Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951759
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.
ServiceINFOID:0000000009463063
• Do not use electrical test equipment to check SRS ci rcuits unless instructed to in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least three
minutes.
For approximately three minutes after the cables are remo ved, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least three minutes
have passed.
• Diagnosis sensor unit must always be installed with their arrow marks “ ⇐” pointing towards the front of the
vehicle for proper operation. Also chec k diagnosis sensor unit for cracks, deformities or rust before installa-
tion and replace as required.
• The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steering
wheel and column after removal of steering gear.
• Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side facing upward and seat mounted front side air bag m odule standing with the stud bolt side facing down.
• Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
• After air bag inflates, the instrument panel assembly should be replaced if damaged.
• Always replace instrument panel pad following front passenger air bag deployment.
Precaution for WorkINFOID:0000000009463065
• When removing or disassembling each component, be careful not to damage or deform it. If a component may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a s hop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.

FLUID LEVEL
Check power steering fluid level at the scale on reservoir tank cap
indicator.
• Check power steering fluid level with engine stopped and the fluid temp between 0 – 30 ° C (32 – 86 ° F).
• Power steering fluid level should be between the hatching area of the indicator on the power steering reservoir tank cap.
CAUTION:
• Do not overfill.
• Do not reuse used power steering fluid.
• Recommended power steering fluid is Genuine NISSAN E-
PSF or equivalent. Refer to MA-11, "FOR USA AND CANADA :
Fluids and Lubricants".
FLUID LEAKAGE
Check the power steering hydraulic system for leaks, cracks, dam-
age, loose connections, chafing or det erioration. Repair or replace
as necessary.
1. Start engine and allow engine to idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. Damage to power steering oil pump may
occur.
4. If power steering fluid leakage at connections is noticed, loosen flare nut and retighten.
CAUTION:
Do not over tighten flare nut as damage to O-ring and connection can occur.
5. If power steering fluid leakage from the power steer ing oil pump is noticed, repair connection or replace
power steering oil pump. Refer to ST-15, "Inspection"
.
6. Check steering gear boots for accumulation of power st eering fluid. Power steering fluid indicates a leak
from the power steering gear, replace as necessary. Refer to ST-36, "Removal and Installation"

• Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
25, "Wheel Alignment (Unladen*1)".
1. Turn tires straight ahead, check if st eering wheel is in the neutral position.
2. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot be attained by repositi oning the steering wheel two teeth or less on steering
stem, loosen tie-rod lock nuts of power steering gear outer sockets, then adjust tie-rods by the same
amount in the opposite direction.
STEERING WHEEL TURNING FORCE
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to operating temperature.
