If you call up the stored speed and this is lower than your current speed, the vehicle decelerates.
Cruise control is selected.
ESP® must be activated, but not intervening.
The vehicle speed is at least 20 km/h.
The transmission is in position .
The variable limiter is selected.
Switching between cruise control and the variable limiter
Vehicles with Active Distance Assist DISTRONIC: the variable limiter is selected with a different button More.
Activating cruise control or the variable limiter
The current vehicle speed is stored and the vehicle maintains this speed (cruise control) or does not exceed it (variable limiter).
The last stored speed is called up and the vehicle maintains this speed (cruise control) or does not exceed it (variable limiter).
If the last stored speed has previously been deleted, the current vehicle speed is stored.
When you switch off the vehicle, the last speed stored is deleted.
When you activate cruise control or Active Distance Assist DISTRONIC, the last speed stored for the variable limiter is deleted.
Increasing/decreasing the stored speed
The stored speed is increased by 1 km/h.
The stored speed is decreased by 1 km/h.
The stored speed is increased or decreased to the next increment of ten (e.g. to 50 km/h or 60 km/h).
The stored speed is increased or decreased to the next increment of ten and afterwards by increments of 10 km/h.
When the variable limiter is switched to passive mode, you cannot increase or decrease its stored speed in increments of 1 km/h.
Adopting a detected speed
If cruise control/variable limiter is activated and Traffic Sign Assist has detected a speed restriction sign with a maximum permissible speed and this is displayed in the instrument cluster:
The maximum permissible speed shown by the traffic sign is stored and the vehicle maintains or does not exceed this speed.
Deactivating cruise control or the variable limiter
If you brake, deactivate ESP® or if ESP® intervenes, cruise control is deactivated. The variable limiter is not deactivated.
When you switch off the vehicle, the last speed stored is deleted.
When you select cruise control or Active Distance Assist DISTRONIC, the last speed stored for the variable limiter is cleared.
