Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001516581
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.
Liquid GasketINFOID:0000000001381524
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
 Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Apply liquid gasket to the liquid gasket application surface.
Use Genuine liquid gasket or equivalent.
 Within five minutes of liquid gasket application, install the mating component.
 If liquid gasket protrudes, wipe it off immediately.
 Do not retighten mounting bolts or nuts after the installation.
 After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.

use) to remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the Tool.
Use Genuine Silicone RTV Sealant or equivalent. Refer to
GI-27, "
Recommended Chemical Products and Sealants".
 Within 5 minutes of liquid gasket application, install the mating
component.
 If liquid gasket protrudes, wipe it off immediately.
 Do not retighten bolts or nuts after the installation.
 Wait 30 minutes or more after installation before refilling

Precaution for Liquid GasketINFOID:0000000001381534
REMOVAL OF LIQUID GASKET
 After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the liquid gasket.
CAUTION:
Be careful not to damage the mating surfaces.
 In areas where the cutter is difficult to use, use a plastic hammer to
lightly tap (1) the tool into place and slide (2) side-to-side.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the
gasket application surface and the mating surface.
 Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts and bolt holes.
2. Wipe the gasket application surface and the mating surface with
white gasoline (lighting and heating use) to remove adhering
moisture, grease and foreign materials.
3. Attach the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.
