126Driving and operating
Activation of the functionalitySetting speed by the driver
The adaptive cruise control has to be
switched on manually at a speed
between 30 km/h and 180 km/h. For
vehicles with automatic transmission, the automatic selector lever must be
in position D or M.
Accelerate to the desired speed and
move the thumb wheel to SET/-. The
current speed is stored and
maintained.The speed value is indicated in the
Driver Information Centre.
The preset speed can then be
changed by moving thumb wheel to
RES/+ to increase or SET/- to
decrease the speed. Move thumb
wheel repeatedly to change speed in
small steps, move and hold to change speed in large steps.
When the adaptive cruise control is
operating, the stop-start system is
automatically deactivated.
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.
132Driving and operatingAs a safety measure, do not use the
system if the brake lights are faulty.
Do not use the system if the front
bumper is damaged.
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles and
pedestrians directly ahead, when the
driver does not actively take action
either by manual braking or by
steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert.
Forward collision alert 3 135
Front pedestrian protection 3 137
Active emergency braking can be
deactivated in the vehicle
personalisation 3 77. If deactivated,
m illuminates in the instrument
cluster and a warning message is
displayed in the Driver Information
Centre. When ignition is switched on next time, system is activated.The feature uses various inputs (e.g.
camera sensor, radar sensor, brake
pressure, vehicle speed) to calculate
the probability of a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system may not react to
animals. After a sudden lane
change, the system needs a
certain time to detect the next
preceding vehicle.
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
9 Warning
The usage of a license plate
support may have an impact on
the proper operation of the radar
unit and may limit sensor
perfomance. Vehicles or
pedestrians driving or walking
ahead may not be detected by the
system.
Do not use a a license plate
support to ensure proper system
functionality.
Functionality
Depending on the vehicle
configuration and the detected
objects, there are several operational speed ranges.
On vehicles equipped only with front
camera, the active emergency
braking operates from 5 km/h to 80 km/h when a vehicle has been
detected.
On vehicles equipped with radar
sensor and front camera, the active
emergency braking operates from
5 km/h to 140 km/h when a vehicle
has been detected.
Active emergency braking only works when the seat belts of the front
passengers are fastened.
134Driving and operating9Warning
Smart brake assist may increase
vehicle braking in situations when
it may not be necessary. You
could block the flow of traffic. If this occurs, take your foot off the brakepedal and then apply the brakes
as needed.
Forward collision alert 3 135.
Front pedestrian protection 3 137.
System limitations In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to various
types of objects, i.e., traffic signs or
vehicles in another lane. This is
normal operation, the vehicle does
not need service. Firmly apply the
accelerator pedal to override the
automatic braking if the situation and
the surroundings permit.
In the following cases, active
emergency braking performance
might be limited:
● driving on winding or hilly roads
● detecting vehicles with a trailer, tractors, muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● the sensor in the windscreen or the radar unit behind the front
bumper are blocked by snow, ice,
slush, mud, dirt etc.
● the windscreen is damaged or affected by foreign objects, e.g.
stickers
the bumper is damaged or
affected by foreign objects, e.g.
license plate support
Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when towing a trailer or caravan
● when carrying long objects on roof bars or a roof rack
● when the vehicle is being towed with the engine running
● when the vehicle is fitted with snow chains
● when a spare wheel is fitted that is smaller than the other wheels
● before using an automatic car wash with the engine running
● before placing the vehicle on a rolling road in a workshop
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
● if the brake lights are not working
Fault
In case the system requires a service,
a message is displayed in the Driver
Information Centre.
Driving and operating135If the system does not work properly,
vehicle messages are displayed in
the Driver Information Centre.
Vehicle messages 3 76.
Forward collision alert The forward collision alert may help toavoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera in the windscreen and
depending on the vehicle
configuration a radar unit located
behind the front bumper to detect a
vehicle directly ahead, in the path.
If a vehicle directly ahead is
approached too quickly, a warning
chime sounds and a message is
displayed in the Driver Information
Centre.9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
9 Warning
The usage of a license plate
support may have an impact on
the proper operation of the radar
unit and may limit sensor
perfomance. Vehicles driving
ahead, pedestrians or other
objects located in front of the
vehicle may not be detected by the
system.
Do not use a license plate support on the front bumper to ensure
proper system functionality.
Activation
Depending on the vehicle
configuration and the detected
objects, there are several operational speed ranges.
On vehicles equipped only with front
camera, the forward collision alert
operates from 5 km/h to 80 km/h
when a vehicle has been detected.
136Driving and operatingOn vehicles equipped with radar
sensor and front camera, the forward
collision alert operates from 5 km/h to

Selecting the alert sensitivity
Three alert sensivities can be
selected in the settings of the active
emergency braking within the vehicle personalisation 3 77.
The chosen setting will be memorised
when the ignition has been switched
off. The alert timing will vary based on
selected alert setting and vehicle
speed. Consider traffic and weather conditions when selecting the alert
timing.
Deactivation
The system can only be deactivated
by deactivating the active emergency braking in the vehicle personalisation
3 77. When ignition is switched on
next time, system is activated.
System limitations Forward collision alert is designed to
warn on vehicles, but may react also
to other objects.
Driving and operating137In the following cases, forward
collision alert may not detect a vehicle
ahead or sensor performance is
limited:
● driving on winding or hilly roads
● driving during nighttime
● weather limits visibility, such as fog, rain, or snow
● the sensor in the windscreen or the radar unit behind the front
bumper are blocked by snow, ice, slush, mud, dirt etc.
● the windscreen is damaged or affected by foreign objects, e.g.
stickers
Front pedestrian protection
Front pedestrian protection may help
to avoid or reduce the harm caused
by front-end crashes with pedestrians when driving forward.
The system uses the front camera in
the windscreen and depending on the vehicle configuration a radar unit in
the front bumper to detect a
pedestrian directly ahead in the path.
9 Warning
The usage of a license plate
support may have an impact on
the proper operation of the radar
unit and may limit sensor
perfomance. Vehicles or
pedestrians driving or walking
ahead may not be detected by the
system.
Do not use a a license plate
support to ensure proper system
functionality.
Front pedestrian protection can
detect and alert to pedestrians in a
forward gear at speeds between
5 km/h and 60 km/h. Additionally,
front pedestrian protection can
provide a boost to braking or
automatically brake the vehicle.
During nighttime driving, system
performance is limited.
9 Danger
Front pedestrian braking does not
provide an alert or automatically
brake the vehicle, unless it detects
a pedestrian.
The system may not detect
pedestrians, including children,
when the pedestrian is not directly ahead, not fully visible, not
standing upright, or when part of a
group.
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

● 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.
