urban speed ranges (except bicycles and
motorcycles)

the turn signal indicator is switched on to

Vehicles with Active Parking Assist and Driv‐
ing Assistance Package: if the vehicle has
been braked to a standstill on multi-lane, sepa‐
rate roadways by Active Distance Assist
DISTRONIC, it can automatically follow the vehi‐
cle 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 vehi‐
cle. The vehicle is not accelerated 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.
