Dynamic Stability Control (DSC) Safety belt tensioner
Highly sensors monitor the number of
revolutions of the wheels, the steering
angle, lateral acceleration, brake pres-
sure and the movement of the vehicle
around its vertical axis.
If differences in the wheel speeds
occur, the system counteracts the
danger of wheelspin by reducing engine
torque. If necessary, the system also
responds with additional braking inter-
vention at all four wheels.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion 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.
You may need some time to become
accustomed to this system intervention.
However, it provides optimum drive
force and vehicle stability.
The braking intervention is accompa-
nied by sounds specific to the system.
The safety belt tensioner responds to
severe frontal collisions by tightening
the belts to ensure that occupants
remain firmly positioned in their seats.
A gas-pressure system retracts the
buckle assembly to tension the
shoulder and lap belts within fractions
of a second. This reduces the tendency
to slide under the lap belt.
