Instrument Panel, Vinyl, and
Other Plastic Surfaces
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is necessary,
a clean soft cloth dampened with a mild soap solution
can be used to gently remove dust and dirt. Never
use spot lifters or removers on plastic surfaces.
Many commercial cleaners and coatings that are
sold to preserve and protect soft plastic surfaces
may permanently change the appearance and feel
of your interior and are not recommended. Do not use
silicone or wax-based products, or those containing
organic solvents to clean your vehicle’s interior because
they can alter the appearance by increasing the gloss
in a non-uniform manner.
Some commercial products may increase gloss on
your instrument panel. The increase in gloss may cause
annoying reflections in the windshield and even make
it difficult to see through the windshield under certain
conditions.
Care of Safety Belts
Keep belts clean and dry.
{
CAUTION:
Do not bleach or dye safety belts. If you do,
it may severely weaken them. In a crash,
they might not be able to provide adequate
protection. Clean safety belts only with mild
soap and lukewarm water.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather frequent application may be required.
