CAUTION
c
After wiper blade replacement, return
the wiper arm to its original position;
otherwise it may be damaged when
the engine hood is opened.
cMake sure the wiper blades contact
the glass; otherwise the arms may
be damaged from wind pressure.
cWorn windshield wiper blades can
damage the windshield and impair
driver vision.
CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade chat-
ters when running, wax or another 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 aftercleaning the blades and using the wiper,
replace the blades.REPLACING
Replace the wiper blades if they are worn.
1. Lift the wiper arm away from the wind-
shield.
2. Push the release tab, then move the
wiper blade down the wiper arm to re-
move.
3. Remove the wiper blade.
4. Insert the new wiper blade onto the wiper
arm until it clicks into place.

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 BRAKE
From the released position, firmly push the
parking brake down. If the number of clicks
is out of the range listed above, see an
authorized NISSAN dealer.
CHECKING BRAKE PEDAL
With the engine running, check distance A
between the upper surface of the pedal and
the metal floor.

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
NISSAN 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 brakes
checked 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
NISSAN dealer.Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``NISSAN Service and Maintenance Guide.''
BRAKE BOOSTER
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-

cAiming is not necessary after replac-
ing the bulb. When aiming adjust-
ment is necessary, contact an autho-
rized NISSAN dealer.
cDo not leave the bulb out of the
headlight reflector for a long period
of time as dust, moisture, and smoke
may enter the headlight body and
affect the performance of the head-
light.
Replacing the headlight bulb
1. Open the hood.
2. Disconnect the negative (2) battery
cable.
3 Disconnect the electrical connector from
the rear end of the bulb.
4. Turn the bulb retaining ring counterclock-
wise until it is free from the headlamp

5. Carefully remove the headlight bulb. Do
not shake or rotate the bulb when remov-
ing it.
DO NOT TOUCH THE BULB.6. Install the new bulb in the reverse order
of removal.
cBe sure the lip of the bulb socket
contacts the headlight body.
Adjusting the headlight aim
Before performing aiming adjustment, make
sure of the following:
a. Use an aiming wall screen.
b. Keep all of the tires inflated to the correct
pressure.
c. Place the vehicle and screen on level
ground.
d. See that the vehicle is unloaded (except
for full levels of coolant, engine oil and
fuel, and that the spare tire, jack, and
tools are stored). Have the driver or an
equivalent weight placed in the driver's
seat.
1. Open the hood. Turn headlight low beam
on.
2. Adjust the vertical aim by turning the
adjustment screw.cCover the opposite headlight and ensure
the fog lights (if so equipped) are turned
off.
cAdjust beam pattern until cutoff line is
positioned at the same height off ground
as bulb center (on H-line).
