PRECAUTION

PRECAUTIONS

FOR USA AND CANADA

FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR
BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000006843204

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 “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never 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.

FOR USA AND CANADA : Service Notice or Precautions for Steering System

INFOID:0000000006843205

• 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.

- Never reuse non-reusable parts.
- Before assembling, apply the specified grease to the directed parts.

Inspection

INFOID:0000000006843218

NEUTRAL POSITION STEERING WHEEL

Check that steering gear assembly, steering column assembly and steering wheel are installed in the cor-
rect position.

Perform neutral position inspection after wheel alignment. Refer to

FSU-8, "Inspection"

Set the vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.

Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.

STEERING WHEEL TURNING FORCE

Park the vehicle on a level and dry surface, set parking brake.

Tires need to be inflated normal pressure. Refer to

WT-52, "Tire Air Pressure"

Start the engine.

Bring power steering fluid up to adequate operating temperature.

Check steering wheel turning force when steering wheel has
been turned 540

from neutral position.

NOTE:
Multiply the distance (L) from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.

If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump. Regarding relief hydraulic pressure of oil
pump, refer to

ST-106, "Inspection"

RACK SLIDING FORCE

Disconnect lower joint and steering knuckle from steering gear assembly. Refer to

ST-87, "Exploded

View"

Start and run the engine at idle to make sure steering fluid has reached normal operating temperature.

While pulling outer socket slowly in

11.5 mm (

0.453 in) range

from neutral position, make sure rack sliding force is within
specification.

If rack sliding force is not within specification, overhaul steering
gear assembly.

[WITHOUT HEATED STEERING WHEEL]

Place front wheels on turning radius gauges and rear wheels on
stands, so that vehicle can be level.

Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.

With the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.

Check the following items when turning angle is out of the stan-
dard.

Check the neutral position of the rack stroke (L).

Disassemble steering gear assembly to check the cause that
rack stroke is outside of the standard.
• Steering angles are not adjustable. Check steering gear

assembly, steering column assembly and front suspension
components for wear or damage if any of the turning angles are different from the specified value.
Replace any of them, if any non-standard condition exists.
