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 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 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:
0
carry passengers and cargo within recommended
limits. You will find these limits on your vehicle’s
Certification/Tire label. See “Loading Your Vehicle”
in the Index.
are driven on reasonable road surfaces within legal
driving limits.
are driven off-road in
the recommended manner. See
“Off-Road Driving With Your Four-Wheel-Drive
Vehicle’’ in the Index.
use the recommended fuel. See “Fuel” in the Index.

right for your vehicle. Here’s how to decide which
schedule to follow:
