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
the proper maintenance care. 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 procedures regularly as
prescribed.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, your NISSAN dealer.
Periodic maintenance
The maintenance items listed in this part are
required to be serviced 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 and 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's vehiclesbe-
forethey work on your vehicle, rather than
after they have worked on it.
You can be confident that your NISSAN
dealer's service department performs the
best job to meet the maintenance require-
ments on your vehicle Ð in a reliable and
economical way.
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 smells, 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 repairs are required.
When performing any checks or maintenance
work, closely observe the precautions in the
``Do-it-yourself operations'' section.
OUTSIDE THE VEHICLE
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself operations'' section.
Tires* ÐCheck the pressure with a gauge
periodically when at a service station, in-
cluding the spare, and adjust to the speci-
fied pressure if necessary. Check carefully
for damage, cuts or excessive wear.
Wheel nuts* ÐWhen checking the tires,
make sure no nuts are missing, and check
for any loose nuts. Tighten if necessary.
GENERAL MAINTENANCE

ZX

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 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 engine hood operate prop-
erly. Also ensure that all latches lock se-
curely. Lubricate 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 using road salt or
other corrosive materials, check lubrication
frequently.
Lights* ÐMake sure the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.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.
Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself operations'' section.
Warning lights and chimes ÐMake sure
all warning lights and chimes are operating
properly.
Windshield wiper and washer* ÐCheck
that the wipers and washer operate properly
and that the wipers do not streak.
Windshield defroster ÐCheck that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.
Steering wheel ÐCheck for changes in
the 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 anddown smoothly and the locks hold securely
in all latched positions.
Seat belts ÐCheck that all parts of the seat
belt system (e.g., buckles, anchors, adjust-
ers 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 mats away from the pedal.
Clutch pedal* ÐMake sure the pedal
operates smoothly and check that it has the
proper free travel.
Brakes ÐCheck that the brakes do not pull
the vehicle to one side when applied.
Brake pedal* ÐCheck the pedal for
smooth operation and make sure it has the
proper distance under it when depressed
fully. Check the brake booster function. Be
certain to keep floor mats 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 ``Park'' mecha-
nism ÐOn a fairly steep hill check that your
vehicle is held securely with the selector
lever in the P position without 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 ``*'' is found in the ``Do-it-
yourself operations'' section.
Windshield washer fluid* ÐCheck for
adequate fluid in the tank.
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.
Brake fluid level* ÐMake sure the brake
and clutch fluid level is between the MAX
and MIN lines on the reservoir.Battery* ÐCheck the fluid level in each
cell.
Engine drive belts* ÐMake sure no belt is
frayed, worn, cracked or oily.
Engine oil level* ÐCheck the level after
parking the vehicle on a level spot and
turning off the engine. Wait a few minutes
for the oil to drain back into the oil pan.
Power steering fluid level* and lines Ð
Check the level when the fluid is cold and
the engine is turned off. Check the lines for
proper attachment, leaks, cracks, etc.
Automatic transmission fluid level* Ð
Check the level after putting the selector
lever in P with the engine idling.
Exhaust system ÐMake sure there are no
cracks, holes, loose joints or supports. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected by
a qualified individual. (See the carbon mon-
oxide warning in the ``Starting and driving''
section.)
Underbody ÐThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. Itis very important to remove these sub-
stances, otherwise rust forms on the floor
pan, frame, fuel lines and around the ex-
haust 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 may accu-
mulate. See the ``Appearance and interior
care'' section for additional information.
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.
