Checking seat belt operation
Your seat belt retractors are designed to lock
seat belt movement by two separate meth-
ods:
1) When the seat belt is pulled quickly from
the retractor.
2) When the vehicle slows down rapidly.
To increase your confidence in the seat
belts, check the operation as follows.
cGrasp the shoulder belt and pull forward
quickly. The retractor should lock and
restrict further belt movement.
If the retractor does not lock during this check
or if you have any question about belt opera-
tion, see an authorized NISSAN dealer.Center of rear seat
Selecting correct set of seat belts:
The center seat belt buckle is identified by
the word ``CENTER.'' The center seat belt
tongue can be fastenedonlyinto the center
seat belt buckle.
Shoulder belt height adjustment
(For front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. (See
``Precautions on seat belt usage'' earlier in
this section.) To adjust, pull out the adjust-
ment button and move the shoulder belt
anchor to the desired position, so the belt
passes over the center of the shoulder. The
belt should be away from your face and
neck, but not falling off your shoulder. Re-
lease the adjustment button to lock the
shoulder belt anchor into position.

WARNING
cAfter adjustment, release the adjust-
ment button and try to move the
shoulder belt anchor up and down to
make sure it is securely fixed in
position.
cThe shoulder belt anchor height
should be adjusted to the position
best for you. Failure to do so may
reduce the effectiveness of the en-
tire restraint system and increase
the chance or severity of injury in an
accident.
SEAT BELT EXTENDERS
If, because of body size or driving position,
it is not possible to properly fit the lap-
shoulder belt and fasten it, an extender is
available which is compatible with the in-
stalled seat belts. The extender adds ap-
proximately 8 inches (200 mm) of length
and may be used for either the driver or front
passenger seating position. See an autho-
rized NISSAN dealer for assistance if the
extender is required.
WARNING
cOnly NISSAN seat belt extenders,
made by the same company which
made the original equipment seat
belts, should be used with NISSAN
seat belts.
cAdults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use
could result in serious personal in-
jury in the event of an accident.
Never use seat belt extenders to in-
stall child restraints. If the child re-
straint is not serviced properly, the
child could be seriously injured in a
collision or sudden stop.SEAT BELT MAINTENANCE
cTo clean the seat belt webbings,apply
a mild soap solution or any solution
recommended for cleaning upholstery or
carpet. Then wipe with a cloth and allow
the seat belts to dry in the shade. Do not
allow the seat belts to retract until they
are completely dry.
cIf dirt builds up in the shoulder belt
guideof the seat belt anchors, the seat
belts may retract slowly. Wipe the shoul-
der belt guide with a clean, dry cloth.
c
Periodically check to see that the seat
belt and metal components,such as
buckles, tongues, retractors, flexible
wires and anchors, work properly. If loose
parts, deterioration, cuts or other damage
on the webbing is found, the entire seat
belt assembly should be replaced.

CHECKING BRAKE PEDAL
With 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 an authorized NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front (and rear, if equipped) disc-type
brakes self-adjust every time the brake
pedal is applied. The rear drum-type brakes
also 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 adjust-
ment of the rear drum brakes. To adjust,
apply the parking brake several times.
WARNING
See an authorized NISSAN dealer for a
brake system check if the brake pedal
height does not return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have
an audible wear indicator. When a brake
pad requires replacement, it makes 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. Shouldyou 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 as fol-
lows:
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.

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 anequivalent 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 light 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).

braking, handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.
cIf the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different offset
could cause premature tire wear, de-
grade vehicle handling characteris-
tics and/or interference with the
brake discs/drums. Such interfer-
ence can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. Refer to ªWheel/tire
sizeº in the ªTechnical and con-
sumer informationº section of this
manual for wheel off-set dimen-
sions.
cDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have unknown
structural damage and could fail
without warning.cThe use of retread tires is not recom-
mended.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle. Spin
balancing the front wheels on the vehicle
could lead to transmission damage.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Informa-
tion Booklet (US) or ``Tire Safety In-
formation'' in the Warranty and Road-
side Assistance Information booklet
(Canada).
Care of wheels
cWash the wheels when washing the
vehicle to maintain their appearance.
cClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
cDo not use abrasive cleaners when
washing the wheels.
c
Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
cNISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.
Spare tire (TEMPORARY USE
ONLY)
Observe the following precautions if the TEM-
PORARY USE ONLY spare tire must be used,
otherwise your vehicle could be damaged or
involved in an accident:
