The speed and distance totheve hicle in front are

If a change in the speed limit of 20 km/h or more
is de tected and automatic adoption of speed lim-
its is activated, the new speed limit is automati-
cally adop ted as the stored speed (/ page 211).The driven speed is adjusted when
theve hicle is
le ve l with the tra1c sign at the latest. In the case
of signs indicating entry into an urban area, the
speed is adap ted according tothe speed permit-
te d within the urban area. The speed limit display
in the Instrument Display is alw ays updated when
th eve hicle is le vel with the tra1c sign.
If th ere is no speed restriction on an unlimited
str etch ofroad (e.g. on a mo torw ay),th ere com-
mended speed is automatical lyadop ted as the
stored speed. The system uses the speed stored
on an unlimited str etch ofroad as there commen-
ded speed. If you do not alter the stored speed on
an unlimited str etch ofroad, there commended
speed is 130 km/h.
If Ac tive Distance Assist DISTRONIC has been put
into passive mode bypressing the accelerator
pedal, only speed limits which are higher than the
set speed are adop ted.

When Active Distance Assist DISTRONIC is acti va-
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 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-
tions ahead are take n into account.
Yo u can activate and deactivate route-based
speed adap tation in the multimedia system
(/ page 202).
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-
mation )
% When theto ll station is reached, Active Dis-
ta nce Assist DISTRONIC ado ptsth e speed as

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
tra1c lights, as route-based speed adap tation
does not brake theve hicle toa standstill.
When route guidance is active, the /rst speed
adjustment is car ried out automaticall y.Ifth e turn
signal indicator is switched on, the selected route
is con/rmed and fur ther speed adjustment is acti-

before thero ute event.
R Ifth e driver depresses the accelerator or
brake pedal during the process.
