PRECAUTIONPRECAUTIONSPrecaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000004025017

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used alongwith a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certaintypes of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRSsystem uses the seat belt switches to determine the front air bag deployment, and may only deploy one frontair 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 AIRBAG” and “SEAT BELT” of thisService 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 byan authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personalinjury caused by unintentional activation of the system. For removal of Spiral Cable and Air BagModule, see the “SRS AIRBAG”.

• 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 harnessconnectors.

Service INFOID:0000000004025015

• 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 bagand seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3minutes have elapsed.

• Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of thevehicle 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 steeringwheel and column after removal of steering gear.

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

Occupant Classification System Precaution INFOID:0000000004025016

• Replace Occupant Classification System control unit and passenger front seat cushion as an assembly.Refer to SE-32, "Removal and Installation".
