Bus Certification and Vehicle Identification (VIN)Nameplate, Bus Weight Rating
The Vehicle Identification Number (VIN) nameplate is located on the face
of the dash panel near the entrance door. This nameplate certifies
compliance with all applicable Federal Motor Vehicle Safety Standards in
effect on the date the vehicle was manufactured. Included with the VIN is
the gross vehicle and axle weight ratings, tire size and inflation pressure,
and unit identification number.
GROSS VEHICLE WEIGHT RATING (GVWR)
GVWR applies to the loaded weight capacity of the vehicle. Do not load the
vehicle in excess of the GVWR.
GROSS AXLE WEIGHT RATING (GAWR)
GAWR applies to the load-carrying capacity of a single axle system as
measured at the tire-ground interfaces. Do not load any axle in excess of its
GAWR. The VIN nameplate shows the capacities of the front axle and rear
axle.
PASSENGER LOADING
This bus is designed to accommodate 38 seated passengers.
Accommodations are also provided for two wheelchair passengers.
Grabrails and stanchions are provided for any standing passengers.
Standing passengers should remain behind the yellow “standee line” at the
forward end of the aisle. Passenger loading should not exceed either the
GVWR or GAWR of the vehicle as indicated on the VIN nameplate. Actual
loads at the front and rear axle can only be determined by weighing the
bus. Consult your transit authority’s guidelines for the allowable number of
passengers.

Tires and Tire Traction
The original equipment tires shown on the VIN nameplate are selected to
provide the best overall tire performance under normal operating
conditions. When inflated to specified pressures, they have the capacity to
operate satisfactorily at all loads up to and including the full rated load.
The size, load rating and inflation pressure restrict the speeds at which the
bus can safely be operated. It is important to avoid over-inflating as well as
under-inflating. Cold inflation pressure must never exceed the amount
specified on the VIN nameplate.
CAUTION: A tire that is running while significantly under-inflated will
overheat, possibly resulting in a fire that may seriously damage the
vehicle.
TIRE TRACTION
A decrease in driving, cornering, and braking traction occurs when water,
snow, ice, gravel, or other material is on the road surface. Driving practices
and bus speed should be adjusted to the road conditions.
When driving on wet or slushy roads, it is possible for a wedge of water to
build up between the tire and road surface. This condition, known as
hydroplaning, may cause partial or complete loss of traction, which
adversely affects bus control and stopping ability. To reduce the possibility
of traction loss, the following precautions should be observed:
1. Reduce speed during rainstorms or when roads are slushy.
2. Reduce speed if road has standing water or puddles.
3. Maintain proper tire inflation.

Emergency and Safety Features
This bus is provided with several important features which are designed to
assure the safety of the operator and the passengers, as well as vehicles
and pedestrians in the vicinity of the bus. The operator should know how
these features work and should notify the dispatcher immediately, when it
is recognized that they are not operating properly.
BATTERY DISCONNECT SWITCHES
Two battery disconnect switches are mounted behind an access door in
the battery compartment, which is located midway on the roadside skirt
panels. These switches are used to disconnect the batteries from the
electrical system, such as in case of a fire or an accident. To operate the
switches, open the compartment door and place both switches in the “off”
position. To restore battery power, place both switch handles in the “on”
position.

BACK-UP ALARM
An audible beeper at the rear of the bus sounds whenever the transmission
is in reverse. The purpose of this alarm is to alert pedestrians and motorists
in the immediate area that the bus will be moving backward.
KNEELING ALARM
An audible beeper at the front of the bus sounds and a warning light near
the entrance door flashes whenever the kneeling system is activated. This
alarm alerts persons in the immediate vicinity that the front of the bus is
lowering.
WHEELCHAIR LIFT ALARM
An audible beeper at the front of the bus sounds and a warning light near
the entrance door flashes while the wheelchair lift is being deployed. These
alarms warn persons in the vicinity of the lift to remain clear of the
deployment zone.
BRAKE AND ACCELERATOR INTERLOCKS
Partial air pressure is applied to the rear axle service brakes and the
accelerator is disabled during the following conditions:
• Front or Rear Door Unlocked or Open
• Front or Rear Door Emergency Release
• Wheelchair Lift Operation
• Kneeling System Operation
• Fast Idle Operation
DOOR MASTER SWITCH
A door master switch is located inside the operator’s compartment door,
behind the operator’s seat. In case of a door system malfunction, placing
this switch in the “off” position will remove power from the door circuit
(closing both doors if open) and disable the brake interlock system. This
action will allow the bus to be moved from traffic or driven out-of-service to
a maintenance facility for repairs.
CAUTION: Under no condition should the bus be moved, except to a
point of safety, with the door master switch in the “Off” position.

