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.
Page 138 of 229

136Driving and operatingOn vehicles equipped with radar
sensor and front camera, the forward
collision alert operates from 5 km/h to
140 km/h 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

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.

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.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
