              The speed limiter is available when driving forwards
              at speeds from approx. 30 km/h (20 mph).

              Driving with the speed limiter
              You can interrupt the speed limiter function at any
              time by fully depressing the accelerator beyond the
              point of resistance. The green indicator lamp

              stored in the memory.
              The speed limiter function is activated again auto-

              If you indicate left (left-hand traffic: indicate right)

              duce the distance from the vehicle in front. Your set

              If ACC does not detect any vehicle in front after you
