When Active Distance Assist DISTRONIC is acti va-

to thero ute events ahead. Depending on the drive
prog ram selected, theve hicle neg otiates a route
ev ent ahead in an economical, comfor table or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
stored speed. The set distance totheve hicle in
front, vehicles de tected ahead and speed restric-

Yo u can activate and deactivate route-based
speed adap tation in the multimedia system
(/ page 248).
The following route events are take n into account:
R Bends
R T-junctions, roundabouts and toll stations
R Turns and exits R
Tra1c jams ahead (only with Live Tra1c Infor-

% When theto ll station is reached, Active Dis-

Also, the speed is reduced if the turn signal indi-
cator tochange lanes is switched on and one of
th efo llowing situations is de tected:
R Turning o. at junctions
R Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tojunctions, roundabouts and

does not brake theve hicle toa standstill.
