3. Check each new spark plug gap with a
feeler gauge. Correct it as required.
4. Install spark plugs.
When installing a plug, turn it in two or
three turns by hand and then tighten with a
spark plug wrench. Be careful not to over-
tighten it.
Tightening torque:
14 to 22 ft-lb (20 to 29 N×m)
5. Reconnect the spark plug cables to their
original positions.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 in the ª9. Maintenanceº section for
maintenance intervals. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.

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 it off, and
be careful working on the engine with
the air cleaner off.
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.
REPLACEMENT1. 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.

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.
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.

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 disc-type brakes self-adjust every
time the brake pedal is applied. The rear
drum-type brakes self-adjust every time the
parking brake 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.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 in the ª9. Mainte-
nanceº section for maintenance intervals.
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.

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, see ªMaintenance precautionsº in the ª8.
Do-it-yourselfº section.
EXTERIOR MAINTENANCEAdditional information on the following
items with * is found in the ª8. Do-it-
yourselfº section.Outside the vehicleThe maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Tires*:
Check the pressure with a gauge periodically
when at a service station, including the spare,
and adjust to the specified pressure if neces-
sary. Check carefully for damage, cuts or
excessive wear.
