Driving and operating183Forward collision alert 3 181
Front pedestrian protection 3 185
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 85 km/h.
The system detects stationary
vehicles only if the speed does not
exceed 80 km/h.
A precondition is that active
emergency braking is not deactivated
in the vehicle personalisation menu
3 118.
If deactivated, m illuminates in the
instrument cluster and a warning
message is displayed in the Driver
Information Centre
If the system has been deactivated
manually, it is reactivated
automatically the next time the
ignition is switched on.
The system includes: ● emergency automatic braking
● forward collision alert
● front pedestrian protectionEmergency 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 situation, the
vehicle may automatically brake
moderately or hard.
Front automatic braking can only
occur if a vehicle or a pedestrian
ahead is detected.
Forward collision alert 3 181
Front pedestrian protection 3 185
Below a speed of 30 km/h,
emergency automatic braking may
slow down the vehicle to a complete
stop. If the speed exceeds 30 km/h, emergency automatic braking
reduces the speed. However, the
driver must apply the brake.
Driving and operating185Fault
In case the system requires a service, m is illuminated in the instrument
cluster, a message is displayed in the Driver Information Centre and an
audible signal is given.
If the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.
Vehicle messages 3 117.
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
5 km/h and 60 km/h.
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.
Front pedestrian protection includes:
● detecting front pedestrian ahead● front pedestrian alert
Front pedestrian protection is
activated together with forward
collision alert.
Forward collision alert 3 181.
Detecting front pedestrian ahead
A pedestrian ahead up to a distance
of approx. 40 m is indicated by a
symbol in the instrument cluster.
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
5 km/h to 60 km/h in forward gear
● the distance to an pedestrian ahead is more than 40 m
● driving on winding or hilly roads
● driving during nighttime
● weather limits visibility, such as fog, rain, or snow
Driving and operating189
Additionally, the distance to rear, front
and lateral obstacles is displayed by
changing distance lines in the Colour
Info Display 3 113.
Deactivation
The system is deactivated
automatically when vehicle speed
exceeds 10 km/h, by applying the electric parking brake or by pressing
the parking assist button ¼.
Graphic Info Display: The system is
switched off when the LED in the
parking assist button ¼ is illuminated.

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.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.
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.

suggested parking slot.
Surface irregularities, e.g. on
construction zones, are not detected
by the system. The driver accepts
responsibility.
Side blind spot alert The side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
blind spot zone. The system displays
a visual alert in each exterior mirror,
when detecting objects that may not
be visible in the interior and exterior
mirrors.
Side blind spot alert uses some of the
advanced parking assist sensors
which are located in the front and rear bumper on both sides of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:

Lane keep assist
Lane keep assist helps to avoid
crashes due to unintentional lane
departures. A front camera located at the top of the windscreen observes
the lane markings between which the
vehicle is driving. If the vehicle
approaches a lane marking, the
steering wheel is gently turned to
position the vehicle back into the lane. The driver will then notice a turning
movement of the steering wheel. Turn
steering wheel in same direction, ifsystem steers not sufficient. Turn
steering wheel gently into opposite
direction, if lane change is intended.
When the system steers to correct the trajectory of the vehicle, a flashes
yellow in the instrument cluster.
A warning message in the Driver
Information Centre accompanied by a warning chime alerts the driver when
immediate driver´s action is required.
Unintended lane departure is not
assumed by the system when the turn lights are operated and during 20 s
after turn lights have been switched
off.
Note
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.
Following preconditions have to be
fullfilled:
