Driving and operating147In the following cases, forward
collision alert may not detect a vehicle
ahead or sensor performance is
limited:
● driving on winding or hilly roads
● driving in the dark
● weather limits visibility, such as fog, rain, or snow
● the sensor in the windscreen is blocked by snow, ice, slush, mud,dirt etc.

Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles, pedestrians and obstacles directly ahead, when a
collision can no longer be avoided
either by manual braking or by
steering. Before the active
emergency braking applies, the driver is warned by the forward collision
alert or the front pedestrian protection
alert.Forward collision alert 3 145.
Front pedestrian protection 3 149.
The feature uses various inputs (e.g.
camera 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.
Functionality
Active emergency braking is
equipped with a front camera and
operates in forward gear in the range
between walking speed and 53 mph.
The system detects stationary
vehicles only if the speed does not
exceed 50 mph.
A precondition is that forward collision
alert with front camera system is not
deactivated in the vehicle
personalisation menu 3 96.
The system includes: ● emergency automatic braking● forward looking brake assist
● forward collision alert
● front pedestrian protection
Emergency automatic braking
After activation of brake preparation
system and just before the imminent
collision, this function automatically
applies limited braking to reduce the
impact speed of the collision or
prohibit a crash. If active emergency
braking is applied, m flashes in the
instrument cluster. Depending on the
Driving and operating149Complete 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 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
Active emergency braking can be
deactivated in the personalisation
menu 3 96. If deactivated, milluminates in the instrument cluster
and a warning message is displayed
in the Driver Information Centre.
Fault
In case the system requires a service,
a message is displayed in the Driver
Information Centre.
If the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.
Vehicle messages 3 95.
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 to detect a pedestrian
directly ahead in your path.
Front pedestrian protection can
detect and alert to pedestrians in a
forward gear at speeds between
3 mph and 37 mph.During driving in the dark, 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.
Front pedestrian protection includes:
● detecting front pedestrian ahead● front pedestrian alert
Front pedestrian protection is
activated together with forward
collision alert.
Forward collision alert 3 145.
Detecting front pedestrian ahead
A pedestrian ahead up to a distance
of approx. 40 m is indicated by a
symbol in the instrument cluster.
152Driving and operatingIndication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles in front of the
vehicle and behind the vehicle by using the respective loudspeakers.
Additionally, the distance to rear and
front obstacles is displayed by
changing distance lines in the Info Display 3 91.
Deactivation
The system is deactivated
automatically when vehicle speed
exceeds 6 mph or if the vehicle stops
for more than 3 seconds in a forward gear or if no further obstacles aredetected.
