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

INFOID:0000000009886465

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 SR and SB section of this Service Man-

ual.

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 3 minutes before performing any service.

Precaution for Liquid Gasket

INFOID:0000000009886466

remove the old liquid gasket using Tool.

CAUTION:

Do not damage the mating surfaces.

• Tap the seal cutter to insert it (1).

• In areas where the Tool is difficult to use, lightly tap to slide it (2).

< PRECAUTION >

1. Remove the old liquid gasket adhering to the gasket application

surface and the mating surface using suitable tool.

• Remove the liquid gasket completely from the groove of the

liquid gasket application surface, bolts, and bolt holes.

2. Thoroughly clean the mating surfaces and remove adhering

moisture, grease and foreign material.

3. Attach the liquid gasket tube to the Tool.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

4. Apply the liquid gasket without breaks to the specified location

with the specified dimensions.

• If there is a groove for the liquid gasket application, apply the

liquid gasket to the groove.

• Normally apply the liquid gasket on the inside edge of the bolt

holes. Also apply to the outside edge of the bolt holes when

specified in the procedure.

• Within five minutes of liquid gasket application, install the mat-

ing component.

• If the liquid gasket protrudes, wipe it off immediately.

• Do not retighten after the installation.

• Wait 30 minutes or more after installation before refilling the
