TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire's manufacturer
in each category is shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform to Federal safety
requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. 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 charac-
teristics 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 spec
-
ified government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Temperature Grades
The Temperature grades are A (the highest), B, and C, repre -
senting 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.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or peak
traction characteristics.

RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being on in your
vehicle can cause erratic or noisy performance from your
radio. This condition may be lessened or eliminated by relo -
cating the mobile phone antenna. This condition is not
harmful to the radio. If your radio performance does not
satisfactorily “clear” by the repositioning of the antenna, it is
recommended that the radio volume be turned down or off
during mobile phone operation when not using Uconnect (if
equipped).
