Supplemental Restraint System (SRS) ``AIR
BAG'' (4WD models)
The Supplemental Restraint System ``AIR BAG'', used along with a seat belt, helps to reduce the risk or
severity of injury to the driver in a frontal collision. The Supplemental Restraint System consists of air bag
module (located in the center of the steering wheel), diagnosis sensor unit, warning lamp, wiring harness
and spiral cable.
WARNING:
lTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses are covered with yellow insulation either just before the
harness connectors or for the complete harness, for easy identification.

PRECAUTION
RS-1

CAUTION:
lDo not disassemble buckle or seat belt assembly.
lReplace anchor bolts if they are deformed or worn out.
lNever oil tongue and buckle.
lIf any component of seat belt assembly is questionable, do not repair. Replace the whole seat
belt assembly.
lIf webbing is cut, frayed, or damaged, replace seat belt assembly.
lWhen replacing seat belt assembly, use a genuine seat belt assembly.
lAfter any collision, inspect all seat belt assemblies, including retractors and other attached
hardwares.

Precautions for SRS ``AIR BAG'' Service
lDo not use a circuit tester to check SRS circuits unless instructed to in this Service Manual.
lBefore servicing the SRS, turn ignition switch ``OFF'', disconnect both battery cables and wait for at least
3 minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag to deploy.
Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
lFor 2WD models, do not separate diagnosis sensor unit from steering wheel.
lFor 4WD models, diagnosis sensor unit must always be installed with their arrow marks ``S'' pointing
towards the front of the vehicle for proper operation. Also check diagnosis sensor unit for cracks,
deformities or rust before installation and replace as required.
lThe spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt
to turn steering wheel or column after removal of steering gear.
lHandle air bag module carefully. Always place it with the pad side facing upward.
lConduct self-diagnosis to check entire SRS for proper function after replacing any components.
