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 Oldsmobile retailer. 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.
are driven on reasonable road surfaces within legal
driving limits.
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:
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.

Maintenance Schedule
Short Trip/City Definition

one of these conditions is true for your vehicle:

temperatures are below freezing.
0 Most trips include extensive idling (such as frequent
driving
in stop-and-go traffic).
Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
0 If the vehicle is used for delivery service, police, taxi
your vehicle.
or other commercial application.
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 sooner
