The speed adop tedby Active Speed Limit
Assi stmay be too high or incor rect in some
individual cases, su chas:
R at speed limits below 20 km/h

nction of route-based speed adaptation When
Active Dis tance Assi stDISTRONIC is acti‐
va ted, theve hicle speed will be adap ted accord‐
ingly tothero ute events ahead. Depending on
th e drive prog ram selected, theve hicle negoti‐
ates a route event ahead in a fuel-s aving, com‐
fo rtable or dynamic manner. When thero ute
eve nt has been passed, theve hicle accelerates
again tothestored speed. The set dis tance to
th eve hicle in front, vehicles de tected ahead and
speed restrictions ahead are take n into account.
Yo u can activate and deactivate route-based
speed adap tation in the multimedia sy stem
(/ page 200).
The following route events are take n into
account:
R Bends Driving and pa
rking 19 9

R
T-junctions, roundabouts and tollst ations
R Turns and exits
R Traf fic jams ahead (only wi thLive Traf fic
Information )
% 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 indi‐
cator tochange lanes is swit ched on and one of
th efo llowing 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
and traf fic lights, as route-based speed adap ta‐
tion does not brake theve hicle toast andstill.
When route guidance is active, thefirs t speed
adjustment is car ried out automaticall y.Ifthe
turn signal indica tor is switched on, the selected ro
ute is confirmed and fur ther speed adjustment
is activated.
Speed adap tation is cancelled in thefo llowing
cases:
R Ifth e turn signal indicator is switched off
before thero ute event.
R Ifth e driver depresses the accelerator or
brake pedal during the process.
Sy stem limits
Ro ute-based speed adap tation does not take
ri ght of wayre gulations into account. The driver
is responsible for complying with road traf fic
re gulations and driving at a suitable speed.
In dif ficult conditions, the speed selection made
by the sy stem may not alw ays be suitable:
R unclear roads

Ac tive Steering Assist is only available up to a
speed of 210 km/h. The sy stem helps youto

erate steering inter ventions. Depending on the
speed driven, Active Steering Assist uses the
ve hicles ahead and lane markings as a refer‐
