Spare Tire
Your vehicle, when new, had a fully inflated spare tire.
A spare tire may lose air over time, so check its
inflation pressure reguiariy. See infiation
-- Tire Pressure
on page
5-55 and Loading Your Vehicle on page 4-44
for information regarding proper tire inflation and loading
your vehicle. For instruction on how to remove, install
or store a spare tire, see Changing a Flat Tire
on
page 5-63.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inflated. Have the damaged or flat road
tire repaired or replaced as soon as you can and
installed back onto your vehicle. This way, a spare tire
will be available in case you need it again.
If your vehicle has a spare tire that does not match your
vehicle’s original road tires and wheels in size and
type,
do not include the spare in the tire rotation.

Aluminum Wheels
Keep your 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.
The surface of these wheels is similar
to the painted
surface of your vehicle. Don’t 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.
Don’t take your 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 your tires, use a stiff brush with tire cleaner.
Nofice: When applying a tire dressing, always take
care to wipe
off any overspray or splash from all
painted surfaces on the body
or wheels of the
vehicle. Petroleum-based products may damage the
paint finish and tires.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
appiies anti-corrosion materiai 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 avaliable from your dealer or other service
outlets. Larger areas of finish damage can be corrected
in your dealer’s body and paint shop.
5-83

Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are not
removed, accelerated corrosion (rust) can occur on
the underbody parts such as fuel lines, frame, floor pan
and exhaust system even though they have corrosion protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and debris can collect. Dirt packed in close areas of
the frame should be loosened before being flushed. Your dealer or an underbody car washing system can
do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces
on your vehicle. This damage
can take two forms; blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect in the paint job causes this,
GM will
repair, at no charge
to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.
