If a vehicle is detected ahead, those segments in the
speedometer dial light up that indicate the speed range
from the speed of the vehicle in front up to the Distronic
stored speed.
When the vehicle in front can no longer be detected,
only the segments around the stored speed light up. The
vehicle is accelerated to the stored speed.
