Ergonomics and safety

On the lookout.

The high-beam assistant in the BMW 3 Series Touring.

Adding to your safety, the high-beam assistant gauges the driving conditions around you and, if it is necessary, it turns your car's high-beam lights on and off by itself. When the system is activated, an image sensor mounted on the inside of the front mirror checks the traffic and light conditions. Using the resulting images, this assistant decides if high-beam lights are needed. In oncoming traffic, when you are driving behind another vehicle, or if the ambient light is strong enough, the high-beam assistant turns off the high-beam headlights.  (standard option only in the 335i)
