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.
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 byyour warranty. Never drive a
vehicle equipped with aluminum
or chrome-plated wheels
through an automatic car wash
that uses silicone carbide
tire cleaning brushes.

2008 - Pontiac G8 Owner Manual

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 vehicle warranty.
Finish Damage
Any stone chips, fractures or deep
scratches in the nish 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/retailer.
Larger areas of nish damage can be
corrected in your dealer’s/retailer’s
body and paint shop.
Underbody Maintenance
Chemicals used for ice and
snow removal and dust control can
collect on the underbody. If these
are not removed, corrosion and rust
can develop on the underbody
parts such as fuel lines, frame, oor
pan, and exhaust system even
though they have corrosion
protection.
At least every spring, ush 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 ushed. Your dealer/retailer
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 the vehicle. This damage can
take two forms: blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface.
Although no defect in the paint job
causes this, we 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 rst.

and lubricants as prescribed
in this manual are necessary to
keep your vehicle in good

caused by failure to follow

Your Vehicle and the

Proper vehicle maintenance not only

sure to maintain your vehicle
properly.
Using the Maintenance

We want to help you keep your

week. Or you might drive long
distances all the time in very hot,
dusty weather. You might use your
vehicle in making deliveries. Or
you might drive it to work, to
do errands, or in many other ways.
Because of all the different ways
people use their vehicles,
maintenance needs vary. You might
need more frequent checks and
replacements. So please read the
following and note how you
drive. If you have any questions on
how to keep your vehicle in good
condition, see your dealer/retailer.This schedule is for vehicles that:
carry passengers and cargo
within recommended limits.
You will nd these limits on the
Tire and Loading Information
label. SeeLoading the Vehicle on
page 8-28.
