Plan
Have you purchased the GM Protection Plan? The
Plan supplements your
new vehicle warranties. See
your Buick dealer for details.
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 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
Buick 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.
