Ac tive Distance Assist DISTRONIC maintains the
set speed on free-0owing roads. If vehicles ahead
are de tected, the set distance is maintained, if
necessary until theve hicle comes toa halt. The
ve hicle accelerates or brakes, depending on the
distance totheve hicle in front and the set speed.
The speed and distance totheve hicle in front are
set and sa ved using the cruise control le ver.The
speed can be set in thera nge between 20 km/h
and 200 km/h.

R Depending on the preselected distance,
DISTRONIC inter venes either dynamically
