PRECAUTION

PRECAUTIONS

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

INFOID:0000000008454960

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.

Service

INFOID:0000000008454961

• Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3

minutes.
For approximately 3 minutes after the battery negative terminal is removed, it is still possible for the air bag
and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3
minutes have elapsed.

• Diagnosis sensor unit must always be installed with their arrow marks “

⇐

” pointing towards the front of the

vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installa-
tion and replace as required.

• The spiral cable must be aligned in the neutral position since its rotations are limited. Do not turn steering

wheel and column after removal of steering gear.

• Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side

facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.

• Conduct self-diagnosis to check entire SRS for proper functioning after replacing any components.
• After air bag inflates, the front instrument panel assembly should be replaced if damaged.
• Always replace instrument panel pad following front passenger air bag deployment.
