Recommend water only.
A pressure washer may be
used, but care must be utilized.
The following criteria must be
followed:
.Water pressure must be
kept below 14 000 KPa
(2,000 PSI).
.Water temperature must be
below 80 °C (180 °F).
.Spray nozzle with a
40 degree wide angle spray
pattern or wider must
be used.
.Nozzle must be kept at least
30 cm (1 ft) away from all

Finish Care
Application of aftermarket
clearcoat sealant/wax is not
recommended. If painted
surfaces are damaged, see
your dealer to have the
damage assessed and
repaired. Foreign materials
such as calcium chloride and
other salts, ice melting agents,
road oil and tar, tree sap, birddroppings, chemicals from
industrial chimneys, etc., can
damage the vehicle's finish if
they remain on painted
surfaces. Wash the vehicle as
soon as possible. If necessary,
use non-abrasive cleaners that
are marked safe for painted
surfaces to remove foreign
matter.
Occasional hand waxing or
mild polishing should be done
to remove residue from the
paint finish. See your dealer
for approved cleaning
products.
Do not apply waxes or
polishes to uncoated plastic,
vinyl, rubber, decals, simulated
wood, or flat paint as damage
can occur.
Caution
Machine compounding or
aggressive polishing on a
basecoat/clearcoat paint
finish may damage it. Use
only non-abrasive waxes and
(Continued)
Caution (Continued)
polishes that are made for a
basecoat/clearcoat paint
finish on the vehicle.
To keep the paint finish
looking new, keep the vehicle
garaged or covered whenever
possible.
Protecting Exterior Bright
Metal Moldings
Caution
Failure to clean and protect
the bright metal moldings
can result in a hazy white
finish or pitting. This damage
would not be covered by the
vehicle warranty.
The bright metal moldings on
the vehicle are aluminum,
chrome, or stainless steel. To
prevent damage always follow
these cleaning instructions:
.Be sure the molding is cool
to the touch before applying
any cleaning solution.

Vehicle Care 417
Original manufacturer
replacement parts will provide
the corrosion protection while
maintaining the vehicle
warranty.
Finish Damage
Quickly repair minor chips and
scratches with touch-up
materials available from your
dealer to avoid corrosion.
Larger areas of finish damage
can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall
upon and attack painted
vehicle surfaces causing
blotchy, ring-shaped
discolorations, and small,
irregular dark spots etched
into the paint surface. See
“Finish Care”previously in this
section.
Interior Care
To prevent dirt particle
abrasions, regularly clean the
vehicle's interior. Before using cleaners, read and follow all
safety instructions on the
label. While cleaning the
interior, open the doors and
windows to get proper
ventilation. Newspapers or
dark garments can transfer
color to the vehicle’s interior.
Caution
Immediately remove
cleaners, hand lotions,
sunscreen, and insect
repellent from all interior
surfaces or permanent
damage may result.
Caution
Use cleaners specifically
designed for the surfaces
being cleaned to prevent
permanent damage to the
vehicle. Apply all cleaners
directly to a cleaning cloth.
Do not spray cleaners on
any switches or controls.
When using liquid soap
cleaners, follow the directions
on the specific cleaner or soap
solution for dilution
instructions.
Caution
To prevent damage:
.Never use a razor or any
other sharp object to
remove soil from any
interior surface
.Never use a brush with
stiff bristles.
.Never rub any surface
aggressively or with too
much pressure.
.Do not get any exposed
electrical components wet.
.Do not use laundry
detergents or dishwashing
soaps with degreasers. Do
not use solutions that
contain strong or
caustic soap.
