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
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 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.
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
Page 138 of 227

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