PASSENGER DOOR RELEASE
Each passenger door is equipped with an emergency release feature to
manually open the doors if the operator’s door control system is not
functional. Release handles are located behind clear plastic break-out
panels above each door header. If a malfunction occurs in either door
system, the plastic panel can be broken by hand pressure to access the
release.
The front door release uses a valve lever that is rotated clockwise to
exhaust air pressure from the door. The rear door uses a mechanical pull
handle for release and opening of the door.

NABI OPERATOR’S MANUAL
Door Emergency Release
Appendix BBid #: WP17000232
Both release features must be returned to their original positions before
normal door operation is resumed.
FIRE SUPPRESSION SYSTEM
This bus is equipped with an automatic fire suppression system for the
engine compartment. If a fire is detected in the protected area, the system
releases a dry chemical agent into the compartment.
A control panel for monitoring the system is located above the forward end
of the operator’s window. System status is shown by a pair of LED’s. When
the green “SYSTEM OK” LED is illuminated, the system is normal and is
being continuously monitored by the controller. If a fire or high heat
condition is detected, the red “FIRE” LED illuminates, accompanied by an
alarm buzzer. The chemical agent will then be released into the affected
area to extinguish the fire. The buzzer may be silenced by pressing the
“Push to Silence” button on the control panel. When this button is pressed,
a small “Silence Engaged” LED beside the button illuminates, indicating
that the system is in the fire alarm warning mode, and the buzzer is not
operating.
Activation of the red “FIRE” LED will also trigger an engine shutdown in 0 to
30 seconds. Pressing the “Shutdown Reset” button before the “Relay
Engaged” LED illuminates will reset the timer and allow additional running
time. When the timer reaches “zero” the “Relay Engaged” LED will remain
0899 13
NABI OPERATOR’S MANUAL

Appendix BBid #: WP17000232
“on”. After the system has been activated, the red “FIRE” LED and alarm
buzzer will remain on until system maintenance is performed.
Emergency Actuator
If the system fails to detect a fire in the protected areas due to a system
fault, the system can be operated manually using the fire suppression
emergency actuator on the side console. To operate the system manually,
pull out the safety ring pin to break the plastic lock-wire seal, and press the
red “FIRE” button. This action will manually discharge the fire extinguishing
system.
The system control panel is also provided with an internal back-up battery.
In the event of a vehicle power failure (dead or disconnected vehicle
batteries), the back-up battery provides power to operate the fire
suppression system automatically for up to 24 hours. The red “Service
System” LED is illuminated when the system is operating on battery
back-up power.
SAFETY EQUIPMENT
A fire extinguisher and safety triangle kit is located behind the operator’s
seat. Consult your transit authority’s guidelines and procedures for further
information on use of this equipment.

NABI OPERATOR’S MANUAL
Operator’s Seat
Appendix BBid #: WP17000232
OPERATOR’S SEAT BELT
To reduce the chance of injury and/or
the amount of injury in accidents or
sudden stops, the operator should be
properly restrained at all times, using
the seat belt provided.
Adjust the seat to a comfortable driving
position and sit erect and back in the
seat.
Grasp the buckle end and the flat metal
“eye” end of the lap belt and insert the
metal tab into the open end of buckle
until a “snap” is heard.
Be sure to pull the retractor half of the
belt out to a solid stop before adjusting
to a snug fit, to make sure the belt webbing is completely unwound from the
retractor.
Position belt across lap as LOW ON HIPS as possible. To reduce the risk of
sliding under belt, adjust to a SNUG FIT by pulling on the end of the belt
extending from the latch plate or buckle.
WARNING:
A snug fit with the seat belt positioned low on the hips is
necessary to help lessen the chance of injury and/or the amount
of injury in an accident. This spreads the force exerted by the
seat belt in a collision over the strong hipbone structure rather
than across the soft abdominal area. Never use the same belt for
more than one person at a time; do not wear the belt without fully
extending the webbing from the retractor; do not wear belt in a
twisted position or allow belt or hardware to become damaged by
being pinched between the seat structural members.

