Services
Using Your Maintenance Schedule
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
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 you 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 fluids 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:
carry passengers and cargo within recommended
limits.
You will find these limits on your vehicle’s
Certificationmire label. See “Loading Your Vehicle”
in the Index.
are driven on reasonable road surfaces within legal
driving limits.
0 use the recommended fuel. See “Fuel” 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
schedule to follow:

The services shown in this schedule up to 100,000 miles
(166 000 km) should be performed after 100,000 miles
(166 000 km) at the same intervals. The services shown
at 150,000 miles
(240 000 km) should be performed at
the same interval after 150,000 miles (240 000 km).
See “Owner Checks and Services’’ and “Periodic
Maintenance Inspections” following.
Footnotes
The U.S. Envlronmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will
not nullify
the emission warranty or limit recall liability prior to the
completion
of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
# Lubricate the front suspension, ball joints and kingpin
bushings, steering linkage and transfer case shift linkage,
parking brake cable guides, and brake pedal springs.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspections” in Part
C of this schedule.

Lubricants”
in the Index for proper lubricant to use):

fluid as needed at every oil change. If driving in
dusty areas or towing a trailer, drain fluid and refill
every 15,000 miles
