After wiper blade replacement, return
the wiper arm to its original position.
Otherwise it may be damaged when the
engine hood is opened.
Make sure the wiper blade contacts the
glass. Otherwise, the arm may be dam-
aged from wind pressure.
If you wax the surface of the hood, be
careful not to let wax get into the washer
nozzle. This may cause clogging or im-
proper windshield washer operation. If wax
gets into the nozzle, remove it with a needle
or small pin.Pull the parking brake lever up. If the number
of clicks is out of the range as listed above, see
your NISSAN dealer.

Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indi-
cator sound is heard.
Under some driving or climate conditions, oc-
casional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does not
affect the function or performance of the brake
system.
The rear drum brakes (if so equipped) do not
have audible wear indicators. Should you ever
hear an unusually loud noise from the rear
drum brakes, have them inspected as soon as
possible by your NISSAN dealer.
Proper brake inspection intervals shouldbe followed.For more information regarding
brake inspections, see the appropriate main-
tenance schedule information in the ªMainte-
nance Scheduleº section of this manual.

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 mechanical condition, as
well as its emission and engine performance.
It is the owner's responsibility to make sure
that the specified 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 es-
sential 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, ad-
ditional or more frequent maintenance will be
required.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the sys-
tems checked and tuned by an authorized
NISSAN dealer.
NISSAN technicians are well-trained special-
ists and are kept up to date with the latest
service information through technical bulletins,
service tips, and in-dealership training pro-
grams. They are completely qualified to work
on NISSAN's vehicles before they work on
your vehicle, rather than after they have
worked on it.
You can be confident that your NISSAN deal-
er's service department performs the best job
to meet the maintenance requirements on your
vehicle Ð in a reliable and economic 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
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, closely observe the precautions in the
ªDo-it-yourself operationsº section.
Additional information on the following
items with ª*º is found in the ªDo-it-
yourself operationsº section.
OUTSIDE THE VEHICLE
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.

Wheel alignment and balanceIf the vehicle
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 properly. Also
ensure that all latches lock securely. Lubricate
hinges, latches, rollers and links if necessary.
Make sure that 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 fre-
quently.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.
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 buzzers/chimesMake
sure that all warning lights and buzzers/chimes
are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and
that the wipers do not streak.

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 en-
sure they operate smoothly and that all latches
lock securely in every position. Check that the
head restraints move up and down smoothlyand that the locks (if so equipped) hold se-
curely in all latched positions.

system (e.g. buckles, anchors, adjusters 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 operates
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 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 certain
to keep floormats 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.
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 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, deformation, rot or
loose connections.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
ªMAXº and ªMINº lines on the reservoir.
Battery*Check the fluid level in each cell. It
should be between the ªMAXº and ªMINº lines.
Engine drive belts*Make sure that 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. (Be sure to wait a few minutes to allowthe oil to drain back into the sump.)
Power steering fluid level* and linesCheck
the level when the fluid is cold and the engine
is turned off. Check the lines for proper attach-
ment, leaks, cracks, etc.
Automatic transmission fluid level*Check
the level after putting the selector lever in ªPº
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 monox-
ide warning in the ªStarting and drivingº sec-
tion)
UnderbodyThe 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. See the ªAppearance and Interior
Careº section for additional information.
Fluid leaksCheck under the vehicle for fuel,
oil, water or other fluid leaks after the vehiclehas 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.
