WARNING
DISTRONIC PLUS brakes your vehicle with up to 50% of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with a visual and
acoustic warning. There is a risk of an acci-
dent.
Apply the brakes yourself in these situations
and try to take evasive action.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
If you fail to adapt your driving style, DISTRONIC PLUS can neither reduce the risk of an accident
nor override the laws of physics. DISTRONIC
PLUS cannot take road and weather conditions
or traffic conditions into account. DISTRONIC
PLUS is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in lane.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line.
In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections, for
example, in multi-storey car parks
If DISTRONIC PLUS no longer detects a vehicle
in front, it may unexpectedly accelerate to the
speed stored. This speed can:
R be too high for a filter lane or a slip road
R be so high in the right lane that you pass vehi-
cles driving on the left
R be so high in the left lane that you pass vehi-
cles driving on the right
If there is a change of drivers, advise the new
driver of the speed stored.

Activating
X Briefly pull the cruise control lever towards
you ?, up :or down A.
DISTRONIC PLUS is activated.
X Remove your foot from the accelerator pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS inactive
DISTRONIC PLUS inactive mes-
sage appears in the multifunction display. The
set distance to a slower-moving vehicle in
front will then not be maintained. The position of the accelerator pedal will determine the
speed.
You can also activate DISTRONIC PLUS when
stationary. The lowest speed that can be set is
30 km/h.
X Briefly pull the cruise control lever towards
you ?, up :or down A.
DISTRONIC PLUS is activated. Activating at the current speed/last
stored speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X Briefly pull the cruise control lever towards
you ?.
X Remove your foot from the accelerator pedal.
DISTRONIC PLUS is on and, when activated
for the first time, accepts the current speed or
it adjusts the vehicle's speed to the speed
stored.
Driving with DISTRONIC PLUS Pulling away and driving
X If you want to pull away with DISTRONIC
PLUS: remove your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or 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.
If there is no vehicle in front, DISTRONIC PLUS
operates in the same way as cruise control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes your vehicle. In
this way, the distance you have selected is main- tained.
If DISTRONIC PLUS 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. Driving systems
209Driving and parking Z

Selecting the drive program
DISTRONIC PLUS supports a sporty driving style
if you have selected the SportorSport Plus
drive program (Y page 171). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have
selected the Comfortdrive program, the vehicle
accelerates more gently. This setting is recom-
mended in stop-start traffic.
Changing lanes If you change to the overtaking lane, DISTRONIC
PLUS supports you if:
R you are driving faster than 70 km/h
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect a danger of
collision
If these conditions are met, your vehicle is accel- erated. Acceleration will be interrupted if chang-
ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
i Vehicles with COMAND Online:
when you
change lanes, DISTRONIC PLUS monitors the right lane in the case of left-side traffic or the
left lane in the case of right-side traffic.
Vehicles with Audio 20: when you change
lanes, DISTRONIC PLUS monitors the left lane on left-hand-drive vehicles or the right lane onright-hand-drive vehicles.
Vehicles with COMAND Online i
The following function is only available in
vehicles with the Driving Assistance Plus
package.
The function is not operational in all coun-
tries. DISTRONIC PLUS uses additional information
from your navigation system so that it can adapt
to certain traffic situations. This is the case if,
while following a vehicle, DISTRONIC PLUS is
active and you:
R approach or drive around a roundabout
R approach a T-junction
R turn off at a motorway exit
R approach a tollgate
Even if the vehicle in front leaves the detection
range, DISTRONIC PLUS temporarily maintains
the current driving speed and does not acceler- ate. This is based on the current map data in the
navigation system.
Afterwards, the vehicle accelerates back to the
set speed you specified.
The system takes into account the fact that
overtaking on the right is not permitted on
motorways or high-speed major roads at speeds
above 80 km/h. The driving speed is adjusted to the speed of the queue of vehicles in the adja-
cent lane to the left.
i Prevention of overtaking on the right applies
to countries where traffic drives on the right.
In countries where traffic drives on the left,
overtaking on the left is prevented accord-
ingly.
Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi- cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away. 210
Driving systemsDriving and parking

