Do not use silicone or wax-based
products, or those containing
organic solvents to clean the
interior because they can alter
the appearance by increasing the
gloss in a non-uniform manner.
To remove dust, a soft cloth
dampened with water can be
used. 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 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.
Keep belts clean and dry.
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.
