Caution
If any accessories are left on or
plugged in during the jump starting
procedure, they could be damaged.
The repairs would not be covered
by the vehicle warranty. Whenever
possible, turn off or unplug all
accessories on either vehicle when
jump starting.
4. Turn the ignition off. Turn off all lights and accessories in both

cause battery gas to explode. People
have been hurt doing this, and
some have been blinded. Use a
flashlight if you need more light.
Battery fluid contains acid that can
burn you. Do not get it on you.
If you accidentally get it in your
eyes or on your skin, flush the place
with water and get medical help
immediately.
{Warning
Fans or other moving engine parts
can injure you badly. Keep your

Caution
To avoid damage to a matte paint
finish, do not use an automatic car
wash equipped with brushes or
scrubbers. Only use touchless
automatic car washes.
If using an automatic car wash, follow
the car wash instructions. The
windshield wiper and rear window
wiper, if equipped, must be off.
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 ComponentsCaution
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).

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.
