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 maintain 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.
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 GM publishes. 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 GM dealer’s service
department or another qualified service center
should perform.
“Part
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.
“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 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 GM 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.
These schedules are for vehicles that:

driving limits.
are driven off-road in the recommended manner. See

Vehicle” in the Index.
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:
Gasoline engine vehicles and diesel engine vehicles
have different maintenance requirements. If you have a
diesel engine, follow a schedule designated for diesel
engine vehicles only.
See the Diesel Engine Supplement for diesel engine
maintenance schedules.

The U.S. 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.
# Lubricate the front suspension, kingpin bushings,
steering linkage, transmission shift linkage, transfer case
shift linkage, parking brake cable guides, front axle
propshaft splines and brake pedal springs. Ball joints and kingpin bushings should not
be lubricated unless
their temperature
is 10” F (- 12” C) or higher, or they
could be damaged.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspection” in Part
C of this schedule.
