ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off the ground.

vehicle with all four wheels on the
ground, or even with only two of
its wheels on the ground, will
damage drivetrain components.

vehicle with any of its wheels on
the ground.Appearance Care

or plastic parts. If damage
occurs, it would not be covered

Vehicle Care 10-95
Windshield and Wiper Blades
Clean the outside of the windshield
with glass cleaner.
Clean rubber blades using lint-free
cloth or paper towel soaked with
windshield washer fluid or a mild
detergent. Wash the windshield
thoroughly when cleaning the
blades. Bugs, road grime, sap, and
a buildup of vehicle wash/wax
treatments may cause wiper
streaking.
Replace the wiper blades if they
are worn or damaged. Damage can
be caused by extreme dusty
conditions, sand, salt, heat, sun,
snow and ice.
Weatherstrips
Apply silicone grease on
weatherstrips to make them last
longer, seal better, and not stick or
squeak. SeeRecommended Fluids
and Lubricants on page 11‑12.
Tires
Use a stiff brush with tire cleaner to
clean the tires.
Notice: Using petroleum-based
tire dressing products on the
vehicle may damage the paint
finish and/or tires. When applying
a tire dressing, always wipe off
any overspray from all painted
surfaces on the vehicle.
Wheels and Trim —Aluminum
or Chrome
Use a soft, clean cloth with mild
soap and water to clean the wheels.
After rinsing thoroughly with clean
water, dry with a soft, clean towel.
A wax may then be applied.
Keep the wheels clean using a
soft, clean cloth with mild soap and
water. Rinse with clean water. After
rinsing thoroughly, dry with a soft,
clean towel. A wax may then be
applied. Notice:
Chrome wheels and other
chrome trim may be damaged if
the vehicle is not washed after
driving on roads that have been
sprayed with magnesium,
calcium, or sodium chloride.
These chlorides are used on
roads for conditions such as
ice and dust. Always wash the
chrome with soap and water after
exposure.
Notice: To avoid surface damage,
do not use strong soaps,
chemicals, abrasive polishes,
cleaners, brushes, or cleaners
that contain acid on aluminum or
chrome-plated wheels. Use only
approved cleaners. Also, never
drive a vehicle with aluminum or
chrome-plated wheels through an
automatic car wash that uses
silicone carbide tire cleaning
brushes. Damage could occur
and the repairs would not be
covered by the vehicle warranty.
