{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 GM
Goodwrench
®dealer to have a qualied
technician do the work.
Some maintenance services can be complex. So,
unless you are technically qualied and have
the necessary equipment, you should have your
GM Goodwrench
®dealer do these jobs.When you go to your GM Goodwrench
®dealer for
your service needs, you will know that GM-trained
and supported service technicians will perform
the work using genuine GM parts.
If you want to purchase service information, see
Service Publications Ordering Information on
page 497.
Owner Checks and Services on page 470tells 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 473andNormal
Maintenance Replacement Parts on page 475.
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 GM parts.

Scheduled Maintenance
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 GM Goodwrench
®
dealer has GM-trained service technicians who will
perform this work using genuine GM 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. SeeEngine Oil Life System on
page 380for information on the Engine Oil Life
System and resetting the system.
When the CHANGE OIL NOW message appears,
certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst
service be MaintenanceI, your second service be
MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.
465

MaintenanceI— Use MaintenanceIif the
CHANGE OIL NOW message comes on within
10 months since the vehicle was purchased
or MaintenanceIIwas performed.MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever the message
comes on 10 months or more since the last
service or if the message has not come on at all
for one year.

Maintenance Footnotes
(a)A uid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the uid level checked. Add uid
if needed.
(b)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.
(c)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced. Also
look for any opened or broken airbag coverings,
and have them repaired or replaced. The
airbag system does not need regular maintenance.
(d)Lubricate the trunk key lock cylinder. Lubricate
all body door hinges. Lubricate all hinges and
latches, including those for the hood, trunk,
console door, and any folding seat hardware. More
frequent lubrication may be required when
exposed to a corrosive environment. Applyingsilicone grease on weatherstrips with a clean cloth
will make them last longer, seal better, and not
stick or squeak.
(e)If you drive regularly under dusty conditions,
the lter may require replacement more often.
(f)Change automatic transmission uid and lter if
the vehicle is mainly driven under one or more
of these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C) or
higher.
In hilly or mountainous terrain.
Uses such as high performance operation.
(g)Drain, ush, and rell cooling system.
This service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 385 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and ller neck. Pressure test the cooling
system and pressure cap.
469

(h)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(j)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
(k)Drain, ush, and rell intercooler system. This
service can be complex; you should have your
dealer perform this service. See Engine Coolant on
page 385 for what to use. Inspect hoses. Clean
pressure cap and ller neck. Pressure test
the system and pressure cap.
(l)For supercharged engines only: Have your
dealer check the supercharger oil level and add
the proper supercharger oil as needed (or every
36 months, whichever occurs rst). See
Recommended Fluids and Lubricants on page 473.

Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake’s holding ability:
With the engine running and transmission in
NEUTRAL (N), slowly remove foot pressure
from the regular brake pedal. Do this until the
vehicle is held by the parking brake only.
To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to
PARK (P). Then release the parking brake
followed by the regular brake.
