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 uid 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
Aluminum or Chrome-Plated
Wheels and Trim
Your vehicle may have either aluminum or
chrome-plated wheels.
Keep the 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.
Notice:Chrome wheels and other chrome trim may
be damaged if you do not wash your vehicle after
driving on roads that have been sprayed with
magnesium, calcium or sodium chloride. These
chlorides are used on roads for conditions such as
ice and dust. Always wash your vehicle’s chrome
with soap and water after exposure.
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or cleaners
that contain acid on aluminum or chrome-plated
wheels, you could damage the surface of the
wheel(s). The repairs would not be covered by your
warranty. Use only approved cleaners on aluminum
or chrome-plated wheels.

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.
Fiberglass Springs
(Composite Springs)
Notice:If you use acidic or corrosive cleaning
products, engine degreasers or aluminum cleaning
agents on berglass springs, you may damage
the springs. The repairs would not be covered by
your warranty. Use only approved cleaners
when cleaning your vehicle’s berglass springs.
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.

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level and
change as recommended.
Have you purchased the GM Protection Plan? The Plan
supplements your new vehicle warranties. See your
Warranty and Owner Assistance booklet or your
dealer/retailer for details.
Maintenance Requirements
Notice:Maintenance intervals, checks, inspections,
replacement parts, and recommended uids and
lubricants as prescribed in this manual are necessary
to keep your vehicle in good working condition.
Any damage caused by failure to follow scheduled
maintenance might not be covered by warranty.
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 is
important. Improper vehicle maintenance can even affect
the quality of the air we breathe. Improper uid levels or
the wrong tire ination can increase the level of emissions
from your vehicle. To help protect our environment, and
to keep your vehicle in good condition, be sure to
maintain your vehicle properly.
Using the Maintenance Schedule
We want to help you keep your vehicle in good working
condition. But we do not know exactly how you will
drive it. You might drive very short distances only a few
times a 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.
7-2

driving limits.
use the recommended fuel. SeeGasoline Octane
on page 6-5.
The services inScheduled Maintenance on page 7-4
should be performed when indicated. SeeAdditional
Required Services on page 7-5andMaintenance
Footnotes on page 7-6for further information.
{CAUTION:
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs,
you can be seriously injured. Do your own
maintenance work only if you have the required
know-how and the proper tools and equipment
for the job. If you have any doubt, see your
dealer/retailer to have a qualied technician do
the work. SeeDoing Your Own Service Work on
page 6-4.Some maintenance services can be complex.
So, unless you are technically qualied and have
the necessary equipment, you should have your
dealer/retailer do these jobs.
When you go to your dealer/retailer for your service
needs, you will know that trained and supported service
technicians will perform the work using genuine parts.
If you want to purchase service information, seeService
Publications Ordering Information on page 8-16.
Owner Checks and Services on page 7-8tells you
what should be checked, when to check it, and what
you can easily do to help keep your vehicle in good
condition.
The proper replacement parts, uids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 7-11andNormal Maintenance Replacement
Parts on page 7-13. When your vehicle is serviced,
make sure these are used. All parts should be replaced
and all necessary repairs done before you or anyone
else drives the vehicle. We recommend the use of
genuine parts from your dealer/retailer.

Scheduled Maintenance
To maintain the ride, handling, and performance of your
vehicle, it is important that the rst tire rotation service be
performed when you notice unusual wear. Check tires for
ination pressures and wear. SeeTires on page 6-52.If
tire rotation is recommended for your vehicle, rotate tires.
SeeTire Inspection and Rotation on page 6-65.
When the CHANGE OIL NOW message in the Driver
Information Center (DIC) comes on, it means that service
is required for your vehicle. Have your vehicle serviced as
soon as possible within the next 600 miles (1 000 km).
It is possible that, if you are driving under the best
conditions, the engine oil life system may not indicate that
vehicle service is necessary for over a year. However,
your engine oil and lter must be changed at least once
a year and at this time the system must be reset. Your
dealer/retailer has trained service technicians who will
perform this work using genuine parts and reset the
system.
If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 6-20for information on
the Engine Oil Life System and resetting the system.When the CHANGE OIL NOW message appears, the
following services, checks, and inspections are required:
❑Change engine oil and lter. SeeEngine Oil on
