age: takes one-sided overtaking restrictions
into account on highways or on multi-lane

Vehicles with Active Parking Assist and Driv‐
ing Assistance Package: if the vehicle has
been braked to a standstill on multi-lane, struc‐
turally separate roadways by Active Distance
Assist DISTRONIC, it can automatically follow
the vehicle in front driving off again within
30 seconds. If a critical situation is detected
when driving off, a visual and acoustic warning is
given indicating that the driver must now take
control of the vehicle. The vehicle is not acceler‐
ated any further.
Active Distance Assist DISTRONIC is only an aid.
The driver is responsible for keeping a safe dis‐
tance to the vehicle in front, for vehicle speed
and for braking in good time.
