Highly sensitive sensors monitor the
number of revolutions of the wheels,
steering angle, lateral acceleration,
brake pressure and the movement
of the vehicle around its vertical axis.
If differences in wheel speed should
occur, the system will recognize the
danger this loss of traction causes and
reduce the drive torque going to the
wheels. The system will also apply the
brakes specifically to the rear wheels,
if necessary.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion and compares it with an ideal con-
dition that is calculated from the sen-
sor's signals. If differences such as
under- or oversteering should occur,
DSC will stabilize the vehicle in frac-
tions of a second by reducing engine
power output, applying the brakes to
individual rear wheels Ð and to specific
front wheels, too, if necessary. As a
result, dangerous skids can be pre-
vented even as they are beginning.You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
drive force and vehicle stability.
The braking intervention may be
accompanied by sounds specific to
the system.
The safety belt tensioner responds to
severe frontal collisions by tightening
the belt to ensure that occupants
remain firmly positioned in their seats.
A gas-pressure system retracts the
buckle assembly to tension the shoul-
der and lap belts within fractions of a
second. This reduces the tendency to
slide under the lap belt.
