Explanation of General MaintenanceELS001YB
General MaintenanceELS001YC
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 owners can perform
checks and inspections themselves or they can have their NISSAN dealers do 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 including the spare, at least once a month and always prior
to a long distance trip. Adjust to the specified pressure if necessary. Check care-
fully for damage, cuts or excessive wear.WT-29, "
Tire"
Wheel 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.FSU-6, "Wheel Align-
ment Inspection" and
WT-6, "
Balancing
Wheels"
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 trunk
lid and 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 primary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently.MA-27, "
Lubricating
Locks, Hinges and Hood

quantity when operating the heater or air conditioning.—
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.
Free play: Less than 35 mm (1.38 in)—
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.—

"Checking Clutch Fluid
Level and Leaks"
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 fre-
quent checks of the battery fluid level.—
Engine drive beltsMake 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 turning
off the engine.LU-5, "ENGINE OIL

Automatic tran-
saxle fluid levelCheck the level on the dipstick after putting the selector lever in “P” with the
engine idling.MA-20 and 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-20
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 substances,
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 nor-
mal. If you should notice any leaks or gasoline fumes are evident, check for the
cause and correct it immediately.—