If DISTRONIC PLUS 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 short period, the vehicle is secured by
the electric parking brake, thus relieving the
service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever.
When the vehicle is stationary and DISTRONIC
PLUS is activated, position P is automatically
selected if:
R the driver's door is open and the driver's seat
belt is unfastened
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 DISTRONIC PLUS is activated
when the vehicle is stationary and:
R a system fault occurs
R the power supply is insufficient
On steep uphill or downhill inclines or if there is
a malfunction, the transmission may also be
automatically shifted into position P.
Setting a speed Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.
X Press the cruise control lever up :for a
higher speed or down Afor a lower speed
X Keep the cruise control lever pressed until the
desired speed is reached.
X Release the cruise control lever.
The new speed is stored. DISTRONIC PLUS is
activated and adjusts the vehicle's speed to
the new speed stored. X
To adjust the set speed in 1 km/h incre-
ments:
briefly press the cruise control lever
up : or down Ato the pressure point.
The last stored speed increases or decreases in 1 km/h increments.
X To adjust the set speed in 10 km/h incre-
ments: briefly press the cruise control lever
up : or down Abeyond the pressure point.
The last stored speed increases or decreases
in 10 km/h increments.
i If you accelerate to overtake, DISTRONIC
PLUS adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Setting the specified minimum distance You can set the specified minimum distance for
DISTRONIC PLUS by varying the time span
between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS maintains to the vehicle in
front, dependent on vehicle speed. You can see this distance in the multifunction display
(Y page 213).
X To increase: turn control;in direction =.
DISTRONIC PLUS then maintains a greater
distance between your vehicle and the vehicle
in front.
X To decrease: turn control;in direction :.
DISTRONIC PLUS then maintains a shorter
distance between your vehicle and the vehicle in front.
i Make sure that you maintain a sufficient and
safe distance from the vehicle in front. Adjust the distance to the vehicle in front if neces-
sary. Driving systems

Important safety notes
G
WARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. This
increases the risk of skidding and having an
accident.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor override the laws of physics. DSR cannot take account ofroad, weather and traffic conditions. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not
always be able to keep to the set speed, depend-
ing on road surface and tyre conditions. Select a set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.
Activating DSR X
Press button :.
Indicator lamp ;lights up.
The à DSR symbol appears in the multi-
function display.
You can only activate DSR when driving at
speeds below 40 km/h.
If the current vehicle speed is too high, the Ã
DSR symbol appears in the multifunction display
with the Max. speed 40 km/h
Max. speed 40 km/h message.
If you have activated DSR and then change drive programs, DSR is deactivated. If you switch between the offroad and offroad plus drive pro-
grams, DSR remains activated.
Deactivating DSR
X Press button :.
Indicator lamp ;goes out.
The à DSR symbol appears in the multi-
function display with the off offmessage.
DSR switches off automatically if you drive
faster than 45 km/h. The ÃDSR symbol
appears in the multifunction display with the
off off message. The status indicator in the multi-
function display goes out. You also hear a warn-
ing tone.
On vehicles with the Offroad Engineering pack-
age, if you select a different drive program, DSR is also deactivated. If you switch between the
offroad programs, DSR remains activated.
Changing the set speed X
To increase or reduce the set speed in
1 km/h increments:
briefly press the cruise
control lever up :for a higher set speed or
down ;for a lower set speed.
The set speed appears in the multifunction
display with the ÃDSR symbol.
When DSR is activated, you can change the set
speed to a value between 2 km/h and 18 km/h.
i The DSR set speed is always changed in
1 km/h increments. This is regardless of
whether you press the cruise control lever to or beyond the pressure point. Driving systems
253Driving and parking Z

When towing a trailer, your vehicle's handling
characteristics will be different in comparison to
when driving without a trailer and it will con-
sume more fuel.
Use the left-hand gearshift paddle to shift to a
lower gear on long and steep downhill gradients.
This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
This will use the braking effect of the engine, so
less braking will be required to maintain vehicle
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
Driving tips If the trailer swings from side to side:
X Do not accelerate.
X Do not countersteer.
X Brake if necessary.
R Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility, decrease with increasing altitude. Swinging out the ball coupling
G
WARNING
If the ball coupling is not engaged, the trailer
may come loose. There is a risk of an accident.
Make sure that the ball coupling is securely
engaged and locked in position.
! Do not attempt to speed the up the swing-
out procedure by applying additional pressure
with your foot. The system could otherwise be
mechanically damaged. To fold out the ball coupling, you have two
options:
R use the switch in the driver's door (all vehicles
except PLUG-IN HYBRID vehicles)
R use the switch in the tailgate
The trailer power socket is integrated into the
ball coupling and swivels out with it.
Only release the ball coupling when its range of movement is unobstructed. Folding out using the switch in the driver's
door (all vehicles except plug-in hybrid vehi-
cles):
X Make sure that the vehicle is stationary.
X Shift the transmission to position P.
X Switch the ignition on.
X Pull switch :briefly.
After a short time the ball coupling swings out from under the rear bumper. It can take up to
seven seconds before the ball coupling visibly
swings out.
X Remove the protective covering from the ball
coupling and store it in a safe place.
