Driving on busy highways and freeways is more relaxing with Active Cruise Control with Stop & Go function. It not only maintains the desired distance between any vehicles in the lane ahead but also regulates the speed in heavy traffic. Radar sensors at the front of the vehicle permanently scan the road ahead. If your new BMW 3 Series Touring approaches a slower-moving vehicle, the engine control unit and braking system adjust your own speed and ensure that you automatically maintain your distance. If required, such as in congested traffic, the brake is applied to bring the vehicle to a standstill and, depending on the duration of the stop, your BMW will automatically accelerate again. The driver only has to intervene if the vehicle ahead slows down very suddenly. In this case, the Collision Warning with Brake Activation issues optical and acoustic signals prompting the driver to actively apply the brake. If the driver still fails to react, the BMW 3 Series Touring does so, triggering the braking manoeuvre with a deceleration of up to 3m/s². Consequently, BMW ConnectedDrive does not interfere with your driving style until the very last moment – when it’s necessary to prevent an accident. When the lane ahead becomes clear or the vehicle in front speeds up, Active Cruise Control accelerates again until you reach your desired speed. A brief touch on the brake at any time is enough to deactivate the system and allow you to take full control of the vehicle again.
