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 conven-
tional type spark plugs since they will last much
longer. Follow the maintenance schedule, 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 log shown in a separate “Service
and Maintenance Guide”. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNING

Operating the engine with the air
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.

Never 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 wind-
shield 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 detergent. Then
rinse the blade with clear water. If your wind-
shield is still not clear after cleaning the bladesand 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.

CAUTION
After wiper blade replacement, return
the wiper arm to its original position;
otherwise it may be damaged when the
hood is opened.
Make sure the wiper blade contacts the
glass, otherwise the arm may be dam-
aged from wind pressure.
Worn windshield wiper blades can dam-
age the windshield and impair driver
vision.
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.
CHECKING PARKING BRAKEPull the parking brake lever up. If the number of
clicks is out of the range as listed above, see
your NISSAN dealer.

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 au-
dible wear indicators. When a brake pad re-
quires 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 indicator sound is heard.
Under some driving or climate conditions, occa-
sional 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 nothave audible wear indicators. Should you ever
hear an unusually loud noise from the rear drum
brakes, have them inspected as soon as pos-
sible by your NISSAN dealer.
Proper brake inspection intervals should
be followed.For additional information, see the
separate “Service and Maintenance Guide”.
BRAKE BOOSTERCheck the brake booster function with the fol-
lowing 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 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 de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
