The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.

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/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

●

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Precaution for Seat Belt Service

EHS00084

CAUTION:

●

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

●

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

●

After replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner connector, check the system function. Refer to

SRS-20, "SRS Operation Check"

●

Do not use 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 A COLLISION

WARNING:

Inspect all seat belt assemblies including retractors and attaching hardware after any collision.
NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the col-
lision was minor and the belts show no damage and continue to operate properly. Failure to do so
could result in serious personal injury in an accident. Seat belt assemblies not in use during a colli-
sion should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioner
should be replaced even if the seat belts are not in use during a frontal collision in which the air bags
are deployed.
Replace any seat belt assembly (including anchor bolts) if:

●

The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).

●

The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.)

●

The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.

●

Anchor bolts are deformed or worn out.

●

The seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in
which the air bags are deployed.
