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

INFOID:0000000005243347

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:

• 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 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 the “SRS AIR BAG”.

• 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 har-
ness connectors.

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

WARNING:

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, DO NOT 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:0000000005243348

CAUTION:

• Before removing the front seat belt pre-tensioner assembly, turn the ignition switch OFF, disconnect

the battery negative terminal and wait at least 3 minutes.

• Never use electrical test equipment for front seat belt pre-tensioner connector.
• After replacing or reinstalling front seat belt pre-tensioner assembly, or reconnecting front seat belt

pre-tensioner connector, check the system function. Refer to 

SRC-16, "Diagnosis Description"

.

• Never use disassembled 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, never repair. Replace the entire 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 attached hardware after any collision.
Should 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 normaly. Failure to do
so could result in serious personal injury in an accident. Seat belt assemblies not in use during a col-
lision should also be replaced if either damage or improper operation is noted. Seat belt pre-tension-
ers 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:
