This radar-based cruise control adapts your set speed to the flow of traffic ahead, automatically slowing until your path is clear again. If the vehicle ahead slows to a stop, DISTRONIC PLUS can brake your car to a full halt, then automatically resume when traffic starts moving. For 2014, a new Steering Assist feature helps the driver keep the vehicle centered in its lane while cruising on straight roads or in gentle curves.
