Downloaded from www.Manualslib.com manuals search engine 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 it 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.
If you are skilled enough to do some work on your vehicle, you will
probably want to get the service information GM publishes. You will find a
list of publications and how to get them in Section
8, Customer Assistance
Information.
See “Service Publications” in the Index.
The Maintenance Record 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 this section. 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.
