WARNING
If you call up the stored speed and it differs
from the current speed, the vehicle
accelerates or decelerates. If you do not know
the stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an
accident.
Pay attention to the road and traffic
conditions before calling up the stored speed.
If you do not know the stored speed, store the
desired speed again. X
Briefly pull the cruise control lever towards

X
If you want to pull away with
DISTRONIC PLUS: remove your foot from
the brake pedal.
X Briefly pull the cruise control leve rtowards
you 0002.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If no vehicle is detected in front, your
vehicle accelerates to the set speed.
i The vehicle can also pull away when it is
facing an unidentified obstacle or is driving
on a different line from another vehicle. The
vehicle then brakes automatically. There is
a risk of an accident. Be ready to brake at
all times.
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. In this way, the distance you have
selected is maintained.
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.
Selecting the drive program
DISTRONIC Plus supports a sporty driving
style when you have selected the Sdriving
program (Y page 175). Acceleration behind
the vehicle in front or to the set speed is then
noticeably more dynamic. If you have
selected the Edriving program, the vehicle
accelerates more gently. This setting is
recommended in stop-and-start traffic. Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
R you are driving faster than 45 mph
(70 km/h)
R DISTRONIC PLUS is maintaining the
distance to a vehicle in front
R you switch on the appropriate 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.
i When changing lanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles.
Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a
vehicle occupant or from outside the
vehicle.
R the electrical system in the engine
compartment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.

in front is stopping, it brakes yourv ehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
Depending on the specified minimum
distance, your vehicle will come to a standstill
at a sufficien tdistance behind the vehicle in
front .The specified minimum distance is set
using the control on the cruise control lever.
When DISTRONIC PLUS is activated, the
transmission is shifted automatically to
position Pif:
R the driver's door is open and the driver's
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.
R the power supply is not sufficient.

i If you accelerate to overtake, DISTRONIC
PLUS adjusts the vehicle's speed to the last
speed stored after you have finished
overtaking.
Setting the specified minimum distance You can set the specified minimum distance
for DISTRONIC PLUS by varying the time span
between one and two seconds. With this
function, you can set the minimum distance
that DISTRONIC PLUS keeps to the vehicle in
