Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, help to reduce the risk or severity of injury to the driver and front passenger in certain types
of collision. The SRS system composition which is available to NISSAN MODEL P11 is as follows (The
composition varies according to the destination and optional equipment):
lFor a frontal collision
The Supplemental Restraint System consists of driver's air bag module (located in the center of the
steering wheel), front passenger's air bag module (located on the instrument panel on passenger's side),
seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
lFor a side collision
The Supplemental Restraint System consists of air bag modules (located in the outer side of front seats),
satellite sensor, diagnosis sensor unit (one of components of supplemental air bags for a frontal collision),
wiring harness, warning lamp (one of components of supplemental air bags for a frontal collision).
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. Spiral cable and SRS wiring harnesses except ªSEAT BELT PRE-TENSIONERº
connectors can be identified by yellow harness connector (and with yellow harness protector or
yellow insulation tape before the harness connectors).
CAUTION:
lBefore removing the seat belt pre-tensioner assembly, turn the ignition switch OFF, disconnect
both battery cables and wait at least 3 minutes.
lDo not use electrical test equipment for seat belt pre-tensioner connector.
lAfter replacing or installing seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner connector, check the system function. Refer to ªSRS Operation Checkº (RS-37) for details.
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 (i.e., guide rail set).

Precautions for SRS ªAIR BAGº and ªSEAT
BELT PRE-TENSIONERº Service
lDo not use electrical test equipment to check the SRS unless instructed to do in this Service Manual.
lBefore servicing the SRS, turn ignition switch ªOFFº, disconnect both battery cables and wait at least 3
minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
lDiagnosis sensor unit must always be installed with their arrow marks ªSº 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 driver's and passenger's air bag modules with the pad
side facing upward and place side air bag module (built-in type) standing with stud bolt side setting bot-
tom.
lConduct self-diagnosis to check entire SRS for proper function after replacing any components.
lAfter air bag inflates, the front instrument panel assembly should be replaced if damaged.
