Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010305300
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 SR 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 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 three minutes before performing any service.
Service Notice or Precautions for Steering System
INFOID:0000000009759128
• In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehicle
condition, and then check wheel alignment.
• Observe the following precautions when disassembling.
- Before disassembly, thoroughly clean the outside of the unit.
- Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming
contaminated by dirt or other foreign matter.
- For easier and proper assembly, place disassembled parts in order on a parts rack.
- Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with
their operation.
- Do not reuse non-reusable parts.
- Before assembling, apply the specified grease to the directed parts.
• During quick steering, rasping noise may be heard from around the steering wheel. This is not a malfunction.
The noise is an operating noise of the EPS system under normal conditions. If the rasping noise occurs dur-
ing slow steering, this may not be an operating noise of the system. In this case, it is necessary to find out
the location of the noise and repair, if necessary.
• Do not repeat static steering. (Motor and EPS control unit could be heated.)

CONDITION OF INSTALLATION
• Check installation condition of power steering gear assembly, front suspension, front drive shaft and steering
column.
• Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
• Verify that the power steering gear nuts are tightened to specification. Refer to
.
STEERING WHEEL PLAY
1. Turn tires straight ahead, start engine, then turn steering wheel to the left and right lightly. Measure steer-
ing wheel movement on the outer circumference of the steering wheel when it is turned to the point where
tires start moving.
NEUTRAL POSITION ON STEERING WHEEL
• Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to
23, "Wheel Alignment (Unladen*1)"
.
1. Turn tires straight ahead, check if steering wheel is in the neutral position.
2. If it is not in the neutral position, remove steering wheel and reinstall it correctly.
3. If the neutral position cannot be attained by repositioning the steering wheel two teeth or less on steering
stem, loosen outer socket lock nuts of power steering gear outer sockets, then adjust outer sockets by the
same amount in the opposite direction.
STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Tires need to be inflated to normal pressure. Refer to
.
3. Start engine.
4. Check steering wheel turning force using Tool when steering
wheel has been turned 360
° from the neutral position.
FRONT WHEEL TURNING ANGLE
1. Perform toe-in inspection. Refer to
.
CAUTION:
Perform front wheel turning angle inspection, after toe-in inspection.
