PrecautionsADS000K2
CAUTION:
Before starting diagnosis of the vehicle, understand symptoms well. Perform correct and system-
atic operations.
Check for the correct installation status prior removal or disassembly. When matching marks are
required, be sure they do not interfere with the function of the parts they are applied to.
Carry out an overhaul in a clean work place, Using a dust proof room is recommended.
Before disassembly, using steam or white gasoline, completely remove sand and mud from the
exterior the unit, preventing them from entering into the unit during disassembly or assembly.
Check appearance of the disassembled parts for damage, deformation, and abnormal wear. If a
malfunction is detected, replace it with a new one.
Normally replace lock pins, oil seals, and bearings with new ones every times they are removed.
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to out-
side. If tightening sequence is specified, observe it.
Clean and flush the parts sufficiently and blow them dry.
Be careful not to damage the sliding surfaces and mating surface.
When applying sealant, remove the old sealant from the mounting surface; then remove any mois-
ture, oil, and foreign materials from the application and mounting surfaces.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AIS0038A
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.
Service NoticeAIS00389
When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.
Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to oil or
damage them.
Apply sealing compound where necessary when installing parts.
When applying sealing compound, be careful that the sealing compound does not protrude from parts.
When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust pre-
vention measures.
Precautions for WorkAIS0038B
When removing or disassembling each component, be careful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the compo-
nent with a shop cloth or vinyl tape to protect it.
Protect the removed parts with a shop cloth and keep them.
Replace a deformed or damaged clip.
If a part is specified as a non-reusable part, always replace it with new one.
Be sure to tighten bolts and nuts securely to the specified torque.
After re-installation is completed, be sure to make sure each part works normally.
Follow the steps below to clean components.
–Water soluble foul: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the
fouled area.
Then rub with a soft and dry cloth.
–Oily foul: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%), and wipe
the fouled area.
Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub
with a soft and dry cloth.
Do not use organic solvent such as thinner, benzene, alcohol, and gasoline.
For genuine leather seats, use a genuine leather seat cleaner.

Service NoticeADS000RJ
After overhaul refill the transfer with new transfer fluid.
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.
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.
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.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
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.
Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transfer.
