Vehicle Care
Remove any accessories that
may be damaged or interfere
with the car wash equipment.
Hand Wash
Rinse the vehicle well, before
and after washing, 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.
Cleaning Underhood
Components
Caution
Do not power wash any
component under the hood
that has this
e
symbol.
This could cause damage to
the vehicle that would not
be covered by the vehicle
warranty.
Avoid using solvents or
abrasive cleaners that may
harm underhood components.
GM recommends using only
water to clean underhood
components.
If using a pressure washer,
ensure the following criteria
is met:
.
Water pressure must be
kept below 14 000 KPa
(2,000 PSI).
.
Water temperature must be
below 80 °C (180 °F).
.
A spray nozzle with a
40 degree wide angle spray
pattern or wider must be
used, and must be kept at
least 30 cm (1 ft) away from
all surfaces.
Finish Care
Application of aftermarket
clearcoat sealant/wax
materials is not recommended.
If painted surfaces are
damaged, see your dealer to
have the damage assessed
and repaired. Materials such
as calcium chloride and other
salts, ice melting agents, road
oil and tar, tree sap, bird
droppings, chemicals from
industrial chimneys, etc., can
damage the vehicle 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.
Caution
Do not apply waxes or
polishes to uncoated plastic,
vinyl, rubber, decals,
simulated wood, or matte
paint as damage can occur.
