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 che~ks 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 Chevrolet dealer, the
place many GM owners choose to have their maintenance
work done. Your dealer cq 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 woxking 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
vehicIe.
To help protect our environment, and to help keep
your vehicle in good condition, please maintain your vehicle.
properly.
