When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral). For an automatic trans-
mission, move the shift lever to P
(Park).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts, and any other moving
parts.
cIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.,
before working on your vehicle.cAlways wear eye protection when-
ever you work on your vehicle.
cIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and battery.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) sys-
tem, the fuel filter or fuel lines
should be serviced by an authorized
NISSAN dealer because the fuel
lines are under high pressure even
when the engine is off.
CAUTION
cDo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.cNever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
cAvoid contact with used motor oil.
Improperly disposed motor oil
and/or other vehicle fluids can hurt
the environment. Always conform to
local regulations for disposal of ve-
hicle fluid.
This ``Do-it-yourself'' section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.

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.Pull the parking brake lever up. If the num-
ber of clicks is out of the range listed above,
see an authorized NISSAN dealer.With the engine running, check distance A
between the upper surface of the pedal and
the metal floor.

ZX

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 NIS-
SAN 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 brakeschecked 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 NIS-
SAN dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance Schedule'' section of this
manual.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-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, have
the brakes checked by an authorized NIS-
SAN dealer.
BRAKE BOOSTER

ZX

If you have a flat tire, see the ``In case of
emergency'' section of this manual.
Maximum inflation pressure
Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure
Periodically check the tire pressure (includ-
ing the spare). Tire pressure should be
checked when tires are COLD. COLD tire
pressures are shown on the tire placard
affixed to the inside of the glove box lid.
Incorrect tire pressure may adverselyaffect tire life and vehicle handling.
COLD pressure:
After vehicle has been parked for
three hours or more or driven less
than 1 mile (1.6 km).
WARNING
cImproperly inflated tires can fail sud-
denly and cause an accident
c
The vehicle weight capacity is indi-
cated on the tire placard. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire fail-
ure, or unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
cBefore taking a long trip, or when-
ever you have loaded your vehicle
heavily, use a tire pressure gauge to
ensure that the tire pressure is at the
specified level.
cDo not drive your vehicle over 85
MPH (137 km/h) unless it is equippedwith high capability tires. Driving
faster than 85 MPH (137 km/h) may
result in tire failure, loss of control
and possible injury.
Types of tires
WARNING
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. An authorized NISSAN
dealer may be able to help you with
information about tire type, size, speed
rating and availability. Replacement
tires may have a lower speed rating
than the factory equipped tires, and
may not match the potential maximum
vehicle speed. Never exceed the maxi-
mum speed rating of the tire.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance for
use all year around, including snowy and icy
road conditions. All Season Tires are iden-
tified by ``ALL SEASON'' and/or ``M&S'' on
the tire sidewall. Snow tires have better
DI0047
WHEELS AND TIRES
8-26Do-it-yourself
ZX

snow traction than All Season tires and may
be more appropriate in some areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance in
snow and ice will be substantially reduced.
Summer tires do not have the tire traction
rating ``M&S'' on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of ``SNOW'' or ``ALL SEASON'' tires on
all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
For additional traction on icy roads, studded
tires may be used. However, some U.S.States and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires. Skid
and traction capabilities of studded snow
tires on wet or dry surfaces may be poorer
than that of non-studded snow tires.
Four-wheel drive model
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
CAUTION
ONLY use spare tires specified for each
four-wheel drive model.
Tire chains
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE class ``S'' chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must besecured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or undercarriage. If possible, avoid fully
loading your vehicle when using tire chains.
In addition, drive at a reduced speed. Oth-
erwise, your vehicle may be damaged
and/or vehicle handling and performance
may be adversely affected.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress. When driv-
ing on clear paved roads, be sure to change
to 2WD.

Tire rotation
NISSAN recommends rotating the tires ev-
ery 7,500 miles (12,000 km) for 2WD ve-
hicles and every 3,750 miles (6,000 km) for
4WD vehicles.
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
Wheel nut tightening torque:
87 to 108 ft-lb (118 to 147 Nzm)
WARNING
cAfter rotating the tires, adjust the tire
pressure.
cRetighten the wheel nuts after the
wheels have been run for the first
600 miles (1,000 km) (also in cases of
a flat tire, etc.).
cDo not include the TEMPORARY
USE ONLY spare tire in the tire rota-
tion.
Tire wear and damage
WARNING
cTires should be periodically in-
spected for wear, cracking, bulging
or objects caught in the tread. If
excessive wear, cracks, bulging or
deep cuts are found, the tire should
be replaced.
cThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire should be
replaced.

cImproper service for a TEMPORARY
USE ONLY spare tire may result in
serious personal injury. If it is nec-
essary to repair the TEMPORARY
USE ONLY spare tire, contact an
authorized NISSAN dealer.
Changing tires and wheels
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. Recom-
mended types and sizes are shown in
``Wheel/tire size'' in the ``Technical and con-
sumer information'' section of this manual.
WARNING
c
The use of tires other than those
recommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, snow 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 offset dimen-
sion. Wheels of a different offset
could cause early tire wear, poor ve-
hicle handling characteristics and/or
interference with the brake discs/
drums. Such interference can lead to
decreased braking efficiency and/or
early brake pad/shoe wear.
cDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
cThe use of retread tires is not recom-
mended.
FOUR-WHEEL DRIVE
MODELS
CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tireson the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer
case and differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. Contact an
authorized NISSAN dealer.
CAUTION
ONLY use spare tires specified for each
four-wheel drive model.
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 performed
with the wheels off the vehicle. Spin balanc-
ing the front wheels on the vehicle could
lead to transmission damage.
