112 Driver assist systems ›  Adaptive Cruise Control (ACC) Operation Operating with the lever WARNING Speed range WARNING ACC does not respond to stationary objects or to crossing or oncoming objects. ACC is intended primarily for use on motorways. ACC allows a speed setting in the range of 30-160 km/h. If control is started at a speed of less than 30 km/h on vehicles with an automatic transmission, the speed is automatically increased to 30 km/h or con- trolled according to the speed of the vehicle ahead. The distance to the vehicle ahead can be adjusted to five different levels. Distance level ▶ Maintain a minimum distance in accordance with the country-specific legal regulations. A vehicle with an automatic transmission can be de- celerated to a stop using the ACC and start moving again. Control is disconnected in case of longer hold- ing periods. If your vehicle changes to the fast lane and no vehi- cle is detected in front, ACC accelerates up to the set speed. Automatic stop and start Overtaking › Depress the brake pedal.
