Activating DISTRONIC PLUS; storing,
maintaining and calling up a speed Important safety notes
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations. To prevent dam-
age to the vehicle, deactivate DISTRONIC
PLUS and the HOLD function in the follow-
ing or other similar situations:
R when towing the vehicle
R in the car wash
To activate DISTRONIC PLUS, the following
conditions must be fulfilled:
R the engine must be running. It may take up
to two minutes of driving before DIS-
TRONIC PLUS is ready for use.
R your vehicle must not be secured by the
electric parking brake.
R ESP ®
must be activated.
R the transmission must be in position D.
R the bonnet must be closed. R
the driver's door must be closed when you
shift from Pto Dor your seat belt must be
fastened.
R the front-passenger door must be closed.
R the vehicle must not be skidding.
Activating Cruise control lever
X Briefly pull the cruise control lever towards
you ;, or press it up :or down =.
DISTRONIC PLUS is activated.
X Keep the cruise control lever pressed up :
or down =until the desired speed has
been 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.
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.
i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS inactive
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. You will be driving at the speed you deter-
mine by the position of the accelerator
pedal. Driving systems
187Driving and parking Z

Example: roundabout
The current speed is maintained:
R approximately ten seconds before the
roundabout/T-junction and for approx-
imately 1.5 second s when driving onthe
roundabout
R approximately twelve seconds before
reaching a motorway exit and approx-
imately four seconds after the motorway
exit
Afterwards, the vehicle accelerates back to
the set speed you specified.
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.
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.
Deactivate DISTRONIC PLUS (Y page 192).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 short period the vehicle is
secured by the electric parking brake, thus
relieving 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.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
and:
R the driver's door is open and the driver's
seat belt is unfastened
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function
R a system fault occurs
R the power supply is not sufficient
If a fault occurs, then the transmission may
also be shifted into position Pautomatically.
Storing the current speed and calling up
the last stored speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again. Driving systems

you change lanes or change your speed
ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentra-
tion until too late, or may not detect them at
all. The system is not a substitute for a well-
rested and attentive driver.
Warning and display messages in the
multifunction display X
Activate ATTENTION ASSIST using the on-
board computer (Y page 238).

do not take a break and ATTENTION ASSIST
still detects increasing lapses in concentra-
tion, you will be warned again after
15 minutes at the earliest. ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con-
tinue your journey if:
R you switch off the engine
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break

with camera
:attached at the top of the
windscreen.
i Speed Limit Assist is not operational in all
countries.
Speed Limit Assist shows you detected speed
limits in the multifunction display. Data from
the navigation system is also used for this
purpose. The display appears if Speed Limit
Assist detects a traffic sign indicating a speed
limit or the end of a speed limit. If Speed Limit Assist does not detect any traffic signs, the
speed limit from the digital road map is taken
and shown in the display.
Important safety notes Speed Limit Assist is only an aid and does not
always detect traffic signs specifying the
maximum permissible speed. Traffic signs Driving systems
