322 Vehicle Care
Be sure the molding is cool to
the touch before applying any
cleaning solution.
Use only approved cleaning
solutions for aluminum, chrome,
or stainless steel. Some
cleaners are highly acidic or
contain alkaline substances and
can damage the moldings.
Always dilute a concentrated
cleaner according to the
manufacturer s instructions.
Do not use cleaners that are not
intended for automotive use.
Use a nonabrasive wax on the
vehicle after washing to protect
and extend the molding finish.
Cleaning Exterior Lamps/
Lenses, Emblems, Decals, and
Stripes
Use only lukewarm or cold water, a
soft cloth, and a car washing soap
to clean exterior lamps, lenses,
emblems, decals, and stripes.
Follow instructions under "Washing
the Vehicle" previously in this
section.
Lamp covers are made of plastic,
and some have a UV protective
coating. Do not clean or wipe them
when dry.
Do not use any of the following on
lamp covers:
Abrasive or caustic agents.
Washer fluids and other cleaning
agents in higher concentrations
than suggested by the
manufacturer.
Solvents, alcohols, fuels,
or other harsh cleaners.
Ice scrapers or other hard items.
Aftermarket appearance caps or
covers while the lamps are
illuminated, due to excessive
heat generated.
Caution
Failure to clean lamps properly
can cause damage to the lamp
cover that would not be covered
by the vehicle warranty.
Caution
Using wax on low gloss black
finish stripes can increase the
gloss level and create a
non-uniform finish. Clean low
gloss stripes with soap and
water only.
Air Intakes
Clear debris from the air intakes,
between the hood and windshield,
when washing the vehicle.
