Cleaning leather seats (if equipped)
To clean, simply use a soft cloth dampened with water and a mild soap.
Wipe the leather again with a damp cloth to remove soap residue. Dry
with a soft cloth. For tougher soiling concerns, Ford recommends using
the leather cleaning kit F8AJ-19G253–AA, which is available from your
Ford Dealer. This mild cleaner and special pad, cleans the leather and
maintains its natural beauty. Follow the instructions on the cleaner label.
Regular cleaning of your leather upholstery helps maintain its resiliency
and color.
Do not use household cleaning products, alcohol solutions,
solvents or cleaners intended for rubber, vinyl or plastics.
Woodtone trim
Wipe stains with a soft cloth and a multi-purpose cleaning solution.
Inside windows
Use glass cleaner for the inside windows if they become fogged.
Cleaning mirrors
Do not clean your mirrors with a dry cloth or abrasive materials. Use a
soft cloth and mild detergent and water. Be careful when removing ice
from outside mirrors because you may damage the reflective surface.
