Finish Care
Occasional waxing or mild polishing of the vehicle by
hand may be necessary to remove residue from the
paint finish. Approved cleaning products can be
obtained from your dealer/retailer.
If the vehicle has 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.
Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint finish may
damage it. Use only non-abrasive waxes and
polishes that are made for a basecoat/clearcoat
paint finish on the vehicle.
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 the 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. To help keep the paint finish looking new, keep
the vehicle garaged or covered whenever possible.
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, chrome polish may be used 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.
Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer fluid or a mild
detergent. Wash the windshield thoroughly when
cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
.Extreme dusty conditions
.Sand and salt
.Heat and sun
.Snow and ice, without proper removal

At your General Motors dealer/retailer, you can be
certain that you will receive the highest level of service
available. Your dealer/retailer has specially trained
service technicians, uses genuine GM replacement
parts, as well as, up to date tools and equipment to
ensure fast and accurate diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 8‑10andMaintenance Replacement Partson
page 8‑12. We recommend the use of genuine parts
from your dealer/retailer.
Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). See Tire Inspection
and Rotation on page 7‑70.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 7‑15. An Emission Control Service.
When the Change Engine Oil Soon message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset.
Your dealer/retailer has trained service technicians
who will perform this work and reset the system. If the
engine oil life system is reset accidentally, service the
vehicle within 5 000 km/3,000 miles since the last
service. Reset the oil life system whenever the oil is
changed. See Engine Oil Life System on page 7‑18.
When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.
