AFTER A COLLISION

WARNING:

Inspect all seat belt assemblies including retractors and attached hardware after any collision.
NISSAN/INFINITI 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. Fail-
ure to do so could result in serious personal injury in an accident. Seat belt assemblies not in use dur-
ing a collision should also be replaced if either damage or improper operation was noted.

• The seat belt is damaged in an accident (i.e. torn webbing, bent retractor or guide, etc.).
• The seat belt attaching point is damaged in an accident. Inspect the seat belt attaching area for damage or

PRECAUTIONS

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

INFOID:0000000011006819

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. 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 Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000011006820

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition power source and accessory

power source to the OFF, then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect

both battery cables.

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

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

For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.

OPERATION PROCEDURE

1.

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

2.

Open driver door.

3.

Turn the ignition switch to the ON position.
(At this time, the steering lock will be released.)

4.

Turn the ignition switch to OFF position with driver door open.

5.

Wait for 3 minutes or longer with driver door open.
NOTE:
• Do not close driver door because the steering wheel locks when driver door is closed.
