with this.

The total vehicle reserve capacityfor the vehicle can be found in thelower right corner of theCertification/Tire label as shownpreviously.

10-8 Vehicle Care

Checking Engine Oil

It is a good idea to check the engineoil level at each fuel fill. In order toget an accurate reading, the vehiclemust be on level ground. Theengine oil dipstick handle is a yellowloop. See Engine CompartmentOverview on page 10‑6 for thelocation of the engine oil dipstick.

Obtaining an accurate oil levelreading is essential:

1. If the engine has been runningrecently, turn off the engine andallow several minutes for the oilto drain back into the oil pan.Checking the oil level too soonafter engine shutoff will notprovide an accurate oil levelreading.

2. Pull out the dipstick and clean itwith a paper towel or cloth, thenpush it back in all the way.Remove it again, keeping the tipdown, and check the level.

When to Add Engine Oil

If the oil is below the cross-hatchedarea at the tip of the dipstick, add1 L (1 qt) of the recommended oiland then recheck the level. See“Selecting the Right Engine Oil” inthis section for an explanation ofwhat kind of oil to use. For engineoil crankcase capacity, seeCapacities and Specifications onpage 12‑2.

Notice: Do not add too much oil.Oil levels above or below theacceptable operating rangeshown on the dipstick are harmfulto the engine. If you find that youhave an oil level above theoperating range, i.e., the enginehas so much oil that the oil levelgets above the cross-hatchedarea that shows the properoperating range, the engine couldbe damaged. You should drainout the excess oil or limit drivingof the vehicle and seek a serviceprofessional to remove theexcess amount of oil.

See Engine Compartment Overviewon page 10‑6 for the location of theengine oil fill cap.

Add enough oil to put the levelsomewhere in the proper operatingrange. Push the dipstick all the wayback in when through.

Vehicle Care 10-9

Selecting the Right Engine Oil

Selecting the right engine oildepends on both the proper oilspecification and viscosity grade.See Recommended Fluids andLubricants on page 11‑13.

Specification

Use and ask for licensed engine oilswith the dexos1™ approvedcertification mark. Engine oilsmeeting the requirements for thevehicle should have the dexos™1approved certification mark. Thiscertification mark indicates that theoil has been approved to the dexos1specification.

Notice: Failure to use therecommended engine oil orequivalent can result in enginedamage not covered by thevehicle warranty. Check with yourdealer or service provider onwhether the oil is approved to thedexos1 specification.

Viscosity Grade

SAE 5W‐30 is the best viscositygrade for the vehicle. Do not useother viscosity grade oils such asSAE 10W‐30, 10W‐40, or 20W‐50.

If in an area of extreme cold, wherethe temperature falls below −20°F(−29°C), an SAE 0W‐30 oil shouldbe used. An oil of this viscositygrade will provide easier coldstarting for the engine at extremelylow temperatures. When selectingan oil of the appropriate viscositygrade, always select an oil thatmeets the dexos1 specification orequivalent. See “Specification” formore information.

Engine Oil Additives/EngineOil Flushes

Do not add anything to the oil. Therecommended oils with the dexosspecification and displaying thedexos certification mark are all thatis needed for good performance andengine protection.

Engine oil system flushes are notrecommended and could causeengine damage not covered by thevehicle warranty.

What to Do with Used Oil

Used engine oil contains certainelements that can be unhealthy foryour skin and could even causecancer. Do not let used oil stay onyour skin for very long. Clean yourskin and nails with soap and water,or a good hand cleaner. Wash orproperly dispose of clothing or ragscontaining used engine oil. See themanufacturer's warnings about theuse and disposal of oil products.

Used oil can be a threat to theenvironment. If you change yourown oil, be sure to drain all the oilfrom the filter before disposal. Neverdispose of oil by putting it in thetrash or pouring it on the ground,into sewers, or into streams orbodies of water. Recycle it by takingit to a place that collects used oil.

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer systemthat indicates when to change theengine oil and filter. This is basedon a combination of factors whichinclude engine revolutions, enginetemperature, and miles driven.Based on driving conditions, themileage at which an oil change isindicated can vary considerably. Forthe oil life system to work properly,the system must be reset every timethe oil is changed.

On some vehicles, when the systemhas calculated that oil life has beendiminished, a CHANGE ENGINEOIL SOON message comes on toindicate that an oil change isnecessary. See Engine OilMessages on page 5‑46. Changethe oil as soon as possible withinthe next 1 000 km (600mi). It ispossible that, if driving under the

best conditions, the oil life systemmight indicate that an oil change isnot necessary for up to a year. Theengine oil and filter must bechanged at least once a year and,at this time, the system must bereset. For vehicles without theCHANGE ENGINE OIL SOONmessage, an oil changeis needed when the OIL LIFEREMAINING percentage is near0%. Your dealer has trained servicepeople who will perform this workand reset the system. It is alsoimportant to check the oil regularlyover the course of an oil draininterval and keep it at the properlevel.

If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 mi)since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.

1. Display the OIL LIFEREMAINING on the DIC. If thevehicle does not have DICbuttons, the vehicle must be inP (Park) to access this display.See Driver Information Center(DIC) on page 5‑33.

2. Press and hold the SET/RESETbutton on the DIC, or the tripodometer reset stem if thevehicle does not have DICbuttons, for more thanfive seconds. The oil life willchange to 100%.

On all vehicles, the Engine Oil LifeSystem can be reset as follows:

1. Turn the ignition to ON/RUN withthe engine off.

2. Fully press the accelerator pedalslowly three times withinfive seconds.

3. Display the OIL LIFEREMAINING on the DIC. If thedisplay shows 100%, the systemis reset. See Driver InformationCenter (DIC) on page 5‑33.

If the vehicle has a CHANGEENGINE OIL SOON message and itcomes back on when the vehicle isstarted and/or the OIL LIFEREMAINING is near 0%, the engineoil life system has not been reset.Repeat the procedure.

How to Check AutomaticTransmission Fluid

Because this operation can be alittle difficult, it may be best to havethis done at the dealer servicedepartment.

If not taken to the dealer, be sure tofollow all the instructions here or afalse reading on the dipstick couldresult.

Notice: Too much or toolittle fluid can damage thetransmission. Too much canmean that some of the fluid couldcome out and fall on hot engineparts or exhaust system parts,starting a fire. Too little fluidcould cause the transmission tooverheat. Be sure to get anaccurate reading if checking thetransmission fluid.

