Windshield And Wiper Blades; Aluminum Or Chrome-Plated Wheels - GMC TopKick 2007 Owner's Manual

Windshield and Wiper Blades

If the windshield is not clear after using the
windshield washer, or if the wiper blade chatters
when running, wax, sap, or other material may
be on the blade or windshield.
Clean the outside of the windshield with a glass
cleaning liquid or powder and water solution.
The windshield is clean if beads do not form when
it is rinsed with water.
Grime from the windshield will stick to the wiper
blades and affect their performance. Clean the
blade by wiping vigorously with a cloth soaked in
full-strength windshield washer solvent. Then rinse
the blade with water.
Check the wiper blades and clean them as
necessary; replace blades that look worn.

Aluminum or Chrome-Plated Wheels

The vehicle may be equipped with either
aluminum or chrome-plated wheels.
Keep the wheels clean using a soft clean cloth
with mild soap and water. Rinse with clean water.
After rinsing thoroughly, dry with a soft clean
towel. A wax may then be applied.
Notice: If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or
cleaners that contain acid on aluminum or
chrome-plated wheels, you could damage the
surface of the wheel(s). The repairs would
not be covered by your warranty. Use
only GM-approved cleaners on aluminum or
chrome-plated wheels.
The surface of these wheels is similar to the
painted surface of your vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because you could damage
the surface. Do not use chrome polish on
aluminum wheels.
Notice: Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
Use chrome polish only on chrome-plated wheels,
but avoid any painted surface of the wheel, and
buff off immediately after application.
