Downloaded from www.Manualslib.com manuals search engine Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary
to remove residue from the paint
finish. You can get GM-approved cleaning products
from your dealer. (See “Appearance Care and Materials”
in the Index.)
Your GM manufactured vehicle may have
a
“basecoat/clearcoat” paint finish. The clearcoat gives
more depth and gloss
to the colored basecoat. Always
use waxes and polishes that are non-abrasive and made
for a basecoat/clearcoat paint finish. Foreign materials such
as calcium
chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage your vehicle’s’finish if they remain on painted
surfaces. Wash the vehicle as soon
as possible. If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their
toll over a period
of years. You can help to keep the paint finish looking
new by keeping your vehicle garaged or covered
whenever possible.
I NOTICE:
Machine compounding or aggressive polishing on
a basecoat/clearcoat paint finish may dull the
finish or leave
swirl marks.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However,
you may use GM Chrome Polish on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim.
To avoid
damaging protective trim, never use auto or chrome
polish, steam
or caustic soap to clean aluminum. A
coating of wax, rubbed to high polish,
is recommended
for all bright metal parts.

Plan
Have you purchased the GM Protection Plan? The Plan
supplements
your new vehicle warranties. See your
Wurranty and Owner Assistance booklet, or your
GM dealer for details.
Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle
in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality
of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase
the level
of emissions from your vehicle. To help protect our
environment, and
to keep your vehicle in good
condition, please maintain
your vehicle properly.