Service Brake Operation
This bus is equipped with air-operated service brakes. Brakes are applied
by pressing the brake pedal, located on the floor to the left of the
accelerator. Varying degrees of brake application are obtained by varying
the distance the brake pedal is depressed.
Best braking is obtained by making the initial brake application gradually to
the extent of braking required, then reducing pressure gradually as speed
is reduced. This allows only slight pressure to remain in the brake
chambers at end of stop.
Do not “fan” the brake pedal. “Fanning” or quickly pressing and releasing
the pedal over and over, causes poor brake performance, wastes air
pressure, and causes excessive wear on brake components.
When the brake pedal is depressed, the rear-mounted stoplights will be on.
The instrument panel “Brake” indicator will also be illuminated.
WARNING:
Driving through water deep enough to wet brake components
may affect brake system performance, so that bus will not slow
down at the usual rate, and may pull to the right or left. Applying
the air brakes lightly will indicate if this has happened. To dry
them quickly, lightly apply the brakes while maintaining a safe
forward speed with an assured clear distance ahead and to the
sides until brake performance returns to normal.
AIR PRESSURE
Air pressure is important for the safe operation of the bus. Besides the
brake and air suspension system, other systems of the bus depend upon
air pressure for their operation.
Compressed air is supplied by the engine driven air compressor, which is
designed to maintain system pressure between 110 and 130 psi. The dual
needle air gauge registers pressure in the front and rear axle service brake
systems. At start-up, if system air pressure is below 80 psi, the “Low Air”
indicator and audible alarm will be on. Air pressure must be at least 90 psi
before the brakes can develop their full effectiveness. Also, the door
operating equipment and other air-operated devices will not work properly
with air pressure below 85 psi.
0899 31
NABI OPERATOR’S MANUAL
Appendix BBid #: WP17000232
If during operation, the “Low Air” indicator comes on and the alarm sounds,
stop the bus as quickly as possible and find the cause of air loss before
proceeding.
ANTI-LOCK BRAKING SYSTEM (ABS)
This vehicle is equipped with an anti-lock braking system (ABS) that
monitors and controls wheel speed during braking. If a wheel lockup is
detected during a brake application, this system regulates air pressure to
the affected wheel or wheels to prevent lockup. This action will result in
shorter stopping distances, improved steering control to avoid obstacles,
and greater stability on uneven traction surfaces.
In the event of a system malfunction, the ABS in the affected wheel(s) is
disabled, and reverts to normal braking. The instrument panel “ABS Fault”
indicator will illuminate to warn of this condition.
NOTE: The transmission retarder feature is automatically disabled when
the ABS is activated.
32 0899
NABI OPERATOR’S MANUAL
Appendix BBid #: WP17000232
Parking Brake Operation
The parking brake is an air-released, spring
applied system designed to prevent movement
of a parked vehicle. The parking brake control
valve is located on the operator’s side console.
To release the parking brake, push the control
valve in and hold for approximately one second.
To apply the parking brake, pull out on the
control valve knob. The instrument panel “Park
Brake” indicator will illuminate when the parking
brake is on.
The parking brake system is designed to automatically apply the parking
brake if front and rear service brake reservoir pressure falls below 40 psi.
When system air pressure is low, build air pressure to at least 80 psi or
more (as indicated by the dual air pressure gauge) before pushing the
valve knob in.
WARNING:
The parking brake should always be applied before leaving the
operator’s seat. This will prevent the bus from moving
unexpectedly, which could result in personal injury and/or
property damage.
EMERGENCY PARKING BRAKE RELEASE VALVE
If automatic parking brake application occurs
under hazardous circumstances, an emergency
release of the parking brake can be obtained
using the emergency release valve. Press and
hold the emergency release valve to move the
bus to a safe location. Release of pressure on
the knob instantly reapplies the parking brake.
CAUTION: Emergency release of the parking
brake is limited to the air supply of the
emergency reservoir.

