534 SERVICING AND MAINTENANCE
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 vehicle 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, under-inflation, 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 whenever
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 inadvertent 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-ener-
gize the 12 Volt electrical system.
• Serious injury or death could result if you do not
disconnect both batteries. To learn how to properly
disconnect, see your authorized dealer.
