Mercedes Benz Wednesday Car Feature: Active Blind Spot Assist

When your vehicle is traveling above approximately 20 mph, this system uses radar technology to sense when a vehicle enters the blind-spot area. Blind Spot Assist then automatically alerts the driver via an illuminated red icon in the appropriate side mirror. The system also gives an audible warning if the driver activates a turn signal while a vehicle is detected in the blind spot. And if you disregard the alerts and begin changing lanes, advanced active technology can apply the brake to a single rear wheel, to help guide the car back into its lane.
