The adaptive cruise control uses a radar sensor Fig. 2 which is integrated in the front of the vehicle and is subject to certain system limitations Link. Stationary objects are disregarded.

When there is no traffic in front, the adaptive cruise control works just like a normal cruise control system by maintaining a constant speed. When you draw closer to a vehicle in front, the adaptive cruise control matches your speed to that vehicle by automatically applying the brakes, and then maintains a constant distance (which you can adjust in the settings). As soon as it detects no more vehicles in front, the adaptive cruise control accelerates back up to the cruising speed.

When you switch on the adaptive cruise control, you can set your current speed as the "cruising speed" Link.

While you are driving, you can interrupt the cruise control Link or change the speed setting Link at any time.

In addition, you can adjust the distance to vehicles in front Link and the driving program for the adaptive cruise control Link.
