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 section. So please read this section and
note how you drive. If you have any questions on how to keep your vehicle
in good condition, see your GM 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 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.
Recording Maintenance Services
The Maintenance Record near the end of this section provides a place for
you to record the maintenance performed on your vehicle. Whenever any
maintenance is performed, be sure to write it down in the Maintenance
Record. This will help you determine when your next maintenance should be
done, In addition, it is a good idea to keep your maintenance receipts. They
may be needed to qualify your vehicle for warranty repairs.
