Active Distance Assist DISTRONIC is only available for vehicles with automatic transmission.
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 and distance to the vehicle in front are set and saved using the cruise control lever. The speed can be set in the range between 20 km/h and 200 km/h.
Depending on the preselected distance, DISTRONIC intervenes either dynamically (short distance) or to save fuel (long distance).
Depending on the vehicle mass detected, the dynamics of the DISTRONIC intervention are reduced.
The driving style is adapted depending on the drive program selected.
Acceleration to the stored speed is initiated if the turn signal indicator is switched on to change to the overtaking lane.
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognise dangers More.
in snow, rain, fog or heavy spray
if there is dirt on the radar sensors or they are covered
if there is interference from radar sources or strong radar reflections, for example in multi-storey car parks
in traffic situations where frequent speed changes are required, e.g. in heavy traffic or on winding roads or off-road
on roads with steep downhill or uphill gradients
on winding roads
The system cannot detect stationary objects unless these were previously detected as moving.
In addition, on slippery or slick roads, braking or accelerating can cause one or several of the drive wheels to lose traction and the vehicle can 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 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.
Active Distance Assist DISTRONIC may not detect narrow vehicles driving in front, e.g. motorcycles or vehicles not travelling in line with your vehicle.
If the following requirements for activation are no longer fulfilled or the system is malfunctioning, Active Distance Assist DISTRONIC is automatically deactivated. If the vehicle is stationary or is moving very slowly during automatic deactivation, the transmission automatically shifts to park position .
