Hella's 24-GHz radar-based lane-change warning system will be featured in the 2009 BMW 7 series. The system warns drivers of vehicles in their blind spots when changing lanes. Once the car reaches 30 mph (48 km/h) or more, the system monitors adjacent right and left lanes. If another vehicle is in a blind spot when the driver is about to change lanes, the system illuminates a symbol in the side mirror and causes the steering wheel to vibrate. The dual warnings enhance the system's overall effectiveness. The sensors have a range of nearly 200 ft (61 m) and work in all weather conditions.
