Part A: Scheduled Maintenance
Services
Using Your M ’,--lawe 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 retailer.
This part tells you the maintenance services you should
have done and when you should schedule them. If you go to your retailer 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
Tire-Loading Information label. See “Loading Your
Vehicle” in the Index.
0 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:
7-4

Maintenance Schedule
I Short TripKity Definition I
Follow the Short TripKity Maintenance Schedule if any
one of these conditions
is true for your vehicle:
0 Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as fiequent
driving in stop-and-go traffic).
0 Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down soonex
or other commercial application.
