The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically.
If there is no vehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise
control.
If Distance Pilot DISTRONIC detects a slower-
moving vehicle in front, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving
speed. However, the vehicle is only accelerated
up to the speed you have stored.
Selecting the drive program
Distance Pilot DISTRONIC supports a sporty
driving style if you have selected the Sport or
Sport Plus drive program (
eration behind the vehicle in front or to the set
speed is then noticeably more dynamic. If you
have selected the Comfort drive program, the
vehicle accelerates more gently. This setting is
recommended in stop-and-start traffic.
Changing lanes
If you change to the overtaking lane, Distance
Pilot DISTRONIC supports you if:
you are driving faster than 45 mph (70 km/h)
R
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.

When you change lanes, Distance Pilot
DISTRONIC monitors the right lane (in left-
side traffic) or the left lane (in right-side traf-
fic).

tionary and you do not need to depress the
brake.

the vehicle and relieves the service brake.

your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever.
