Temperature 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.
These grades are molded on the sidewalls of passenger
car tires.
Whili: the tires available as standard or optional
equipment on General Motors vehicles may vary with
,
respect to these grades, all such tires meet General
Motors performance standards and have been approved
for use
on General Motors vehicles. All passenger type
(P Metric) tires must conform to Federal safety
requirements in addition to these grades.
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 mo,st 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.

Glass
Glass should be cleaned often. GM Glass Cleaner
(GM Part No. 1050427) or a liquid household glass
cleaner will remove normal tobacco smoke and dust
films.
Don’t use abrasive’ cleaners on glass, because they may
cause scratches. Avoid placing decals
on the inside rear
window, since they may have to be scraped
off later. If
abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any temporary license should not.~be attached across the
defogger grid.
Cleaning the Outside of the
Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running, wax
or other material may be on ’the blade or windshield.
Clean the outside of the windshield with
GM
Windshield Cleaner, Bon-Ami Powder@ (GM Part
No. 10500 11). The windshield is clean if beads do not
form when you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked in full strength winqshield washer solvent. Then
rinse the blade with water.
Wiper blades should be checked
on a regular basis and
replaced when worn..
Weatherstrips
..
Silicone grease on ,weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every six
months. During very cold, damp weather
more frequent
application may be required. (See “Recommended
Fluids and Lubricants” in the Index.)
