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
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 inc\
rease 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 for warranty repairs.
CAUTION
+ 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 aualified 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 the back of Section
8, “Customer
Assistance Information.” See “Service Publications’’ in the Index.

Scheduled Maintenance Services
Scheduled Maintenance Services
This part tells you the maintenance services that you should h\
ave 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 peop\
le will perform

“Off Road Driving With Your Four Wheel Drive Vehicle.”
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 ve\
hicle. Your
engine type will tell you which chart to use, and your drivin\
g 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 classificat\
ion (Light
Duty 3r Heavy Duty Emissions) will tell you which maintenance \
chart
to use.
Find your Vehicle Identification Number (VIN), and look at th\
e eighth character
to see what your engine code is. Then use the following Engine E\
missions
Classifications table
to find your emissions classification.
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 Ratin\
g
(GVWR)
is. See “Loading Your Vehicle” in the Index.
