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 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 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 402.

legal driving limits.

manner. SeeOff-Road Driving on page 368.

Maintenance Footnotes on page 568for further

{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. SeeDoing
Your Own Service Work on page 434.
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

Service Publications Ordering Information on
page 600.
Owner Checks and Services on page 570tells 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 574andNormal
Maintenance Replacement Parts on page 576.
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 449for 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.
563

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 message
comes on 10 months or more since the last
service or if the message has not come on at all
for one year.
