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 char-
acteristics and climate.
TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on speci-
fied 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 straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction
characteristics.
TEMPERATURE GRADES
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 condi-
tions 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 tem-
perature can lead to sudden tire fail-
ure. The grade C corresponds to a level
of performance, which all passenger
vehicle tires must meet under the Fed-
eral Motor Vehicle Safety Standard No.
109. Grades B and A represent higher
levels of performance on the labora-
tory 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.

WARNING!
Excessive speed, underinflation, or
excessive loading, either separately
or in combination, can cause heat
buildup and possible tire failure.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than
3 weeks, you may want to take these steps to protect
your battery.
•
Disconnect the negative cable from the battery.
•
Anytime you store your vehicle, or keep it out of ser-
vice (e.g., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system
is started again.
BODYWORK
PROTECTION FROM ATMOSPHERIC
AGENTS
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make
roads passable in snow and ice and those that are
sprayed on trees and road surfaces during other sea-
sons are highly corrosive to the metal in your vehicle.
Outside parking, which exposes your vehicle to airborne
contaminants, road surfaces on which the vehicle is
