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 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 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.

Service

INFOID:0000000006219947

• 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-III or SRS air bag warning lamp to perform the circuit diagnosis. (Never use an elec-

tric tester such as a circuit tester.)

• Never enter in the deployment area of the pop-up roll bar. Never put an object in the deployment area of the

pop-up roll bar. (This is to prevent injury in case of an unintentional deployment.)

PRECAUTIONS

SRC-7

< PRECAUTION >

SRC

• When handling a pop-up roll bar, always grip the frame and handle carefully.
• Never reuse a pop-up roll bar that has previously deployed.
• Modification of the pop-up roll bar may cause unintentional deployment or a malfunction. Never disassemble

or modify the pop-up roll bar.

• Never allow the pop-up roll bar to be impacted (by dropping or otherwise). Always replace the pop-up roll bar

if impacted.

• When repairing the surrounding area of the pop-up roll bar, be careful not to apply excessive heat when

welding or otherwise. Remove the pop-up roll bar in advance, if necessary. Be careful when modifying the
mounting area or installing other parts because an incorrect procedure may cause damage or a malfunction.

• Never disassemble the pop-up roll bar.
• Never expose the pop-up roll bar to temperatures exceeding 90

C (194

F).

• Never allow oil, grease, detergent, or water to come in contact with the pop-up roll bar.
