Driving with DISTRONIC PLUS
Pulling away and driving
If you want to pull away with DISTRONIC
X
PLUS: remove your foot from the brake pedal.
Briefly pull the cruise control lever towards
X
you ?.
or
Accelerate briefly.
X
The 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 stored speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically.
If DISTRONIC PLUS does not detect a vehicle in
front, the system operates like a cruise control.
If DISTRONIC PLUS detects that the vehicle in
front is driving slower, your vehicle brakes. In
this way, the specified minimum distance you
have selected is maintained.
If DISTRONIC PLUS detects that the vehicle in
front is driving faster, your vehicle accelerates
to the stored speed.
Selecting the drive program
DISTRONIC PLUS supports a sporty driving style
when you have selected the S or S+ driving pro-
gram ( page 148). Acceleration behind the
Y
vehicle in front or to the set speed is then notice-
ably more dynamic. If you have selected the C or
E driving program, the vehicle accelerates more
gently. This setting is recommended in stop-
and-start traffic.
Changing lanes
DISTRONIC PLUS aids you when switching to
the overtaking lane, if:
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
R
a 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.
Driving systems
When you change lanes, DISTRONIC PLUS mon-
itors the left lane (on left-hand-drive vehicles) or
the right lane (on right-hand-drive vehicles).

WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
there is a malfunction in the system or in
R
the voltage supply.
DISTRONIC PLUS has been deactivated
R
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
the electrical system in the engine com-
R
partment, the battery or the fuses have
been tampered with.
the battery is disconnected.
R
the accelerator pedal has been depressed,
R
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 ( page 173).
Y
If DISTRONIC PLUS detects that the vehicle in
front has stopped, it will cause your vehicle to
brake and come to a halt.
Once your vehicle is stationary, it remains sta-
tionary 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 distance,
your vehicle will come to a standstill at a suffi-
cient distance 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 trans-
mission is shifted automatically to position P if:
the driver's seat belt is not fastened and the
R
driver's door is open.
the engine is switched off, unless it is auto-
R
matically switched off by the ECO start/stop
function.
