Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612930
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:0000000001327424
Before connecting or disconnect ing the AWD control unit har-
ness connector, turn ignition switch “OFF” and disconnect
battery ground cable. Because battery voltage is applied to
AWD control unit even if igni tion switch is turned “OFF”.
When connecting or disconnect ing pin connectors into or
from AWD control unit, take care not to damage pin terminals
(bend or break).
When connecting pin connectors, make sure that there are no
bends or breaks on AWD control unit pin terminal.

Service Notice or PrecautionINFOID:0000000001327425
Do not reuse transfer fluid, once it has been drained.
Check the fluid level or replace the fluid only with the vehicle parked on level ground.
During removal or installation, keep inside of transfer clear of dust or dirt.
Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern. Fit-
ting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause lon-
gitudinal vibration.
Disassembly should be done in a clean work area, it is preferable to work in dustproof area.
Before proceeding with disassembly, thoroughly clean the tr ansfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
Check for the correct installation status prior to remo val or disassembly. If matching marks are required, be
certain they do not interfere with t he function of the parts when applied.
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 transfer is disassembled.
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-
ening sequence is specified, use it.
Observe the specified torque when assembling.
Clean and flush the parts sufficiently and blow-dry them.
Be careful not to damage sliding surfaces and mating surfaces.
Clean innerparts with lint-free cloth or towels. Do not use cotton work gloves and rags to prevent adhering
fibers.
