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 283).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 driver's display is alw ays updated when the
ve hicle is le vel with the tra1c sign.
If yo u are driving on German mo torw ays and there
is no speed limit, the system uses the speed
stored for a str etch ofroad with no speed limit as
th e set speed. If you do not alter the stored speed
on a str etch ofroad with no speed limit, there c-
ommended speed of 130 km/h is adop ted.
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.
The maximum permissible speed does not take
