Overview
The airbags located under the marked
covers inflate and unfold in a matter of
a few milliseconds. In this process they
tear through the designed breaking
points of the upholstered covers or
press them out.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
required to inflate the airbags is not
dangerous, and it dissipates together
with the associated smoke.
The entire process is completed within
fractions of a second.
Precision sensors monitor the number of
revolutions of the wheels. When
equipped with DSC, they also monitor
steering angle, lateral acceleration,
brake pressure and the movement of the
vehicle around its vertical axis.
If differences in the wheel speeds occur,
ASC+T recognizes the danger of wheel-
spin and reduces the drive torque. If
necessary, the system also responds
with additional applications of the brakes
at 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 adjusting
engine output and with the assistance of
braking intervention at individual wheels.
Within physically possible limits
dangerous skids can be prevented even
as they are just beginning.
You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
propulsive force and driving stability.
The braking intervention may be accom-
panied by a certain degree of noise.
