PERIODIC MAINTENANCEPFP:00026
Introduction of Periodic MaintenanceELS00100
Two different maintenance schedules are provided, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage or time intervals, whichever comes first.
Maintenance For Off-road Driving (4WD only)ELS0012H
After driving the vehicle off-road through sand, mud, or water; more frequent maintenance may be required for
the following items:
Brake pads and rotors
Brake lines and hoses
Rear final drive oil, transmission fluid, and transfer fluid
Steering linkage
Drive shafts
Engine air cleaner filter
In-cabin microfilters

one or more of the following driving conditions:

Repeated short trips of less than 5 miles (8 km).

Repeated short trips of less than 10 miles (16 km) with outside temperatures
remaining below freezing.

Operating in hot weather in stop-and-go “rush hour” traffic.

Extensive idling and/or low speed driving for long distances, such as police,
taxi or door-to-door delivery use.

SAE Viscosity NumberELS00104
GASOLINE ENGINE OIL

SAE 5W-30 viscosity oil is preferred for all temperatures. SAE
10W-30 and 10W-40 viscosity oil may be used if the ambient
temperature is above -18°C (0°F).

Use of 5W-30 viscosity oil will increase fuel economy.
ANTI-FREEZE COOLANT MIXTURE RATIO
The engine cooling system is filled at the factory with a high-quality, long life, year-round, anti-freeze coolant
solution. The anti-freeze solution contains rust and corrosion inhibitors. Therefore, additional cooling system
additives are not necessary.
CAUTION:

When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Anti-freeze
coolant or equivalent with the proper mixture ratio of 50% anti-freeze and 50% demineralized water
or distilled water.

Other types of coolant solutions may damage your cooling system.

5. Install the air cleaner case (upper).
6. Install the air duct and resonator assembly (inlet).
Changing Engine OilELS0010A
WAR NIN G:

Be careful not to burn yourself, as the engine oil is hot.

Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible.
1. Warm up the engine, and check for any oil leaks.
2. Stop the engine and wait for at least 10 minutes.
3. Remove the oil drain plug and oil filler cap to drain the old oil.
4. Install a new washer on the oil drain plug, then install the oil drain plug in the oil pan.
CAUTION:
Clean the drain plug and install with a new washer.
5. Refill the engine with the specified oil.
CAUTION:

Clean the drain plug and install with a new washer.

The refill capacity depends on the oil temperature and drain time. Use the oil capacity value as a
reference and check the oil level using the dipstick when filling the oil.
6. Warm up the engine and check the area around the drain plug and oil filter for any oil leaks.
7. Stop the engine and wait for more than 10 minutes.
8. Check the oil level using the dipstick as shown. Add oil as nec-
essary and install the oil filler cap.
CAUTION:
Do not overfill the engine with oil.
Changing Oil FilterELS0010B
1. Remove the oil filter using Tool.

PRECAUTIONS
Revision: August 20072004 QX56
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS0 02 WC
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 and SB section of this Service Man-
ual.
WAR NIN G:

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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper 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.

Do 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 EIS0 02 WD

Disconnect both battery cables in advance.

Never tamper with or force air bag lid open, as this may adversely affect air bag performance.

Be careful not to scratch pad and other parts.

When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.

When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.

Keep removed parts protected with cloth.

If a clip is deformed or damaged, replace it.

If an unreusable part is removed, replace it with a new one.

Tighten bolts and nuts firmly to the specified torque.

After re-assembly has been completed, make sure each part functions correctly.

Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.

Do not use any organic solvent, such as thinner or benzine.

2. Install the pinion mate shaft into the differential case so that it
meets the lock pin holes.
3. Adjust the clearance between rear face of side gear and thrust
washer by selecting the correct thickness side gear thrust
washer. Refer to RFD-26, "
AVAILABLE SIDE GEAR THRUST
WAS HER S" .
Use two feeler gauges as shown to prevent the side gear from
leaning.
SIDE BEARING PRELOAD
NOTE:
A selection of carrier side bearing adjusting washers is required for completion of this procedure.
1. All parts must be clean. The bearings must be well lubricated
with light oil or DEXRON
TM type automatic transmission fluid.
2. Place the differential case assembly, with the side bearing outer
races installed, into the gear carrier.
3. Insert the left and right side bearing adjusting washers in posi-
tion between the side bearings and the gear carrier as shown.
