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.
Excessive speed, underinflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.

STORING THE VEHICLE

WARNING!
Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is ON. You can be injured by moving
fan blades.
Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadver-
tent electrical contact. You could be seriously
injured.
Vehicles with the Stop/Start system will be
equipped with two batteries. Both the main and
the supplemental batteries must be disconnected
to completely de-energize the 12 Volt electrical
system.
SERVICING AND MAINTENANCE
Serious injury or death could result if you do not
disconnect both batteries. To learn how to properly
disconnect, see an authorized dealer.
If the negative battery cables are not isolated prop-
erly it can cause a potential power spike or surge in
the system, resulting in damage to essential electrical
components.
If you are storing your vehicle for more than three
weeks, we recommend that you take the following steps
to minimize the drain on your vehicle's battery:
Disconnect the negative cable from battery.
If your vehicle is equipped with Stop/Start system
then disconnect both the main and supplemental
negative battery cables.
Any time you store your vehicle or keep it out of ser-
vice (i.e., 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.
If assistance is needed to disconnect the battery
system, see an authorized dealer.
