PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000009161826

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution for Seat Belt Service

INFOID:0000000009161827

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 front seat belt pre-

tensioner connector, check the system function. Refer to 

SRC-8, "Diagnosis Description"

.

• 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 NISSAN 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).
• 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.

Precaution for Battery Service

INFOID:0000000009161828

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
