ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate
or brake unexpectedly. There is a risk of an
accident.
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.

Briefly pull the cruise control lever towards

Remove your foot from the accelerator

The first time Active Distance Assist
DISTRONIC is activated, it stores the current
speed or regulates the speed of the vehicle
to the previously stored speed.
Pulling away and driving
X
If you want to pull away with Active Dis-
tance Assist DISTRONIC: remove your foot
from the brake pedal.
X
Briefly pull the cruise control lever towards
you ?.
or

If Active Distance Assist DISTRONIC is acti-
vated: accelerate briefly.
Your 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 set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a dif-
ferent line from another vehicle. The vehicle
then brakes automatically. Be ready to brake
at all times.
If there is no vehicle in front, Active Distance
Assist DISTRONIC operates in the same way
as cruise control.
If Active Distance Assist DISTRONIC detects a
slower-moving vehicle in front, it brakes your
vehicle. In this way, the distance you have
selected is maintained.
If Active Distance Assist DISTRONIC 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
All vehicles (except AMG vehicles): Active
Distance Assist DISTRONIC supports a sporty
driving style when you have selected the S or
S+ drive program (Y page 132). Acceleration
behind the vehicle in front or to the set speed
is then noticeably more dynamic. If you have
selected the C or E driving program, the vehi-
cle accelerates more gently. This setting is
recommended in stop-and-start traffic.
AMG vehicles: Active Distance Assist
DISTRONIC supports a sporty driving style
when you have selected the S or S+ or M drive
program (Y page 133). Acceleration behind
the vehicle in front or to the set speed is then
noticeably more dynamic. When you select the
C drive program, the vehicle accelerates more
gently. This setting is recommended in stop-
and-start traffic.
Changing lanes
If you want to change to the overtaking lane
on multi-lane roads, Active Distance Assist
DISTRONIC supports you if:
R
you are driving faster than 45 mph
(70 km/h)
R
Active Distance Assist DISTRONIC is main-
taining the distance to a vehicle in front
R
you switch on the appropriate turn signal
R
Active Distance Assist DISTRONIC does not
currently detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
i
When you change lanes, Active Distance
Assist DISTRONIC monitors the left lane on
left-hand-drive vehicles or the right lane on
right-hand-drive vehicles.
Stopping
If Active Distance Assist 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 time, the electric parking brake
secures the vehicle and relieves the service
brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
