With ABC, the suspension struts are positioned between the wheels and the vehicle body. Instead of pneumatic bellows, the system uses a coil spring and a hydraulic cylinder. The hydraulic system is controlled by an electronic unit that analyses numerous sensor signals emitted while the vehicle is moving. ABC is equipped with a self-levelling, speed-dependent adjustment system that slowly lowers the vehicle at higher speeds. The vehicle's level can also be adjusted manually in two stages by pushbutton.
