Washing Your Vehicle
The paint finish on the vehicle provides beauty, depth of
color, gloss retention, and durability.
The best way to preserve the vehicle’s finish is to keep it
clean by washing it often with lukewarm or cold water.
Do not wash the vehicle in the direct rays of the sun.
Use a car washing soap. Do not use strong soaps
or chemical detergents. Be sure to rinse the vehicle well,
removing all soap residue completely. GM-approved
cleaning products can be obtained from your dealer. See
Vehicle Care/Appearance Materials on page 5-95. Do
not use cleaning agents that are petroleum based,
or that contain acid or abrasives. All cleaning agents
should be flushed promptly and not allowed to dry on the
surface, or they could stain. Dry the finish with a soft,
clean chamois or an all-cotton towel to avoid surface
scratches and water spotting.
Notice: If you drive your vehicle through an
automatic car wash that does not have enough
clearance for the wide rear tires and wheels, you
could damage your vehicle. Verify with the manager
of the car wash that your vehicle will fit before
entering the car wash or use a touchless car wash.
High pressure car washes may cause water to enter
the vehicle.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses. Follow
instructions under Washing Your Vehicle on page 5-91.
