BMW 5 Series: Collision Warning
The camera-based collision warning is part of the Active Driving Assistant optional equipment (OE 5AS) in the G30 and is implemented using the KAFAS stereo camera.
The collision warning in the new BMW 5 Series contains the familiar Frontal Collision Warning with City Collision Mitigation and Daytime Pedestrian Protection functions.
In vehicles with the Active Driving Assistant Plus optional equipment (OE 5AT), the cruise control radar sensor is also used to control the collision warning.

Vehicles with the Active Driving Assistant Plus optional equipment (OE 5AT) have the Active Cruise Control with Stop&Go function integrated as standard.
The system warns the driver in situations where a collision is imminent. The early warning, a visual signal, is issued first to draw the driver's attention to the situation. If the situation becomes more critical, an acute early warning in the form of a visual and acoustic signal is issued. The nature of the warning is such that the driver can still prevent a collision providing he acts quickly.
The collision warning is dependent on the vehicle's own driving speed. The distance measured for the collision warning is significantly lower than the legally required minimum distance. It is therefore the responsibility of the driver to adhere to the legal minimum distance.

It was possible to carry over the active air-flap control from the G12. The
cooling surfaces at the front
of the vehicle can be closed by means of two separate air flaps. This reduces
the drag coefficient and
thus saves fuel. A further advantage is faster heating up of the engine after a
