Maintenance
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.Tire traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. Slow down whenever there
is rain, snow or ice on the road, to
reduce the possibility of losing con-
trol of the vehicle.Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,
speedometer and odometer cal-
ibration, headlight aim and
bumper height.

Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
APPEARANCE CARE
CAUTION
• Do not use strong soap, chemical
detergents or hot water, and do
not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
• Be careful when washing the side
windows of your vehicle.
Especially, with high-pressure
water, water may leak through the
windows and wet the interior.
• To prevent damage to the plastic
parts and lamps, do not clean
with chemical solvents or strong
detergents.
WARNING - Wet brakes
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.
CAUTION
• Water washing in the engine com-
partment including high pressure
water washing may cause the fail-
ure of electrical circuits or engine
and related part located in the
engine compartment.
• Never allow water or other liquids
to come in contact with electri-
cal/electronic components and
air duct inside the vehicle as this
may damage them.

Maintenance
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may col-
lect on the underbody. If these materials
are not removed, accelerated rusting can
occur on the underbody parts such as
the fuel lines, frame, floor pan and
exhaust system, even though they have
been treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Pay
special attention to these areas because
it is difficult to see all the mud and dirt. It
will do more harm than good to wet down
the road grime without removing it. The
lower edges of the doors, rocker panels,
and frame members have drain holes
that should not clog with dirt; trapped
water in these areas can cause rusting.
Aluminum or chrome wheel mainte-
nance
The aluminum or chrome wheels are
coated with a clear protective finish.
• Do not use any abrasive cleaner, pol-
ishing compound, solvent, or wire
brushes on aluminum or chrome
wheels. They may scratch or damage
the finish.
• Clean the wheel when it has cooled.
• Use only a mild soap or neutral deter-
gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
• Avoid washing the wheels with high-
speed car wash brushes.
• Do not use any alkaline or acid deter-
gent. It may damage and corrode the
aluminum or chrome wheels coated
with a clear protective finish.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.
