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 rea\
d 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 re\
moval 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.
rn I CAUTION
I A Performing maintenance work on a vehicle can be dangerous. In
~
If you are skilled enough to do some work on your vehicle, you will probably
want to get the service information
GM publishes. For information on how to
obtain various service publications for your vehicle, see “Se\
rvice Publications” in
the Index. You will find a list of publications and an order form in the back of
the book.
L trying to do some jobs, you can be seriously injured. Do your own
maintenance
work only if you have the required know-how and the
proper tools and equipment for the job. If you have any doubt, have
l a qualified technician do the work.
