Setting A Speed - Mercedes-Benz MY17 c-class Operator's Manual

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
front has slowed down, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program
DISTRONIC PLUS supports a sporty driving style
when you have selected the S or S+ driving pro-
gram ( page 144). 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
If you change to the passing lane, DISTRONIC
PLUS supports you when:
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
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 you change lanes, DISTRONIC PLUS
monitors the left lane on left-hand-drive vehi-
cles or the right lane on right-hand-drive vehi-
cles.

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 sta-
tionary 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. 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.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
a system malfunction occurs.
R
the power supply is not sufficient.

If a malfunction occurs, the transmission may
also shift into position P automatically.
