PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612895
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PrecautionINFOID:0000000001328027
 Disconnect both battery cables in advance.
 Do not tamper with or force air bag lid open, as this may adversely affect air bag performance.
 Be careful not to scratch pad and other parts.
 When removing or disassembling any part, be careful not to damage or deform it. Protect parts, which may get in the way with cloth.
 When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.
 Keep removed parts protected with cloth.
 If a clip is deformed or damaged, replace it.
 If an unreusable part is removed, replace it with a new one.
 Tighten bolts and nuts firmly to the specified torque.
 After re-assembly has been completed, make sure each part functions correctly.
 Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.
 Do not use any organic solvent, such as thinner or benzine.

• Check for the correct installation status prior to removal or disassembly. If matching marks are required, becertain they do not interfere with the function of the parts when applied.
 Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
 Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
 Check appearance of the disassembled parts for dam age, deformation, and unusual wear. Replace them
with a new ones if necessary.
 Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
 In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-
ening sequence is specified, observe it.
 Clean and flush the parts sufficiently and blow-dry them.
 Be careful not to damage sliding surfaces and mating surfaces.
 When applying sealant, remove the old sealant from t he mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
 Always use shop paper for cleaning the inside of components.
 Avoid using cotton gloves or shop rags to prevent entering of lint.
 During assembly, observe the specified tightening tor que, and apply new gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.
