Pulling away and driving
XIf you want to pull away with Distance
Pilot DISTRONIC:remove your foot from the
brake pedal.
XBriefly pull the cruise control lever towards
you ?.
or
XIf Distance Pilot DISTRONIC is activated:
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.
iDistance 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 (
Ypage 136) or the manual drive program
(Ypage 138). 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:
Ryou are driving faster than 45 mph (70 km/h)
RDistance Pilot DISTRONIC is maintaining the
distance to a vehicle in front
Ryou switch on the appropriate turn signal
RDistance 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.
iAfter a time, the electric parking brake
secures the vehicle and relieves the service
brake.
iDepending 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 jif:
Rthe driver's seat belt is not fastened and the
driver's door is open.
Rthe 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:
Ra system malfunction occurs.
Rthe power supply is insufficient.
If a malfunction occurs, the transmission may
also shift to position jautomatically.
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.
XPress the cruise control lever up :for a
higher speed or down ;for a lower speed.
XTo adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly press
Driving systems159
Driving and parking
Z

the cruise control lever up:or down ;to
the pressure point.
The last stored speed increases or decreases
in 1 mph (1 km/h) increments.
XTo adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly press
the cruise control lever up :or down ;
beyond the pressure point.
The last stored speed increases or decreases in 5 mph (10 km/h) increments.
iDistance 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 (
Ypage 168).
The specified minimum distance can be
changed while Distance Pilot DISTRONIC is
switched on or off.
iMake sure that you maintain the minimum
distance to the vehicle in front as required by
law. Adjust the distance to the vehicle in front
if necessary.
XTo increase: turn control=in direction ;.
Distance Pilot DISTRONIC then maintains a
greater distance between your vehicle and
the vehicle in front.
XTo decrease: turn control=in direction :.
Distance Pilot DISTRONIC then maintains a
shorter distance between your vehicle and
the vehicle in front.
Deactivating Distance Pilot DISTRONIC
There are several ways to deactivate Distance
Pilot DISTRONIC:
XBriefly press the cruise control lever for-
wards :.
or
XBrake, unless the vehicle is stationary
XBriefly press the cruise control lever for-
wards :.
or
XBrake, unless the vehicle is stationary
When you deactivate Distance Pilot DISTRONIC,
the Distance Pilot Off
message appears in
the multifunction display for approximately five
seconds.
iThe last speed stored remains stored until
you switch off the engine. Distance Pilot
DISTRONIC is not deactivated if you depress
the accelerator pedal.
Distance Pilot DISTRONIC is automatically deac-
tivated if:
Ryou engage the electric parking brake or if the
vehicle is automatically secured with the elec- tric parking brake

Tips for driving with Distance Pilot
DISTRONIC
General notes
Pay particular attention in the following traffic
situations:
RCornering, entering and exiting a bend: the
ability of Distance Pilot DISTRONIC to detect
vehicles during cornering is limited. Your vehi-
cle may brake unexpectedly or late.
RDriving on a different line: Distance Pilot
DISTRONIC may not detect vehicles which are
not driving in the middle of their lane. The dis-
tance to the vehicle in front will be too short.
ROther vehicles changing lanes: Distance Pilot
DISTRONIC has not detected the vehicle cut-
ting in yet. The distance to this vehicle will be
too short.
RNarrow vehicles: Distance Pilot DISTRONIC
has not yet detected the vehicle in front on
the edge of the road because of its narrow
width. The distance to the vehicle in front willbe too short.
RObstacles and stationary vehicles: Distance
Pilot DISTRONIC does not brake for obstacles
or stationary vehicles. If, for example, the
detected vehicle turns a corner and an obsta-cle or stationary vehicle is then revealed, Dis-
tance Pilot DISTRONIC will not brake for
them.
RDistance Pilot DISTRONIC may mistakenly
detect vehicles that are crossing your lane. If
you activate Distance Pilot DISTRO
NIC in the
following situations, the vehicle could pull
away unintentionally:
-At traffic lights with crossing traffic, for
example.
-With a vehicle ahead on the other side of an
intersection and the HOLD function active.
In such situations, brake if necessary. Distance
Pilot DISTRONIC will then be deactivated.
HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic The vehicle is kept stationary without the driver
having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
Important safety notes
GWARNING
If the vehicle is only braked using the HOLD
function, the vehicle may roll away in the fol-
lowing situations when you leave the vehicle:
Rif there is a malfunction in the system or in the voltage supply
Rif the HOLD function is deactivated by
depressing the accelerator pedal or brake
pedal, e.g. by a vehicle occupant
Rif the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with or the battery is disconnected
There is a risk of an accident.
Always deactivate the HOLD function and
secure the vehicle against rolling away before
you leave it.
!When Distance Pilot DISTRONIC or the
HOLD function is activated, the vehicle
brakes automatically in certain situations.
To avoid damage to the vehicle, deactivate
Distance Pilot DISTRONIC and the HOLD
function in the following or similar situations:
Rwhen towing the vehicle
