remove the plugs. An incorrect wrench
can cause damage.

suitable hexagon wrench. (Front side)
2. Disconnect the electrical connectors.
3. Loosen the ignition coil fixing bolts. And
remove the ignition coil to give access to
the spark plugs.
4. Remove the spark plugs with a spark plug
wrench.
The plug wrench has a rubber seal that
holds the spark plug so that it will not fall
when it is pulled out. Make sure that eachspark plug is snugly fitted into the plug
wrench.
5. Fit the new plugs, one at a time, into the
spark plug wrench and install them. Turn
each plug in several full turns by hand, then
tighten with a spark plug wrench to the
correct torque. Do not overtighten.

6. Holding the ignition coil, re-connect each
ignition coil to its proper spark plug by
pushing it on until you feel a snap.
7. Tighten all ignition coils.
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.
Always replace with recommended
platinum-tipped spark plugs.

The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See ªPeriodic maintenance
schedulesº 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.IOperating the engine with the air
cleaner off can cause you or others to
be burned. The air cleaner not only
cleans the air, it stops flame if theengine 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 or 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 cleaning
the 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 BRAKEFrom the released position, pull the parking
brake lever up slowly and firmly. If the number
of clicks is out of the range listed above, see
your NISSAN dealer.
CHECKING BRAKE PEDALWith the engine running, check the distance
between the upper surface of the pedal and
the metal floor. If it is out of the range shown
above, see your NISSAN dealer.Self-adjusting brakesYour vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
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.
Proper brake inspection intervals should
be followed.For additional information, see
ªPeriodic maintenance schedulesº in the ª9.
Maintenanceº section for maintenance inter-
vals.

BRAKE BOOSTERCheck the brake booster function as follows:
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, see your
NISSAN dealer.Press the pedal by hand and be sure the free
travel is within the limits shown above. If free
travel is too little or too much, see your
NISSAN dealer.
Never use a fuse of higher amperage
rating than that specified on the fuse
box cover. This could damage the elec-
trical system or cause a fire.
