Maintenance Schedule
Introduction
A Word About Maintenance
We at General Motors want to help you keep your vehicle in
good working condition. But we don't know exactly how
you'll 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 GM vehicles,
maintenance needs vary. You may even need more frequent
checks and replacements than you will find in the schedules
in this part. So please read this part and note how you drive.
If you have any questions on how to keep your vehicle in
good condition, see your Pontiac dealer, the place many GM
owners choose to have their maintenance work done. Your
dealer can be relied upon to use proper parts and practices.
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 procedures are
important. Improper vehicle maintenance or the removal of
important components can significantly affect the quality of
the air we breathe. Improper fluid levels or even the wrong
tire inflation can increase the level of emissions from your
vehicle. To help protect our environment, and to help keep
your vehicle in good condition, please maintain your vehicle
properly.
