PRECAUTIONS

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BIS0010L
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. Information necessary to service the system safely is included in the SRS and SB section 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 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 BIS0010M

Disconnect both battery cables in advance.

Do not 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.

PRECAUTIONS

PRECAUTIONSPFP:00001
CautionBES0003W

When installing rubber bushings, final tightening must be performed under unladen conditions with tires
on ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
–Unladen conditions mean that fuel, engine coolant and lubricant are full. A spare tire, a jack, hand tools
and mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Self-locks nut are not reusable. Always use new ones when installing. Since new self-lock nut are pre-
oiled, tighten as they are.

On-Vehicle Inspection BES00040
Make sure that the mounting conditions (looseness, back lash) of each components and component status
(wear, damage) are normal.
INSPECTION OF SUSPENSION ARM BALL JOINT END PLAY
Measure axial end play by placing an iron pry bar or a similar item between suspension arm and axle housing
prying up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage installation position by applying excessive
force.
SHOCK ABSORBER INSPECTION
Check for oil leakage, damage, and breakage of installation positions.
Wheel Alignment InspectionBES00041
DESCRIPTION
Measure the wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” mean that fuel, engine coolant, and lubricant are full. A spare tire, a jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
1. Check tires for improper air pressure and wear.
2. Check road wheels for runout. Refer to WT-3, "
ROAD WHEEL" .
3. Check wheel bearing axial end play. Refer to RAX-3, "
WHEEL BEARING INSPECTION" .
4. Check suspension arm ball joint axial end play. Refer to RSU-11, "
Ball Joint Inspection" .
5. Check shock absorber operation.
6. Check each mounting point of axle housing and suspension for looseness and deformation.
7. Check each link, arm, and member for cracks, deformation, and other damage.
8. Check vehicle height (posture).
CAMBER INSPECTION

Measure camber of both right and left wheels with a suitable
alignment gauge.

Adjust in accordance with the following procedures.

If camber is not within the specification, adjust by turning the
adjusting bolt of front lower link.
NOTE:
After adjusting camber, be sure to check toe-in.Axial end play : 0 mm (0 in)
Camber : Refer to RSU-18, "
SERVICE DATA AND
SPECIFICATIONS (SDS)" .
