466 Vehicle Care
not use bleach or fabric
softener. Rinse thoroughly and
air dry before next use.
Caution
Do not attach a device with
a suction cup to the display.
This may cause damage and
would not be covered by the
vehicle warranty.
Instrument Panel, Leather,
Vinyl, Other Plastic
Surfaces, Low Gloss Paint
Surfaces, and Natural
Open Pore Wood
Surfaces
Use a soft bristle brush to
remove dust from knobs and
crevices on the instrument
cluster. Use a soft microfiber
cloth dampened with water to
remove dust and loose dirt.
For a more thorough cleaning,
use a soft microfiber cloth
dampened with a mild soap
and water solution.
Caution
Soaking or saturating
leather, especially
perforated leather, as well
as other interior surfaces,
may cause permanent
damage. Wipe excess
moisture from these
surfaces after cleaning and
allow them to dry naturally.
Never use heat, steam,
or spot removers. Do not
use liquids that contain
alcohol or solvents on
leather seats. Do not use
cleaners that contain
silicone or wax-based
products. Cleaners
containing these solvents
can permanently change the
appearance and feel of
leather or soft trim, and are
not recommended.
Do not use cleaners that
increase gloss, especially on
the instrument panel.
Reflected glare can decrease visibility through the
windshield under certain
conditions.
Caution
Use of air fresheners may
cause permanent damage to
plastics and painted
surfaces. If an air freshener
comes in contact with any
plastic or painted surface in
the vehicle, blot immediately
and clean with a soft cloth
dampened with a mild soap
solution. Damage caused by
air fresheners would not be
covered by the vehicle
warranty.
Cargo Cover and
Convenience Net
If equipped, wash with warm
water and mild detergent. Do
not use chlorine bleach. Rinse
with cold water, and then dry
completely.
