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.
IPark 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
Neutral. For an automatic transmis-
sion, move the selector lever to ªPº
(Park).
IBe sure the ignition key is in the
ªOFFº or ªLOCKº position when per-
forming any replacement or repair.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving fans
and fan belts.
IIt is advisable to remove necktie and
any jewelry, such as rings, watches,
etc. before working on your vehicle.IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
INever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and battery.
IThe fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
IDo not work under the engine hood
while it is hot. Always turn off the
engine and wait until it cools down.
INever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
IAvoid direct contact with used engineoil. Improperly disposed motor oil and/
or other vehicle fluids can hurt the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This ªDo-it-yourself operationsº section gives
instructions regarding only those items which
are relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage.If in doubt about
any servicing, have it done by your NISSAN
dealer.
PRECAUTIONS
7-2
Z01.2.1/R50-DX

If you have a flat tire, see ªIn case of
emergencyº section.
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 (including
spare). Incorrect tire pressure may adversely
affect tire life and vehicle handling. Tire pres-
sure should be checked when tires are COLD.
Tires are considered COLD after the vehicle
has been parked for three or more hours, or
driven less than 1 mile (1.6 km). COLD tirepressures are shown on the tire placard affixed
to the inside of the glove box lid.
IThe vehicle capacity weight 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.
IBefore taking a long trip, or whenever
you have loaded your vehicle heavily,
use a tire pressure gauge to ensure
that the tire pressure is at the speci-
fied level.
IDo not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed capability tires. Driv-
ing faster than 85 MPH (140 km/h)
may result in tire failure, loss of con-trol and possible injury.
Types of tires
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. Your 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 maximum 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 identified by
ªALL SEASONº and/or ªM&Sº on the tire side-
wall. Snow tires have better snow traction than
All Season tires and may be more appropriate
in some areas.

Z01.2.1/R50-DX

Summer tires
NISSAN specifies summer tires on some mod-
els 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 ªM&Sº on
the tire sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, NISSAN recommends the use
of ªSNOWº or ªALL SEASONº 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 handling 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 provinces
and states 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 bepoorer than that of non-studded snow tires.
4-wheel drive model
If you install snow tires, they must also be the
same size, brand, construction and tread pat-
tern on all four wheels.
ONLY use spare tires specified for each
4-wheel drive model.
Tire chains
Use of tire chains is 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 manufacturer's suggestions.Use only
SAE class ªSº chains.Other types may
damage your vehicle. Use chain tensioners
when recommended by the tire chain manu-
facturer to ensure a tight fit. Loose end links of
the tire chain must be secured or removed to
prevent the possibility of whipping action dam-
age to the fenders or underbody. If possible,
avoid fully loading your vehicle when using tire
chains. In addition, drive at a reduced speed.
Otherwise, your vehicle may be damagedand/or vehicle handling and performance may
be adversely affected.
Do not use tire chains on dry roads.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains in
such conditions can cause damage to the
various mechanisms of the vehicle due to
some overstress. When driving on clear paved
roads, be sure to change to 2WD.

Tire rotation
NISSAN recommends that tires be rotated
every 7,500 miles (12,000 km) for 2WD ve-
hicles and 3,750 miles (6,000 km) for 4WD
vehicles.
See ªFlat tireº in the ªIn case of emergencyº
section for tire replacing procedures.
Wheel nut tightening torque:
87 to 108 ft-lb (118 to 147 N×m)
IAfter rotating the tires, adjust the tire
pressure.
IRetighten the wheel nuts after the
aluminum wheel has been run for the
first 600 miles (1,000 km). (also in
cases of a flat tire, etc.)
Tire wear and damage
ITires should be periodically in-
spected for wear, cracking, bulging
or objects caught in the tread. If ex-
cessive wear, cracks, bulging or deep
cuts are found, the tire should be
replaced.
IThe original tires have a built-in tread
wear indicator. When the wear indica-
tor is visible, the tire should be
DI0048-BMDI0004

replaced.
Changing tires and wheels
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. Recommended types and
sizes are shown in ªWheels and tiresº in the
ªTechnical informationº section.
IThe 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.
IIf 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, possiblydegraded vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear.
IDo 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
warning.
4-WHEEL DRIVE MODELS
Always use tires of the same size, brand,
construction (bias, bias-belted or ra-
dial), 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 dam-
age the transmission, transfer case and
differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with tiresof the same size, brand, construction and
tread pattern. The tire pressure and wheel
alignment should also be checked and cor-
rected as necessary. Contact your NISSAN
dealer.
ONLY use spare tires specified for each
4-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 balancing
the rear wheels on the vehicle could lead to
transmission damage.

Z01.2.1/R50-DX

Care of wheels
IWash the wheels when washing the vehicle
to maintain their appearance.
IClean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
IDo not use abrasive cleaners when wash-
ing the wheels.
IInspect wheel rims regularly for dents or
corrosion. This may cause loss of pressure
or damage the tire bead.
IWe recommend that the road wheels be
waxed to protect against road salt in areas
where it is used during winter.
Checking water entry
Whenever you drive in deep water or mud,
check water entry in the clutch housing by
removing the blind plug at the bottom of the
transmission case. After checking, be sure to
reinstall the plug.

Your new NISSAN has been designed to have
minimum maintenance requirements with
longer service intervals to save you both time
and money. However, some day- to-day and
regular maintenance is essential to maintain
your NISSAN's good mechanical condition, as
well as its emission and engine performance.
It is the owner's responsibility to make sure
that the specified maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives the
proper maintenance care. You are a vital link
in the maintenance chain.
General maintenance
General maintenance includes those items
which should be checked during normal day-
to-day operation of the vehicle. They are es-
sential if your vehicle is to continue to operate
properly. It is your responsibility to perform
these procedures regularly as prescribed.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer,
your NISSAN dealer.
Periodic maintenance
The maintenance items listed in this part are
required to be serviced at regular intervals.However, under severe driving conditions, ad-
ditional or more frequent maintenance will be
required.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the sys-
tems checked and tuned by an authorized
NISSAN dealer.
NISSAN technicians are well-trained special-
ists and are kept up to date with the latest
service information through technical bulletins,
service tips, and in-dealership training pro-
grams. They are completely qualified to work
on NISSAN's vehicles before they work on
your vehicle, rather than after they have
worked on it.
You can be confident that your NISSAN deal-
er's service department performs the best job
to meet the maintenance requirements on your
vehicle Ð in a reliable and economic way.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have
your NISSAN dealer do it promptly. In addition,
you should notify your NISSAN dealer if you
think that repairs are required.
When performing any checks or maintenance
work, closely observe the precautions in the
ªDo-it-yourself operationsº section.
Additional information on the following
items with ª*º is found in the ªDo-it-
yourself operationsº section.
OUTSIDE THE VEHICLE
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
