Cleaning the Interior Lamps
Your interior dome lamps and map lamps are plastic and
should be cleaned with a mild detergent diluted in water. Rinse
them with clear water.
Cleaning the Seats
Leather and vinyl
For routine cleaning, wipe the surface with a soft, damp cloth.
For more thorough cleaning, wipe the surface with a leather
cleaner of a mild soap.
Fabric
Remove dust and loose dirt with a whisk broom or a vacuum
cleaner. Remove fresh spots immediately. Follow the directions
that come with the cleaner.
NOTE: Before using any cleaner, test it on a small, hidden
area of fabric. If the fabric's color or texture is
adversely affected by a particular cleaner, do not use
it.
