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 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, the place many GM owners choose
to have their maintenance work done. Your dealer can be relied
upon to use
the proper parts and practices.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps 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.
Recording Maintenance Services
The Maintenance Record near the end of this section 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 the Maintenance
Record.
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 warranty repairs.

If you are skilled enough to do some work on your vehicle, you will
probably want
to get the service information GM publishes. For information
on how to obtain various service publications for your vehicle, see “Service
Publications”
in the Index. You will find a list of publications and an order
form
in the back of the book.
Scheduled Maintenance Services
This part tells you the maintenance services that you should have done and
the times you should schedule them. Your GM 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 the recommended limits. You will
find these limits
on your vehicle’s Certification Label. See “Loading
Your Vehicle”
in the Index.
are driven on regular road surfaces, and within legal driving limits, as
described in Section 4 “Your Driving and the Road.”
are driven off-road in the recommended manner. See “Off Road
Driving With Your Four-wheel Drive Vehicle”
in the Index.
use the recommended fuel. See “Fuel” in the Index.
Selecting the Proper Maintenance Services
To find the proper maintenance schedule for your vehicle, you must know
two things. What engine your vehicle has, and
how you use your vehicle.
Your engine type will tell
you which chart to use, and your driving
conditions will tell
you which schedule to use. The charts are found later in
this section.
Selecting the Proper Maintenance Chart
Your engine type (Gasoline or Diesel) and its emissions classification (Light
Duty or Heavy Duty Emissions) will tell
you which maintenance chart to
use. Find your Vehicle Identification Number (VIN), and look at the eighth
character to see what your engine code
is. Then use the following Engine
Emissions Classifications tables
to find your emissions classification.
0 Your VIN is on the plate on the top left corner of your instrument
panel, the Certification Label and
on the Service Parts Identification
Label. See “Vehicle Identification Number” in the Index.
If your engine has more than one emissions classification, look at your
Certification Label to see what your Gross Vehicle Weight Rating
(GVWR)
is. See “Loading Your Vehicle” in the Index.
