helpstoreducetheriskorseverity of injury to the driver and front passenger in a frontal collision. The Supplemental Restraint Systemconsists of air bag modules (located in the center of the steering wheeland in the instrument panelon thepassenger side), a diagnosis sensor unit, a crash zone sensor, warning lamp, wiring harness and spiral cable.The vehicle is equipped with a passenger air bag deactivation switch. Because no rear seat exists where arear-facingchildrestraintcanbeplaced,theswitchisdesignedtoturnoffthepassengerairbagsothatarear-facing child restraint can be used in the front passenger seat. The switch is located in the center of theinstrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag isenabled and could inflate in a frontal collision. When the switch is turned to the OFF position, the passengerair bag is disabled and will not inflate in a frontal collision. A passenger air bag OFF indicator on the instru-ment panel lights up when the passenger air bag is switched OFF. The driver air bag always remains enabledand is not affected by the passenger air bag deactivation switch.Information necessary to service the system is included in the RS section of this Service Manual.WARNING:G To avoid rendering the SRS inoperative, which could increase the risk of personal injury or deathin the event of a collision which would result in air bag inflation, all maintenance should be per-formed by an authorized NISSAN dealer.G Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-sonal injury caused by unintentional activation of the system.G Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisServiceManual. SRSwiringharnessesarecoveredwithyellowinsulationeitherjustbeforetheharness connectors or on the complete harness, for easy identification.G The vehicle is equipped with a passenger air bag deactivation switch which can be operated bythe customer. When the passenger air bag is switched OFF, the passenger air bag is disabled andwill not inflate in a frontal collision. When the passenger air bag is switched ON, the passenger airbag is enabled and could inflate in a frontal collision. After SRS maintenance or repair, make surethe passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehiclearrived for service.PRECAUTIONS AND PREPARATIONEL-4DescriptionHARNESS CONNECTOR (TAB-LOCKING TYPE)G The tab-locking type connectors help prevent accidental looseness or disconnection.G The tab-locking type connectors are disconnected by pushing or lifting the locking tab(s).

Aftertouchingabattery,donottouch or rub your eyes until you have thoroughly washed yourhands. If the acid contacts the eyes, skin or clothing, immedi-ately flush with water for 15 minutes and seek medical atten-tion.Normally the battery does not require additional water.However, whenthebatteryisusedundersevereconditions,adding distilled water may be necessary during the battery life.SEL001KGRemove the cell plug using a suitable tool.G Add distilled water up to the MAX level.SEL005ZSULPHATIONA battery will be completely discharged if it is left unattended for alongtimeandthespecificgravitybecomeslessthan1.100. Thismay result in sulphation on the cell plates.To determine if a battery has been sulphated, note its voltage andcurrent when charging it. As shown in the figure, less current andhigher voltageareobservedintheinitial stageof chargingsul-phated batteries.A sulphated battery may sometimes be brought back into serviceby means of a long, slow charge, 12 hours or more, followed by abattery capacity test.SEL442DSPECIFIC GRAVITY CHECK1.

If the parking brake is appliedbefore the engine is started, the daytime lights will not be illuminated. The daytime lights will illuminate oncethe parking brake is released. Thereafter, the daytime lights will continue to operate when the parking brakeis applied. If the daytime light control unit receives a ground signal from the generator, the daytime lights willnot be illuminated. The daytime lights will illuminate once a battery positive voltage signal is sent to the day-time light control unit from the generator.Power is supplied at all times:G through 15A fuse (No. , located in the fuse and fusible link box)G to daytime light control unit terminal3 andG to lighting switch terminal8 .Power is also supplied at all times:G through 15A fuse (No. , located in the fuse and fusible link box)G to daytime light control unit terminal2 andG to lighting switch terminal5 .With the ignition switch in the ON or START position, power is supplied:G through 7.5A fuse [No. , located in the fuse block (J/B)]G to daytime light control unit terminal12 .With the ignition switch in the START position, power is supplied:G through 7.5A fuse [No. , located in the fuse block (J/B)]G to daytime light control unit terminal1 .Ground is supplied to daytime light control unit terminal9 through body groundsE12 andE54 .HEADLAMP OPERATIONLow beam operationWhen the lighting switch is turned to headlamp ON (2ND) position, LOW BEAM (B), power is supplied:G from lighting switch terminal7G to RH headlamp terminalDG to daytime light control unit terminal4 .Ground is supplied to RH headlamp terminalE through body groundsE12 andE54 .Also, when the lighting switch is turned to headlamp ON (2ND) position, LOW BEAM (B), power is supplied:G from lighting switch terminal10G to LH headlamp terminalD .Ground is supplied:G to LH headlamp terminalEG from daytime light control unit terminal7G through daytime light control unit terminal9G through body groundsE12 andE54 .With power and ground supplied, the low beam headlamps illuminate.High beam operation/flash-to-pass operationWhen the lighting switch is turned to headlamp ON (2ND) position, HIGH BEAM (A) or FLASH TO PASS (C)position, power is supplied:G from lighting switch terminal6G to terminalM of RH headlamp.When the lighting switch is turned to headlamp ON (2ND) position, HIGH BEAM (A) or FLASH TO PASS (C)position, power is supplied:G from lighting switch terminal9G to daytime light control terminal5G to combination meter terminal17 for the high beam indicatorG through daytime light control terminal6G to terminalM of LH headlamp.Ground is supplied in the same manner as low beam operation.Ground is supplied to terminal16 of the combination meter through body groundsM14 andM68 .With power and ground supplied, the high beam headlamps and HI BEAM indicator illuminate.GIMAEMLCECFECLMTATTFPDFARABRSTRSBTHAELIDXHEADLAMP Daytime Light System EL-47DAYTIME LIGHT OPERATIONWiththeenginerunning, thelightingswitchintheOFForparkinglamp(1ST)positionandparkingbrakereleased, power is supplied:G to daytime light control unit terminal3G through daytime light control unit terminal6G to terminalM of LH headlampG through terminalE of LH headlampG to daytime light control unit terminal7G through daytime light control unit terminal8G to terminalM of RH headlamp.Ground is supplied to terminalE of RH headlamp through body groundsE12 andE54 .Because the high beam headlamps are now wired in series, they operate at half illumination.Operation (For Canada)After startingtheenginewiththelightingswitchintheOFForparkinglamp(1ST)position, theheadlamphighbeamautomati-cally turns on.
