Deactivation of Distronic
Briefly move the distronic control lever in “OFF”
direction (3) – the stored speed remains in the memory
until the electronic key in the starter switch is turned to
position 1 or 0.
Distronic is also deactivated if:
•the service brake pedal is depressed,
•the parking brake is activated,
•the vehicle decelerates to less than approximately
25 mph (Canada: 40 km/h), e.g. while maintaining
the distance to the vehicle ahead,•the gear selector lever is moved to position “N”,
•the electronic stability program (ESP) is active,
•the electronic stability program (ESP) is switched off
manually.
Note:
A signal sounds and the message “DISTRONIC OFF”
appears for 5 seconds in the multifunction display
everytime Distronic is deactivated (except when moving
distronic control lever in “OFF” direction).
Wa r n i n g !
The Distronic switches off and releases the brakes
when the vehicle decelerates below the minimum
speed of 25 mph (Canada: 40 km/h) by operation of
the system. At that time, the driver must apply the
brakes in order to reduce vehicle speed further or
bring it to a stop.
