must be closed.
Arming X Briefly pull the cruise control lever towards
you ?, up :or down A.
DISTRONIC PLUS is selected.
X Keep the cruise control lever pressed up :
or down Auntil the desired speed is set.
X Remove your foot from the accelerator
pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
iIf you do not fully release the accelerator
pedal, the
DISTRONICPLUSPassivemes-
sage appears in the multifunction display.
The set distance to a slower-moving vehicle in front will then not be maintained. You will
be driving at the speed you determine by
the position of the accelerator pedal.
You can also activate DISTRONIC PLUS when
stationary. The lowest speed that can be set is
30 km/h.
Driving with DISTRONIC PLUS
Pulling away and driving
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 you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary. X
If you want to pull away with
DISTRONIC PLUS: remove your foot from
the brake pedal.
X Briefly pull the cruise control lever (Y page 164) towards you ?.
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 vehi-
cle accelerates to the set speed.
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. 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 Sor Mdriv-
ing program ( Ypage 147). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have
selected the E(AMG vehicles: C) drive pro-
gram, 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 70 km/h
R DISTRONIC PLUS is maintaining the dis-
tance 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 dis-
tance between your vehicle and the vehicle infront becomes too small.
Stopping
GWARNING
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.
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.
For further information on deactivating
DISTRONIC PLUS ( Ypage 167).
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.
iAfter a time, the electric parking brake
secures the vehicle and relieves the service
brake.
iDepending 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
:To store the current speed or a higher speed
;To store the current speed or a lowerspeed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to the speed set.
X Press the cruise control lever up :for a
higher speed or down ;for a lower speed.

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 168).
iMake sure that you maintain the mini-
mum distance to the vehicle in front as
required by law. Adjust the distance to the vehicle in front if necessary.
X To increase: turn control=in direc-
tion ;.
DISTRONIC PLUS then maintains a greater distance between your vehicle and the
vehicle in front.
X To decrease: turn control=in direc-
tion :.
DISTRONIC PLUS then maintains a shorter
distance between your vehicle and the
vehicle in front.
Deactivating DISTRONIC PLUS
There are several ways to deactivate
DISTRONIC PLUS:
X Briefly press the cruise control lever for-wards :.
or
X Brake, unless the vehicle is stationary
If you deactivate DISTRONIC PLUS, you will
see the
DISTRONICPLUSOffmessage in the
multifunction display for approximately five seconds.
iThe last speed stored remains stored until
you switch off the engine. DISTRONIC PLUS
is not deactivated if you depress the accel-
erator pedal.
DISTRONIC PLUS is automatically deactiva-

Tips for driving with DISTRONIC PLUS
General notes
The following contains descriptions of certain
road and traffic conditions in which you must be particularly attentive. In such situations,
brake if necessary. DISTRONIC PLUS is then
deactivated.
Cornering, going into and coming out of a
bend
The ability of DISTRONIC PLUS to detect vehi- cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles traveling on a different line
DISTRONIC PLUS may not detect vehicles
traveling on a different line. The distance to
the vehicle in front will be too short.
