354 Vehicle Care
Caution (Continued)
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.
Caution
Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
finish may damage it. Use only
non-abrasive waxes and 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.
Use only approved cleaning solutions for
aluminum, chrome, or stainless steel.
Some cleaners are highly acidic or contain
alkaline substances and can damage the
moldings.
Always dilute a concentrated cleaner
according to the manufacturer s
instructions.
Do not use cleaners that are not intended
for automotive use.
Use a nonabrasive wax on the vehicle
after washing to protect and extend the
molding finish.
