PRECAUTIONS
Revision: 2005 July 2005 FX
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AIS003CB
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.
PrecautionsAIS003CC

Disconnect both battery cables in advance.

Disconnect air bag system line in advance.

Never tamper with or force air bag lid open, as this may adversely affect air bag performance.

Be careful not to scratch pad and other parts.

When removing or disassembling any part, be careful not to damage or deform it. Protect parts, which
may get in the way with cloth.

When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.

Keep removed parts protected with cloth.

If a clip is deformed or damaged, replace it.

If an unreusable part is removed, replace it with a new one.

Tighten bolts and nuts firmly to the specified torque.

After re-assembly has been completed, make sure each part functions correctly.

Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.

Do not use any organic solvent, such as thinner or benzine.

Tire RotationALS000HB

After rotation the tires, adjust the tire pressure.

Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:

Do not include the T-type spare tire when rotating the tires.

When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
Checking Brake Fluid Level and LeaksALS000FQ

If fluid level is extremely low, check brake system for leaks.
Checking Brake Lines and CablesALS000FR

Check brake fluid lines and parking brake cables for improper
attachment, leaks, chafing, abrasions, deterioration, etc.
Changing Brake FluidALS000FS
1. Drain brake fluid from each bleed valve.
2. Refill until new brake fluid comes out from each bleed valve. Use same procedure as in bleeding hydraulic system to refill
brake fluid.
Refer to BR-10, "
Bleeding Brake System" .

Refill with recommended Genuine Nissan Super Heavy Duty
Brake Fluid or equivalent DOT 3 (US FMVSS No. 116).
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas. Tightening torque of wheel nut

Revision: 2005 July 2005 FX

As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.

Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
CAUTION:
Do not disassemble joints.
INSTALLATION
Note the following, install in the reverse order of removal.

Align matching marks to install propeller shaft to final drive com-
panion flange, and then tighten to specified torque. Refer to PR-
4, "Components" .
CAUTION:
Do not reuse the bolts.

After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from
final drive or transfer. Reinstall companion flange after rotating it
by 90, 180, 270 degrees. Then perform driving test and check
propeller shaft vibration again at each point. Propeller shaft runout measuring point

INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Avoid damaging the rebro joint boot, protect it with a shop towel or equivalent.

Align matching marks to install propeller shaft to final drive and transfer (AWD models only) companion
flanges, and then tighten to specified torque. Refer to PR-8, "
Components" .

Install center bearing mounting bracket (Upper) with its arrow
mark facing forward.

Adjust position of mounting bracket sliding back and forth to pre-
vent play in thrust direction of center bearing insulator. Install
bracket to vehicle.

After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from
final drive. Reinstall companion flange after rotating it by 60,
120, 180, 240, 300 degrees. Then perform driving test and
check propeller shaft vibration again at each point.

If propeller shaft or final drive has been replaced, connect them
as follows:
1. Install the propeller shaft while aligning its matching mark A with the matching mark B on the joint as close as possible.
2. Tighten the joint bolts to the specified torque. Refer to PR-8,
"Components" .
CAUTION:
Do not reuse the bolts, nuts and washers.
