PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NIS0025I
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.
WAR NING :
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 NoticeNIS0025J
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 WorkNIS0025K
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 check that 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.

PRECAUTIONS
Revision: 2006 January2006 M35/M45
Service Notice or PrecautionsNDS000D5
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.

DRAINING
1. Run the vehicle to warm up the transfer unit sufficiently.
2. Stop the engine, and remove the drain plug to drain the transfer
fluid.
CAUTION:
When draining fluid, protect exhaust tube flange with cover.
3. Apply sealant to drain plug. Install drain plug on transfer and
tighten to the specified torque. Refer to TF-45, "
COMPO-
NENTS" .
Use Genuine Silicone RTV or equivalent. Refer to GI-48,
"Recommended Chemical Products and Sealants" .
CAUTION:
Remove old sealant adhering to mounting surfaces. Also
remove any moisture, oil, or foreign material adhering to application and mounting surfaces.
FILLING
1. Remove filler plug and add transfer fluid until fluid level reaches
the specified limit near filler plug mounting hole.
CAUTION:
Carefully fill the fluid. (Fill up for approx. 3 minutes.)
2. Leave the vehicle for 3 minutes, and check the fluid level again.
3. Set a new gasket onto filler plug and install it on transfer and
tighten to the specified torque. Refer to TF-45, "
COMPO-
NENTS" .
CAUTION:
Do not reuse gasket.
InspectionNDS000DA
FLUID LEAKAGE AND FLUID LEVEL
1. Check if fluid is leaking from transfer or around it.
2. Check fluid level from filler plug mounting hole as shown in the
figure.
CAUTION:
Never start engine while checking fluid level.
3. Before installing filler plug, set a new gasket. Install filler plug on
transfer and tighten to the specified torque. Refer to TF-45,
"COMPONENTS" .
CAUTION:
Do not reuse gasket.

AWD SYSTEM
Revision: 2006 January2006 M35/M45
AWD SYSTEMPFP:41650
Power Transfer DiagramNDS000DB
System DescriptionNDS000DC
DESCRIPTION
Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close
to rear-wheel drive.
Sensor inputs determine the vehicle's turning condition, and in response tight cornering/braking are con-
trolled by distributing optimum torque to front wheels.
NOTE:
When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becomes too high and AWD warning lamp flashes rapidly.
(When AWD warning lamp flashes, vehicle changes to rear-wheel drive conditions.) Also, optional distri-
bution of torque sometimes becomes rigid before lamp flashes rapidly, but it is not malfunction.
If AWD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop
and AWD system will be restored.
When driving, AWD warning lamp may flash slowly if there is a significant difference in diameter of the
tires. At this time, vehicle performance is not fully available and cautious driving is required. (Continues
until engine is turned OFF.)
If the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.
When the difference of revolution speed between the front and rear wheel the shift occasionally changes
to direct 4-wheel driving conditions automatically. This is not malfunction.
