Plan supplements your new vehicle warranties.
See your Warranty and Owner Assistance booklet
or your dealer for details.
Maintenance Requirements
Notice:Maintenance intervals, checks,

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.
502

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.

Performing maintenance work on a vehicle
