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

INFOID:0000000005266525

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 SR 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 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 SR 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 har-

ness connectors.

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

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion 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:0000000005266526

CAUTION:

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

battery terminals and wait at least three minutes. For approximately three minutes after the battery

terminals have been removed, it is still possible for the air bag and seat belt pretensioner to deploy.

Therefore, do not attempt work on any SRS connectors or wires until at least three minutes have

passed.

• After replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-

sioner assembly connector, make sure entire SRS operates properly. Refer to 

SRC-13, "SRS Opera-

tion Check"

.

• 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 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

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 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.

OCCUPANT CLASSIFICATION SYSTEM

• Replace occupant classification system control unit and passenger front seat cushion as an assembly.

SE-51, "Removal and Installation"

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000005266527

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″LOCK″ position.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-

anism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and

steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, follow the procedure below before

starting the repair operation.

OPERATION PROCEDURE

1. Connect both battery cables.

NOTE:

Supply power using jumper cables if battery is discharged.

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the 

″ACC″ position. At this time, the

steering lock will be released.

3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be

rotated.

4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the 

″LOCK″ position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

6. Perform a self-diagnosis check of all control units using CONSULT-III.
