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

and right), only focusing on the vehicle in front if
detected lane markings are not present.
If these conditions are not present, Steering
Assist and Stop&Go Pilot cannot provide assis-
tance.
DISTRONIC PLUS must be active in order for the
function to be available.
Important safety notes If you fail to adapt your driving style, DISTRONIC PLUS with Steering Assist and Stop&Go Pilot
can neither reduce the risk of an accident nor
override the laws of physics. It cannot take into
account road, weather or traffic conditions.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot is only an aid. You are responsible
for the distance to the vehicle in front, for vehi- cle speed, for braking in good time and for stay-
ing in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions and does not detect all road users. If you are following a vehicle which is driving
towards the edge of the carriageway, your vehi-cle could come into contact with the kerb or
other road boundaries. Be particularly aware of
other road users, e.g. cyclists, that are directly
next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicle back to the lane. In such cases, you must steer
the vehicle yourself to ensure that it does not
leave the lane.
The support offered by the system may be
impaired if:
R there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,fog or spray
R there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera R
no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is narrow and winding
R there are highly variable shade conditions on
the road
The system is switched to passive and no longer assists you by performing steering interventions
if:
R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel or
do not steer for a prolonged period of time
i After you have finished changing lanes,
Steering Assist and Stop&Go Pilot are auto-
matically active again.
Steering Assist and Stop&Go Pilot cannot pro-
vide assistance:
R on very sharp corners
R when towing a trailer
R a loss of tyre pressure or a defective tyre has
been detected and displayed
Pay attention also to the important safety notes
for DISTRONIC PLUS (Y page 207).
The steering interventions are carried out with a limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Steering Assist
and Stop&Go Pilot switch to passive mode.

road Engineering package)
Important safety notes Level control adapts the vehicle level automati-
cally to the current operating and driving situa-
tion. This results in reduced fuel consumption
and improved handling.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle to adjust to the new level as quickly as possible.
The vehicle level may change visibly if you park
the vehicle and the outside temperature changes. If the temperature drops, the vehicle
level lowers; with an increase in temperature,
the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi-
cant level changes, e.g. after the vehicle has
been stationary for a long period, the engine
must be running. For safety reasons, the vehicle
is only lowered when the doors are closed. Low-
ering is interrupted if a door is opened; it con-
tinues once the door has been closed.

WARNING
People's limbs may become trapped if they
are located underneath the vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is a danger of
injury.
When lowering the vehicle, make sure no one
is underneath the vehicle or in the immediate vicinity of the wheel arches. G
WARNING
When driving at a raised vehicle level, the driv- ing characteristics may be significantly affec-ted by the vehicle's raised centre of gravity.
The vehicle may be more liable to tip when
cornering, for example. There is a risk of an
accident.
Always select as low a vehicle level as possi-
ble and adjust your driving style accordingly. G
WARNING
When driving with a lowered or raised chassis frame, the driving and braking characteristics
may be seriously affected. A raised chassis
frame may also exceed the permissible vehi-
cle height. There is a risk of an accident.
Set the driving level before pulling away. G
WARNING

Points to remember
General notes Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRIDmode, the hybrid
drive system automatically selects the most effi-
cient operating mode for every driving situation. Drive the vehicle in the usual manner.
To save fuel in HYBRIDmode, the hybrid drive
system switches off the combustion engine as
often as possible during the journey when power
output requirements are low. When power out-
put requirements are low, the electric motor
powers the vehicle. When power output require- ments are high, the combustion engine is
switched on, even during a journey. When the
vehicle is stationary, the combustion engine is
usually switched off. Consequently, there is usu-
ally no engine idling as with combustion engine
vehicles.
For pulling away and accelerating, the electric
motor supports the internal combustion engine using the power stored in the high-voltage bat-
tery. In addition, the power is used for electric
driving, operation of the electric refrigerant compressor and to supply the 12 V on-board
electrical system. In this way the hybrid drive
system helps to reduce your vehicle's fuel con-
sumption.
Observe the driving tips on plug-in hybrid oper-
ation (Y
page 268).
Recuperative Brake System If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is ini- tiated. The electric motor is operated as a alter-
nator when in overrun mode and when you
brake. Hybrid technology converts the kinetic
energy of the vehicle into electricity and stores
it in the high-voltage battery.
Observe the important safety notes for the
Recuperative Brake System (Y page 43). Important safety notes
If the engine is switched off by the ECO start/
stop function, you open the driver's door and
unfasten your seat belt: R a message appears in the multifunction dis-
play and
R a warning tone sounds
For further information, see (Y page 320).
All of the vehicle's systems remain active, if:
R the vehicle is stationary
R the combustion engine is switched off
R the READY-indicator in the instrument cluster
is lit
If you remove your foot from the brake pedal
while in transmission position D or R, the vehicle
could pull away automatically.
Observe the notes on the READY display of the
ECO start/stop function (Y page 269).
Vehicles with an electric motor generate signif-
icantly less noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain situations. This is the case, for example, when
you are parking and your vehicle is not seen by
other road users.
This requires you to adopt a particularly antici-
patory driving style, as it is necessary to allow
for the possibility that other road users may
behave unpredictably. Plug-in hybrid operation
