Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
If the vehicle in front has been detected and is
shown in the multifunction display, you can
also activate DISTRONIC PLUS when driving
at speeds below 30 km/h. If the vehicle in
front is no longer detected and displayed, for
example because it has changed lanes, DIS-
TRONIC PLUS is deactivated. You will hear a
warning tone if this is the case.

If you do not fully release the accelerator
pedal, the

DISTRONIC PLUS inactive
message appears in the multifunction dis-
play. The set distance to a slower-moving
vehicle in front will then not be maintained.

Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes your vehicle.
It maintains the preset distance to the vehicle
in front.
If DISTRONIC PLUS detects that there is a risk
of a collision, you will be warned visually and
acoustically. Without your intervention, DIS-
TRONIC PLUS cannot prevent a collision. An
intermittent warning tone will then sound and
the distance warning lamp will light up in the
instrument cluster. Brake immediately to
increase the distance to the vehicle driving in
front, or take evasive action, provided it is
safe to do so.
If DISTRONIC PLUS 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.
Changing lanes
If you wish to move into the overtaking lane (in
countries where traffic drives on the right, the
passing lane is the left-hand lane), DIS-
TRONIC PLUS assists you if:
you are driving faster than 60 km/h

If these conditions are met, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
