WAR NIN G:
Never get under the vehicle while it is supported only by the jack. Always use safety stands to
support the frame when you have to get under the vehicle.
Place wheel chocks at both front and back of the wheels on the ground.
CAUTION:
All applicable State or Provincial (in Canada) laws and local laws regarding the towing operation
must be obeyed.
It is necessary to use proper towing equipment to avoid possible damage during towing opera-
tion. Towing is in accordance with Towing Procedure Manual at dealer.
Always attach safety chains before towing.
When towing, make sure that the transmission, steering system and powertrain are in good order.
If any unit is damaged, dollies must be used.
Never tow an automatic transmission model from the rear
(i.e., backward) with four wheels on the ground as this may
cause serious and expensive damage to the transmission.
2WD MODELS
NISSAN does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:
When towing with the front wheels on the ground: Turn the
ignition key to the OFF position and move the transmission
selector lever to N (neutral) position, turn the ignition key to
OFF position and secure the steering wheel in a straight
ahead position with a rope or similar device. Never place
the ignition key in the LOCK position. This will result in
damage to the steering lock mechanism.
Observe the following restricted towing speeds and distances.
WAIA0030E
Speed : Below 95 km/h (60 MPH)
Distance : Less than 800 km (500 miles)

4WD MODELS
NISSAN does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:
When towing with the front wheels on the ground or rear
wheels on the ground (If you do not use towing dollies): Set
the free-running hubs to the free position and move the
transfer case shift lever into the “2H” position.
When towing with the front on the ground: Turn the ignition
key to the OFF position and secure the steering wheel in a
straight ahead position with a rope or similar device. Never
place the ignition key in the LOCK position. This will result
in damage to the steering lock mechanism.
Observe the following restricted towing speeds and distances.
Towing Point
CAUTION:
Never tow the vehicle using only the towing points. To avoid
damaging the vehicle body, use proper towing equipment when
towing.
Vehicle Recovery (Freeing a stuck vehicle)EAS00150
Tow chains or cables must be attached only to the main structural members of the vehicle or the
towing hooks (if so equipped). Otherwise, the vehicle body will be damaged.
Use the towing hook (if so equipped) only to free a vehicle stuck in sand, snow, mud, etc. Never
tow the vehicle for a long distance using only the towing hook.
The towing hook is under tremendous force when used to free a stuck vehicle. Never pull the hook
at an angle.
Always pull the cable straight out from the front or rear of the vehicle.
Pulling devices should be routed so they do not touch any part of the suspension, steering, brake,
or cooling systems.
Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
WA RN ING:
Stand clear of a stuck vehicle.
Do not spin your tires at high speed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.Speed : Below 95 km/h (60 MPH)
Distance : Less than 800 km (500 miles)

GENERAL MAINTENANCE
Revision: August 20072004 QX56
GENERAL MAINTENANCEPFP:00000
General MaintenanceELS000ZZ
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owner can perform these
checks and inspections or have their NISSAN dealers perform them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.ItemReference page
TiresCheck the pressure with a gauge at least once a month and always prior to a
long distance trip. Adjust to the specified pressure if necessary. Check carefully
for damage, cuts or excessive wear.—
Wheel lug nutsWhen checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.WT-6, "
Rotation"
WindshieldClean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary.
Tire rotationTires should be rotated every 12,000 km (7,500 miles).WT-6, "
Rotation"
Wheel alignment and
balanceIf the vehicle pulls to either side while driving on a straight and level road, or if
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel
balancing may be needed.WT-5, "Balancing
Wheels", FSU-6, "Front
Wheel Alignment"
Windshield wiper
bladesCheck for cracks or wear if they do not wipe properly.
—
Doors and engine
hoodCheck that all doors and the engine hood operate smoothly as well as the back
hatch. Also make sure that all latches lock securely. Lubricate if necessary.
Make sure that the secondary latch keeps the hood from opening when the pri-
mary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently.MA-30, "
Lubricating
Locks, Hinges and Hood
Latches"
Lamps
Make sure that the head lamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head
lamp aim. Clean the head lamps on a regular basis.LT- 3 1 , "Aiming Adjust-
ment" for US, LT- 4 6 ,

ponents Inspection"
Windshield wiper and
washerCheck that the wipers and washer operate properly and that the wipers do not
streak.—
Windshield defrosterCheck that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner.—
Steering wheelCheck that it has the specified play. Be sure to check for changes in the steering
condition, such as excessive play, hard steering or strange noises.PS-7, "

SeatsCheck seat position controls such as seat adjusters, seat back recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every
position. Check that the head restraints move up and down smoothly and that
the locks (if equipped) hold securely in all latched positions. Check that the
latches lock securely for folding-down rear seat backs.—
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.SB-10, "

Checking Power Steering Fluid and LinesELS0010U
CHECKING FLUID LEVEL
Check the power steering fluid level with the engine off.
Check fluid level on reservoir. Use “HOT” range at fluid tempera-
tures of 50° to 80°C (122° to 176°F). Use “COLD” range at fluid
temperatures of 0° to 30°C (32° to 86°F).
CAUTION:
Do not overfill.
Refer to MA-10, "Fluids and Lubricants" .
CHECKING LINES
Check lines for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.
Checking Axle and Suspension PartsELS0010V
FRONT AND REAR AXLE AND SUSPENSION PARTS
Check front and rear axle and suspension parts for excessive play, cracks, wear or other damage.
Shake each wheel to check for excessive play.
Rotate each wheel to check for abnormal noise.
Check axle and suspension nuts and bolts for looseness.
Check the strut and shock absorber for oil leakage or other damage.
Check suspension ball joints for grease leakage and ball joint dust cover for cracks or other damage.
DRIVE SHAFT
Check the boots and drive shaft for cracks, wear, damage, and
grease leakage.
