To be sure your locks operate properly, they must be lubricated.
Refer
to the Maintenance Schedule to determine how often to lubricate them
and what type of lubricant to use.
You should not
use penetrating oils because they could wash out the factory
installed lubricant and cause the lock to bind. De-icers which contain
alcohol could also wash away the lubricant,
so be sure to lubricate the lock
after using a de-icer of this type.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle if you notice:
Engine misfiring
Loss of performance
Exhaust system components hanging lower than normal.
Loud exhaust system noises.
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three-way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Engine Control Module System
This system has an oxygen (02) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle. If
you use leaded fuel, you could damage your oxygen
(02) sensor and affect
your vehicle’s emissions.
Malfunction Indicator Lamp (SERVICE ENGINE
SOON)
This light on your instrument panel lets you know when your emission
system needs service. See “Malfunction Indicator Lamp” in the Index.

Downloaded from www.Manualslib.com manuals search engine Underbody Maintenance
Chemicals used for ice and snow removal and dust control can collect on
the underbody. If these are not removed, accelerated corrosion (rust) can
occur
on the underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion protection.
At least every spring, flush these materials from the underbody with plain
water. Clean any areas where mud and other debris can collect. Dirt packed
in closed areas of the frame should be loosened before being flushed. Your
dealer or an underbody vehicle washing system can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a chemical fallout.
Airborne pollutants
can fall upon and attack painted surfaces on your
vehicle. This damage can take
two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into the paint surface.
Although
no defect in the paint job causes this, GM will repair, at no charge
to the owner, the surfaces of new vehicles damaged by this fallout condition
within
12 months or 12,000 miles (20 000 km) of purchase, whichever
comes first.
This applies only to materials manufactured and sold by General Motors.
Bodies, body conversions or equipment not made or sold by General Motors
are not covered.

This section covers the maintenance required for your vehicle. Your vehicle
needs these services
to retain its safety, dependability and emission control
performance.

Introduction
Your Vehicle and the ~ vironment
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 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.

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.
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
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.

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:
