Setting speed by the driver
The adaptive cruise control has to be switched on manually at a speed between 30 km/h and 180 km/h. For vehicles with automatic transmission, the automatic selector lever must be in position D or M.
Accelerate to the desired speed and move the thumb wheel to SET/-. The current speed is stored and maintained.
The speed value is indicated in the Driver Information Centre.
The preset speed can then be changed by moving thumb wheel to RES/+ to increase or SET/- to decrease the speed. Move thumb wheel repeatedly to change speed in small steps, move and hold to change speed in large steps.
When the adaptive cruise control is operating, the stop-start system is automatically deactivated.
Adopting speed by the speed limit recognition
The intelligent speed adaptation informs the driver when a speed limit is detected by the speed limit recognition. The detected speed limit can be taken over as new set speed for the adaptive cruise control.
Using the camera at the top of the windscreen, this system detects and reads speed limit and end of speed limit signs.
If the adaptive cruise control is active, the recognised speed limit will be displayed in the Driver Information Centre and MEM illuminates if the difference between set speed and speed limit is more than 9 km/h.
Press MEM on the steering wheel to request saving of the suggested speed.
Press MEM on the steering wheel once more to confirm and save the new speed setting.
This speed limit is now the new set speed of the adaptive cruise control.
The function can be activated or deactivated in the vehicle personalisation.
