To cancel the cruise control, briefly push lever to 
position 3.
When you step on the brake pedal or the vehicle 
speed drops below approx. 25 mph (40 km/h), for 
example when driving upgrade, the cruise control 
will be canceled.
If the illuminated speedometer segments begin to 
blink (e.g. when aquaplaning or when moving the 
gear selector lever to position “N” while driving), the 
cruise control is automatically switched off.
If the cruise control cancels by itself and remains 
inoperative until the engine is restarted, have the 
system checked at your authorized Mercedes-Benz 
Center as soon as possible.4Resume
If the lever is briefly pushed to position 4 when 
driving at a speed exceeding approx. 25 mph
(40 km/h), the vehicle resumes the speed which 
was set prior to the cancellation of the cruise 
control.
The selected speed is shown for approx. 5 seconds 
in the multifunction display, and the corresponding 
speedometer segments from the selected speed to 
the vehicle maximum speed are illuminated.
The last memorized speed is canceled when the 
electronic key in the starter switch is turned to 
position 1 or 0.
Important!
Moving gear selector lever to position “N” switches the 
cruise control off.
