Your new NISSAN has been designed to
have minimum maintenance requirements
with longer service intervals to save you
both time and money. However, some day-
to-day and regular maintenance is essential
to maintain your NISSAN's good mechani-
cal condition, as well as its emission and
engine performance.
It is the owner's responsibility to make sure
the specified periodic maintenance, as well
as general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. You are a vital link in
the maintenance chain.
General maintenance
General maintenance includes those items
which should be checked during normal
day-to-day operation of the vehicle. They
are essential if your vehicle is to continue to
operate properly. It is your responsibility to
perform these maintenance procedures
regularly as prescribed.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, an authorized NISSAN dealer.Periodic maintenance
The maintenance items listed under peri-
odic maintenance are required to be ser-
viced at regular intervals.
However, under severe driving conditions,
additional or more frequent maintenance is
required.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists who are kept up-to-date with the
latest service information through technical
bulletins, service tips, and in-dealership
training programs. They are completely
qualified to work on NISSAN vehiclesbe-
forethey work on your vehicle, rather than
after they have worked on it.
You can be confident that an authorized
NISSAN dealer's service department per-
forms the best job to meet the maintenance
requirements on your vehicle Ð in a reliable
and economical way.During the normal day-to-day operation of
the vehicle, general maintenance should be
performed regularly as prescribed in this
section. If you detect any unusual sounds,
vibrations or smells, be sure to check for the
cause or have an authorized NISSAN
dealer do it promptly. In addition, you should
notify an authorized NISSAN dealer if you
think repairs are required.
When performing any checks or maintenance
work, closely observe the precautions in the
``Do-it-yourself'' section of this manual.

for damage, cuts or excessive wear.
Wheel nuts* ÐWhen checking the tires,
make sure no wheel nuts are missing, and
check for any loose wheel nuts. Tighten if
necessary.
Tire rotation* ÐTires should be rotated
every 7,500 miles (12,000 km).
Wheel alignment and balance ÐIf the
vehicle should pull to either side while driv-
ing on a straight and level road, or if you
detect uneven or abnormal tire wear, there
may be a need for a wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
Windshield wiper blades* ÐCheck for
cracks or wear if they do not wipe properly.
Doors and engine hood ÐCheck that all
doors and the hood operate properly. Also
ensure that all latches lock securely. Lubri-
cate hinges, latches, rollers and links if
necessary. Make sure the secondary latch
keeps the hood from opening when the
primary latch is released.
When driving in areas that use road salt orother corrosive materials, check lubrication
frequently.
Lights* ÐMake sure the headlamps, stop-
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlamp aim.
INTERIOR MAINTENANCE
The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc.
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself'' section of this manual.
Warning lights and chimes ÐMake sure
all warning lights and chimes are operating

Steering wheel ÐCheck for changes inthe steering conditions, such as excessive
freeplay, hard steering or strange noises.
Seats ÐCheck seat position controls such
as seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints move up and
down smoothly and the locks hold securely
in all latched positions.
Seat belts ÐCheck that all parts of the seat
belt system (For example buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Accelerator pedal ÐCheck the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Clutch pedal* ÐMake sure the pedal
operates smoothly and check that it has the
proper free travel.

has the proper distance under it when de-
pressed fully. Check the brake booster func-
tion. Be certain to keep the floor mat away
from the pedal.
Parking brake* ÐCheck that the lever has
the proper travel and confirm that your
vehicle is held securely on a fairly steep hill
with only the parking brake applied.
Automatic transmission ``P position''
mechanism ÐOn a fairly steep hill check
that your vehicle is held securely with the
selector lever in the P (Park) position with-
out applying any brakes.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically, such as each time
you check the engine oil or refuel.
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself'' section of this manual.
Windshield washer fluid* ÐCheck for
adequate fluid in the tank.
Engine oil level* ÐCheck the level after
parking the vehicle on a level surface, with
the engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Brake and (if so equipped) clutch fluid
levels* ÐMake sure the brake and clutch
fluid level is between the MIN and MAX lines
on each reservoir.
Power steering fluid level* and lines Ð
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Automatic transmission fluid level* Ð
Check the level after putting the shift selec-
tor lever in P (Park) with the engine idling at
operating temperature.
Engine coolant level* ÐCheck the cool-
ant level when the engine is cold.
Radiator and hoses ÐCheck the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts* ÐMake sure the drive
belts are not frayed, worn, cracked or oily.
Battery* ÐCheck the fluid level in each
cell.
Exhaust system ÐMake sure there are no
cracks, holes, loose joints or supports. If the
sound of the exhaust seems unusual orthere is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected by
an authorized NISSAN dealer. See the car-
bon monoxide warning in the ``Starting and
driving'' section of this manual.
Underbody ÐThe 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, from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, especially those areas
where mud and dirt may have accumulated.
See the ``Appearance and care'' section of
this manual.
Fluid leaks ÐCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for awhile. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately by
an authorized NISSAN dealer.
