The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, the VDC system helps to perform the
following functions.
.Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
. Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
. Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following
conditions:
— understeer (vehicle tends to not follow
the steered path despite increased
steering input)
— oversteer (vehicle tends to spin due to certain road or driving conditions) .
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.
When the VDC system operates, the VDC

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.
TEMPERATURE A, B AND C
The temperature grades 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 conditions on
a specified indoor laboratory test wheel. Sus-
tained 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 car 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.
