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 the
interior and are not recommended. Do not use silicone
or wax-based products, or those containing organic
solvents to clean the 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 the
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.
Wood Panels
Use a clean cloth moistened in warm, soapy water
(use mild dish washing soap). Dry the wood
immediately with a clean cloth.
Speaker Covers
Vacuum around a speaker cover gently, so that the
speaker will not be damaged. Clean spots with just
water and mild soap.
Care of Safety Belts
Keep belts clean and dry.
{WARNING:
Do not bleach or dye safety belts. 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.
