Function of Active Speed Limit Assist
If speed limit change between 12 mph
(20 km/h) and 80 mph (130 km/h) is detected
and the automatic adoption of speed limits is
®
active, it will be automatically adopted as the
stored speed ( page 179).
/
The driven speed is adjusted when the vehicle is
level with the traffic sign at the latest. In the
1 up
case of signs indicating entry into an urban area,
the speed is adapted according to the speed
permitted within the urban area. The speed limit
display in the Instrument Display is always upda‐
1 up
ted when the vehicle is level with the traffic sign.
If there is no speed restriction on an unlimited
stretch of road (e.g. on a freeway), the recom‐
mended speed is automatically adopted as the
1 up M.
stored speed. The system uses the speed stored
on an unlimited stretch of road as the recom‐
mended speed. If you do not alter the stored
speed on an unlimited stretch of road, the rec‐
ommended speed is 80 mph (130 km/h).
If Active Distance Assist DISTRONIC has been
put into passive mode by pressing the accelera‐
tor pedal, only speed limits which are higher
than the set speed are adopted.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nize dangers (
