The following function is not operational in
all countries.
Distance Pilot DISTRONIC uses additional infor-
mation from your navigation system so that it
can adapt to certain traffic situations. This is the
case if, while following a vehicle, Distance Pilot
DISTRONIC is active and you:
approach or drive around a roundabout
R
approach a T-junction
R
turn off at a motorway exit
R
Even if the vehicle in front leaves the detection
range, Distance Pilot DISTRONIC temporarily
maintains the current driving speed and does
not accelerate. This is based on the current map
data in the navigation system.
Afterwards, the vehicle accelerates back to the
speed you set.
The system takes into account the fact that
overtaking on the right is not permitted on
motorways or high-speed major roads at speeds
above 80 km/h. The driving speed is adjusted to
the speed of the queue of vehicles in the adja-
cent lane to the left.
i
Prevention of overtaking on the right applies
to countries where traffic drives on the right.
In countries where traffic drives on the left,
overtaking on the left is prevented accord-
ingly.
Stopping
If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary 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 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.
The electric parking brake secures the vehicle
automatically if Distance Pilot DISTRONIC is
activated and:
the driver's door is open and the driver's seat
R
belt is unfastened
the engine is switched off, unless it is auto-
R
matically switched off by the ECO start/stop
function
a system fault occurs
R
the power supply is insufficient
R
If a malfunction in the electric parking brake
occurs, then the transmission may also be shif-
ted into position P automatically.
Setting a speed
Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.
Press the cruise control lever up : for a
X
higher speed or down A for a lower speed.
Keep the cruise control lever pressed until the
X
desired speed is reached or press the cruise
control lever repeatedly until the desired
speed is reached.
Release the cruise control lever.
X
The new speed is stored. Distance Pilot
DISTRONIC is activated and adjusts the vehi-
cle's speed to the new speed stored.
To adjust the set speed in 1 km/h incre-
X
ments: briefly press the cruise control lever
up : to the pressure point for a higher speed
or down A for a lower speed.
The last speed stored is increased or reduced.
To adjust the set speed in 10 km/h incre-
X
ments: briefly press the cruise control lever
up : beyond the pressure point for a higher
speed, or down A for a lower speed.
The last speed stored is increased or reduced.
Setting the specified minimum distance
You can set the specified minimum distance for
Distance Pilot DISTRONIC by varying the time
span between one and two seconds. With this
function you can set the minimum distance that
Distance Pilot DISTRONIC maintains to the vehi-
cle in front, dependent on vehicle speed. You
can see this distance in the multifunction dis-
play (
page 166).
Y
The specified minimum distance can be
changed when Distance Pilot DISTRONIC is acti-
vated or deactivated.
Make sure that you maintain a sufficient and
safe distance from the vehicle in front. Adjust
the distance to the vehicle in front if necessary.