Wait at least 30 minutes beforechecking the transmission fluid levelif you have been driving:. When outside temperatures are

above 32°C (90°F).. At high speed for quite a while.. In heavy traffic— especially in

hot weather.. While pulling a trailer.

To get the right reading, the fluidshould be at normal operatingtemperature, which is 82°C to 93°C(180°F to 200°F).

Get the vehicle warmed up bydriving about 24 km (15 miles) whenoutside temperatures are above10°C (50°F). If it is colder than 10°C(50°F), drive the vehicle in 3 (Third)until the engine temperature gaugemoves and then remains steady for10 minutes.

A cold fluid check can be madeafter the vehicle has been sitting foreight hours or more with the engineoff, but this is used only as areference. Let the engine runat idle for five minutes if outsidetemperatures are 10°C (50°F) ormore. If it is colder than 10°C(50°F), the engine may have to idlelonger. Should the fluid level be lowduring this cold check, the fluid mustbe checked when hot before addingfluid. Checking the fluid hot will giveyou a more accurate reading of thefluid level.

Checking the Fluid Level

Prepare the vehicle as follows:

1. Park the vehicle on a levelplace. Keep the engine running.

2. With the parking brake applied,place the shift lever in P (Park).

3. With your foot on the brakepedal, move the shift leverthrough each gear range,pausing for about three secondsin each range. Then, position theshift lever in P (Park).

4. Let the engine run at idle forthree minutes or more.

Then, without shutting off theengine, follow these steps:

1. Locate the transmission dipstickhandle with this graphic which islocated at the rear of the enginecompartment, on the passengerside of the vehicle.

See Engine CompartmentOverview on page 10‑6 for moreinformation on location.

2. Flip the handle up, then pull outthe dipstick and wipe it with aclean rag or paper towel.

3. Push it back in all the way, waitthree seconds and then pull itback out again.

4. Check both sides of the dipstick,and read the lower level. Thefluid level must be in the COLDarea, below the cross-hatchedarea, for a cold check or in theHOT or cross-hatched area for ahot check. Be sure to keep thedipstick pointed down to get anaccurate reading.

5. If the fluid level is in theacceptable range, push thedipstick back in all the way; thenflip the handle down to lock thedipstick in place.

Consistency of Readings

Always check the fluid level at leasttwice using the procedure describedpreviously. Consistency (repeatablereadings) is important to maintainingproper fluid level. If readings are stillinconsistent, contact the dealer.

How to Add AutomaticTransmission Fluid

Refer to Recommended Fluids andLubricants on page 11‑13 todetermine what kind of transmissionfluid to use.

Using a funnel, add fluid down thetransmission dipstick tube only afterchecking the transmission fluidwhile it is hot. A cold check is usedonly as a reference. If the fluid levelis low, add only enough of theproper fluid to bring the level up tothe HOT area for a hot check.It does not take much fluid,generally less than 0.5 Liter (1 Pint).Do not overfill.

Notice: Use of the incorrectautomatic transmission fluid maydamage the vehicle, and thedamages may not be covered bythe vehicle warranty. Always usethe automatic transmission fluidlisted in Recommended Fluidsand Lubricants on page 11‑13.. After adding fluid, recheck the

fluid level as described under“How to Check AutomaticTransmission Fluid,” earlier inthis section.

. When the correct fluid level isobtained, push the dipstick backin all the way; then flip thehandle down to lock the dipstickin place.

How to Add Coolant to theCoolant Surge Tank forGasoline Engines

If the vehicle has a diesel engine,see “Cooling System” in theDuramax Diesel Supplement for theproper coolant fill procedure.

{ WARNING

You can be burned if you spillcoolant on hot engine parts.Coolant contains ethylene glycoland it will burn if the engine partsare hot enough. Do not spillcoolant on a hot engine.

Notice: This vehicle has aspecific coolant fill procedure.Failure to follow this procedurecould cause the engine tooverheat and be severelydamaged.

{ WARNING

An electric engine cooling fanunder the hood can start up evenwhen the engine is not runningand can cause injury. Keephands, clothing, and tools awayfrom any underhood electric fan.

{ WARNING

Steam and scalding liquids from ahot cooling system can blow outand burn you badly. They areunder pressure, and if you turnthe coolant surge tank pressurecap— even a little— they cancome out at high speed. Neverturn the cap when the coolingsystem, including the coolantsurge tank pressure cap, is hot.Wait for the cooling system andcoolant surge tank pressure capto cool if you ever have to turnthe pressure cap.

If no coolant is visible in the surgetank, add coolant as follows:

1. Remove the coolant surge tankpressure cap when the coolingsystem, including the coolantsurge tank pressure cap andupper radiator hose, is nolonger hot.

Turn the pressure cap slowlycounterclockwise about one fullturn. If a hiss is heard, wait forthat to stop. A hiss means thereis still some pressure left.

2. Keep turning the pressure capslowly, and remove it.

The ENGINE OVERHEATEDSTOP ENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage, along with a low coolantcondition, can indicate a seriousproblem.

If there is an engine overheatwarning, but no steam is seen orheard, the problem may not be tooserious. Sometimes the engine canget a little too hot when the vehicle:. Climbs a long hill on a hot day. Stops after high-speed driving. Idles for long periods in traffic. Tows a trailer; see Trailer Towing

on page 9‑90.

If the ENGINE OVERHEATEDSTOP ENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage appears with no sign ofsteam, try this for a minute or so:

1. Turn the air conditioning off.

2. Turn the heater on to the highesttemperature and to the highestfan speed. Open the windows asnecessary.

3. If stopped in a traffic jam, applythe brake, shift to N (Neutral);otherwise, shift to the highestgear while driving—D (Drive) or3 (Third).

If the temperature overheat gaugeis no longer in the overheat zone oran overheat warning no longerdisplays, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safevehicle distance from the vehicle infront. If the warning does not comeback on, continue to drive normally.

If the warning continues, pull over,stop, and park the vehicleright away.

Overheated EngineProtectionOperating ModeIf an overheated engine conditionexists and the ENGINE POWER ISREDUCED message displays, anoverheat protection mode whichalternates firing groups of cylindershelps to prevent engine damage. Inthis mode, a loss in power andengine performance will be noticed.This operating mode allows thevehicle to be driven to a safe placein an emergency. Drivingextended km (mi) and/or towing atrailer in the overheat protectionmode should be avoided.

Notice: After driving in theoverheated engine protectionoperating mode, to avoid enginedamage, allow the engine to coolbefore attempting any repair. Theengine oil will be severelydegraded. Repair the cause ofcoolant loss, change the oil andreset the oil life system. SeeEngine Oil on page 10‑7.

