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 (Mercedes-AMG vehicles only), S
( Y
page 133) or the manual drive program
( Y
page 135). 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 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: R
you are driving faster than 45 mph (70 km/h) R
Distance Pilot DISTRONIC is maintaining the
distance to a vehicle in front R
you switch on the appropriate turn signal R
Distance Pilot 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 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 P 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 secures the vehicle
automatically if Distance Pilot DISTRONIC is
activated 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 into position P 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 C for a
higher speed or down D for a lower speed.X
To adjust the set speed in1 mphincre-
ments (1 km/hincrements): briefly press
the cruise control lever up C or down D to
the pressure point.
The last stored speed increases or decreases
in 1 mph (1 km/h) increments. X
To adjust the set speed in5 mphincre-
ments (10 km/hincrements): briefly press
the cruise control lever up C or down D to
the pressure point.
The last stored speed increases or decreases
in 5 mph (10 km/h) increments.
i Distance Pilot DISTRONIC is not deactivated
if you depress the accelerator pedal. If you
accelerate to overtake, Distance Pilot
DISTRONIC adjusts the vehicle's speed to the
last speed stored after you have finished over-
taking.
Setting a specified minimum distance
You can set the specified minimum distance for
Distance Pilot DISTRONIC by varying the time
span between one and two seconds. With this
function you can set the minimum distance that
Distance Pilot DISTRONIC maintains to the vehi-
cle in front, dependent on vehicle speed. You
can see this distance in the multifunction dis-
play ( Y
