Appearance Care
Exterior Care
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. See Recommended Fluids
and Lubricants on page 11‑6.
Washing the Vehicle
The best way to preserve the
vehicle's finish is to keep it clean by
washing it often.
Notice: Certain cleaners contain
chemicals that can damage the
emblems or nameplates on the
vehicle. Check the cleaning
product label. If it states that it
should not be used on plastic
parts, do not use it on the vehicle
or damage may occur and it
would not be covered by the
warranty.