Engine FanIf the vehicle has a clutched enginecooling fan, when the clutch isengaged, the fan spins faster toprovide more air to cool the engine.In most everyday driving conditions,the fan is spinning slower and theclutch is not fully engaged. Thisimproves fuel economy and reducesfan noise. Under heavy vehicleloading, trailer towing, and/or highoutside temperatures, the fan speedincreases as the clutch more fullyengages, so an increase in fannoise may be heard. This is normaland should not be mistaken as thetransmission slipping or makingextra shifts. It is merely the coolingsystem functioning properly. The fanwill slow down when additionalcooling is not required and theclutch disengages.

This fan noise may also be heardwhen starting the engine. It will goaway as the fan clutch partiallydisengages.

If the vehicle has electric coolingfans, the fans may be heardspinning at low speed during mosteveryday driving. The fans may turnoff if no cooling is required. Underheavy vehicle loading, trailer towing,high outside temperatures,or operation of the air conditioningsystem, the fans may change tohigh speed and an increase in fannoise may be heard. This is normaland indicates that the coolingsystem is functioning properly. Thefans will change to low speed whenadditional cooling is no longerrequired.

Power Steering Fluid

See Engine Compartment Overviewon page 10‑6 for reservoir location.

When to Check Power SteeringFluid

It is not necessary to regularlycheck power steering fluid unlessthere is a leak suspected in thesystem or an unusual noise isheard. A fluid loss in this systemcould indicate a problem. Have thesystem inspected and repaired.

How to Check Power SteeringFluid

Notice: Extremely small amountsof contamination can causesteering system damage andcause it to not work properly. Donot allow contaminants to contactthe fluid side of the reservoir cap/dipstick or to enter the reservoir.

To check the power steering fluid:

1. Turn the key off and let theengine compartment cool down.

2. Wipe the cap and the top of thereservoir clean.

3. Unscrew the cap and wipe thedipstick with a clean rag.

4. Replace the cap and completelytighten it.

5. Remove the cap again and lookat the fluid level on the dipstick.

Washer Fluid

What to Use

When windshield washer fluid needsto be added, be sure to read themanufacturer's instructions beforeuse. Use a fluid that has sufficientprotection against freezing in anarea where the temperature may fallbelow freezing.

Adding Washer Fluid

The vehicle has a low washer fluidmessage on the DIC that comes onwhen the washer fluid is low. Themessage is displayed for15 seconds at the start of eachignition cycle. When the WASHERFLUID LOW ADD FLUID messagedisplays, washer fluid will need tobe added to the windshield washerfluid reservoir.

Open the cap with the washersymbol on it. Add washer fluid untilthe tank is full. See EngineCompartment Overview onpage 10‑6 for reservoir location.

Notice. When using concentratedwasher fluid, follow themanufacturer's instructionsfor adding water.

. Do not mix water withready-to-use washer fluid.Water can cause the solutionto freeze and damage thewasher fluid tank and otherparts of the washer system.

. Fill the washer fluid tank onlythree-quarters full when it isvery cold. This allows forfluid expansion if freezingoccurs, which coulddamage the tank if it iscompletely full.

. Do not use engine coolant(antifreeze) in the windshieldwasher. It can damage thewindshield washer systemand paint.

BrakesThis vehicle has front disc brakesand could have rear drum brakes orrear disc brakes.

Disc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go or beheard all the time the vehicle ismoving, except when applying thebrake pedal firmly.

{ WARNING

The brake wear warning soundmeans that soon the brakes willnot work well. That could lead toa crash. When the brake wearwarning sound is heard, have thevehicle serviced.

Notice: Continuing to drive withworn-out brake pads could resultin costly brake repair.

Some driving conditions or climatescan cause a brake squeal when thebrakes are first applied or lightlyapplied. This does not meansomething is wrong with the brakes.

Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear andevenly tighten wheel nuts in theproper sequence to torquespecifications in Capacities andSpecifications on page 12‑2.

If the vehicle has rear drum brakes,they do not have wear indicators,but if a rear brake rubbing noise isheard, have the rear brake liningsinspected immediately. Rear brakedrums should be removed andinspected each time the tires areremoved for rotation or changing.

Drum brakes have an inspectionhole to inspect lining wear duringscheduled maintenance. When thefront brake pads are replaced, havethe rear brakes inspected, too.

Brake linings should always bereplaced as complete axle sets.

Brake Pedal Travel

See your dealer if the brake pedaldoes not return to normal height,or if there is a rapid increase inpedal travel. This could be a signthat brake service might berequired.

Brake Adjustment

Every time the brakes are applied,with or without the vehicle moving,the brakes adjust for wear.

Replacing Brake System Parts

The braking system on a vehicle iscomplex. Its many parts have to beof top quality and work well togetherif the vehicle is to have really goodbraking. The vehicle was designedand tested with top-quality brakeparts. When parts of the brakingsystem are replaced, be sure to getnew, approved replacement parts.If this is not done, the brakes mightnot work properly. For example,installing disc brake pads that arewrong for the vehicle, can changethe balance between the front andrear brakes— for the worse. Thebraking performance expected canchange in many other ways if thewrong replacement brake parts areinstalled.

Brake Fluid

The brake master cylinder reservoiris filled with DOT 3 brake fluid. SeeEngine Compartment Overview onpage 10‑6 for the location of thereservoir.

There are only two reasons why thebrake fluid level in the reservoirmight go down:. The brake fluid level goes down

because of normal brake liningwear. When new linings areinstalled, the fluid level goesback up.

. A fluid leak in the brakehydraulic system can also causea low fluid level. Have the brakehydraulic system fixed, since aleak means that sooner or laterthe brakes will not work well.

Do not top off the brake fluid.Adding fluid does not correct a leak.If fluid is added when the linings areworn, there will be too much fluidwhen new brake linings areinstalled. Add or remove brake fluid,as necessary, only when work isdone on the brake hydraulic system.

{ WARNING

If too much brake fluid is added, itcan spill on the engine and burn,if the engine is hot enough. Youor others could be burned, andthe vehicle could be damaged.Add brake fluid only when work isdone on the brake hydraulicsystem. See “Checking BrakeFluid” in this section.

When the brake fluid falls to a lowlevel, the brake warning light comeson. See Brake System WarningLight on page 5‑27.

10-32 Vehicle Care

Refer to the Maintenance Scheduleto determine when to check thebrake fluid. See MaintenanceSchedule on page 11‑3.

Checking Brake Fluid

Check brake fluid by looking at thebrake fluid reservoir. See EngineCompartment Overview onpage 10‑6.

