Pulling away and driving
If you want to pull away with Distance
X
Pilot DISTRONIC: remove your foot from the
brake pedal.
Briefly pull the cruise control lever towards
X
you ?.
or
If Distance Pilot DISTRONIC is activated:
X
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 differ-
ent line from another vehicle. The vehicle then
brakes automatically. Be ready to brake at all
times.
If there is no vehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise
control.
If Distance Pilot DISTRONIC detects a slower-
moving vehicle in front, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If Distance Pilot 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.
i
Distance Pilot DISTRONIC is deactivated
when you depress the brake, except when the
vehicle is stationary.
Selecting the drive program
Distance Pilot DISTRONIC supports a sporty
driving style when you select the S+ drive pro-
gram ( page 136) or the manual drive program
Y
( page 138). Acceleration behind the vehicle in
Y
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 recom-
mended in stop-and-start traffic.
Changing lanes
If when driving on multilane roads you wish to
change to the overtaking lane, Distance Pilot
DISTRONIC supports you if:
you are driving faster than 45 mph (70 km/h)
R
Distance Pilot DISTRONIC is maintaining the
R
distance to a vehicle in front
Driving systems
you switch on the appropriate turn signal
R
Distance Pilot DISTRONIC does not currently
R
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 distance
between your vehicle and the vehicle in front
becomes too small.
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.
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 Distance Pilot DISTRONIC is activated,
the transmission is shifted automatically to
position j 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 Distance Pilot DISTRONIC is
activated when the vehicle is stationary and:
a system malfunction occurs.
R
the power supply is insufficient.
R
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.
Press the cruise control lever up : for a
X
higher speed or down ; for a lower speed.
To adjust the set speed in 1 mph incre-
X
ments (1 km/h increments): briefly press
