Supplemental Restraint System (SRS) “AIR
BAG” and “SEAT BELT PRE-TENSIONER”

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” 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):

●

For 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.

●

For 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:

●

To 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.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.

●

Do 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 “SEAT BELT PRE-TENSIONER”
connectors can be identified by yellow harness connector (and with yellow harness protector or
yellow insulation tape before the harness connectors).

CAUTION:

●

Before removing the seat belt pre-tensioner assembly, turn the ignition switch OFF, disconnect
both battery cables and wait at least 3 minutes.

●

Do not use electrical test equipment for seat belt pre-tensioner connector.

●

After replacing or installing seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner connector, check the system function. Refer to “SRS Operation Check” (RS-37) for details.

●

Do not disassemble buckle or seat belt assembly.

●

Replace anchor bolts if they are deformed or worn out.

●

Never oil tongue and buckle.

●

If any component of seat belt assembly is questionable, do not repair. Replace the whole seat
belt assembly.

●

If webbing is cut, frayed, or damaged, replace seat belt assembly.

●

When replacing seat belt assembly, use a genuine seat belt assembly.

●

After any collision, inspect all seat belt assemblies, including retractors and other attached
hardwares (i.e., guide rail set).
