Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009471810
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 SR 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR 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 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 electric 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 3 minutes before performing any service.
Service Notice or Precautions
INFOID:0000000009471811
• When installing rubber bushings, the final tightening must 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.

• 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.
• Make sure that the cotter pin is installed.
• Check the rear shock absorber for oil leakage or other damage.
• Check the wheelarch height. Refer to
.
• Check the suspension ball joint for grease leakage and the ball
joint dust cover for cracks or other damage.

REAR SHOCK ABSORBER
• Check for uneven operation through a full stroke for both compression and extension. Replace if necessary.
• Check for oil leakage on the welded or gland packing portions. Replace if necessary.
• Check the rear shock absorber for deformation, cracks, or other damage. Replace if necessary.
• Check the piston rod for damage, uneven wear, and distortion. Replace if necessary.

following conditions exist:
- The ball stud is worn.
- The swinging force (A) is out of specification.
- The turning force (B) is out of specification.
- The vertical end play (C) is out of specification.
NOTE:
Before checking specifications, turn the ball joint at least 10 revolu-
tions so the ball joint is properly broken in.
RADIUS ROD
• Check the radius rod for any deformation, cracks, or damage. Replace if necessary.
