tance between your vehicl
eand the vehicle in
front becomes too small.
i Whe nchanging lanes, DISTRONIC PLUS
monitors the left lane for left-hand-drive
vehicles and the right lane for right-hand-
drive vehicles.
Stopping G
WARNING
Never get out of the vehicle when DISTRONIC
PLUS is activated.
DISTRONIC PLUS must also never be oper-
ated, activated or deactivated by a passenger
or from outside the vehicle.
DISTRONIC PLUS does not replace the elec-
tric parking brake and must not be used for
parking.
The DISTRONIC PLUS braking effect is can-
celled and the vehicle can start moving if:
R DISTRONIC PLUS is deactivated using the
cruise control lever.
R you accelerate.
R there is a malfunction in the system or an
interruption in the power supply, e.g. bat-
tery failure.
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
R the battery is disconnected.
If you wish to leave the vehicle or park it,
deactivate DISTRONIC PLUS and secure the
vehicle against rolling away.
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 After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
i Depending on the specified minimum dis-
tance, 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.
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
be shifted into position Pautomatically.
Storing the current speed or calling up the
last stored speed G
WARNING
Only call up a stored speed if you know what
that speed is and if it is suitable for the current
traffic and driving situation. You can other-
wise endanger yourself or others by uninten-
tionally triggering sudden acceleration or
braking.
X Briefly pull the cruise control lever
(Y page 155) towards you.
X Remove your foot from the accelerator
pedal.
DISTRONIC PLUS is activated. The first
time it is activated, the current speed is
stored. Otherwise, it sets the vehicle cruise
speed to the previously stored value. 158
Driving systemsDriving and parking

Crossing vehicles
DISTRONIC PLUS may detect vehicles that
are crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with cross-
ing traffic, for example, could cause your vehi-
cle to pull away unintentionally. HOLD function

tthe driver in the
following situations:
R when pulling away, especially on steep
slopes

Never get out of the vehicle when the HOLD
function is activated. The HOLD function must never be operated
or deactivated by a passenger or from outside

tric parking brake and must not be used for
parking.
The braking effect of the HOLD function is
cancelled and the vehicle could roll away if:
R the HOLD function is deactivated by
depressing the accelerator pedal or the
brake pedal.
R there is a malfunction in the system or an
interruption in the power supply, e.g. bat-
tery failure.
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
