1 How This Part 1s Organized
I The remainder of this part is divided into five sections:
“Section
A: Scheduled Maintenance Services” shows what
to have done, and how often. Some
of these services can be
complex,
so unless you are technically qualified and have
the necessary equipment, you should let your dealer’s
service department or another qualified service center do
these jobs.
CAUTION
I-
I
Performing maintenance work on a vehicle can be
6 - dangerous. In trying to do some jobs, you can be I
seriously injured. Do your own maintenance work only
if you have the required know-how and the proper
tools and equipment for the job.
If you have any
doubt, have a qualified technician
do the work.
If you are skilled enough to do some work on your vehicle,
you
will probably want to get the service information GM
publishes.
You will find a list of publications and how to get
them
in this manual. See “Service Publications” in the
Index.
“Section
B: Owner Checks and Services” tells you what
should be checked whenever you stop for fuel. It also
explains what you can easily
do to help keep your vehicle in
good condition.

Maintenance Schedule
Section A: Scheduled Maintenance Services
Using Your Maintenance Schedules
This section tells you the maintenance services you should
have done and when you should schedule them. Your Geo
dealer knows your vehicle best and wants
you to be happy
with it. 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.
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
use the recommended unleaded fuel. See “Fuel” in the
driving
limits.
Index.
Selecting the RiQht 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:
Schedule I
Is any one of these true for your vehicle?
Most trips are less than 4 miles (6 km).
Most trips are less than 10 miles (16 km) and outside
temperatures are below freezing.
The engine is at low speed most of the time (as in
door-to-door delivery, or
in stop-and-go traffic).
You operate your vehicle in dusty areas.
You tow a trailer.
If any one (or more) of these is true for your driving, follow
Schedule
I.
Schedule I1

true.
