POWER STEERING FLUID
PFP:KLF20
Checking Fluid LevelEGS001LD
lCheck fluid level with engine stopped.
lMake sure that fluid level is between MIN and MAX.
lFluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:
lThe fluid level should not exceed the MAX line. Excessive
fluid will cause fluid leakage from the cap.
lDo not reuse drained power steering fluid.
lRecommended fluid is Type DEXRONTMIII or equivalent.
Checking Fluid LeakageEGS001LE
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run 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:
Do not hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over-tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer toPS-25, "
POWER STEERING OIL
PUMP".
6. Check steering gear boots for accumulation of fluid, indicating from steering gear.
Air Bleeding Hydraulic SystemEGS001LF
If air bleeding is not complete, the following symptoms can be observed.
lBubbles are created in reservoir tank.
lClicking noise can be heard from oil pump.
lExcessive 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 to full right stop with engine off.
CAUTION:
Turn steering wheel while filling reservoir tank with fluid so as not to lower fluid level below the
MIN line.
2. Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
3. Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Do not 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 while contamination.HOT : Fluid temperature 50 - 80°C (122 - 176°F)
COLD : Fluid temperature 0 - 30°C(32-86°F)

SQUEAK AND RATTLE TROUBLE DIAGNOSES
FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15´25 mm (0.59´0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not available through NISSAN Parts Department, can also be used to repair squeaks
and rattles.
UHMW(TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit.
Note: Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingEIS00CDZ
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. Cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks to
repair the noise.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EDS003IE
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 and SB section of
this Service Manual.
WARNING:
lTo 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 per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo 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
harness connectors.
Precautions for Differential Case Assembly and Differential Lock Control Unit
Replacement
EDS003AG
lWhen replacing differential case assembly or differential lock control unit, check the DIFF LOCK indicator
pattern and adjustment of the position between differential case assembly and differential lock control unit
if necessary.
CHECK DIFF LOCK INDICATOR LAMP
1. Start engine. Run engine for at least 10 seconds.
2. Turn 4WD shift switch to “4LO” and confirm 4LO indicator lamp is turned on. Refer toTF-16, "
4WD SHIFT
SWITCH AND INDICATOR LAMP".
3. Stop vehicle and turn differential lock mode switch to “ON”.
4. Drive vehicle at 7 km/h (4 MPH) or less.
NOTE:
Differential case assembly must be given a rotation from rear left wheel and rear right wheel.
5. Check if DIFF LOCK indicator lamp flashes to turn on.
6. Check if DIFF LOCK indicator lamp and 4LO indicator lamp are changed properly as follows.
lIf each indication and state is OK, rear final drive assembly and differential lock control unit is working cor-
rectly.
lIf each indication and state is NG, rear final drive assembly and differential lock control unit is not working
correctly. Refer toRFD-34, "
METHOD FOR ADJUSTMENT".
