Unfastening the seat belt
To unfasten the belt, press the button on the
buckle.
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.
cPersons who can use the standard
seat belt should not use an extender.
Such unnecessary use could result
in serious personal injury in the
event of an accident.
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 the 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 re-
placed.ARS1058

(manual transmission vehicles), us-
ing only the brake, as this could
cause loss of control.
cHeavy braking going down a hill
could cause your brakes to overheat
and fade, resulting in loss of control
and an accident. Apply brakes lightly
and use a low gear to control your
speed.
cUnsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure all cargo so it
will not be thrown forward and cause
injury to you or your passengers.
cTo avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so
equipped) and evenly distribute the
load. Secure heavy loads in the
cargo area as far forward and as low
as possible. Do not equip the vehicle
with tires larger than specified in this
manual. This could cause your ve-
hicle to roll over.
cDo not grip the inside or spokes of
the steering wheel when driving off-
road. The steering wheel could movesuddenly and injure your hands. In-
stead drive with your fingers and
thumbs on the outside of the rim.
cBefore operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
cAlways drive with the floor mats in
place as the floor may become hot.
cLower your speed when encounter-
ing strong crosswinds. With a higher
center of gravity, your NISSAN is
more affected by strong side winds.
Slower speeds ensure better vehicle
control.
cDo not drive beyond the perfor-
mance of the tires, even with 4WD
engaged.
cAccelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
cIf at all possible, avoid sharp turning
maneuvers, particularly at high
speeds. Your NISSAN four-wheel
drive vehicle has a higher center of
gravity than a two-wheel drive veh-icle. The vehicle is not designed for
cornering at the same speeds as
conventional two-wheel drive ve-
hicles. Failure to operate this vehicle
correctly could result in loss of con-
trol and/or a roll over accident.
cAlways use tires of the same type,
size, brand, construction (bias, bias-
belted, or radial), and tread pattern
on all four wheels. Install tire chains
on the rear wheels when driving on
slippery roads and drive carefully.
cBe sure to check the brakes immedi-
ately after driving in mud or water.
See(Brake system(later in this sec-
tion for(Wet brakes(.
cAvoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
cWhenever you drive off-road
through sand, mud or water as deep
as the wheel hub, more frequent-
maintenance may be required. See
(Periodic maintenance(in the(Main-
tenance(section of this manual.

If an abnormality occurs in the system, the
anti-lock function will cease but the ordinary
brakes will continue to operate normally. The
ABS brake warning light will then come on.
If the light comes on while you are driv-
ing, contact an authorized NISSAN
dealer for repair.
WARNING
cThe anti-lock brake system is a so-
phisticated device, but it cannot pre-
vent accidents resulting from care-
less or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces, but remember that the
stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with the anti-lock
brake system. Stopping distances
may also be longer on rough, gravel,
or snow covered roads, or if you are
using tire chains. Always maintain a
safe distance from the vehicle in
front of you. Ultimately, the respon-
sibility for safety of self and others
rests in the hands of the driver.Tire type and condition may also
affect braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all four
wheels.
cWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
``Tire placard'' in the ``Technical and
consumer information'' section of
this manual.
For additional information, refer to9Wheels
and Tires9in the9Do-it-yourself9section of
this manual.
FREEING A FROZEN DOOR
LOCK
To prevent a door lock from freezing, apply
de-icer or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore inserting it in the key hole.
ANTI-FREEZE
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check anti-freeze (ethylene glycol base) to
assure proper winter protection. For details,
see ``Engine cooling system'' in the ``Do-it-
yourself'' section of this manual.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Do-it-yourself''
section of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the

radiator and on the engine block. Refill
before operating the vehicle. For details,
see ``Changing engine coolant'' in the ``Do-
it-yourself'' section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use on all four
wheels of MUD & SNOW or ALL SEA-
SON tires. Please consult your NISSAN
dealer for the tire type, size, speed rating
and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit 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.
3. Tire chains may be used. Use of tirechains may be prohibited according to
location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are
installed according to the chain manufac-
turer's suggestions.Use only SAE
Class ``S'' chains.Other types may
damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose
end links of the tire chain must be se-
cured or removed to prevent the possi-
bility 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, otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely af-
fected. Never install tire chains on a
TEMPORARY USE ONLY spare tire. Do
not use tire chains on dry roads.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
1. A scraper and stiff-bristled brush to re-move ice and snow from the windows
and wiper blades.
2. A sturdy, flat board to be placed under
the jack to give it firm support.
3. A shovel to dig the vehicle out of snow-
drifts.
4. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
cWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow, or ice can be slick
and very hard to drive on. The ve-
hicle will have much less traction or
``grip'' under these conditions. Try to
avoid driving on wet ice until the
road is salted or sanded.
cWhatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction.
c
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.

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-
DI0047
WHEELS AND TIRES

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.

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
