WARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or
brake unexpectedly. There is a risk of an acci-
dent.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.

X
PLUS: remove your foot from the brake pedal.

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-
mes-
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.
Selects the drive program
DISTRONIC PLUS supports a sporty driving style
when you have selected the S or S+ driving pro-
gram ( page 139). 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

accelerated. Acceleration will be interrupted if
