system in your vehicle needs refrigerant, be sure the proper refrigerant is
used. If you’re not sure, ask your
GM dealer. For additional information, see

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 A d The Environment
Proper vehicle mainte nce not only helps keep your vehicle in good
working condition, bur
11 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.
