Introduction
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 can even
affect
the quality of the air we breathe. Improper fluid
levels or the wrong tire inflation
can increase the level
of emissions from your vehicle.
To help protect our
environment, and
to keep your vehicle in good
condition, please maindn your vehicle properly.
How This Section is Organized
The remainder of this section is divided into five parts:
“Part 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.
7-2

A CAUTION:
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you can
be 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. See “Service and Owner Publications” in
the Index.
“Part B: Owner Checks and Services’’ tells you what
should be checked and when. It
also explains what you
can easily
do to help keep your vehicle in good condition. “Part
C: Periodic Maintenance Inspections”
explains
important inspections that your dealer’s service department or another qualified service center should perform.
“Part D: Recommended Fluids and Lubricants” lists
some recommended products 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.
“Part 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 part. 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.

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
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 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.
This schedule
is for vehicles that:

limits. You will find these limits on your vehicle’s

Maintenance Schedule
The services shown in this schedule up to 100,000 miles
(166
OOO km) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at
150,000 miles (240 000 km) should be performed at
the same interval after 150,000 miles
(240 000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
? The US. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform
this maintenance item will not nullify
the emission warranty or limit recall liability prior
to the
completion
of the vehicle’s useful life. We, however,
urge that
all recommended maintenance services be
performed at the indicated intervals and the maintenance be recorded.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show you when to change the engine oil
and filter
-- usually between 3,000 miles (5 OOO km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come
on
before 3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
without
an oil and filter change.
The system won’t detect dust
in the oil. So if you drive
in
a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON light comes on. Remember to reset the
Oil Life Monitor when the oil has been changed. For
more information, see “CHANGE
OIL SOON light”
in the Index.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspections”
in Part C of this schedule.
