During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have
your NISSAN dealer do it promptly. In addition,
you should notify your NISSAN dealer if you
think that repairs are required.
When performing any checks or maintenance
work, see ªMaintenance precautionsº in the ª8.
Do-it-yourselfº section.EXPLANATION OF MAINTENANCE
ITEMSAdditional information on the following
items with ª*º is found in the ª8. Do-it-
yourselfº section.Outside the vehicleThe maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Tires*:Check the pressure with a gauge pe-
riodically when at a service station, including
the spare, and adjust to the specified pressure
if necessary. Check carefully for damage, cuts
or excessive wear.
Wheel nuts*:When checking the tires, make
sure no nuts are missing, and check for anyloose nuts. Tighten if necessary.
Tire rotation*:Tires should be rotated every
7,500 miles (12,000 km).
Wheel alignment and balance:If 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 alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
Windshield wiper blades*:Check for cracks
or wear if they do not wipe properly.
Doors and engine hood:Check that all doors
and the engine hood operate smoothly as well
as the trunk lid or back hatch. Also make sure
that all latches lock securely. Lubricate if nec-
essary. 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 lubrication fre-
quently.
Inside the vehicleThe maintenance items listed here should be
checked on a regular basis, such as whenperforming periodic maintenance, cleaning the
vehicle, etc.
Lights*:Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Warning lights and chimes:Make sure that
all warning lights and chimes are operating
properly.
Windshield wiper and washer*:Check that
the wipers and washer operate properly and
that the wipers do not streak.
Windshield defroster:Check that the air
comes out of the defroster outlets properly and
in good quantity when operating the heater or
air conditioner.
Steering wheel:Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Seats:Check seat position controls such as
seat adjusters, seatback recliner, etc. to en-
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.
Seat belts:Check that all parts of the seat belt

ers and retractors) operate properly and
smoothly, and are installed securely. Check
the belt webbing for cuts, fraying, wear or
damage.
Accelerator pedal:Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mats away from the pedal.
Clutch pedal*:Make sure the pedal operates
smoothly and check that it has the proper free
play.
Brakes:Check that the brakes do not pull the
vehicle to one side when applied.
Brake pedal and booster*:Check the pedal
for smooth operation and make sure it has the
proper distance under it when depressed fully.
Check the brake booster function. Be sure to
keep floor mats away from the pedal.
Parking brake*:Check that the lever 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.
Automatic transaxle P (Park) position
mechanism:On a fairly steep hill check that
the vehicle is held securely with the selector
lever in the P (Park) position without applying
any brakes.
Under the hood and the vehicleThe maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Windshield washer fluid*:Check that there
is adequate fluid in the tank.
Engine coolant level*:Check the coolant
level when the engine is cold.
Radiator and hoses:Check 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, dete-
rioration or loose connections.
Brake and clutch fluid levels*:Make sure
that the brake and clutch fluid levels are be-
tween the MAX and MIN lines on the reservoir.
Battery*:Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Engine drive belts*:Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*:Check the level on the
dipstick after parking the vehicle on a level
spot and turning off the engine.
Power steering fluid level* and lines:Check
the level in the reservoir tank with the engineoff. Check the lines for proper attachment,
leaks, cracks, etc.
Automatic transaxle fluid level*:Check the
level on the dipstick after putting the selector
lever in P (Park) position with the engine idling.
Exhaust system:Make 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. (See ªPrecautions when
starting and drivingº in the ª5. Starting and
drivingº section for exhaust gas (carbon mon-
oxide).)
Underbody:The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
ªCleaning exteriorº in the ª7. Appearance and
careº section.
Fluid leaks:Check 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

When planning to travel in another country,
you should first find out if the fuel available is
suitable for your vehicle's engine.
Using fuel with too low an octane rating may
cause engine damage. All gasoline vehicles
must be operated with unleaded engine gaso-
line. Therefore, avoid taking your vehicle to
areas where appropriate fuel is not available.
When transferring the registration of your
vehicle to another country, state, province
or district,it may be necessary to modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ.
When any vehicle is to be taken into an-
other country, state, province or district
and registered, its modifications, transpor-
tation, and registration are the responsibil-
ity of the user. NISSAN is not responsible
for any inconvenience that may result.

ceeded. If GVWR is exceeded, remove
cargo as necessary. If either the front or
rear GAWR is exceeded, shift the load or
remove cargo as necessary.
LOADING TIPSIThe GVW must not exceed GVWR or
GAWR as specified on the F.M.V.S.S. cer-
tification label.
IDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
WARNING
IProperly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
IDo not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts on
your vehicle can break, or it can
change the way your vehicle handles.
This could result in loss of controland cause personal injury.
IOverloading can shorten the life of
your vehicle. Failures caused by
overloading are not covered by your
warranty.
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer will place addi-
tional loads on your vehicle's engine, drive
train, steering, braking and other systems.
Information on trailer towing ability and the
special equipment required should be ob-
tained from your Nissan dealer. He can obtain
