ro ute events ahead. Depending on the drive pro‐
gram selected, theve hicle negotiates thero ute
eve nt ahead in a fuel-s aving, com fortable or

re strictions ahead are take n into account.
Ro ute-based speed adjustment can be config‐
ured in the multimedia sy stem (→ page 202).
Ro ute events ahead are:
R Bends
R T-junctions, roundabouts and tollst ations
R Turns and exits
% When theto llst ation is reached, Active Dis‐
ta nce Assi stDISTRONIC adopts the speed as
th estored speed. Also,
the speed is reduced if the turn signal to

lowing situations is de tected:
R Turning off 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
