Mercedes-Benz Intelligent Drive

Active Blind Spot Assist


The system indicates in the exterior mirror if cars or motor bikes are present in the blind spot and, if there is a danger, e.g. when changing lanes, it will automatically take countermeasures.

No-one can see what is behind them. In a vehicle, this has traditionally been compensated for by using the rear-view and exterior mirrors. However, there is still an area which cannot be seen even when using a mirror: the blind spot.


What happens in the blind spot is often overlooked and can quickly become dangerous. Mercedes-Benz Active Blind Spot Assist supports the driver in monitoring areas that are difficult to see. It warns against any dangers detected and can help to prevent accidents by selective brake interventions.

Detailed information


Changes may have been made since these images and films were produced.

The warning range of the assistance system covers an area extending approximately 3 m to the right and to the left of the vehicle and 3 m to the vehicle rear. 

The warning also includes vehicles which change lanes from two lanes away to the adjacent lane and thus, into the warning range. Vehicles which are overtaking are displayed as soon as they enter the monitored zone. Vehicles which have just been overtaken are displayed about 1.5 sec after entering the zone. This way, a permanent flashing signal is avoided when overtaking a convoy of vehicles and the acoustic warning plus flashing signal when your vehicle re-enters its lane is suppressed.
