300 VEHICLE CARE
Protecting Exterior Bright Metal
Mouldings
Caution
Failure to clean and protect the
bright metal mouldings can result
in a hazy white finish or pitting.
This damage would not be covered
by the vehicle warranty.
The bright metal mouldings on the
vehicle are aluminium, chrome,
or stainless steel. To prevent damage,
always follow these cleaning
instructions:
Be sure the moulding is cool to
the touch before applying any
cleaning solution.
Use only approved cleaning
solutions for aluminium, chrome,
or stainless steel. Some cleaners
are highly acidic or contain
alkaline substances and can
damage the mouldings.
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 moulding 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 bonnet and windscreen
when washing the vehicle.
