R
you have switched on the corresponding
turn signal.
R DISTRONIC PLUS
does not 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.
Vehicles with COMAND
i The following function is not operational
in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
react appropriately to certain traffic
situations. This is the case if, while following
a vehicle, DISTRONIC PLUS is active and you:
R approach or drive through a traffic circle
R approach a T intersection
R turn off at a freeway exit
Even if the vehicle in front leaves the
detection range, DISTRONIC PLUS
temporarily maintains the current driving
speed and does not accelerate. This is based
on the current map data in the navigation
system. Example: traffic circle
The current speed is maintained:
R
approximately ten seconds before the
traffic circle/T intersection and for approximately 1.5seconds
when driving on
the traffic circle
R approximately twelve seconds before
reaching a freeway exit and approximately
four seconds after the freeway exit
Afterwards, the vehicle accelerates back to
the set speed you specified.
Stopping G
WARNING
Never get out of the vehicle when DISTRONIC
PLUS is activated.
DISTRONIC PLUS must also never be
operated, activated or deactivated by a
passenger or from outside the vehicle.
DISTRONIC PLUS does not replace the
electric parking brake and must not be used
for parking.
The DISTRONIC PLUS braking effect is
canceled and the vehicle can start moving if:
R DISTRONIC PLUS is deactivated using the
cruise control lever.
R you accelerate.
R there is a malfunction in the system or an
interruption in the power supply, e.g.
battery failure.
R the electrical system in the engine
compartment, the battery or the fuses are
tampered with.
R the battery is disconnected.
If you wish to leave the vehicle or park it,
deactivate DISTRONIC PLUS and secure the
vehicle against rolling away.
If DISTRONIC PLUS detects that the vehicle
in front

is stopping, it brakes your vehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake. After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
Depending on the specified minimum
distance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in 170

seat belt is unfastened.
R the engine is switched off, unless it is
automatically switched off by the ECO
start/stop function.
R a system malfunction occurs.
