de tected ahead, the set distance is maintained, if
necessary until theve hicle comes toa standstill.
The vehicle accelerates or brakes depending on
th e distance totheve hicle in front and the set
speed. The speed (from 20 km/h) and the dis-
ta nce totheve hicle in front are set and sa ved on
th e steering wheel.
The adjustable set speed can vary due tothefo l-
lowing factors:

the stored limit speed (e.g. winter tyre limit)
(/ page 202)
R The maximum speed recommended byactive
