Active Distance Assist DISTRONIC maintains the set speed on free-flowing roads. If vehicles in front are detected, the set distance is maintained, if necessary, until the vehicle comes to a halt. The vehicle accelerates or brakes depending on the distance to the vehicle in front and the set speed. The speed and distance to the vehicle in front are set and saved on the steering wheel on vehicles without the Driving Assistance Package, in the range between 20 km/h and 200 km/h and, on vehicles with the Driving Assistance Package, in the range between 20 km/h and 210 km/h.

Vehicles with Driving Assistance Package: reacts to stationary vehicles detected in urban speed ranges (except bicycles and motorcycles).
Initiates acceleration to the stored speed if the turn signal indicator is switched on to change to the overtaking lane.
Vehicles with Driving Assistance Package: takes one-sided overtaking restrictions into account on motorways or on multi-lane roads with separate carriageways (country-dependent).
Vehicles with Active Parking Assist and Driving Assistance Package: if the vehicle has been braked to a standstill on multi-lane, separate carriageways 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 accelerated any further.
Active Distance Assist DISTRONIC is only an aid. The driver is responsible for keeping a safe distance to the vehicle in front, for vehicle speed and for braking in good time.
In snow, rain, fog, heavy spray, if there is glare, in direct sunlight or in greatly varying light conditions.
The windscreen in the area of the camera is dirty, misted up, damaged or covered.
If the radar sensors are dirty or covered.
In multi-storey car parks or on roads with steep uphill or downhill gradients.
If there are narrow vehicles in front, such as bicycles or motorcycles.
In addition, on slippery roads, braking or accelerating can cause one or several wheels to lose traction and the vehicle could then skid.
Do not use Active Distance Assist DISTRONIC in these situations.
If the vehicle pulls away using Active Distance Assist DISTRONIC.
If the stored speed is called up and is considerably faster or slower than the currently driven speed.
If Active Distance Assist DISTRONIC no longer detects a vehicle in front or does not react to relevant objects.
Active Distance Assist DISTRONIC brakes your vehicle with up to 50 % of the maximum possible deceleration. If this deceleration is not sufficient, Active Distance Assist DISTRONIC alerts you with a visual and acoustic warning.
when driving on a different lane or when changing lanes
to pedestrians, animals, bicycles or stationary vehicles, or unexpected obstacles
to complex traffic conditions
to oncoming vehicles and crossing traffic
As a result, Active Distance Assist DISTRONIC may neither give warnings nor intervene in such situations.
