GMC 2007 Savana - Manual (Page 383)

Notice: If you drive your vehicle through an
automatic car wash that has silicone carbide
tire cleaning brushes, you could damage the
aluminum or chrome-plated wheels. The repairs
would not be covered by your warranty. Never
drive a vehicle equipped with aluminum or
chrome-plated wheels through an automatic
car wash that uses silicone carbide tire
cleaning brushes.
Do not take the vehicle through an automatic car
wash that has silicone carbide tire cleaning
brushes. These brushes can also damage the
surface of these wheels.
Tires
To clean the tires, use a stiff brush with tire
cleaner.
Notice: Using petroleum-based tire dressing
products on your vehicle may damage the
paint finish and/or tires. When applying a tire
dressing, always wipe off any overspray
from all painted surfaces on your vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair
shop applies anti-corrosion material to parts
repaired or replaced to restore corrosion protection.
Original manufacturer replacement parts will
provide the corrosion protection while maintaining
the warranty.
Finish Damage
Any stone chips, fractures or deep scratches in
the finish should be repaired right away. Bare
metal will corrode quickly and may develop into
major repair expense.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer.
Larger areas of finish damage can be corrected in
your dealer’s body and paint shop.
