IKeep the battery surface clean and dry. Any
corrosion should be washed off with a
solution of baking soda and water.
IMake certain the terminal connections are
clean and securely tightened.
IIf the vehicle is not to be used for 30 days or
longer, disconnect the (Ð) negative battery
terminal cable to prevent discharge.
WARNING
IDo not expose the battery to flames
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 eyes,
skin or clothing, immediately flush
with water for at least 15 minutes and
seek medical attention.
IWhen working on or near a battery,
always wear suitable eye protection
and remove all jewelry.IBattery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after han-
dling.
IKeep the battery out of the reach of
children.
IDo not operate the vehicle if the fluid
in the battery is low. Low battery fluid
can cause a higher load on the bat-
tery which can generate heat, reduce
battery life, and in some cases lead to
an explosion.
JUMP STARTINGIf jump starting is necessary, see ªJump start-
ingº in the ª6. In case of emergencyº section. If
the engine does not start by jump starting, the
battery may have to be replaced. Contact your
NISSAN dealer.Check the fluid level in each cell. It should be
between the MAX. and MIN. lines.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening.Do not overfill.
1. Remove the cell plugs using a suitable tool.
2. Add distilled water up to the MAX. level.
If the side of the battery is not visible, the
electrolyte level can be checked through
each filler opening as illustrated.
3. Tighten cell plugs.

under severe conditions require frequent
checks of the battery fluid level.
WARNING
Be sure the ignition key is in the OFF or
LOCK position. The engine could rotate
unexpectedly.
1. Visually inspect each belt for signs of un-
usual wear, cuts, fraying oil adhesion or
looseness. If the belt is in poor condition or
loose, have it replaced or adjusted by your
NISSAN dealer.
2. Have the belts checked regularly for condi-tion and tension.

REPLACING SPARK PLUGS
WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket toremove the spark plugs. An incorrect
socket can cause damage the spark
plugs.
Platinum-tipped spark plugsIt is not necessary to replace the platinum-
tipped spark plugs as frequently as the con-
ventional type spark plugs since they will last
much longer. Follow the maintenance sched-
ule, but do not reuse them by cleaning or
regapping.
If replacement is required, see your NISSAN
dealer for servicing.
Always replace with recommended
platinum-tipped spark plugs.The filter element should not be cleaned and
reused as it is given a special treatment. We
recommended it be replaced according to the
maintenance intervals. See ªPeriodic mainte-
nanceº shown in a separate maintenance
booklet for maintenance intervals. When re-
placing the filter, wipe the inside of the air
cleaner housing and the cover with a damp
cloth.

cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful working on the engine with the air
cleaner removed.
INever pour fuel into the throttle body
or attempt to start the engine with the
air cleaner removed. Doing so could
result in serious injury.
CLEANINGIf your windshield is not clear after using the
windshield washer of if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form when
rinsing with clear water.
Clean the blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blade with clear water. If
your windshield is still not clear after cleaningthe blades and using the wiper, replace the
blades.
REPLACINGReplace the wiper blades if they are worn.
1. Pull the wiper arm.
2. Push the lock pin, then remove the wiper
blade.
3. Insert the new wiper blade to the wiper arm
until a click sounds.

CHECKING BRAKE PEDALWith the engine running, check distance A
between the upper surface of the pedal and
the dash lower panel.
Distance A
M/T models
2-1/2 in (65 mm) or more
A/T models
2-3/4 in (70 mm) or more
If it is out of the range shown above, see your
NISSAN dealer.
Self-adjusting brakesYour vehicle is equipped with self-adjusting
brakes.
The front and rear brakes self-adjust every
time the brake pedal is applied.
WARNING
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.Brake pad wear indicatorsThe 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 should
be followed.For additional information, see
ªPeriodic maintenanceº shown in a separate
maintenance booklet for maintenance inter-
vals.
BRAKE BOOSTERCheck 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) re-
mains the same from one pedal application
to the next, continue on to the 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 decrease gradu-
ally with each depression as the vacuum is
released from the booster.
If the brakes do not operate properly, have the
brake checked by your NISSAN dealer.
CHECKING CLUTCH PEDALPress the pedal by hand and be sure the free
travel is within the above limit. If free travel is
out of the range shown above, see your
NISSAN dealer.

IHigh pressure halogen gas is sealed
inside the halogen bulb. The bulb
may break if the glass envelope is
scratched or the bulb is dropped.
IWhen handling the bulb, do not touch
the glass envelope.Removing the headlight bulb1. Disconnect the battery negative cable.
2. Disconnect the electrical connector from
the rear end of the bulb.
