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*Check 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*When checking the tires,
make sure no nuts are missing, and check
for any loose nuts. Tighten if necessary.
GENERAL MAINTENANCE

ZX

Tire rotation*Tires should be rotated every
7,500 miles (12,000 km).
Wheel alignment and balanceIf the ve-
hicle should pull 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 hoodCheck 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*Make 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 chimesMake sure 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 defrosterCheck that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.
Steering wheelCheck for changes in the
steering conditions, such as excessive free-
play, hard steering or strange noises.
SeatsCheck 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 (if so
equipped) hold securely in all latched posi-
tions.
Seat beltsCheck 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 pedalCheck 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 oper-
ates smoothly and check that it has the
proper free travel.
BrakesCheck that the brakes do not pull
the vehicle to one side when applied.
Brake pedal*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 cer-
tain to keep floor mats away from the pedal.

UNDER THE HOOD AND
VEHICLE
The maintenance items listed here should
be checked periodically (e.g. 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*Check for ad-
equate fluid in the tank.
Engine coolant level*Check the coolant
level when the engine is cold.
Radiator and hosesCheck 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*Make sure the brake and
clutch fluid level is between the ``MAX'' and``MIN'' lines on the reservoir.
Battery*Check the fluid level in each cell.
Engine drive belts*Make sure no belt is
frayed, worn, cracked or oily.
Engine oil level*Check the level after
parking the vehicle on a level spot and
turning off the engine.
Power steering fluid level* and lines
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*
Check the level after putting the selector
lever in P with the engine idling.
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. (See the carbon
monoxide warning in the ``Starting and driv-
ing'' section.)
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 sub-
stances, otherwise rust forms on the floorpan, 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 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
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.

AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioning in your NISSAN ve-
hicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
Nissan A/C system lubricant Type R or
the exact equivalents.
CAUTION
Use of any other refrigerant or lubricant
will cause severe damage and you will
need to replace your vehicle's entire air
conditioning system.
The new refrigerant HFC-134a (R-134a) in
your NISSAN vehicle does not harm the
earth's ozone layer. Although this refriger-
ant does not affect the earth's atmosphere,
certain governmental regulations require
the recovery and recycling of any refrigerant
during automotive air conditioning system
service. Your NISSAN dealer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.Contact your NISSAN dealer when servic-
ing your air conditioning system.
