Have you purchcrsed the GM Protection Plcrn? The Plarz
supplements
your new vehicle warranties. See your
Warranty and Owner Assistance booklet, or your
GM dealer for details.
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.
7-2

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 dealership’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 dealership’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
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:
0 carry passengers and cargo within recommended
limits. You will find these limits
on your vehicle’s
Certificationmire label. See “Loading Your Vehicle’’
in the Index.
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:

Short Trip/City Definition
Follow the Short TripKity Maintenance Schedule if any
one of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).

Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
