Part A: Scheduled Maintenance 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:
carry passengers and cargo within recommended limits. You will find
these limits on your vehicle's CertificationEire label. See "Loading
Your Vehicle" in the Index.
