Downloaded from www.Manualslib.com manuals search engine Uniform Tire Quality Grading
The following information relates to the system developed by the United
States National Highway Traffic Safety Administration which grades tires
by treadwear, traction and temperature performance. (This applies only to
vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the
tire when tested under controlled conditions on a specified government test
course. For example, a tire graded
150 would wear one and a half (1 112)
times as well on the government course as a tire graded 100. The relative
performance
of tires depends upon the actual conditions of their use,
however, and may depart significantly from the norm due to variations in
driving habits, service practices and differences in road characteristics and
climate.
Traction -A, By C
The traction grades, from highest to lowest are: A, B, and C. They represent
the tire’s ability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and concrete.
A
tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight-ahead) traction tests and does not include cornering (turning)
traction.
Temperature - A, 9, C
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause the material
of the tire to
degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade
C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you have aluminum wheels, don’t use an automatic vehicle
wash that has hard silicon carbide cleaning brushes. These
brushes can take the protective coating
off your aluminum
wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
When applying a tire dressing always take care to wipe
off any overspray or
splash from painted surfaces. Petroleum-based products may damage the
paint finish.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal repair or replacement,
make sure the body repair shop applies anti-corrosion material to the parts
repaired or replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents, road oil and tar, tree
sap, bird droppings, chemicals from industrial chimneys, and other foreign
matter can damage your vehicle’s finish if they remain on painted surfaces.
Use cleaners that are marked safe for painted surfaces to remove foreign
matter.
Finish Damage
Any stone chips, fractures or deep scratches in the finish should be repaired
right away. Bare metal will corrode quickly and may develop into a major
repair expense.
Minor chips and scratches can be repaired with touch-up materials available
from your dealer or other service outlets. Larger areas of finish damage can
be corrected in your dealer’s body and paint shop.

0 TESTVNXX3XXQ09696 0 11
This is the legal identifier for your vehicle. It appears on a plate in the front
corner of the instrument panel, on the driver's side. You can see it if you
look through the windshield from outside your vehicle. The VIN also
appears on the Vehicle Certification and Service Parts labels and the
certificates
of title and registration.
Engine Identification
The eighth character in your VIN is the engine code. This code will help
you identify your engine, specifications, and replacement parts.

You’ll find this label on the inside of the glove box.
It’s very helpful
if you ever need to order parts. On this label is:
your VIN,
0 the model designation,
0 paint information, and
0 a list of all production options and special equipment.
Be sure that this label is not removed from the vehicle.
Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle unless you check
with your dealer first. Some electrical equipment can damage
your vehicle and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can keep other components from working as they should.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from short circuits by a
combination of fuses, circuit breakers, and fusible thermal links in the
wiring itself. This greatly reduces the chance of fires caused by electrical
problems.

This section covers the maintenance required for your vehicle. Your vehicle
needs these services
to retain its safety, dependability and emission control
performance.
Have you purchased the GM Protection Plan.? The Plan sctpplem.ent,s yo~~r
new vehicle warranties. See your GM dealerafor detuils.
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.

Downloaded from www.Manualslib.com manuals search engine 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 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:
