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

INFOID:0000000001297371

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.

Precaution for Liquid Gasket

INFOID:0000000001297372

REMOVAL OF LIQUID GASKET SEALING

• After removing nuts and bolts, separate the mating surface, using Tool and remove old liquid gasket sealing.    

CAUTION:

Be careful not to damage the mating surfaces.

• Tap Tool to insert it, and then slide it by tapping on the side as

shown.

• In areas where Tool is difficult to use, use plastic hammer to lightly

tap the parts, to remove it.

CAUTION:

If for some unavoidable reason suitable tool such as screw-
driver is used, be careful not to damage the mating surfaces.

LIQUID GASKET APPLICATION PROCEDURE

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

GI-26, "Recommended Chemical Products and Sealants"

. 

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.

• As for the bolt holes, normally apply the liquid gasket inside

the holes. If specified in the procedure, it should also be
applied outside the holes.

• 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

engine with engine oil and engine coolant.

CAUTION:

If there are specific instructions in this manual, observe them.
