Driving with DISTRONIC PLUS
Pulling away and driving
X
If you want to pull away with
DISTRONIC PLUS: remove your foot from
the brake pedal.
X Briefly pull the cruise control lever towards
you 0043.
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.
The vehicle can also pull away when it is
facing an unidentified obstacle or is driving on
a different line from another vehicle. The vehi-
cle then brakes automatically. 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 tothe speed you have stored.
Selects the drive program
All vehicles (except AMG vehicles):
DISTRONIC PLUS supports a sporty driving
style when you select the Sdrive program (Y
page 158). Acceleration behind the vehicle
in front or to the set speed is then noticeably
more dynamic. If you have selected the E
driving program, the vehicle accelerates
more gently. This setting is recommended in
stop-and-start traffic.
AMG vehicles: DISTRONIC Plus supports a
sporty driving style when you select the Sor
M drive program (Y page 158). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. When you
select the Cdrive program, the vehicle accel-
erates more gently. This setting is recom-
mended 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 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 dis-
tance 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 vehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with. Driving syste

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.
For further information on deactivating
DISTRONIC PLUS (Y page 184).
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 dis-
tance, your vehicle will come to a standstill at a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.
When the HOLD function is activated, the
transmission is shifted automatically to posi-
tion Pif:
R the driver's seat belt is not fastened and the
driver's door is open.
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
R a system malfunction occurs.
R the power supply is not sufficient.
If a malfunction in the electric parking brake
occurs, then the transmission may also be
shifted into position Pautomatically. Setting a speed

stored is increased or reduced.
i If you accelerate to overtake, DISTRONIC
PLUS adjusts the vehicle's speed to the last
speed stored after you have finished over-
taking.
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 func-
tion, you can set the minimum distance that
DISTRONIC PLUS keeps to the vehicle in
front, dependent on vehicle speed. You can
see this distance in the multifunction display
(Y page 183).
