If a headlight flash is activated when
the high beam is on, the high beam
assist will be deactivated.
If a headlight flash is activated when
the high beam is off, the high beam
assist will remain activated.
High beam assist is always active
after the ignition is switched on.
Dynamic automatic headlight
levelling
To prevent oncoming traffic from dazzle, headlight levelling is
automatically adjusted based on
inclination information measured by
front and rear axle, acceleration or
deceleration and vehicle speed.
Fault in Adaptive forward
lighting system When the system detects a failure in
the Adaptive forward lighting system,
the system moves to a preset position to avoid dazzling of oncoming traffic.
Have the cause of the failure
remedied by a workshop as soon as
possible.Hazard warning flashers
Operated with the ¨ button.

If the lever is moved past the
resistance point, the turn signal is
switched on constantly. When the
steering wheel moves back, the turn
signal is automatically deactivated.
For three flashes, e.g. when changing
lanes, press the lever until resistance
is felt and then release.
Move the lever to the resistance point
and hold for longer indication.

Control of the vehicleNever coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 123.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.Steering
If power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.
Control indicator c 3 86.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 10 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.

122Driving and operatingStarting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
battery.

124Driving and operating
Deactivation
Deactivate the stop-start system
manually by pressing Ï.
Deactivation is indicated when the
LED in the button extinguishes.
Autostop
If the vehicle is at a low speed or at a standstill, activate an Autostop as
follows:
■ Depress the clutch pedal.
■ Set the lever in neutral.
■ Release the clutch pedal.
The engine will be switched off while
the ignition stays on.
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During an Autostop, the heating
performance, power steering and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled:
■ The stop-start system is not manually deactivated .
■ The bonnet is fully closed.
■ The driver's door is closed or the driver's seat belt is fastened.
■ The battery is sufficiently chargedand in good condition.
■ The engine is warmed up.
■ The engine coolant temperature is not too high.
■ The engine exhaust temperature is
not too high, e.g. after driving with
high engine load.
■ The ambient temperature is not too
low.
■ The climate control system allows an Autostop.
■ The brake vacuum is sufficient.
■ The self-cleaning function of the diesel particle filter is not active.
■ The vehicle has moved since the last Autostop.
Otherwise an Autostop will be
inhibited.
Ambient temperature near to the
freezing point can inhibit an Autostop.
Certain settings of the climate control
system may inhibit an Autostop. See
'Climate control' chapter for more
details.

126Driving and operatinguphill slope. Depress foot brake
at the same time to reduce
operating force.
■ Switch off the engine.
■ If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector lever to position P before removing
the ignition key. On an uphill
slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P before removing the ignition
key. Turn the front wheels
towards the kerb.
■ Close the windows and the sunroof.
■ Remove the ignition key. For vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.Turn the steering wheel until the
steering wheel lock is felt to
engage.
■ Lock the vehicle.
■ Activate the anti-theft alarm system.
Notice
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain
time.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may

144Driving and operatingadvanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.
Do not reverse the vehicle by only looking at the Info-Display and
check the surrounding area
behind and around the vehicle
before reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted in the tailgate handle and has a viewing angle of
130°.
Due to the high position of the camera
the rear bumper can be seen on the
display as a guide to position.
The area displayed by the camera is
limited. The distance of the image that appears on the display differs from
the actual distance.
Guiding lines
Dynamic guiding lines are horizontal
lines in 1 metre intervals projected on
the picture to define the distance to
shown objects.
Trajectory lane of the vehicle is
shown in accordance with the
steering angle.
The function can be deactivated in the
menu Settings in the Info-Display.
Vehicle personalisation 3 100.
Warning symbols
Warning symbols are indicated as
triangles 9 on the picture which show
obstacles detected by the rear
sensors of the advanced parking
assist.

148Driving and operating
FaultThe traffic sign assistant system may
not operate correctly when:
■ The area of the windscreen, where the front camera is located, is not
clean.
■ Traffic signs are completely or partially covered or difficult to
discern.
■ There are adverse environmental conditions, e.g. heavy rain, snow,
direct sunlight or shadows. In this
case No Traffic Sign Detection due
to Weather is indicated on the
display.
■ Traffic signs are incorrectly mounted or damaged.
■ Traffic signs do not comply with the
Vienna Convention on traffic signs
(Wiener Übereinkommen über
Straßenverkehrszeichen).Caution
The system is intended to help the driver within a defined speed
range to recognise certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not recognise
any other than the conventional
traffic signs that might give or end
a speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
■ no operation of turn signals
■ no brake pedal operation
■ no active accelerator operation or speeding-up
■ no active steering
If the driver is active, no warning will
be issued.
Activation
The lane departure warning system is activated by pressing ). The
illuminated LED in the button
indicates that the system is switched
