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 manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the selector
lever to P (Park).
cBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
cNever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
cNever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.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 secure or remove
any loose clothing and remove 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 to escape.
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 tank and bat-
tery.
cOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by an authorized NISSANdealer because the fuellines are un-
der 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 engine oil
and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal 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.

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 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 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.
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-

If you have a flat tire, see the ``In case of
emergency'' section of this manual.
TIRE PRESSURE
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 adversely
affect 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 F.M.V.S.S. certification
label. Do not load your vehicle be-
yond this capacity. Overloading your
vehicle may result in reduced tire life,
unsafe operating conditions due to
premature tire failure, or unfavorable
handling characteristics and could
also lead to a serious accident. Load-
ing beyond the specified capacity
may also result in failure of other
vehicle components.
cBefore taking a long trip, or when-
ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressure is at the speci-
fied level.cDo not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed rated tires. Driving
faster than 85 MPH (140 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
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.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
Generally, snow tires will have lower speed
ratings than factory equipped tires and maynot 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.
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 be
secured 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.

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires ev-
ery 7,500 miles (12,000 km).
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, check and
adjust the tire pressure.
cRetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
cDo not include the spare tire in the
tire rotation.
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(s)
should be replaced.
cThe original tires have a built-in
tread wear indicator. When the wear
indicators are visible, the tire(s)
should be replaced.

cImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an authorized
NISSAN dealer.
Replacing 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, 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 offset dimen-
sion. Wheels of a different offset
could cause pre-mature tire wear, de-
grade vehicle handling characteris-
tics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. Refer to(Wheel/tire size(in the
(Technical and consumer informa-
tion(section of this manual for wheel
off-set dimensions.
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.
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 tires
on 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.
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.

Care of wheels
cWash the wheels when washing the ve-
hicle 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.
cInspect wheel rims regularly for dents or
corrosion. This may cause loss of pres-
sure or damage 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)
Your vehicle may be equipped with a TEM-
PORARY USE ONLY spare tire.
To avoid property damage or personal injury
when using the TEMPORARY USE ONLY
spare tire, observe the following cautions:
WARNING
cThe spare tire should be used for
emergency use only. It should be
replaced with the standard tire at the
first opportunity to avoid possible
tire or differential damage.
cDrive carefully while the TEMPO-
RARY USE ONLY spare tire is in-
stalled. Avoid sharp turns and
abrupt braking while driving.
cPeriodically check spare tire infla-
tion pressure. Always keep the pres-
sure of the TEMPORARY USE ONLY
spare tire at 60 psi (420 kPa, 4.2 bar).
Always keep the pressure of the full
size spare tire (if so equipped) at the
recommended pressure for standard
tires, as indicated on the tire placard.
For tire placard location, see(Tire
placard(in the index of this manual .
cWith the TEMPORARY USE ONLY
spare tire installed do not drive the
vehicle at speeds faster than 50 MPH
(80 km/h).
c
When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used onthe front wheels and the original tire
used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
cTire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster
rate than the standard tire. Replace
the spare tire as soon as the tread
wear indicators appear.
cDo not use the spare tire on other
vehicles.
cDo not use more than one spare tire
at the same time.
cDo not tow a trailer when the TEM-
PORARY USE ONLY spare tire is
installed.
CAUTION
c
With the spare tire installed the
transfer control lever must be in the
2H position to prevent the transfer
case and differential gears from be-
ing damaged.
cDo not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire
