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

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.
Do not wash the vehicle in direct
sunlight. Use a car washing soap.
Do not use cleaning agents that are
petroleum based or that contain
acid or abrasives, as they can
damage the paint, metal or plastic
on the vehicle. Approved cleaning
products can be obtained from your
dealer. Follow all manufacturers'
directions regarding correct product
usage, necessary safety
precautions and appropriate
disposal of any vehicle care
product.
Rinse the vehicle well, before
washing and after to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.