RANGE SELECTION
NEUTRAL (N) – Use Neutral when starting the engine, checking bus
accessories, and during extended periods of engine idle operation. The
transmission electronic control system is designed to select Neutral
automatically at engine start-up. Always apply the parking brake when
starting the engine, or when leaving the bus unattended with the engine
running.
WARNING:
If the engine starts in any range other than Neutral, report
condition to maintenance personnel immediately.
NOTE: Always apply the brake pedal before shifting from Neutral (N) to
Drive (D) or Reverse (R). These shifts are inhibited when the bus is moving
or engine speed is above idle.
REVERSE (R) – Select this range to back the bus. Completely stop the
vehicle before shifting from a forward range to Reverse or from Reverse to
a forward range. When the transmission is in reverse, a back-up alarm at
rear of bus provides an audible warning.
DRIVE (D) – Select this range for all normal driving conditions. As vehicle
speed increases, the transmission will automatically through each range.
As the vehicle slows, the transmission will downshift automatically.
ñ(UP)ò(DOWN) ARROW BUTTONS – The arrow buttons can be used to
select individual forward ranges of 5, 4, 3, 2, or 1. Occasionally, road
conditions, load, or traffic conditions will make it desirable to restrict
automatic shifting to a lower range. Lower ranges provide greater engine
braking for going down grades (the lower the range, the greater the braking
effect).
Push the up or down arrow to the desired range. The digital display panel
will indicate the range selected. If a lower range is selected while driving,
the transmission may not downshift until vehicle speed is reduced.
ACCELERATOR CONTROL
The position of the accelerator pedal influences the timing at which
automatic shifting occurs. When the pedal is fully depressed, upshifts will
occur automatically at higher engine speeds. A partially depressed position
of the pedal will cause the upshifts to occur at lower engine speeds.
38 0899
NABI OPERATOR’S MANUAL
Appendix BBid #: WP17000232
Upshifting will not occur if the load or slope prevents the bus from reaching
the required speed. In all cases, the transmission is designed to shift to the
highest gear chosen or to a gear that can handle the load.
RETARDER OPERATION
The retarder is a hydrodynamic brake that functions according to the gear
in use. Application of the retarder is recommended for lengthy grades or
when slowing from high speeds. This reduces wear on the air-operated
service brakes and in an emergency, the full braking affect of the service
brakes is available. The retarder is engaged automatically through the
brake pedal.
Retarder operation occurs as the brake pedal is depressed. Retarder
application begins before a complete service brake application is made.
Upon a full service brake application, both the retarder and the service
brakes are applied.
NOTE: The retarder is automatically disabled whenever the vehicle ABS
(Anti-Lock Brake System) is active.
PARKING THE BUS
There is no “Park” position on the shift selector. Always select Neutral (N)
and apply the parking brake before stopping the engine, or any time the
bus is running unattended.
WARNING:
To avoid personal injury and property damage, always place
transmission in Neutral (N) and apply the parking brake before
leaving the operator’s seat. This will prevent the bus from moving
if the accelerator pedal is accidentally pressed. Always select
Neutral (N) before stopping the engine and apply the parking
brake to prevent the bus from moving.
CHECK TRANSMISSION INDICATOR
The “Check Trans” light is located on the instrument panel and has two
functions:
1. It is used as a warning indicator to alert the operator that a potentially
serious problem has been detected, and the shift selection will be
impaired.
0899 39
NABI OPERATOR’S MANUAL
Appendix BBid #: WP17000232
2. Each time the engine is started, this light will illuminate, then turn-off
after a few seconds. This momentary lighting provides a lamp check
and a system check. Illumination of the light during vehicle operation
(other than start-up) is accompanied by an audible alarm, indicating
that shifting is being restricted.
CAUTION: If the “Check Trans” light remains illuminated, stop the
vehicle as soon as possible and report the condition to maintenance
personnel.

Wheelchair Lift
INTRODUCTION
The wheelchair lift is designed to assist the mobility impaired when
entering and leaving the bus by providing a wheelchair lift at the front door.
Lift operation is controlled by five switches on the instrument panel.
Certain safety precautions, listed below, must be followed when using this
equipment. The operator should adhere to these precautions and
guidelines and have a thorough understanding of this information before
attempting to use this device.
SAFETY PRECAUTIONS AND GUIDELINES
The following safety precautions and operating guidelines must be
complied with at all times when operating the wheelchair ramp:
• Always operate the lift with bus parked on level ground. The
minimum safe clearance required for deployment is an area five feet
wide by six feet in length.
• Always apply the parking brake before using the lift.
• The transmission must be in Neutral (N).
• Inspect the lift prior to each use. Perform “Daily Safety Check,” as
indicated below, before operating bus in service.
• When using the lift, the occupant should always face inward during
loading and outward during unloading operations.
• Be certain the wheelchair fits safely on the platform and does not
extend over the edges.
• Do not place arms, legs, or clothing in or near moving parts. Keep
others clear while operating.
• Use extreme care in wet conditions. Wheelchair brakes are less
effective if the platform and/or wheelchair wheels are wet.
DAILY SAFETY CHECK
Inspect the wheelchair lift before each use and check that the following
conditions are met before operating:
• All functions operate properly. If unusual noises or movements exist,
report the condition to maintenance personnel.