The fluid level should be aboveMIN. If it is not, have the brakehydraulic system checked to see ifthere is a leak.

After work is done on the brakehydraulic system, make sure thelevel is above the MIN but not overthe MAX mark.

What to Add

Use only new DOT 3 brake fluidfrom a sealed container. SeeRecommended Fluids andLubricants on page 11‑13.

Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it. Thishelps keep dirt from entering thereservoir.

{ WARNING

With the wrong kind of fluid in thebrake hydraulic system, thebrakes might not work well. Thiscould cause a crash. Always usethe proper brake fluid.

Notice. Using the wrong fluid canbadly damage brakehydraulic system parts. Forexample, just a few drops ofmineral-based oil, such asengine oil, in the brakehydraulic system candamage brake hydraulicsystem parts so badly thatthey will have to be replaced.Do not let someone put inthe wrong kind of fluid.

. If brake fluid is spilled on thevehicle's painted surfaces,the paint finish can bedamaged. Be careful not tospill brake fluid on thevehicle. If you do, wash it offimmediately.

It is not necessary to regularlycheck rear axle fluid unless a leak issuspected or an unusual noise isheard. A fluid loss could indicate aproblem. Have it inspected andrepaired.

All axle assemblies are filled byvolume of fluid during production.They are not filled to reach a certainlevel. When checking the fluid levelon any axle, variations in thereadings can be caused by factoryfill differences between the minimumand the maximum fluid volume.Also, if a vehicle has just beendriven before checking the fluidlevel, it may appear lower thannormal because fluid has traveledout along the axle tubes and hasnot drained back to the sump area.Therefore, a reading takenfive minutes after the vehicle hasbeen driven will appear to have alower fluid level than a vehicle thathas been stationary for an hour ortwo. Remember that the rear axleassembly must be supported to geta true reading.

Electrical System

Electrical SystemOverloadThe vehicle has fuses and circuitbreakers to protect against anelectrical system overload.

When the current electrical load istoo heavy, the circuit breaker opensand closes, protecting the circuituntil the current load returns tonormal or the problem is fixed. Thisgreatly reduces the chance of circuitoverload and fire caused byelectrical problems.

Fuses and circuit breakers protectpower devices in the vehicle.

Replace a bad fuse with a new oneof the identical size and rating.

If there is a problem on the road anda fuse needs to be replaced, thesame amperage fuse can beborrowed. Choose some feature ofthe vehicle that is not needed to useand replace it as soon as possible.

Vehicle Care 10-49

Headlamp Wiring

An electrical overload may causethe lamps to go on and off, or insome cases to remain off. Have theheadlamp wiring checked right awayif the lamps go on and off orremain off.

Windshield Wipers

If the wiper motor overheats due toheavy snow or ice, the windshieldwipers will stop until the motor coolsand will then restart.

Although the circuit is protectedfrom electrical overload, overloaddue to heavy snow or ice maycause wiper linkage damage.Always clear ice and heavy snowfrom the windshield before using thewindshield wipers.

If the overload is caused by anelectrical problem and not snow orice, be sure to get it fixed.

Fuses and CircuitBreakersIf the vehicle is a hybrid, see thehybrid supplement for moreinformation.

The wiring circuits in the vehicle areprotected from short circuits by acombination of fuses, circuitbreakers and fusible thermal links.This greatly reduces the chance offires caused by electrical problems.

Look at the silver-colored bandinside the fuse. If the band is brokenor melted, replace the fuse. Be sureyou replace a bad fuse with a newone of the identical size and rating.

If you ever have a problem on theroad and don't have a spare fuse,you can borrow one that has thesame amperage. Just pick somefeature of your vehicle that you canget along without– like the radio oraccessory power outlet– and use itsfuse, if it is the correct amperage.Replace it as soon as you can.

TiresEvery new GM vehicle hashigh-quality tires made by aleading tire manufacturer. Seethe warranty manual forinformation regarding the tirewarranty and where to getservice. For additionalinformation refer to the tiremanufacturer.

{ WARNING

. Poorly maintained andimproperly used tires aredangerous.

. Overloading the tires cancause overheating as a resultof too much flexing. Therecould be a blowout and aserious crash. See VehicleLoad Limits on page 9‑17.

(Continued)

WARNING (Continued)

. Underinflated tires pose thesame danger as overloadedtires. The resulting crashcould cause serious injury.Check all tires frequently tomaintain the recommendedpressure. Tire pressureshould be checked when thetires are cold.

. Overinflated tires are morelikely to be cut, punctured,or broken by a suddenimpact— such as whenhitting a pothole. Keep tires atthe recommended pressure.

. Worn or old tires can cause acrash. If the tread is badlyworn, replace them.

. Replace any tires that havebeen damaged by impactswith potholes, curbs, etc.

(Continued)

WARNING (Continued)

. Improperly repaired tires cancause a crash. Only thedealer or an authorized tireservice center should repair,replace, dismount, and mountthe tires.

. Do not spin the tires inexcess of 56 km/h (35 mph)on slippery surfaces such assnow, mud, ice, etc.Excessive spinning maycause the tires to explode.

For additional informationregarding how much weight thevehicle can carry, and anexample of the Tire and LoadingInformation label, see VehicleLoad Limits on page 9‑17. Howthe vehicle is loaded affectsvehicle handling and ridecomfort. Never load the vehiclewith more weight than it wasdesigned to carry.

When to Check

Check the tires once a monthor more.

Do not forget the spare tire,if the vehicle has one. SeeFull-Size Spare Tire onpage 10‑95 for additionalinformation.

How to Check

Use a good quality pocket-typegauge to check tire pressure.Proper tire inflation cannot bedetermined by looking at the tire.

Check the tire inflation pressurewhen the tires are cold, meaningthe vehicle has not been drivenfor at least three hours or nomore than 1.6 km (1 mi).

Remove the valve cap from thetire valve stem. Press the tiregauge firmly onto the valve toget a pressure measurement.If the cold tire inflation pressurematches the recommendedpressure on the Tire andLoading Information label, nofurther adjustment is necessary.If the inflation pressure is low,add air until the recommendedpressure is reached. If theinflation pressure is high, presson the metal stem in the centerof the tire valve to release air.

Re-check the tire pressure withthe tire gauge.

Return the valve caps on thevalve stems to prevent leaksand keep out dirt and moisture.

