Switching on DISTRONIC PLUS, storing
and maintaining the current speed Activation conditions
In order to activate DISTRONIC PLUS, the
following conditions must be fulfilled:
R
the engine must be started. It may take up
to two minutes after pulling away before
DISTRONIC PLUS is operational.
R the parking brake must be released.
R ESP ®
must be active, but not intervening.
R the transmission must be in position D.
R the hood 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 skid.
Activating while driving
You can only activate DISTRONIC PLUS when
driving at speeds below 20 mph (30k m/h) if
the vehicle in front has been detected and is
show ninthe multifunction display. If the Driving systems
161Driving and parking Z

vehicle in front is no longer detected and
displayed, DISTRONIC PLUS switches off and
a tone sounds.
X
Briefly pull the cruise control leve rtowards
you 0021, or press it up 0002or down 0003.
DISTRONIC PLUS is selected.
X Press the cruise control lever repeatedly
up 0002 or down 0003until 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.
i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS Override message 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.
Activating when driving towards a
stationary vehicle
If the vehicle in front of you is stationary, you
can only activate DISTRONIC PLUS once your
vehicle is stationary as well.
X Briefly pull the cruise control lever towards
you 0021, or press it up 0002or down 0003.
DISTRONIC PLUS is selected.
i DISTRONIC PLUS can only be activated at
under 20 mph (30 km/h) if avehicle in front
has been detected. Therefore, the
DISTRONIC PLUS distance display in the
instrument cluster should be activated
(Y page 198).
X Press the cruise control lever repeatedly
up 0002 or down 0003until the desired speed
is set.
i You can use the cruise control lever to set
the stored speed and the control on the
cruise control lever to set the specified
minimum distance (Y page 164). Pulling away
X
If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you 0021.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
Driving
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 fron thas slowed down, it brakes your
vehicle .Inthis way, the distance you have
selected is maintained.
If DISTRONIC PLUS detects that the vehicle
in front is driving faster, it accelerates your
vehicle, but only up to the speed you have
stored.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
R you are driving faster than 40 mph
(60 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. 162

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.
Deactivating DISTRONIC PLUS
(Y page 165).
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.
i Depending on the specified minimum
distance, your vehicle will come to a
standstill at a sufficient distance behind the
vehicle in front.T he specified minimum
distance is set using the control on the
cruise control lever.
You will see a warning message in the
multifunction display 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.
R the hood is opened.

DISTRONIC PLUS is activated and you:
R switch the engine off, open the driver's
door and remove your seat belt
R open the hood
The sounding of the horn alerts you to the fact
that the vehicle has been parked while
DISTRONIC PLUS is still activated. The sound
becomes louder if you attempt to lock the
vehicle. The vehicle is not locked until
DISTRONIC PLUS is deactivated.
i If the engine has been switched off, it
cannot be started again until DISTRONIC
PLUS has been deactivated.
If DISTRONIC PLUS is activated and a
malfunction occurs in the system or if there
is a disruption in the power supply, the
Brake Immediately message is shown in
the multifunction display. Depress the brake
firmly immediately until the warning message
disappears from the multifunction display or
shift the transmission to position P.
DISTRONIC PLUS is then deactivated.

speed to the previously stored value.
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
front, dependent on vehicle speed. You can
see this distance in the multifunction display
(Y
page 165).
i Make sure that you maintain a sufficient
distance to the vehicle in front and comply
with the minimum distance as required by
law. Adjust the distance to the vehicle in
front if necessary. X
To increase: turn control0003in direction
0022.
DISTRONIC PLUS then maintains a greater
distance between your vehicle and the
vehicle in front.
X To decrease: turn control0003in
direction 0002.
DISTRONIC PLUS then maintains a shorter
distance between your vehicle and the
vehicle in front.
DISTRONIC PLUS displays in the
speedometer When DISTRONIC PLUS is activated, one or
two segments
0003in the set speed range light
up.
i For design reasons, the speed displayed
in the speedometer may differ slightly from
