The system limits of Tra1c Sign Assist apply to
th e de tection of tra1c signs (/ page 255).
Speed limits below 20 km/h are not automatical ly
adop tedby the system as the stored speed. Tem-
porary speed restrictions (e.g. for a cer tain time
or due towe ather conditions) cann otbe proper ly

individual cases, such as:
R at speed limits below 20 km/h

When Active Distance Assist DISTRONIC is activa-
te d, theve hicle speed will be adap ted accordingly
to thero ute events ahead. Depending on the drive
prog ram selected, theve hicle neg otiates a route
ev ent ahead in a fuel-saving, 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-
tions ahead are take n into account.
Ro ute-based speed adap tation can be activa ted in
th e multimedia system (/ page 244).
The following route events are take n into account:
R Bends
R Roundabouts
R T-junctions
R Turns and exits R
Tra1c jams ahead (only with Live Tra1c )
Also, the speed is reduced if the turn signal indi-
cator is switched on and one of thefo llowing sit-
uations 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
tra1c lights, as route-based speed adap tation
does not brake theve hicle toa standstill.
If a cor responding route event is de tected while
ro ute guidance is active, the /rst speed adjust-
ment is car ried out automaticall y.Ifth e turn signal
indicator is switched on, the selected route is
