Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NHS00073
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 SRS 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 per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceNHS00074
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
Diagnosis sensor unit must always be installed with their arrow marks “ ⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before instal-
lation and replace as required.
The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steer-
ing wheel and column after removal of steering gear.
Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and seat mounted front side air bag module standing with the stud bolt side facing
down.
Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
After air bag inflates, the front instrument panel assembly should be replaced if damaged.
Always replace instrument panel pad following front passenger air bag deployment.
Disposal, recycling, and transportation of air bag modules and seat belt pre-tensioners should be per-
formed in compliance with applicable federal, state and local laws and regulations.
Occupant Classification System PrecautionNHS0009N
Replace occupant classification system control unit and passenger front seat cushion as an assembly.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT

NDS0009M
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

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 SRS 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 per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.
PrecautionsNDS0009N
Before connecting or disconnecting the AWD control unit
harness connector, turn ignition switch “OFF” and discon-
nect 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 termi-
nals (bend or break).
When connecting pin connectors, make sure that there are
no bends or breaks on AWD control unit pin terminal.
Before replacing AWD control unit, perform AWD control
unit input/output signal inspection and make sure whether
AWD control unit functions properly or not. Refer to TF-20,
"AWD Control Unit Input/Output Signal Reference Values" .

PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45
Service Notice or PrecautionsNDS0009O
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.
Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause
longitudinal 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
tightening 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.
