Adopting speed by the speed limit
recognition
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the speed limit
recognition. The detected speed limit
can be used as new value for the
cruise control.
Using the camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs.
With active cruise control the
recognised speed limit will be
displayed in the Driver Information
Centre and MEM illuminates if the
difference between set speed and
speed limit is more than 9 km/h.
Press MEM on the steering wheel to

Adopting speed by the speed limit
recognition
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the speed limit
recognition. The detected speed limit
can be taken over as new set speed
for the adaptive cruise control.
Using the camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs.
If the adaptive cruise control is active, the recognised speed limit will be
displayed in the Driver Information Centre and MEM illuminates if the
difference between set speed and
speed limit is more than 9 km/h.
Press MEM on the steering wheel to
request saving of the suggested
speed.
Press MEM on the steering wheel
once more to confirm and save the
new speed setting.
This speed limit is now the new set
speed of the adaptive cruise control.
Driving and operating129● The vehicle accelerates above180 km/h (manual and automatic
transmission) or slows down
below 30 km/h (manual
transmission).
● The electric parking brake is applied.
● The traction control system or electronic stability control is
deactivated or operating.
● The selector lever of automatic transmissions is neither in D nor
in M.
● A fault is detected in the electronic stability control or the
radar system.
● Immediately after the clutch pedal has been depressed or a
few seconds after the clutch
pedal has been depressed
(depending on the manual
transmission).
Switching off the system
Press w, the adaptive cruise control
mode is disabled and the adaptive
cruise control indication extinguishes
in the Driver Information Centre.Pressing 5 to activate the speed
limiter deactivates adaptive cruise
control.
Switching off the ignition deletes the
stored set speed.
Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it
again.
● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control of the vehicle.
● Do not use the adaptive cruise control during rain, snow or
heavy dirt, as the radar sensor
can be covered by a water film,
dust, ice or snow. This reduces or suppresses completely the
visibility. In case of sensor
blockage, clean the sensor
cover.
● Do not use the system when the spare wheel is in use.System limits9Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles only
at low speed.
148Driving and operatingActive side blind spot detection
operates when the vehicle speed is
between 65 and 140 km/h.
Functionality
When steering towards the detected
vehicle is attemped, the driver will
then notice a turning movement of the
steering wheel towards the opposite
side. Turn steering wheel in the same direction if the system does not steer
sufficiently.
The system also intervenes even if
the turn lights have been activated.
Panoramic view system
This system allows views of the
vehicle's surroundings to be
displayed as a nearly 180° picture in
the Info Display, like a bird's eye view.
The system uses: ● rear camera, installed in the rear bumper
● ultrasonic parking sensors in the rear bumper
The screen in the Info display is
divided into two parts. On the right
there is a view from above the vehicle,
and on the left there is the view from
the rear displayed. The parking
sensors complete the information on
the view from above the vehicle.
Activation
The panoramic view system is
activated by:
● engaging reverse gear
● driving up to 13 km/h
Functionality
Different views can be selected in the left part of the display. Change the
type of view at any time during a
manoeuvre by pressing the touch
field in the left lower zone of the
display and selecting a view from the
view selection menu:
● Standard view
● Auto mode
● Zoom view
● 180° view
The display is immediately updated
with the type of view selected.
Auto mode is activated by default. In
this mode, the system selects the
best view, standard or zoom, to
display according to the information
from the parking sensors.
The state of the system is not kept in
memory when the ignition is switched
off.
Driving and operating149Standard view
The area behind the vehicle is
displayed in the screen. The vertical
lines represent the width of the
vehicle with mirrors unfolded. The
direction of the lines changes with the position of the steering wheel.
The first horizontal line represents a
distance of about 30 cm beyond the
edge of vehicle's rear bumper. The
upper horizontal lines represent
distances of about 1 m and 2 m.
This view is available in auto mode or
in the view selection menu.
Auto mode
This mode is activated by default.
Using sensors in the rear or in the
front bumper, the automatic view
changes from rear view or front view
to a view from above, as an obstacle is approached during a manoeuvre.
Zoom view
The camera records the vehicle's
surroundings during the manoeuvre
in order to reconstruct a view fromabove the rear or the front of the
vehicle in its near surroundings.Thus,
the vehicle can be manoeuvred
around obstacles nearby. This view is available with auto mode or in the
view selection menu.
180° view
The 180° view facilitates reversing
out of a parking bay, making it
possible to see the approach of
vehicles, pedestrians and cyclists.
This view is not recommended for
carrying out a complete manoeuvre.
It is made up of three areas: left 1,
centre 2 and right 3. This view is
available from the view selection menu only.
152Driving and operating
The system recognises the traffic
signs above and displays them in the
Driver Information Centre.
9 Warning
The actual traffic sign always
takes priority over the traffic sign displayed in the Driver Information Centre.
If the vehicle enters a road of whichthe entry is prohibited, the no entry
traffic symbol and a warning message are displayed in the Driver
Information Centre. If the system
detects one of the other traffic signs,
the respective traffic sign is displayed
in the Driver Information Centre.

Lane keep assist
Lane keep assist supports the driver
to avoid unintended leaving of the
lane. The front camera observes road
edges, as well as the lane markings
between which the vehicle is driving.
If the vehicle approaches a road edge or a lane marking, the steering wheel
is gently turned to position so that the
vehicle turns back into the lane. The
driver will then notice a turning
movement of the steering wheel. Turn steering wheel in same direction, if
the system does not steer sufficiently.
Turn steering wheel gently into
opposite direction, if lane change is
intended.
When the system steers to correct the trajectory of the vehicle, L flashes
yellow in the instrument cluster.
Unintended lane departure is not
assumed by the system when the turn lights are operated and during few
seconds after turn lights have been
switched off.Note
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.
Following preconditions have to be
fulfilled:
● vehicle speed must be between 65 km/h and 180 km/h
● the driver must hold the steering wheel
● the turn lights are not activated
● the electronic stability control is activated and not in operation
● the vehicle is not connected to a trailer or an electric bicycle carrier
● normal driving behaviour (system
detects dynamic driving style, i.e. pressure on the brake or
accelerator pedal)
● roads with good lane markings ● no spare wheel is used
● the driver is not taking the hands off the steering wheel for a longer
time period
● the vehicle is not driven in a tight
corner
Driving and operating153Activation
If the system is activated, the LED in
the button j is not illuminated. To
activate the system when the system
is deactivated, press j.
The system is operational at vehicle
speeds between 65 km/h and
180 km/h and if lane markings are
detectable. The driver must hold the
steering wheel. The electronic
stability control system must be
activated.
The control indicator L flashes
yellow during trajectory correction.
If the driver wishes to maintain the
trajectory of the vehicle, he can
interrupt the correction by keeping a
firm grip on the steering wheel, e.g.
during an avoiding manoeuvre. The
correction is interrupted if the turn
lights are operated. If the vehicle is
equipped with active side blind spot detection, the interruption of the lane
correction might be cancelled.
Side blind zone assistant 3 146.
There is no correction triggered when
the turn lights are operated and
during few seconds after turn lights
have been switched off.
If the system detects that the driver is not holding the steering wheel
permanently, it interrupts the
correction. A warning message in the
Driver Information Centre
accompanied by a warning chime
alerts the driver when immediate
driver´s action is required.Deactivation
To deactivate the system, press and
hold j. Deactivation of the system is
confirmed by the illuminated LED in
the button and L illuminates yellow
in the instrument cluster.
Fault
In the event of a fault, L and C
appear in the instrument panel,
accompanied by a display message
and a warning chime. Contact a
dealer or a qualified workshop to have the system checked.