Tire Pressure forHigh-Speed Operation

{ WARNING

Driving at high speeds, 160 km/h(100mph) or higher, puts anadditional strain on tires.Sustained high-speed drivingcauses excessive heat buildupand can cause sudden tire failure.You could have a crash and youor others could be killed. Somehigh-speed rated tires requireinflation pressure adjustment forhigh-speed operation. Whenspeed limits and road conditionsare such that a vehicle can bedriven at high speeds, make surethe tires are rated for high-speedoperation, in excellent condition,and set to the correct cold tireinflation pressure for thevehicle load.

Page 491: 2012 Chevrolet Silverado Owner Manual M - General Motors · Chevrolet Silverado Owner Manual - 2012 Black plate (3,1) Introduction iii The names, logos, emblems, slogans, vehicle

Black plate (67,1)Chevrolet Silverado Owner Manual - 2012

Vehicle Care 10-67

Vehicles with P265/70R17 or P275/55R20 size tires require inflationpressure adjustment when drivingthe vehicle at speeds of 160 km/h(100 mph) or higher. Set the cold tireinflation pressure to 20 kPa (3 psi)above the recommended cold tirepressure shown on the Tire andLoading Information label.

Return the tires to therecommended cold tire inflationpressure when high-speed drivinghas ended. See Vehicle Load Limitson page 9‑17 and Tire Pressure onpage 10‑65.

Tire Pressure MonitorSystemThe Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitorthe air pressure in your tires andtransmit tire pressure readings to areceiver located in the vehicle.

Each tire, including the spare(if provided), should be checkedmonthly when cold and inflated tothe inflation pressure recommendedby the vehicle manufacturer on thevehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)

As an added safety feature, yourvehicle has been equipped with atire pressure monitoring system(TPMS) that illuminates a low tirepressure telltale when one or moreof your tires is significantly under‐inflated.

Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving on asignificantly under‐inflated tirecauses the tire to overheat and can

lead to tire failure. Under‐inflationalso reduces fuel efficiency and tiretread life, and may affect thevehicle's handling and stoppingability.

Please note that the TPMS isnot a substitute for proper tiremaintenance, and it is the driver'sresponsibility to maintain correct tirepressure, even if under‐inflation hasnot reached the level to triggerillumination of the TPMS low tirepressure telltale.

Your vehicle has also beenequipped with a TPMS malfunctionindicator to indicate when thesystem is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated.This sequence will continue uponsubsequent vehicle start‐ups aslong as the malfunction exists.

10-68 Vehicle Care

When the malfunction indicator isilluminated, the system may not beable to detect or signal low tirepressure as intended. TPMSmalfunctions may occur for a varietyof reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.

See Tire Pressure MonitorOperation on page 10‑68 foradditional information.

See Radio Frequency Statement onpage 13‑23 for informationregarding Part 15 of the FederalCommunications Commission (FCC)Rules and with Industry CanadaStandards RSS-GEN/210/220/310.

Tire Pressure MonitorOperationThis vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, excluding the spare tireand wheel assembly. The TPMSsensors monitor the air pressure inthe tires and transmit the tirepressure readings to a receiverlocated in the vehicle.

When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning lightlocated on the instrument cluster.If the warning light comes on, stopas soon as possible and inflate thetires to the recommended pressureshown on the Tire and LoadingInformation label. See Vehicle LoadLimits on page 9‑17.

A message to check the pressure ina specific tire displays in the DriverInformation Center (DIC). The lowtire pressure warning light and theDIC warning message come on ateach ignition cycle until the tires areinflated to the correct inflationpressure. If the vehicle has DICbuttons, tire pressure levels can beviewed. For additional informationand details about the DIC operation

and displays, see Driver InformationCenter (DIC) on page 5‑33 and TireMessages on page 5‑50.

The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven. Thiscould be an early indicator that theair pressure is getting low andneeds to be inflated to the properpressure.

A Tire and Loading Information labelshows the size of the originalequipment tires and the correctinflation pressure for the tires whenthey are cold. See Vehicle LoadLimits on page 9‑17, for an exampleof the Tire and Loading Informationlabel and its location. Also see TirePressure on page 10‑65.

The TPMS can warn about a lowtire pressure condition but itdoes not replace normal tiremaintenance. See Tire Inspectionon page 10‑71, Tire Rotation onpage 10‑72 and Tires onpage 10‑57.

Notice: Tire sealant materials arenot all the same. A non-approvedtire sealant could damage theTPMS sensors. TPMS sensordamage caused by using anincorrect tire sealant is notcovered by the vehiclewarranty. Always use only theGM-approved tire sealantavailable through your dealer orincluded in the vehicle.

TPMS Malfunction Light andMessage

The TPMS will not function properlyif one or more of the TPMS sensorsare missing or inoperable. When thesystem detects a malfunction, thelow tire pressure warning lightflashes for about one minute andthen stays on for the remainder ofthe ignition cycle. A DIC warningmessage also displays. Themalfunction light and DIC warningmessage come on at each ignition

cycle until the problem is corrected.Some of the conditions that cancause these to come on are:. One of the road tires has been

replaced with the spare tire. Thespare tire does not have aTPMS sensor. The malfunctionlight and the DIC messageshould go off after the road tireis replaced and the sensormatching process is performedsuccessfully. See "TPMS SensorMatching Process" later in thissection.

. The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires. Themalfunction light and the DICmessage should go off aftersuccessfully completing thesensor matching process. See"TPMS Sensor MatchingProcess" later in this section.

. One or more TPMS sensors aremissing or damaged. Themalfunction light and the DICmessage should go off when theTPMS sensors are installed andthe sensor matching process isperformed successfully. Seeyour dealer for service.

. Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommendedcould prevent the TPMS fromfunctioning properly. See BuyingNew Tires on page 10‑75.

. Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.

If the TPMS is not functioningproperly, it cannot detect or signal alow tire condition. See your dealerfor service if the TPMS malfunctionlight and DIC message come onand stay on.

TPMS Sensor MatchingProcess

Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thevehicle’s tires or replacing one ormore of the TPMS sensors. Also,the TPMS sensor matching processshould be performed after replacinga spare tire with a road tirecontaining the TPMS sensor. Themalfunction light and the DICmessage should go off at the nextignition cycle. The sensors arematched to the tire/wheel positions,using a TPMS relearn tool, in thefollowing order: driver side front tire,passenger side front tire, passengerside rear tire, and driver side rear.See your dealer for service or topurchase a relearn tool.

There are two minutes to match thefirst tire/wheel position, andfive minutes overall to match all fourtire/wheel positions. If it takeslonger, the matching process stopsand must be restarted.

