If speed limit change between 20 km/h and
13 0 km/h is de tected and the automatic adop‐
tion of speed limits is active, it will be automati‐ cally adop
ted as thestored speed
(/ page 236).
The driven speed is adjus ted when theve hicle is
le ve l with the traf fic sign at the latest. In the
case of signs indicating entry into an urban area,
th e speed is adap ted according tothe speed
permitted within the urban area. The speed limit
display in the driver display is alw ays updated
when theve hicle is le vel with the traf fic sign.
If yo u are driving on German mo torw ays and
th ere is no speed limit, the sy stem uses the
speed stored on an unlimited stre tch of road as
th ere commended speed. If you do not alter the
st ored speed on an unlimited stre tch of road, the
re commended speed is 130 km/h.
If Ac tive Dis tance Assi stDISTRONIC has been
put into passi vemode bypressing the accelera‐
to r pedal, only speed limits which are higher
th an the set speed are adop ted.
The maximum permissible speed does not take
th ero ad condition and cur rent we ather and traf‐
fi c conditions into account. Adjust your speed
accordin gly, when necessar y. Obser
vethe no tes on driving sy stems and your
re sponsibility; you may otherwise failto recog‐
nise dangers (/ page 219).
