Driving Assistant Plus not only includes Lane Departure Warning, and Approach Warning with City Brake Activation, but also the Active Cruise Control with Stop&Go function.
Active Cruise Control maintains a speed determined by the driver, as well as the distance to the car ahead, at speeds of up to 210 km/h. The vehicle takes over accelerating and braking and keeps the predetermined distance to the car ahead even in slow-moving traffic and down to a stand-still in traffic jams. If a vehicle ahead brakes suddenly, the BMW responds immediately if the Approach Warning is activated. The system operates in steps: A warning symbol is first displayed, then the symbol begins blinking and an acoustic warning is emitted, and finally the brakes are applied.
The system lets the car simply “glide along” with the other cars in dense traffic situations, making traffic jams less stressful. It automatically maintains the desired distance from the vehicle ahead and regulates the car's speed down to standstill.
