ted.

Vehicles with Driving Assistance Package
and Traffic Sign Assist: Active Distance Assist
DISTRONIC also has the Active Speed Limit
Assist function. This function can be configured
in the multimedia system. If a change in the
speed limit is detected and Active Distance
Assist DISTRONIC is activated, Active Distance
Assist DISTRONIC assumes this new speed.
The driven speed is adapted when the vehicle is
level with the traffic signs. The speed limit dis‐
play in the Instrument Display is always updated
when the vehicle is level with the traffic sign.
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.
Pulling the cruise control lever will set the dis‐
played speed limit as the speed, provided that:
R
Active Speed Limit Assist has been activated
in the multimedia system and
R
Active Distance Assist DISTRONIC has been
activated.
If no speed limit is displayed when the lever is
operated, the speed set by the driver is adopted.
Drive program
The DYNAMIC SELECT switch allows you to
change the driving style of Active Distance
Assist DISTRONIC. Depending on which drive
program is selected, the driving characteristics
can be geared towards fuel economy, comfort or
dynamic performance (
