Your Vehicle and the EnvironmcC
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 retailer’s service department or another
qualified service center do these
jobs.
7-2
ProCarManuals.com

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. 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 retailer’s service
department or another qualified service center
should perform.
“Part D: Recommended Fluids and Lubricants” lists
some recommended products to help keep your vehicle
properly maintained. These products,
or their
equivalents, should be used whether you do the work
yourself or have
it clone.
“Part E: Maintenance Record” provides a place lor
you to record the maintenance performed
on your
vehicle. Whenever any maintenance is perfornled, be
sure to write
it down in this part. This will help you
determine when your next maintenance
should be clone.
In acldition, 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 en-ands or
in many other ways.
Because of
all the different ways people use their
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 retailer.
This part tells you the maintenance services you should
have done and
when you should schedule them. If you
go to your retailer 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
Certification/Tire 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:
ProCarManuals.com

Maintenance Schedule
I Short Trip/City Definition
Follow the Short Trip/City Maintenance Schedule if any
one of these conditions is true for your vehicle:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
You operate your vehicle in dusty areas or
off-road frequently.
You frequently tow a trailer or use a carrier on top of
your vehicle.
If
the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooney:
Short Trip/City Intervals
Every 3,000 Miles (5 000 km): Engine Oil and
Filter Change (or
3 months, whichever occurs first).
