Selecting the drive program
Active Distance Assist DISTRONIC supports a
sporty driving style when you select the S+
drive program (
Y
page 138) or the manual
drive program (
Y
page 140). Acceleration
behind the vehicle in front or to the set speed
is then noticeably more dynamic. If you have
selected the E (Mercedes-AMG vehicles: 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.
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.
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 Active Distance Assist DISTRONIC is
activated, the transmission is shifted automati-
cally to position
j
if:
R
the driver's seat belt is not fastened and the
driver's door is open.
R
the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function.
The electric parking brake is applied automati-
cally if Active Distance Assist DISTRONIC is
active when the vehicle is stationary and:
R
a system malfunction occurs.
R
the power supply is insufficient.
If a malfunction occurs, the transmission may
also shift to position
j
automatically.
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.
X
Press the cruise control lever up
:
for a
higher speed or down
;
for a lower speed.
X
To adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly push
the cruise control lever up
:
or down
;
to
the pressure point.
The last stored speed increases or decrea-
ses in 1 mph (1 km/h) increments.
X
To adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly push
the cruise control lever up
:
or down
;
beyond the pressure point.
The last stored speed increases or decrea-
ses in 5 mph (10 km/h) increments.
i
Active Distance Assist DISTRONIC is not
deactivated if you depress the accelerator
pedal. If you accelerate to overtake, Active
Distance Assist DISTRONIC adjusts the vehi-
cle's speed to the last speed stored, after
you have finished overtaking.
Setting a specified minimum distance
You can set the specified minimum distance
for Active Distance Assist DISTRONIC by vary-
ing the time span between one and two sec-
onds. This determines the distance that Active
Distance Assist DISTRONIC is to maintain from
the vehicle in front, depending on the road
speed. You can see this distance in the multi-
function display (
Y
page 164).
