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.
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 an ``*'' is found in the ``Do-it-
yourself'' section of this manual.
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 wheel nuts are missing, and

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 (Park) position without apply-
ing 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 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 and (if so equipped) clutch fluid
level's* ÐMake sure the brake and clutch
fluid levels are between the MIN and MAX
lines on each reservoir.
Battery* ÐCheck the fluid level in each
cell.
Engine drive belts* ÐMake sure the drive
belts are not frayed, worn, cracked or oily.
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.
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 selector
lever in P (Park) with the engine idling at
operating temperature.
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
an authorized NISSAN dealer. (See thecarbon 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 accumulate.
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.