The TPMS sensor matchingprocess is:

1. Set the parking brake.

2. Turn the ignition to ON/RUN withthe engine off.

3. Press the Remote Keyless Entry(RKE) transmitter's LOCK andUNLOCK buttons at the sametime for approximatelyfive seconds. The horn soundstwice to signal the receiver is inrelearn mode and TIRELEARNING ACTIVE messagedisplays on the DIC screen.

If the vehicle does not haveRKE, press the DriverInformation Center (DIC) vehicleinformation button until thePRESS V TO RELEARN TIREPOSITIONS message displays.The horn sounds twice to signalthe receiver is in relearn modeand TIRE LEARNING ACTIVEmessage displays on the DICscreen.

6. Proceed to the passenger sidefront tire, and repeat theprocedure in Step 5.

7. Proceed to the passenger siderear tire, and repeat theprocedure in Step 5.

8. Proceed to the driver side reartire, and repeat the procedure inStep 5. The horn sounds twotimes to indicate the sensoridentification code has beenmatched to the driver side reartire, and the TPMS sensormatching process is no longeractive. The TIRE LEARNINGACTIVE message on the DICdisplay screen goes off.

9. Turn the ignition switch toLOCK/OFF.

10. Set all four tires to therecommended air pressurelevel as indicated on the Tireand Loading Information label.

Tire InspectionWe recommend that the tires,including the spare tire, if thevehicle has one, be inspectedfor signs of wear or damage atleast once a month.

Replace the tire if:. The indicators at three or

more places around the tirecan be seen.

. There is cord or fabricshowing through the tire'srubber.

. The tread or sidewall iscracked, cut, or snaggeddeep enough to show cord orfabric.

. The tire has a bump, bulge,or split.

. The tire has a puncture, cut,or other damage that cannotbe repaired well because ofthe size or location of thedamage.

Tire RotationTires should be rotated every12 000 km (7,500 mi). SeeMaintenance Schedule onpage 11‑3.

Tires are rotated to achieve auniform wear for all tires. Thefirst rotation is the mostimportant.

Any time unusual wear isnoticed, rotate the tires as soonas possible and check the wheelalignment. Also check fordamaged tires or wheels. SeeWhen It Is Time for New Tireson page 10‑75 and WheelReplacement on page 10‑80.

If your vehicle has dual rearwheels, also see Dual TireRotation on page 10‑74.

Use this rotation pattern whenrotating the tires if the vehiclehas single rear wheels.

Use this rotation pattern whenrotating the tires if the vehiclehas dual rear wheels (exceptpolished forged aluminumwheels).

Vehicles with polished forgedaluminum dual wheels havethree unique wheels; a front, arear outer and a rear inner.These wheels cannot be rotatedto another position, however,they can be rotated from left toright to the same position.

Use this rotation pattern whenrotating the tires if the vehiclehas polished forged aluminumdual rear wheels.

The spare wheel can be used inany position and can be rotatedwith the rear inner wheels.

When installing dual wheels,check that the vent holes in theinner and outer wheels on eachside are lined up.

Adjust the front and rear tires tothe recommended inflationpressure on the Tire andLoading Information label afterthe tires have been rotated. SeeTire Pressure on page 10‑65and Vehicle Load Limits onpage 9‑17.

Check that all wheel nuts areproperly tightened. See“WheelNut Torque” under Capacitiesand Specifications onpage 12‑2.

{ WARNING

Rust or dirt on a wheel, or on theparts to which it is fastened, canmake wheel nuts become looseafter time. The wheel could comeoff and cause an accident. Whenchanging a wheel, remove anyrust or dirt from places where thewheel attaches to the vehicle. Inan emergency, a cloth or a papertowel can be used; however, usea scraper or wire brush later toremove all rust or dirt.

Lightly coat the center of thewheel hub with wheel bearinggrease after a wheel change ortire rotation to prevent corrosionor rust build-up. Do not getgrease on the flat wheelmounting surface or on thewheel nuts or bolts.

When It Is Time for NewTiresFactors, such as maintenance,temperatures, driving speeds,vehicle loading, and road conditionsaffect the wear rate of the tires.

Treadwear indicators are one way totell when it is time for new tires.Treadwear indicators appear whenthe tires have only 1.6 mm (1/16 in)or less of tread remaining. Somecommercial truck tires may not havetreadwear indicators. See Tire

Inspection on page 10‑72 and TireRotation on page 10‑72 foradditional information.

The rubber in tires ages over time.This also applies to the spare tire,if the vehicle has one, even if it isnever used. Multiple conditionsincluding temperatures, loadingconditions, and inflation pressuremaintenance affect how fast agingtakes place. Tires will typically needto be replaced due to wear beforethey may need to be replaced dueto age. Consult the tiremanufacturer for more informationon when tires should be replaced.

Vehicle Storage

Tires age when stored normallymounted on a parked vehicle. Parka vehicle that will be stored for atleast a month in a cool, dry, cleanarea away from direct sunlight toslow aging. This area should be freeof grease, gasoline or othersubstances that can deterioraterubber.

Parking for an extended period cancause flat spots on the tires thatmay result in vibrations whiledriving. When storing a vehicle forat least a month, remove the tires orraise the vehicle to reduce theweight from the tires.

Buying New TiresGM has developed and matchedspecific tires for the vehicle. Theoriginal equipment tires installedwere designed to meet GeneralMotors Tire Performance CriteriaSpecification (TPC Spec) systemrating. When replacement tires areneeded, GM strongly recommendsbuying tires with the same TPCSpec rating.

10-76 Vehicle Care

GM's exclusive TPC Spec systemconsiders over a dozen criticalspecifications that impact the overallperformance of the vehicle,including brake systemperformance, ride and handling,traction control, and tire pressuremonitoring performance. GM's TPCSpec number is molded onto thetire's sidewall near the tire size.If the tires have an all‐season treaddesign, the TPC Spec number willbe followed by MS for mud andsnow. See Tire Sidewall Labeling onpage 10‑58 for additionalinformation.

GM recommends replacing all thetires at the same time. Uniform treaddepth on all tires will help tomaintain the performance of thevehicle. Braking and handlingperformance may be adverselyaffected if all the tires are notreplaced at the same time. See TireInspection on page 10‑71 and TireRotation on page 10‑72 forinformation on proper tire rotation.

{ WARNING

Tires could explode duringimproper service. Attemptingto mount or dismount a tirecould cause injury or death.Only your dealer or authorizedtire service center shouldmount or dismount the tires.

