Active Distance Assist DISTRONIC maintains the set speed on free-flowing roads. If vehicles ahead 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 (in the range between 20 km/h and 210 km/h) and the distance to the vehicle ahead are set and saved on the steering wheel.
Adjusts the driving style depending on the selected drive program (fuel-saving, comfortable or dynamic) More.
Adjusts the driving style depending on the selected drive program (fuel-saving, comfortable or dynamic) More.
Reacts to stationary vehicles in urban speed ranges if conditions are sufficient to enable detection. The exceptions are bicycles and motorcycles. Pedestrians are also not detected.
Initiates rapid acceleration to the stored speed, if the turn signal indicator is switched on to change to the overtaking lane.
Takes one-sided overtaking restrictions into account on motorways or on multi-lane roads with separate carriageways.
Vehicles with Active Parking Assist: 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.
On slippery roads, braking or accelerating can cause the drive wheels to lose traction and the vehicle could then skid.
In multi-storey car parks or on roads with steep uphill or downhill gradients.
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 line to the vehicle ahead or when changing lanes
to pedestrians, animals, bicycles or stationary vehicles, or unexpected obstacles
to traffic and the surroundings
to oncoming vehicles and crossing traffic
Active Distance Assist DISTRONIC can neither give warnings nor intervene in such situations.
