Part A: Scheduled Maintenance
Services
Using Your Mair mce Schedule A - --
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 LIS~ their GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements
than you'll 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.
This part tells
you the maintenance services YOLI should
have done and when
you should schedule them. If you
go to your dealer for your service needs, you'll know
that GM-trained
and supported service people will
perform the work using genuine
GM parts. The
proper tluids and lubricants
to use are listed in Part D.
Make sure whoever services your vehicle uses these. All
parts should be replaced and all necessary repairs done
before
you or anyone else drives the vehicle.
These schedules are
for vehicles that:
a
a

limits. You
will find these limits on your vehicle's
Certification/Tire label. See "Loading Your Vehicle"
in the Index.

Selecting the Right Schedule
First you'll need to decide which of the two schedules is
right for your vehicle. Here's how
to decide which
