GENERAL MAINTENANCE
Revision: October 20052005 QX56
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).BrakesCheck that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
boosterCheck the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Keep the floor
mats away from the pedal.BR-6, "
Inspection and
Adjustment", BR-16,
"On-Vehicle Service"
Parking brakeCheck that the parking brake control has the proper travel and make sure that
the vehicle is held securely on a fairly steep hill when only the parking brake is
applied.PB-3, "On-Vehicle Ser-
vice"
Automatic transmis-
sion “Park” mecha-
nismOn a fairly steep hill check that the vehicle is held securely with the selector
lever in the P position without applying the brakes. — ItemReference page
ItemReference page
Windshield washer
fluidCheck that there is adequate fluid in the tank.
—
Engine coolant levelCheck the coolant level when the engine is cold.MA-13
Radiator and hosesCheck the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation,
deterioration or loose connections.—
Brake fluid levelMake sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoirsMA-28
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN”
lines. Vehicles operated in high temperatures or under severe conditions require
frequent checks of the battery fluid level.—
Engine drive beltMake sure that no belt is frayed, worn, cracked or oily.MA-13
Engine oil levelCheck the level on the dipstick after parking the vehicle on a level spot and turn-
ing off the engine.MA-17
Power steering fluid
level and linesCheck the level on the reservoir with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.MA-29
Automatic transmis-
sion fluid levelCheck the level on the dipstick after putting the selector lever in “P” with the
engine idling.MA-22
Exhaust systemMake sure there are no loose supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it.MA-22
UnderbodyThe underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate.—
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping from the air conditioner after use is
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately.—

Introduction of Periodic MaintenanceELS001BJ
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)ELS001BK
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
Schedule 1ELS001BL
EMISSION CONTROL SYSTEM MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary. [ ]: At the mileage intervals only Schedule 1Follow Periodic Maintenance Schedule 1 if your driving habits frequently includes
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.
Driving in dusty conditions.
Driving on rough, muddy, or salt spread roads.
Towing a trailer or using a car-top carrier.Emission Control Sys-

(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace drive belts if damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, go to the FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.

6. Install the lower glove box in the instrument panel and secure it
with the two hinge pins.
Checking Exhaust SystemELS001BZ
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, loose connections, chafing or deterioration.
Checking A/T FluidELS001C0
1. Warm up the engine.
2. Check for any fluid leaks.
3. Remove the tightening bolt for the ATF level gauge.
4. Before driving, the fluid level can be checked at fluid tempera-
tures of 30° to 50°C (86° to 122°F) using the “COLD” range on
the ATF level gauge as follows:
a. Park the vehicle on a level surface and set the parking brake.
b. Start the engine and move the selector lever through each gear
position. Shift the selector lever into the “P” position.
c. Check the fluid level with the engine idling.
d. Remove the ATF level gauge and wipe it clean with a lint-free
paper.
CAUTION:
When wiping the fluid from the ATF level gauge, always use
a lint-free paper, not a cloth.
e. Re-insert the ATF level gauge into the charging pipe until the
cap contacts the top of the charging pipe as shown.
CAUTION:
To check fluid level, insert the ATF level gauge until the cap
contacts the top of the charging pipe, with the gauge
reversed from the normal inserted position.
f. Remove the ATF level gauge and note the fluid level. If the fluid
level is at low side of range, add fluid to the transmission
through the charging pipe.
CAUTION:
Do not overfill the transmission with fluid.
5. Drive vehicle for approximately 5 minutes in urban areas.

Tire RotationELS001H5
1. Rotate the tires on each side from front to back as shown.
2. Adjust the tire pressure to specification. Refer to WT-34, "
Tire" .
3. After the tire rotation, retighten the wheel nuts after the vehicle
has been driven for 1,000 km (600 miles), and also after a wheel
and tire have been installed such as after repairing a flat tire.
Checking Brake Fluid Level and LeaksELS001CA
Check the brake fluid level in the reservoir tank. It should be
between the “MAX” and “MIN” lines on the reservoir tank.
If the fluid level is extremely low, check the brake system.
If the brake warning lamp comes on when the fluid is at the cor-
rect level, check the brake fluid level switch and the parking
brake switch.
Checking Brake Lines and CablesELS001CB
1. Check the brake lines and hoses for cracks, deterioration, and
other damage. Replace any damaged parts.
CAUTION:
If brake fluid leaks are visible around the brake line joints,
retighten the joint, or replace damaged parts as necessary.
2. Check for brake fluid leaks by fully depressing brake pedal while
engine is running.
Checking Disc BrakeELS001CC
ROTOR
Check the rotor condition for wear or damage. Refer to BR-31,
"Front Disc Brake" , BR-32, "Rear Disc Brake" . Wheel nuts : Refer to WT-6, "