{ WARNING

Mixing tires of different sizes,brands, or types may cause lossof control of the vehicle, resultingin a crash or other vehicledamage. Use the correct size,brand, and type of tires on allwheels.

This vehicle may have a differentsize spare than the road tiresoriginally installed on the vehicle.When new, the vehicle included a

If the vehicle tires must be replacedwith a tire that does not have a TPCSpec number, make sure they arethe same size, load range, speedrating, and construction (radial) asthe original tires.

Vehicles that have a tire pressuremonitoring system could give aninaccurate low‐pressure warning ifnon‐TPC Spec rated tires areinstalled. See Tire Pressure MonitorSystem on page 10‑67.

The Tire and Loading Informationlabel indicates the originalequipment tires on the vehicle. SeeVehicle Load Limits on page 9‑17for the label location and moreinformation about the Tire andLoading Information label.

Different Size Tires andWheelsIf wheels or tires are installed thatare a different size than the originalequipment wheels and tires, vehicleperformance, including its braking,ride and handling characteristics,stability, and resistance to rollovermay be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, tractioncontrol, and electronic stabilitycontrol, the performance of thesesystems can also be affected.

{ WARNING

If different sized wheels are used,there may not be an acceptablelevel of performance and safety iftires not recommended for thosewheels are selected. Thisincreases the chance of a crashand serious injury. Only use GMspecific wheel and tire systemsdeveloped for the vehicle, andhave them properly installed by aGM certified technician.

Uniform Tire QualityGradingQuality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width. Forexample:

Treadwear 200 Traction AATemperature A

The following information relatesto the system developed by theUnited States National HighwayTraffic Safety Administration(NHTSA), which grades tiresby treadwear, traction, andtemperature performance. Thisapplies only to vehicles sold inthe United States. The gradesare molded on the sidewalls ofmost passenger car tires. TheUniform Tire Quality Grading

(UTQG) system does not applyto deep tread, winter tires,compact spare tires, tires withnominal rim diameters of10 to 12 inches (25 to 30 cm),or to some limited-productiontires.

While the tires available onGeneral Motors passenger carsand light trucks may vary withrespect to these grades, theymust also conform to federalsafety requirements andadditional General Motors TirePerformance Criteria (TPC)standards.

All Passenger Car Tires MustConform to Federal SafetyRequirements In Addition ToThese Grades.

Treadwear

The treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government testcourse. For example, a tiregraded 150 would wear one anda half (1½) times as well on thegovernment course as a tiregraded 100. The relativeperformance of tires dependsupon the actual conditions oftheir use, however, and maydepart significantly from thenorm due to variations in drivinghabits, service practicesand differences in roadcharacteristics and climate.

Vehicle Care 10-79

Traction – AA, A, B, C

The traction grades, fromhighest to lowest, are AA, A, B,and C. Those grades representthe tire's ability to stop on wetpavement as measured undercontrolled conditions onspecified government testsurfaces of asphalt andconcrete. A tire marked C mayhave poor traction performance.Warning: The traction gradeassigned to this tire is based onstraight-ahead braking tractiontests, and does not includeacceleration, cornering,hydroplaning, or peak tractioncharacteristics.

Temperature – A, B, C

The temperature grades are A(the highest), B, and C,representing the tire's resistanceto the generation of heat and itsability to dissipate heat whentested under controlled

conditions on a specified indoorlaboratory test wheel. Sustainedhigh temperature can cause thematerial of the tire to degenerateand reduce tire life, andexcessive temperature can leadto sudden tire failure. The gradeC corresponds to a level ofperformance which allpassenger car tires must meetunder the Federal Motor SafetyStandard No. 109. Grades B andA represent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law. Warning: Thetemperature grade for this tire isestablished for a tire that isproperly inflated and notoverloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heatbuildup and possible tire failure.

Wheel Alignment and TireBalanceThe tires and wheels were alignedand balanced at the factory toprovide the longest tire life and bestoverall performance. Adjustments towheel alignment and tire balancingwill not be necessary on a regularbasis. However, check thealignment if there is unusual tirewear or if the vehicle is pulling toone side or the other. If the vehiclevibrates when driving on a smoothroad, the tires and wheels mightneed to be rebalanced. See yourdealer for proper diagnosis.

Wheel ReplacementReplace any wheel that is bent,cracked, or badly rusted orcorroded. If wheel nuts keep comingloose, the wheel, wheel bolts andwheel nuts should be replaced.If the wheel leaks air, replace it.Some aluminum wheels can berepaired. See your dealer if any ofthese conditions exist.

Your dealer will know the kind ofwheel that is needed.

Each new wheel should have thesame load-carrying capacity,diameter, width, offset and bemounted the same way as the one itreplaces.

Replace wheels, wheel bolts, wheelnuts, or Tire Pressure MonitorSystem (TPMS) sensors with newGM original equipment parts.

{ WARNING

Using the wrong replacementwheels, wheel bolts, or wheelnuts can be dangerous. It couldaffect the braking and handling ofthe vehicle. Tires can lose air,and cause loss of control, causinga crash. Always use the correctwheel, wheel bolts, and wheelnuts for replacement.

Notice: The wrong wheel canalso cause problems with bearinglife, brake cooling, speedometeror odometer calibration,headlamp aim, bumper height,vehicle ground clearance, and tireor tire chain clearance to thebody and chassis.

Whenever a wheel, wheel bolt,or wheel nut is replaced on a dualwheel setup, check the wheel nuttorque after 160, 1 600 and10 000 km (100, 1,000 and 6,000 mi)of driving. For proper torque, see“Wheel Nut Torque” underCapacities and Specifications onpage 12‑2.

If a Tire Goes FlatIt is unusual for a tire to blowoutwhile driving, especially if the tiresare maintained properly. If air goesout of a tire, it is much more likely toleak out slowly. But if there ever is ablowout, here are a few tips aboutwhat to expect and what to do:

If a front tire fails, the flat tirecreates a drag that pulls the vehicletoward that side. Take your foot offthe accelerator pedal and grip thesteering wheel firmly. Steer tomaintain lane position, and thengently brake to a stop, well off theroad, if possible.

A rear blowout, particularly on acurve, acts much like a skid andmay require the same correction asused in a skid. Stop pressing theaccelerator pedal and steer tostraighten the vehicle. It may bevery bumpy and noisy. Gently braketo a stop, well off the road,if possible.

{ WARNING

Driving on a flat tire will causepermanent damage to the tire.Re-inflating a tire after it hasbeen driven on while severelyunderinflated or flat may cause ablowout and a serious crash.Never attempt to re-inflate a tirethat has been driven on whileseverely underinflated or flat.Have your dealer or an authorizedtire service center repair orreplace the flat tire as soon aspossible.

