The following function is country-dependent and only available in conjunction with the Driving Assistance Package.
When Active Distance Assist DISTRONIC is activated, the vehicle speed will be adjusted accordingly to the route events ahead. Depending on the drive program selected, the vehicle negotiates a route event ahead in a fuel-saving, comfortable or dynamic manner. When the route event has been passed, the vehicle accelerates again to the stored speed. The set distance to the vehicle in front, vehicles detected ahead and speed restrictions ahead are taken into account.
Route-based speed adaptation can be configured in the multimedia system More.
Bends
T-junctions, roundabouts and toll stations
Turns and exits
When the toll station is reached, Active Distance Assist DISTRONIC adopts the speed as the stored speed.
Turning off at junctions
Driving on slowing-down lanes
Driving on lanes adjacent to slowing-down lanes
The driver is responsible for choosing the right speed and observing other road users. This applies in particular to junctions, roundabouts and traffic lights, as route-based speed adaptation does not brake the vehicle to a standstill.
When route guidance is active, the first speed adjustment is carried out automatically. If the turn signal indicator is switched on, the selected route is confirmed and further speed adjustment is activated.
If the turn signal indicator is switched off before the route event.
If the driver depresses the accelerator or brake pedal during the process.
Route-based speed adaptation does not take right of way regulations into account. The driver is responsible for complying with road traffic regulations and driving at a suitable speed.
In difficult conditions, for example unclear roads, lane narrowing, wet road surfaces, snow or ice, or when driving with a trailer, the speed adjustment made by the system may not always be suitable. In these situations the driver must intervene accordingly.
Route-based speed adjustment might malfunction or be temporarily unavailable in the following situations:
If map data is not up to date or available
If you do not follow the selected route guidance
If the set route is re-planned
In road construction areas
When towing a trailer
In bad weather or road conditions
If the accelerator pedal is depressed
