ASC+T/DSC

Highly sensitive sensors monitor the
number of revolutions of the wheels.
When equipped with DSC, they also
monitor steering angle, lateral accelera-
tion, brake pressure and the movement
of the vehicle around its vertical axis.

If differences in the wheel speeds occur,
ASC+T counteracts the danger of
wheelspin by reducing engine torque; if
necessary, ASC will also respond by
applying the brakes to the rear wheels.

In addition, DSC permanently monitors
the vehicle's current operating condition
and compares it with an ideal condition
that is calculated from the sensor's
signals. If deviations from this occur
(understeering or oversteering, for
instance), DSC can stabilize the vehicle
in fractions of a second by reducing
engine output and with the assistance of
braking intervention at individual
wheels. As a result, dangerous skids can
be prevented even as they are just
beginning, but only within the laws of
physics.

You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
drive force and driving stability.

The braking intervention may be
accompanied by sounds specific to the
system.
