Overview of ACC functions operated with the lever 1 Activate ACC (regulation deactivated) 2 Start control (resume) / increase speed by 1 km/h at a time (sprung position) 3 Interrupt control (sprung position) 4 Deactivate ACC 5 Increase speed by 10 km/h at a time 6 Decrease speed by 10 km/h at a time A Set proximity level B Start control / reduce speed in increments of 1 km/h If the lever is set from the position directly into the sprung position the current speed is stored and the control process is started. Start control Read and observe on page 235 first. Basic requirements for start of control The ACC is activated. selected and the current speed is greater than 30 km/h. position or in the Tiptronic position. Start control › Press the button › or: Set the lever into the sprung position The ACC takes the current driving speed and performs the control, the warn- ing light illuminates in the instrument cluster. If the control is started by moving the lever to the position and should the speed be stored already, the ACC adopts this speed and executes control. Note If control is started at a speed of less than 30 km/h on vehicles with an auto- matic transmission, the speed of 30 km/h is stored. The speed increases auto- matically to 30 km/h or is regulated with respect to the speed of the vehicle ahead. Stop/resume control Read and observe on page 235 first. Stop control › Set the lever into the sprung position › or: Apply the brake. Control stops, the speed remains stored. Resume control › Start control Note Control is also stopped when the clutch pedal is held down for longer than 30 s or the TCS is deactivated. 237 Assist systems |
