Your Vehicle and the Environment
Proper vehicle maintenance not only helps to
keep your vehicle in good working condition, but
also helps the environment. All recommended
maintenance is important. Improper vehicle
maintenance can even affect the quality of the air
we breathe. Improper uid levels or the wrong
tire ination can increase the level of emissions
from your vehicle. To help protect our environment,
and to keep your vehicle in good condition, be
sure to maintain your vehicle properly.
Using the Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we do
not know exactly how you will 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
vehicles, maintenance needs vary. You may
need more frequent checks and replacements.
So please read the following and note how
you drive. If you have any questions on how to
keep your vehicle in good condition, see your
GM Goodwrench
®dealer.

comes on, it means that service is required for
your vehicle. Have your vehicle serviced as
soon as possible within the next 600 miles

under the best conditions, the engine oil life
system may not indicate that vehicle service is
necessary for over a year. However, your engine
oil and lter must be changed at least once a
year and at this time the system must be reset.
