Supports the driver when accelerating, braking and maintaining distances in the range of 0-155mph. Within system limits, the system detects lane markings, structures next to the road, vehicles in adjacent lanes and multiple vehicles ahead. The system will maintain speed and distance, or adjust speed to the situation, all made possible by the radar sensor, front camera and ultrasonic sensors. In combination with the Predictive efficiency assistant the car uses data from the MMI Navigation to control speed even with no vehicles ahead to encourage economical driving.
