TEMPERATURE CONDITIONS
FOR CHECKING ATF
cThe fluid level should be checked using
the HOT range on the dipstick after the
following conditions have been met:
Ð The engine should be warmed up to
operating temperature.
Ð The vehicle should be driven at least 5
minutes.
Ð The ATF should be warmed to between
122 and 176ÉF (50 and 80ÉC).

nical and consumer information'' section of
this manual.
WARNING
Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake and clutch
systems. The use of improper fluids
can damage the brake system and af-
fect the vehicle's stopping ability.
CAUTION

cKeep the battery surface clean and dry.
Any corrosion should be washed off with
a solution of baking soda and water.
cMake certain the terminal connections
are clean and securely tightened.

If the vehicle is not to be used for 30 days
or longer, disconnect the negative (þ) bat-
tery terminal cable to prevent discharge.
WARNING

or electrical sparks. Hydrogen gas
generated by battery action is explo-
sive. Do not allow battery fluid to
contact your skin, eyes, fabrics, or
painted surfaces. After touching a
battery or battery cap, do not touch
or rub your eyes. Thoroughly wash
your hands. If the acid contacts your

ber of clicks is out of the range listed above,
see an authorized NISSAN dealer.With the engine running, check distance A
between the upper surface of the pedal and

PARKING BRAKE CHECK BRAKE PEDAL

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front disc-type brakes self-adjust every
time the brake pedal is applied. The rear
drum-type brakes on two-wheel drive trucks
self-adjust every time the parking brake is
applied. The rear drum-type brakes on four-
wheel drive trucks self-adjust every time the
brake pedal is applied. If the brake pedal
goes down farther than normal, it may be
due to a lack of adjustment of the rear drum
brakes. Apply the parking brake several
times.
WARNING
If the brake pedal height does not re-
turn to normal, see an authorized NIS-
SAN dealer and have it checked.
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 brakeschecked as soon as possible if the wear
indicator sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal 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 an authorized NIS-
SAN dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance Schedule'' section of this
manual.Check the brake booster function with the
following steps:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedal
application to the next, continue on to
next step.
2. While depressing the brake pedal, start
the engine. The pedal height should drop
a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height
should not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it
off. Depress the brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, have
the brakes checked by an authorized NIS-
SAN dealer.

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
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
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 in this section are re-
quired to be serviced at regular intervals.
However, under severe driving conditions,
additional 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
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists who 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 vehicles
beforethey 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 economic 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 that repairs are required.
When performing any checks or mainte-
nance work, closely observe the precau-
tions 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 ``*'' is found in the ``Do-it-
yourself'' section of this manual.
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
