Ц Push the lever A up towards + or down towards -, fig. 134 in order to increase or reduce the cruising speed setting.
Ц Release the lever to store the current cruising speed.

You can alter the set speed in steps of 1 km/h by briefly pressing the lever upwards or downwards. When you press and hold the lever, the speed is changed in steps of 10 km/h.

You can still use the accelerator pedal to increase speed in the normal way, for example to overtake another vehicle. Once you release the accelerator, the system will revert to the speed you stored initially.

However, if the vehicle exceeds the programmed speed by more than 10 km/h for more than 5 minutes, the cruise control system will be deactivated temporarily. The green symbol in the display will change to white but the stored speed will be retained.