WARNING
Care must be used when activating the following switch (W/CL
O’RIDE) to prevent injury of a wheelchair passenger or people in
the lift deployment area. Always verify that the lift platform is clear
of passengers or objects.
SENSOR OVERRIDE SWITCH (W/CL O’RIDE)
The wheelchair lift is equipped with sensor switches that prevent it from
raising or stowing if a passenger or object is in contact with the sensors. If
a malfunction occurs in the sensor system when the platform is
unoccupied, the platform may not raise or stow.
To stow or raise the platform during this type of malfunction, press and hold
the ”W/CL O’RIDE” switch along with both “STOW” switches. This should
only be done if the lift will not raise or stow normally, and only after the
operator has verified that the platform and lift area is clear.

Destination Sign Equipment
DESCRIPTION
The destination sign equipment consists of front, two side signs and a rear
sign, with a front-mounted, curtain style run sign. This system is
electronically controlled using Light Emitting Diode (LED) display
elements. When the “Master Run” switch is in “Day”, “Night”, or “Park”
positions, the sign system is operable. When the “Master Run” switch is
rotated to the “Off” position, the sign equipment will go into an “auto-blank”
mode in which all of the dots are turned to their “black” or “off” condition.
Destination information is selected using the Operator Console Unit
(OCU), located on the sign compartment door above the windshield.
Destination codes are predefined by the transit authority and are made
available on an address code/destination listing.
In addition to normal destination listings, this sign system can also provide
a variety of Public Relations (P/R) messages. These include TRAINING
BUS, HAPPY HOLIDAYS, etc. This feature is normally used alternately
with the normal destination listing. The P/R code listing is pre-defined and
provided by the transit authority.
OPERATOR CONSOLE UNIT
The Operator Console Unit consists of a 28-key keypad, which is used to
select the destination information. The most commonly used keys are the
DEST A, DEST B, 0 – 9 keys, and the ENTER key. The rear of the unit
0899 49
NABI OPERATOR’S MANUAL
Operator Console Unit
Appendix BBid #: WP17000232
contains a beeper that “beeps” each time a key is pressed, which confirms
that it has been activated. The keypad keys and functions are as follows:
MENU – This is used as part of a sequence to upload information to the
sign system.
ROUTE – This is a seldom used key for systems in which a route number
may be manually selected by the operator for use in conjunction with the
destination information already present on the sign. In most systems, this
feature is not enabled.
P/R – This is used to enable public relations code entry. A P/R message
alternately “toggles” with the normal destination sign display. Setting the
P/R to “0” will eliminate this feature.
DEST A AND DEST B – These keys are always functional and are used to
set or change a destination display.
0 THROUGH 9 KEYS – These are used to select a given address in the
transit authority destination listing.
A THROUGH F KEYS – These keys are only used in a
hexadecimal-addressing scheme and are not used by the operator.
ARROW KEYS – These keys are only used by maintenance personnel
when uploading new data to the sign system.
ENTER – This is usually the last key to be pressed in any character
sequence for entering a destination code or changing a destination display
on the sign system.

Passenger Stop Request System
The passenger stop request system consists of pull cords, touch tape
switches, a dual-tone signal chime, a next stop sign, and two instrument
panel indicator lights. Pull cords are routed along the side windows and are
accessible by both seated and standing passengers. Pressure-sensitive
touch tape switches are provided in the mobility device securement areas.
The signal chime is located in the operator’s compartment. A next stop sign
is located on the ceiling at the front of the bus and illuminates to provide
passengers with visual indication of a stop.
When a pull cord is actuated, the chime will sound once and the next stop
sign will illuminate. The instrument panel “STOP ” indicator will also light to
alert the operator of a stop request.
If a touch tape switch is used to activate the system, the chime will sound
twice and the instrument panel “W/C STOP” indicator will illuminate.
Whenever the passenger stop request has sounded, the system locks out
the pull cords from further chime activation. The indicator lights will remain
on until the door controller is moved to a door open position and then back
to a door closed position.
