Maintenance Schedule
Introduction: A Word about Maintenance
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 will
find in the schedules
in this part. So
please read this part and note how you
drive. If you
have any questions on how
to keep your vehicle
in good condition,
see your Geo dealer, the place many
GM
owners choose to have their maintenance
work done. Your dealer can be relied
upon to use proper parts and practices.
Your Vehicle and the
Environment
Proper vehicle maintenance not only
helps to keep your vehicle
in good
working condition, but also helps the
environment. All recommended
maintenance procedures are important.
Improper vehicle maintenance or the
removal of important components can
significantly affect the quality of the air
we breathe. Improper fluid levels or even
the wrong tire inflation can increase the
level of emissions from your vehicle.
To
help protect our environment, and to help
keep
your vehicle in good condition,
please maintain your vehicle properly.
How This Part is Organized
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.
f you are skilled enough to do some
work on your vehicle, you will probably
want to get the service information
SM publishes. You will find a list of
wblications and how to get them in this
nanual. See “Service Publications”
in
he Index.
‘Section B: Owner Checks and Services”
ells you what should be checked
whenever you stop for fuel. It also
:xplains what you can easily do to help
:eep your vehicle in good condition.

ProCarManuals.com

“Section C: Periodic Maintenance
Inspections” explains important inspections that your Geo dealer’s service
department or another qualified service
center should perform.
“Section
D: Recommended Fluids and
Lubricants” lists some products GM
recommends to help keep your vehicle
properly maintained. These products, or
their equivalents, should be used whether
you do the work yourself or have it done.
“Section
E: Maintenance Record”
provides a place for you to record the
maintenance performed on your vehicle.
Whenever any maintenance is performed,
be sure to write it down in this section.
This will help you determine when your
next maintenance should be done.
In
addition, it is a good idea to keep your
maintenance receipts. They may be
needed to qualify your vehicle for
warranty repairs.
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 knoN
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 driving limits.
use the recommended unleaded 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:
Schedule

Most trips are less than 10 miles
(1
6 km) when 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 or off-road frequently.
D You tow a trailer.
[f any one (or more) of these is true for
your driving, follow Schedule I.
Schedule
I1
Follow Schedule I1 on& if none of the
lbove conditions
is true.

uneven wear or damage.
If you
see irregular or premature wear,
check the wheel alignment.
Check for damaged wheels also.

corrosion inhibitor level and
maintains proper engine

Inspect hoses and replace
if
they are cracked, swollen or
deteriorated. Tighten screw-type
hose clamps. Clean the outside
