GMC 2007 Sierra - Manual (Page 592)

Some commercial products may increase gloss on
your instrument panel. The increase in gloss
may cause annoying reflections in the windshield
and even make it difficult to see through the
windshield under certain conditions.
Care of Safety Belts
Keep belts clean and dry.
{ CAUTION:
Do not bleach or dye safety belts. If you
do, it may severely weaken them. In a
crash, they might not be able to provide
adequate protection. Clean safety belts
only with mild soap and lukewarm water.
Weatherstrips
Silicone grease on weatherstrips will make them
last longer, seal better, and not stick or squeak.
Apply silicone grease with a clean cloth. During
very cold, damp weather frequent application may
be required. See Recommended Fluids and
Lubricants on page 629.
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 597. 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.
