Downloaded from www.Manualslib.com manuals search engine 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.
kerformmg 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 whenever
you stop for fuel. 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.

Services
Using Your Maintenance Schedule
The proper fluids and lubricants to use are 1iste.d 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.
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.
I nese schedules are for vehicles that:
0 carry passengers and cargo within recommended
limits. You
will find these limits on your vehicle’s
CertificatiodTire label. See “Loading Your Vehicle”
in the Index.
0 are driven on reasonable road surfaces within legal
driving limits.
0 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.
