Fault
In case the system requires a service, a message is displayed in the Driver
Information Centre.
If the system does not work properly,
vehicle messages are displayed in
the Driver Information Centre.
Vehicle messages 3 75.
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

Driving and operating135objects 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 3 mph to 50 mph when
a vehicle has been detected.
On vehicles equipped with radar
sensor and front camera, the forward
collision alert operates from 3 mph to
87 mph when a vehicle has been
detected.
Alerting the driver
The driver is warned by following
alerts:
● Symbol , and a warning
message are displayed in the
Driver Information Center, when
the distance to the vehicle ahead
gets to small.
● Symbol , and a warning
message are displayed in the
Driver Information Center and a
warning chime sounds, when a
collision is imminent and
immediate driver's action is
required.9 Warning

Selecting the alert sensitivity
Three alert sensivities can be
selected in the settings of the active
emergency braking within the vehicle personalisation 3 76.
The chosen setting will be memorised
when the ignition has been switched
off. The alert timing will vary based on

136Driving and operatingselected 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 76. 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.
In 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 orthe 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 inthe 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
3 mph and 37 mph. Additionally, front pedestrian protection can provide a
boost to braking or automatically
brake the vehicle.
During nighttime driving, system
performance is limited.

Driving and operating1379Danger
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.
The system can only be deactivated
by deactivating the active emergency braking in the vehicle personalisation
3 76. When ignition is switched on
next time, system is activated.
Front pedestrian alert When approaching a detected
pedestrian too quickly, a warning
message is displayed in the Driver
Information Centre. A warning chime
is provided.
Cruise control or adaptive cruise control may be disengaged when the
front pedestrian alert occurs.
System limitations
In the following cases, front
pedestrian protection may not detect
a pedestrian ahead or sensor
performance is limited:
● vehicle speed is out of range from
3 mph to 50 mph in forward gear
● driving on winding or hilly roads
● driving in the dark
● 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.

license plate supportParking assist
General information
When attaching a trailer or bicycle
carrier to the trailer hitch, the parking
assist is deactivated.9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
Rear parking assist
The system warns the driver with
acoustic signals and display
indication against potentially
hazardous obstacles behind the
vehicle while reverse gear is
engaged.

140Driving and operatingDepending on which side of the
vehicle is closer to an obstacle, you will hear acoustic warning signals inthe vehicle on the respective side.
The interval between the sounds
becomes shorter as the vehicle gets
closer to that obstacle. When the
distance is less than approx. 30 cm,
the sound is continuous.
Additionally, the distance to rear and
front obstacles is displayed by
changing distance lines in the Info Display 3 74.
If the vehicle stops for more than
3 seconds in a forward gear, if
automatic transmission is in P
position or if no further obstacles are
detected, no acoustic warning signals
are given.
Deactivation
The system is deactivated
automatically when vehicle speed
exceeds 6 mph, by applying the
electric parking brake or by pressing
the parking assist button e.
When the system is deactivated
manually, the LED in the button
illuminates.
If the system has been deactivated
manually, it is not reactivated
automatically the next time the
ignition is switched on.
System limitations
In the event of a fault or if the system does not work temporarily, e.g.
because of high external noise level
or other interference factors, C
illuminates in the instrument cluster. A message is displayed in the Driver
Information Centre and a warning
chime sounds.9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and correct distance indication in the
upper part of these vehicles
cannot be guaranteed.

Customer information215Vehicle data recording
and privacy
Event data recorders Electronic control units are installed in
your vehicle. Control units process
data which is received by vehicle
sensors, for example, or which they
generate themselves or exchange
amongst themselves. Some control
units are necessary for the safe
functioning of your vehicle, others
assist you while you drive (driver
assistance systems), while others
provide comfort or infotainment
functions.
The following contains general
information about data processing in
the vehicle. You will find additional
information as to which specific data
is uploaded, stored and passed on to third parties and for what purpose in
your vehicle under the key word Data Protection closely linked to the
references for the affected functional
characteristics in the relevant owner's
manual or in the general terms of
sale. These are also available online.Operating data in the vehicle
Control units process data for
operation of the vehicle.
This data includes, for example: ● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate,
"seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient and is not stored for longer than an
operational cycle, and only processed
on board the vehicle itself. Often
control units include data storage
(including the vehicle key). This is
used to allow information to be
documented temporarily or
permanently on vehicle condition,
component stress, maintenance
requirements and technical events
and errors.Depending on technical equipment
levels, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used where necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.
