A newly developed Mercedes assistance system warns the driver if the car leaves its lane unintentionally. The camera on the inside of the windscreen monitors the road markings and detects when the car leaves its lane. Lane Keeping Assist will be available for the new E-Class and the S-Class from spring 2009.

Lane departure is the cause of one in six serious accidents on German roads. And more than a third of all road users killed here are involved in this type of accident. This is why Mercedes-Benz has developed this new technology – another "forward-looking" assistance system for even safer motoring. This is made possible by a camera on the inside of the windscreen, which can detect road markings by evaluating the difference in contrast between the road surface and the markings.
