Part A: Scheduled Maintenance
Services
In this part are scheduled maintenance services which
are to be performed at the mileage intervals specified.

Using Your Maintenance Schedule

We at General Motors want to help 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 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
will know that GM-trained and supported service
people will perform the work using genuine GM parts.

The proper fluids and lubricants to use are listed in
Part C. Make sure whoever services your vehicle uses
these. 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 will find limits on your vehicle's GVW
Rating label. See Loading Your Vehicle on
page 4-30.
•
are driven on reasonable road surfaces within legal
driving limits.
•
use the recommended fuel. See What Fuel to Use
on page 5-6.
