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 may include seat belt switch inputs and dual stage front air bag modules. If
equipped with 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 Manual.

The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.

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.

●

The vehicle may be equipped with a passenger air bag deactivation switch which can be operated
by the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled
and will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled
and could inflate for certain types of collision. After SRS maintenance or repair, make sure the
passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehicle
arrived for service.

Precautions for Seat Belt Service

EHS000SI

CAUTION:

●

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

●

After replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner assembly connector, ensure entire SRS operates properly. Refer to

SRS-20, "SRS Opera-

tion Check"

●

Do not disassemble buckle or seat belt assembly.

●

Do not reuse seat belt anchor bolts after removal. Replace with new ones.

●

Never oil tongue and buckle.

●

If any component (including anchor bolts) 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 NISSAN seat belt assembly.

PRECAUTIONS

SB-3

After A Collision

EHS000SJ

WARNING:

●

Inspect all seat belt assemblies including retractors, buckles and attaching hardware after any col-
lision.

●

NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the
collision 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
collision should also be replaced if either damage or improper operation is noted. Seat belt
assemblies which are equipped with pre-tensioners 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 after minor collisions when 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 assembly is equipped with a pre-tensioner, even if the seat belt is not in use during a colli-
sion in which the air bags are deployed.
