Mercedes-Benz Intelligent Drive



COLLISION PREVENTION ASSIST helps the driver to keep a safe distance from the vehicle in front and optimises braking power if the driver does not brake hard enough. 

The system continuously monitors the distance to the vehicle ahead, using visual and audible signals to warn the driver if there is the danger of a collision. If necessary, the Adaptive Brake Assist system will support the driver's braking action and significantly help reduce the risk of an accident.


Protects against rear-end collisions.

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

In urban traffic, on the open road or on the motorway, COLLISION PREVENTION ASSIST can help prevent rear-end collisions in typical driving situations – at speeds of 7 km/h and over.

COLLISION PREVENTION ASSIST uses a mid-range radar sensor to monitor an area approximately 80 m in front of the vehicle. If the minimum safe distance from the vehicle in front is exceeded for a period of several seconds, a red warning light comes on in the instrument cluster. If this distance continues to decrease quickly an intermittent warning tone is emitted.

At the same time, the system activates Adaptive Brake Assist, which automatically increases braking pressure in accordance with the remaining distance in the event that the pressure applied by the driver is insufficient. However, if the driver applies more braking power than the system allows for it is the driver's action that has priority.

The intervention by Brake Assist can be cancelled by the driver by releasing pressure on the brake pedal or pressing down on the accelerator pedal. The braking support is otherwise cancelled by the system once it ceases to detect a situation of danger. The system will not apply the brakes autonomously.

COLLISION PREVENTION ASSIST works discreetly in the background and only becomes noticeable if there is imminent risk of an accident.
