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 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 may 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 in ation 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 at General Motors want to help you keep your
vehicle in good working condition. But we do
not know exactly how you will drive it. You may
drive very short distances only a few times a week.
Or you may drive long distances all the time in
very hot, dusty weather. You may use your vehicle
in making deliveries. Or you may 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 may
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
GM Goodwrench
®dealer.
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 Your Vehicle on page 277.
are driven on reasonable road surfaces within
legal driving limits.
use the recommended fuel. SeeGasoline
Octane on page 298.The services inScheduled Maintenance on
page 406should be performed when indicated.
SeeAdditional Required Services on page 409and
Maintenance Footnotes on page 410for 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 GM Goodwrench
®dealer to
have a quali ed technician do the work.
Some maintenance services can be complex.
So, unless you are technically quali ed and have
the necessary equipment, you should have

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 441.
Owner Checks and Services on page 412tells 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 415andNormal
Maintenance Replacement Parts on page 416.
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 ENGINE OIL SOON message
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 314for information on the Engine Oil Life
System and resetting the system.

When the CHANGE ENGINE OIL SOON 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 MaintenanceII
thereafter. However, in some cases,
MaintenanceIImay be required more often.MaintenanceI— Use MaintenanceIif the
CHANGE ENGINE OIL SOON 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
CHANGE ENGINE OIL SOON message comes on
10 months or more since the last service or if
the message has not come on at all for one year.
