Driving and operating131display of a message in the
instrument panel, accompanied by an
audible signal.
The adaptive cruise control may not
operate correctly if traffic signs do not
comply with the Vienna Convention
on Road Signs and Signals.
Have the system checked by a dealer or a qualified workshop.
As 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 3 134
Front pedestrian protection 3 136Active emergency braking can be
deactivated in the vehicle
personalisation 3 76. If deactivated,
m illuminates in the instrument
cluster and a warning message is
displayed in the Driver Information Centre. When ignition is switched onnext 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 3 mph to 50 mph when a vehicle has been
detected.

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.
● the windscreen is damaged or affected by foreign objects, e.g.
stickers
● the front bumper is damaged or affected by foreign objects, e.g.
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.
