Risk of accident
The vehicle can be braked when DISTRONIC
PLUS is activated. For this reason, deactivate
DISTRONIC PLUS if the vehicle is to be set in
motion by othe rmeans (e.g. in acar wash or
by towing).
You can activate DISTRONIC PLUS in the fol-
lowing circumstances:
R if the engine has been started and you have
been drivin gfor up to two minutes
R if the parkin gbrake is not applied
R if ESP ®
is acti vated
R if the transmission is in position D
R if the bonnet is closed
R if the driver' sdoor is closed and you shift
from Pto Dor your seat belt is fastened
R if the front-passenger door is closed
Activating while driving
When drivin gatspeeds below 30 km/h, you
can only acti vate DISTRONIC PLUS if the vehi-
cle in fron thas been detected and is shown
in the multifunction display. If the vehicle in
front is not shown in the multifunction display
and is no longe rbeing detected, because it
has changed lanes, for example, DISTRONIC
PLU Sisd eactivated and atone sounds. 162
