Risk of accident
The vehicle can be braked when DISTRONIC
PLUS is activated. For this reason, deactivate
DISTRONIC PLUS if the vehicle is to be set in
motion by other means (e.g. in acar wash or
by towing).
You can activate Distronic Plus in the follow-
ing circumstances:
R after the engine has been running for about
two minutes
R if the parking brake is not applied
R if ESP ®
is activated
R if the automatic transmission* is in position
D
R if the bonnet is closed
R if the driver's door is closed and you switch
from Pto Dor your seat belt is fastened.
R if the front-passenger door is closed
Activating while driving
When driving at speeds below 30 km/h, you
can only activate Distronic Plus if the vehicle
in front has been detected and is shown in the
multi-function display.Ift he vehicle in front is
not shown in the multi-function display and is
no longer being detected, because it has
changed lanes, for example, Distronic Plus is
deactivated and atone sounds. X
Briefly pull the cruise control lever towards
you 0088or press it up 0046or down 0086to the
pressure point.
Distronic Plus is selected.
X Keep the cruise control lever pressed
up 0046 or down 0086until 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,b ut only up to the stored
speed.
i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS suspended
message appears in the multi-function dis-
play.T he set distance to aslower-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.
Activating when driving towards asta-
tionary 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 0088.
Distronic Plus is selected.
i Distronic Plus can only be activated at
under 30 km/hi favehicle in front has been
detected. Therefore, the Distronic Plu sdis-
tance displayint he instrument cluster

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 0088.
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,D istronic Plus
operates in the same way as cruise control.
If as lower-moving vehicle is detected in front,
Distronic Plus causes your vehicle to brake
and maintain apreset distance to the vehicle
in front.
If Distronic Plus detectsaf aster-moving vehi-
cle in front,iti ncreases the driving speed, but
only up to the stored speed. G
Risk of accident
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
DISTRONIC PLUS then no longer brakes your
vehicle. The driver is fully responsible for the
vehicle's distance from other vehicles, its
speed and for braking in good time.
Stopping G
Risk of accident
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 the system or the power supply is disrup-
ted, e.g. due to battery failure.
R the electrical system in the engine com-
partment or the fuses are tampered with.
R the battery is disconnected. G
Risk of accident
Never get out of the vehicle when DISTRONIC
PLUS is activated.
DISTRONIC PLUS must never be operated or
deactivated by apassenger or from outside
the vehicle.
DISTRONIC PLUS does not replace the park-
ing brake and must not be used for parking.
If you wish to leave the vehicle or park it,
deactivate DISTRONIC PLUS and secure the
vehicle against rolling away.
If Distronic Plus detectst hat 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 dis-
tance, your vehicle will come to astandstill
at as ufficient distance behind the vehicle
in front.T he specified minimum distance is
set using the thumbwheel on the cruise-
control lever.
When Distronic Plus is activated and the vehi-
cle is at astandstill, awarning message
appears in the multi-function display if:
R the driver's door is opened and you release
the seat belt.
R the engine is switched off.
R the bonnet is opened.
Select Park (P)
X Move the selector lever to Pto prevent the
vehicle from rolling away.
Distronic Plus is deactivated. The warning
message in the multi-function display dis-
appears.
Ah orn will also sound at regular intervals if
