PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951702
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
General PrecautionsINFOID:0000000009460673
• When installing each rubber part, final tightening must be carried out under unladen condition* with
tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated posi-
tions.
• After installing removed suspensi on parts, check wheel alignment.
• Do not jack up at the trailing arm and lateral link.

General PrecautionsINFOID:0000000009464451
• When installing rubber bushings, the final tightening mu st be carried out under unladen conditions with tires
on ground. Oil might 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. Spare tire, jack, hand tools and mats are in designated positions.
• After servicing suspension parts, be sure to check wheel alignment.
• Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-oiled,
tighten as they are.

PERIODIC MAINTENANCE
REAR SUSPENSION ASSEMBLY
On-vehicle ServiceINFOID:0000000009464454
• Check the suspension parts for excessive play, cracks, wear or damage. Shake each rear wheel to check for
excessive play.
• Retighten all nuts and bolts to the specified torque.
• Check the shock absorber for oil leakage or other damage.
• Check the wheelarch height. Refer to RSU-17, "Wheelarch Height
(Unladen*1)".
InspectionINFOID:0000000009464455
SHOCK ABSORBER ASSEMBLY
• Check for smooth operation through a full stroke for both compression and extension.
• Check for oil leakage on the welded or gland packing portions.
• Check the shock absorber piston r od for cracks, deformation, or other damage and replace if necessary.
SUSPENSION ARMS
• Check the suspension arm for damage, cracks, deformation and replace if necessary.
• Check the rubber bushings for damage, cracks and defo rmation. Replace suspension arm if necessary.
• After installing the radius rod, check the wheel alignment and adjust if necessary. Refer to RSU-17, "Wheel
Alignment (Unladen*)".
FRONT LOWER LINK
• Check the front lower link for any deformation, cracks, or damage and replace if necessary.
UPPER AND LOWER RUBBER SEATS
• Check the upper and lower rubber seats for deterioration, or cracks and replace if necessary.
REAR LOWER LINK AND COIL SPRING
• Check the rear lower link and coil spring for any def ormation, cracks, or other damage and replace if neces-
sary.
STABILIZER BAR
• Check the stabilizer bar and clamps for any deformation, cracks, or damage and replace if necessary.
• Check the rubber bushings for deterioration, or cracks and replace if necessary.
Inspection and AdjustmentINFOID:0000000009464456
Before checking the rear wheel ali gnment, make a preliminary inspection.
• Measure the wheel alignment under unladen conditions. NOTE:
Unladen conditions mean that fuel, engine coolant, and l ubricants are full. That the spare tire, jack, hand
tools, and mats are in their designated positions.
PRELIMINARY INSPECTION
• Check the tires for wear and for improper inflation.
• Check the wheels for deformation, cracks, and ot her damage. Remove the wheel and check the wheel
runout. Refer to WT-53, "Inspection"
.
• Check the rear wheel bearings for looseness.
• Check the rear suspension for looseness.
• Check that the rear shock absorbers work properly.
