Changing lanes
If when driving on multilane roads you wish to
change to the overtaking lane, Distance Pilot
DISTRONIC supports you if:
you are driving faster than 45 mph (70 km/h)
R
Distance Pilot DISTRONIC is maintaining the
R
distance to a vehicle in front
you switch on the appropriate turn signal
R
Distance Pilot DISTRONIC does not currently
R
detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
i
When you change lanes, Distance Pilot
DISTRONIC monitors the left lane (on left-
hand-drive vehicles) or the right lane (on right-
hand-drive vehicles).
