PRECAUTIONS

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

INFOID:0000000009560124

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 SR and SB section 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 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 three minutes before performing any service.

Service

INFOID:0000000009015644

• Never 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 3 minutes

or more.

For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-

tensioner to deploy. Therefore, never work on any SRS connectors or wires until at least 3 minutes have

passed.

• 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 with the neutral position since its rotations are limited. Never 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 function 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.

• Never solder the harness when making repairs. Check that harness is not pinched and that there is no con-

tact with other components.

• Never allow harness to come in contact with oil, grease, waste oil, or water.

• Never insert foreign materials, such as a screwdriver, into the harness connector. (This is to prevent acci-

dental activation caused by static electricity.)

• Always use CONSULT or SRS air bag warning lamp to perform the circuit diagnosis. (Never use an electric

tester such as a circuit tester.)
