Driving Assistant Plus not only includes the Driving Assistant systems, Lane Departure Warning, and approach control and person warning with light city braking function, but also the active cruise control with Stop&Go function for additional comfort. Active Cruise Control maintains a speed determined by the driver, as well as the distance to the car ahead. In slow-moving traffic or traffic jams, the vehicle takes over accelerating and braking, and the selected distance to the car ahead is maintained down to a stop. If a vehicle ahead brakes heavily, the BMW responds immediately when the Approach Warning is activated. The system operates in steps. A warning icon is first displayed, then the icon begins flashing and an acoustic warning is emitted, and finally the car brakes firmly.
