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-13, "
Exploded View".
 Check steering gear assembly mounting condition for looseness. Refer to ST-18, "
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. Check the following items when steering wheel play is out of the standard.
 Check backlash for each joint of steering column assembly.
 Check installation condition of steering gear assembly.
NEUTRAL POSITION STEERING WHEEL
1. Check that steering gear assembly, steering column assembly and steering wheel are installed in the cor-
rect position.
2. Perform neutral position inspection after wheel alignment. Refer to FSU-7, "
Wheel Alignment Inspection".
3. Set the vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
4. 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
1. Park the vehicle on a level and dry surface, set parking brake.
2. Tires need to be inflated normal pressure. Refer to WT-5, "
Tire Air Pressure".
3. Start the engine.
4. Bring power steering fluid up to adequate operating temperature.Standard

STEERING WHEEL
5. 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.
6. 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-32, "
Inspection".
RACK SLIDING FORCE
1. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to ST-16, "Exploded
View".
2. Start and run the engine at idle to make sure steering fluid has reached normal operating temperature.
3. While pulling outer socket slowly in ±11.5 mm (±0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
4. If rack sliding force is not within specification, overhaul steering
gear assembly.
FRONT WHEEL TURNING ANGLE
1. Check front wheel turning angle after toe-in inspection. Refer to FSU-7, "Wheel Alignment Inspection".
2. Place front wheels on turning radius gauges and rear wheels on
stands, so that vehicle can be level.
3. Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
4. With the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.Standard

5. Check the following items when turning angle is out of the stan-
dard.
a. Check the neutral position of the rack stroke (L).
b. 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. Standard

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003971959
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 “SRS AIRBAG” and
“SEAT BELT” 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 “SRS AIRBAG”.
 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.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003893541
NOTE:
 Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.
