Supports the driver when accelerating, braking, maintaining distances, and with steering in the range of 0–155mph.* Within the system limits, the system detects the lane markings, structures next to the road, vehicles in adjacent lanes and multiple vehicles ahead. The system can be adjusted in single and 6mph increments between 19mph and 155mph.* The included bottleneck assist provides support in narrow passing lanes, such as motorway roadworks. The system will keep the vehicle in the centre of the lane and maintain speed and distance, or adjust the speed to the situation. This is all made possible by the radar sensor, laser scanner, front camera and ultrasonic sensors that permanently monitor the vehicle surroundings. Using information such as speed restrictions, the MMI Navigation Plus with MMI Touch uses the data from the predictive efficiency assistant to control speed even when there are no vehicles ahead, encouraging economical driving.
