Tempera A, B, 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.
--
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory
to give you the longest tire life
and best overall performance,
In most cases, you will not need to have your wheels
aligned again. However, if
you notice unusual tire wear
or
your vehicle pulling one way or the other, the
alignment may need
to be reset. If you notice your
vehicle vibrating when driving
on a smooth road, your
wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced.
If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
GM dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.

Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the same way as the one it replaces.
If you need to replace any
of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure
to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
CAUTION:
I
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose. control.
You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts for
replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
7
Whenever a wheel, wheel bolt or wheel nut is replaced
on a dual wheel setup, check the wheel
nut torque after
100,
1,000 and 6,000 miles (160, 1 600 and 10 000 km)
of driving. For proper torque, see “Wheel Nut Torque”
in
the Index.
See “Changing a Flat Tire” in the Index for
more information.

Used Replacement Wheels Tire Chains
1
-- 4
Putting a used wheel .on your vehicle is dangerous.
You can’t know how it’s been used or how many
miles it’s been driven.
It could fail suddenly and
cause an accident.
If you have to replace a wheel,
use a new
GM original equipment wheel.
NOTICE:
If your vehicle has dual wheels or P265/75R16
size tires, don’t use tire chains. They can damage
your vehicle.
If you don’t have dual wheels or if you have a tire
size other than P265/75R16, use tire chains only
where legal and only when you must. Use chains
that are the proper size for your tires. Install
them on the tires of the rear axle.
Don’t use chains on the tires of the front axle.
Tighten them as tightly as possible with the ends
,
securely fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can. hear the
chains ‘contacting your vehicle, stop and retighten
them.
If the contact continues, slow dawn until it
stops. Driving too fast or spinning the wheels with
chains on
will damage your vehicle.

Aluminum or Chrome Wheels
(If So Equipped)
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly, dry with a soft clean towel. A wax
may then be applied.
The surface of these wheels is similar to the painted
surface
of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners or
abrasive cleaning brushes
on them because you could
damage
the surface. You may use chrome polish on
chrome wheels, but avoid any painted surface
of the
wheel, and buff
off immediately after application.
Don’t take your vehicle through an automatic
vehicle wash that. has silicon carbide
tire cleaning
brushes. These brushes can also damage
the surface
of these wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
NOTICE:
When applying a tire dressing always take care to
wipe
off any overspray or splash from all painted
surfaces on the body
or wheels of the vehicle.
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.
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.

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:
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.
are driven on reasonable road surfaces within legal
driving limits.
are driven off-road in the recommended manner. See
”Off-Road Driving With Your Four-Wheel-Drive
Vehicle”
in the Index.
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.
