PRECAUTION

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000007540173

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.

Service Notice or Precautions for Steering System

INFOID:0000000007540174

• 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.

FLUID LEVEL

1.

Check fluid level with engine stopped.

2.

Ensure that fluid level is between MIN and MAX.

3.

Fluid levels at HOT and COLD are different. Do not confuse
them.

CAUTION:

• The fluid level should not exceed the MAX line. Excessive fluid causes fluid leakage from the

cap.

• Never reuse drained power steering fluid.

FLUID LEAKAGE

Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.

1.

Run the engine until the fluid temperature reaches 50 to 80

°

C

(122 to 176

°

F) in reservoir tank, and keep engine speed idle.

2.

Turn steering wheel several times from full left stop to full right
stop.

3.

Hold steering wheel at each lock position for five seconds and
carefully check for fluid leakage.

CAUTION:

Never hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that power steer-
ing oil pump assembly may be damaged.)

4.

If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not overtighten con-
nector as this can damage O-ring, washer and connector.

5.

If fluid leakage from oil pump is noticed, check oil pump.

6.

Check steering gear boots for accumulation of fluid leaked from steering gear.

AIR BLEEDING HYDRAULIC SYSTEM

If air bleeding is not complete, the following symptoms can be observed.
• Bubbles are created in reservoir tank.
• Clicking noise can be heard from oil pump.
• Excessive buzzing in the oil pump.

NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of the
system.

1.

Turn steering wheel several times from full left stop to full right stop with engine off.

CAUTION:

HOT (A)

: Fluid temperature 50 – 80

°

C (122 – 176

°

F)

COLD (B)

: Fluid temperature 0 – 30

°

C (32 – 86

°

F)

Recommended fluid

Refer to 

MA-16, "FOR NORTH 

AMERICA : Fluids and Lubri-
cants"

 (For North America), 

MA-

17, "FOR MEXICO : Fluids and 
Lubricants"

 (For Mexico).

< PERIODIC MAINTENANCE >

[WITHOUT HEATED STEERING WHEEL]

POWER STEERING FLUID

Fill reservoir tank with a sufficient amount of fluid so that fluid level is not below the MIN line while
turning steering wheel.

2.

Start the engine and hold steering wheel at each lock position for 3 second at idle to check for fluid leak-
age.

3.

Repeat step 2 above several times at approximately 3 second intervals.

CAUTION:

Never hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-
bility that oil pump may be damaged.)

4.

Check fluid for bubbles and white contamination.

5.

Stop the engine if bubbles and white contamination do not drain out. Perform step 2 and 3 above after
waiting until bubbles and white contamination drain out.

6.

Stop the engine, and then check fluid level.

STEERING WHEEL AXIAL END PLAY

1.

Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.

2.

Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.

3.

Check the following items when steering wheel axial end play is out of the standard.
• Check the steering column assembly mounting condition. Refer to 

ST-79, "Exploded View"

.

• Check steering gear assembly mounting condition for looseness. Refer to 

ST-85, "Exploded View"

.

STEERING WHEEL PLAY

1.

Turn steering wheel so that front wheels come to the straight-ahead position.

2.

Start the engine and lightly turn steering wheel to the left and right until front wheels start to move.

3.

Measure steering wheel movement on the outer circumference.

4.
