Caution (Continued)
safety precautions, and appropriate
disposal of any vehicle care
product.
Caution
Avoid using high-pressure washes
closer than 30 cm (12 in) to the
surface of the vehicle. Use of power
washers exceeding 8 274 kPa
(1,200 psi) can result in damage or
removal of paint and decals.
Automatic Car Wash
Caution
Automatic car washes can cause
damage to the vehicle, wheels,
ground effects, and convertible top
(if equipped).
Do not use automatic car washes
due to lack of clearance for the
undercarriage, wide rear tires, and
wheels.
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.
VEHICLE CARE
Cleaning Underhood Components
Caution
Do not power wash any component
under the hood that has this
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.
