Distronic is derived from the words "distance" and "electronic". It operates much like a conventional cruise control system. However, when in cruise mode, with Distronic, the system senseds the approach to a slower vehicle and automatically slows the car down to maintain a set following distance.
If the other vehicle speeds up or you switch lanes, the system resumes the original speed setting. The system will apply up to twenty percen of maximum braking force. If more braking is needed, an audible beep and a red warning triangle light on the dash, comes on to alert the driver.
