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.
Other features of Active Distance Assist
DISTRONIC:
R Depending on the preselected distance,
DISTRONIC inter venes either dynamically
(short distance) or tosave fuel (long distance).
R Depending on theve hicle mass de tected, the
dynamics of the DISTRONIC inter vention are
re duced.
R The driving style is adap ted depending on the
drive prog ram selected.
R Acceleration tothe stored speed is initiated if
