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.

Scheduled Maintenance
When the CHANGE OIL message comes on, it
means that service is required for your vehicle.
SeeDIC Warnings and Messages on page 198.
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 328for information on the Engine Oil Life
System and resetting the system.
When the CHANGE OIL 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.