{ WARNING

Lifting a vehicle and gettingunder it to do maintenance orrepairs is dangerous without theappropriate safety equipment andtraining. If a jack is provided withthe vehicle, it is designed only forchanging a flat tire. If it is used foranything else, you or others couldbe badly injured or killed if thevehicle slips off the jack. If a jackis provided with the vehicle, onlyuse it for changing a flat tire.

If a tire goes flat, avoid further tireand wheel damage by driving slowlyto a level place, well off the road,if possible. Turn on the hazardwarning flashers. See HazardWarning Flashers on page 6‑5.

Collision Damage Repair(U.S. and Canada)If the vehicle is involved in acollision and it is damaged, have thedamage repaired by a qualifiedtechnician using the properequipment and quality replacementparts. Poorly performed collisionrepairs diminish the vehicle resalevalue, and safety performance canbe compromised in subsequentcollisions.

Collision Parts

Genuine GM Collision parts are newparts made with the same materialsand construction methods as theparts with which the vehicle wasoriginally built. Genuine GMCollision parts are the best choice toensure that the vehicle's designedappearance, durability, and safetyare preserved. The use of GenuineGM parts can help maintain the GMNew Vehicle Limited Warranty.

Recycled original equipment partsmay also be used for repair. Theseparts are typically removed fromvehicles that were total losses inprior crashes. In most cases, theparts being recycled are fromundamaged sections of the vehicle.A recycled original equipment GMpart may be an acceptable choice tomaintain the vehicle's originallydesigned appearance and safetyperformance; however, the history ofthese parts is not known. Such partsare not covered by the GM NewVehicle Limited Warranty, and anyrelated failures are not covered bythat warranty.

Aftermarket collision parts are alsoavailable. These are made bycompanies other than GM and maynot have been tested for the vehicle.As a result, these parts may fitpoorly, exhibit premature durability/corrosion problems, and may not

perform properly in subsequentcollisions. Aftermarket parts are notcovered by the GM New VehicleLimited Warranty, and any vehiclefailure related to such parts is notcovered by that warranty.

Repair Facility

GM also recommends that youchoose a collision repair facility thatmeets your needs before you everneed collision repairs. Your dealermay have a collision repair centerwith GM-trained technicians andstate‐of‐the‐art equipment, or beable to recommend a collision repaircenter that has GM-trainedtechnicians and comparableequipment.

Insuring the Vehicle

Protect your investment in the GMvehicle with comprehensive andcollision insurance coverage. Thereare significant differences in thequality of coverage afforded byvarious insurance policy terms.Many insurance policies providereduced protection to the GMvehicle by limiting compensation fordamage repairs through the use ofaftermarket collision parts. Someinsurance companies will notspecify aftermarket collision parts.When purchasing insurance, werecommend that you ensure that thevehicle will be repaired with GMoriginal equipment collision parts.If such insurance coverage is notavailable from your currentinsurance carrier, consider switchingto another insurance carrier.

If the vehicle is leased, the leasingcompany may require you to haveinsurance that ensures repairs withGenuine GM Original EquipmentManufacturer (OEM) parts orGenuine Manufacturer replacementparts. Read the lease carefully, asyou may be charged at the end ofthe lease for poor quality repairs.

If a Crash Occurs

If there has been an injury, callemergency services for help. Do notleave the scene of a crash until allmatters have been taken care of.Move the vehicle only if its positionputs you in danger, or you areinstructed to move it by a policeofficer.

Give only the necessary informationto police and other parties involvedin the crash.

For emergency towing seeRoadside Assistance Program (U.S.and Canada) on page 13‑8 orRoadside Assistance Program(Mexico) on page 13‑11.

Managing the Vehicle DamageRepair Process

In the event that the vehicle requiresdamage repairs, GM recommendsthat you take an active role in itsrepair. If you have a pre-determinedrepair facility of choice, take thevehicle there, or have it towed there.Specify to the facility that anyrequired replacement collision partsbe original equipment parts, eithernew Genuine GM parts or recycledoriginal GM parts. Remember,recycled parts will not be coveredby the GM vehicle warranty.

Insurance pays the bill for the repair,but you must live with the repair.Depending on your policy limits,your insurance company mayinitially value the repair usingaftermarket parts. Discuss this withthe repair professional, and insist onGenuine GM parts. Remember,if the vehicle is leased, you may beobligated to have the vehiclerepaired with Genuine GM parts,even if your insurance coveragedoes not pay the full cost.

If another party's insurancecompany is paying for the repairs,you are not obligated to accept arepair valuation based on thatinsurance company's collision policyrepair limits, as you have nocontractual limits with that company.In such cases, you can have controlof the repair and parts choices aslong as the cost stays withinreasonable limits.

Event Data RecordersThis vehicle has an Event DataRecorder (EDR). The main purposeof an EDR is to record, in certaincrash or near crash-like situations,such as an airbag deployment orhitting a road obstacle, data that willassist in understanding how avehicle's systems performed. TheEDR is designed to record datarelated to vehicle dynamics andsafety systems for a short period oftime, typically 30 seconds or less.The EDR in this vehicle is designedto record such data as:. How various systems in the

vehicle were operating.. Whether or not the driver and

passenger safety belts werebuckled/fastened.

. How far, if at all, the driver waspressing the accelerator and/orbrake pedal.

. How fast the vehicle wastraveling.

This data can help provide a betterunderstanding of the circumstancesin which crashes and injuries occur.

Important: EDR data is recordedby the vehicle only if a non-trivialcrash situation occurs; no data isrecorded by the EDR under normaldriving conditions and no personaldata (e.g., name, gender, age, andcrash location) is recorded.However, other parties, such as lawenforcement, could combine theEDR data with the type ofpersonally identifying data routinelyacquired during a crashinvestigation.

To read data recorded by an EDR,special equipment is required, andaccess to the vehicle or the EDR isneeded. In addition to the vehiclemanufacturer, other parties, such aslaw enforcement, that have thespecial equipment, can read theinformation if they have access tothe vehicle or the EDR.

GM will not access this data orshare it with others except: with theconsent of the vehicle owner or,if the vehicle is leased, with theconsent of the lessee; in responseto an official request by police orsimilar government office; as part ofGM's defense of litigation throughthe discovery process; or, asrequired by law. Data that GMcollects or receives may also beused for GM research needs or maybe made available to others forresearch purposes, where a need isshown and the data is not tied to aspecific vehicle or vehicle owner.
