Always use waxes and polishes that
are non-abrasive and made for a
basecoat/clearcoat paint finish.
Notice:Machine compounding
or aggressive polishing on a
basecoat/clearcoat paint finish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint finish on the
vehicle.
Foreign materials such as calcium
chloride and other salts, ice melting
agents, road oil and tar, tree sap,
bird droppings, chemicals from
industrial chimneys, etc., can
damage the vehicle's finish if they
remain on painted surfaces. Wash
the vehicle as soon as possible.
If necessary, use non-abrasive
cleaners that are marked safe
for painted surfaces to remove
foreign matter. Exterior painted surfaces are
subject to aging, weather and
chemical fallout that can take their
toll over a period of years. To help
keep the paint finish looking new,
keep the vehicle garaged or
covered whenever possible.
Protecting Exterior Bright
Metal Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Washing with water is all that
is usually needed. However, chrome
polish may be used on chrome or
stainless steel trim, if necessary.
Use special care with aluminum
trim. To avoid damaging protective
trim, never use auto or chrome
polish, steam or caustic soap to
clean aluminum. A coating of
wax, rubbed to high polish, is
recommended for all bright
metal parts.Windshield and Wiper Blades
Clean the outside of the windshield
with glass cleaner.
Clean the rubber blades using a 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.
Wipers can be damaged by:
.Extreme dusty conditions
.Sand and salt
.Heat and sun
.Snow and ice, without proper
removal
