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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” 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 “SUPPLEMENTAL RESTRAINT SYSTEM”.

• 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

INFOID:0000000001327424

• Before connecting or disconnecting 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 ignition switch is turned “OFF”.

• When connecting or disconnecting 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 Precaution

INFOID: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 transfer. 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 removal or disassembly. If matching marks are required, be

certain they do not interfere with the function of the parts when applied.

• Check appearance of the disassembled parts for damage, 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.
