Ac
tive Dis tance Assi stDISTRONIC maintains the
set speed on free-flowing roads. If vehicles in
front are de tected, the set dis tance is main‐
ta ined, if necessar y,until theve hicle comes to a
halt. The vehicle accelerates or brakes depend‐
ing on the dis tance totheve hicle in front and
th e set speed. The speed (in thera nge between
20 km/h and the maximum design speed) and
th e dis tance totheve hicle in front are set and
sa ve d on thesteering wheel.
The adjus table set speed can vary due tothefo l‐
lowing factors:
R The drive program selected (/ page 169)
R Maximum speed, e.g. winter tyre limit
(/ page 212)
R The maximum speed recommended byactive
ra nge moni toring (depending on equipment
and drive program) (/ page 355)
