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.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. Improper vehicle maintenance can even
affect the quality of the air we breathe. Improper
fluid levels or the wrong tire inflation 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.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended fluids 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.

This part contains engine oil and chassis lubrication
scheduled maintenance which explains the engine
oil life system and how it indicates when to change the

Using Your Maintenance Schedule
We at General Motors want to help you to keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it. You may drive 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 dealer.This part tells you the maintenance services you should
have done and when to schedule them.
When you go to your dealer for your service needs,
you’ll know that GM-trained and supported service
people will perform the work using GM parts.
The properfluids and lubricants to use are listed in
Part D. Make sure whoever services your vehicle uses
them. All parts should be replaced and all necessary
repairs done before you or anyone else drives the
vehicle.
This schedule is for vehicles that:•carry passengers and cargo within recommended
limits. You willfind these limits on your vehicle’s
Certification/Tire label. SeeLoading Your Vehicle
on page 4-29.
•are driven on reasonable road surfaces within
driving limits.
•use the recommended fuel. SeeGasoline Octane
on page 5-4.
