SERVICING AND MAINTENANCE 445
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.
STORING THE VEHICLE
If the vehicle should remain stationary for more than a
month, observe the following precautions:
• Park your vehicle in a covered, dry and possibly airy loca-
tion the windows open slightly.
• Check that the Electric Park Brake is not engaged.
• Disconnect the negative (-) terminal from the battery post
and be sure that the battery is fully charged. During
storage check battery charge quarterly.
• If you do not disconnect the battery from the electrical
system, check the battery charge every 30 days.
• Clean and protect the painted parts by applying protective
waxes.
• Clean and protect polished metal parts by applying
protective waxes.
• Apply talcum powder to the front and rear wiper blades
and leave raised from the glass.
• Cover the vehicle with an appropriate cover taking care
not to damage the painted surface by dragging across dirty
surfaces. Do not use plastic sheeting which will not allow
the evaporation of moisture present on the surface of the
vehicle.
• Inflate the tires at a pressure of +7.25 psi (+0.5 bar) higher
than recommended on the tire placard and check it period-
ically.
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.
