This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.

The system offers several different programs.
The programs can be selected via Driving Dy‐
namics Control.

Variable sport steering
▷
Green: the system is actively
braking the vehicle.
The variable sport steering increases the
steering angle of the front wheels at large
steering wheel angles, e.g., in tight curves or
when parking. Steering becomes more direct.
▷
Orange: the system is on
standby.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
Malfunction
A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
This results in a sporty steering response. In
addition, it becomes easier to steer during
parking and maneuvering.

Program
Concept
The Servotronic varies the steering force re‐
quired to turn the wheels in accordance with
the vehicle speed. At low speeds, the steering
force is strongly supported, i. e. during steer‐
ing, low force is required. As the speed in‐
creases, the assistance of the steering force is
reduced.
