Control, refer to page 124.
SPORT Consistently sporty tuning of the shock ab‐
sorbers for greater driving agility.
COMFORT/ECO PRO Balanced tuning of the shock absorbers formore comfort.
Servotronic
The 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.
Furthermore, the steering force adapts accord‐
ing to the driving program, so that a direct,
sporty feel and/or comfortable steering is con‐
veyed.
Variable sport steeringThe 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.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
This results in a sporty steering response. In
addition, it becomes easier to steer during
parking and maneuvering.Seite 123Driving stability control systemsControls123
