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 to
detect a preceding vehicle directly
ahead, in your path.
If a vehicle directly ahead is
approached too quickly, a warning
chime and alert in the Driver
Information Centre is provided.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.
146Driving and operatingActivation
Forward collision alert detects
vehicles and operates automatically
at all speeds above 3 mph and
53 mph. The system detects
stationary vehicles if the speed does
not exceed 50 mph.
Alerting the driver The driver is warned by following
alerts:
● Symbol , illuminates and a
warning message is displayed in
the Driver Information Centre
when the distance to the vehicle
ahead gets to small.
● Symbol , illuminates, a warning
message is displayed in the
Driver Information Centre 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

Caution
The colour lighting of this control
indicator does not correspond to
local traffic laws on following
distance. The driver bears full
responsibility for maintaining safe
following distance according to
applicable traffic rules, weather
and road conditions etc. at all
times.
Selecting the alert sensitivity
The alert sensitivity has to be set to
close, normal or distant in the vehicle personalisation menu 3 96.
The chosen setting will remain until it
is changed. The alert timing will vary
based on vehicle speed. The faster
the vehicle speed, the farther away
the alert will occur. 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 96.
System limitations Forward collision alert is designed to
warn on vehicles only, but may react
also to other objects.
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.
● the windscreen is damaged or affected by foreign objects, e.g.
stickers
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
148Driving and operatingsituation, the vehicle may
automatically brake moderately or
hard. This front automatic braking can
only occur if a vehicle or a pedestrian ahead is detected.
Forward collision alert 3 145.
Front pedestrian protection 3 149.
Emergency automatic braking may slow the vehicle to a complete stop to
try to avoid a potential crash.9 Warning
Emergency automatic braking is
an emergency crash preparation
feature and is not designed to
avoid crashes. Do not rely on the
system to brake the vehicle.
Emergency automatic braking will
not brake outside of its operating speed range and only responds to
detected vehicles and
pedestrians.
Forward looking brake assist
In addition to emergency automatic
braking, the forward looking brake
assist function makes the brake assist
more sensitive. Therefore, pressing
the brake pedal less strongly results in immediate hard braking. This
function helps the driver brake
quicker and harder before the
imminent collision.9 Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is designed to reduce the vehicle
speed before a collision. It may not
react to animals. After a sudden
lane change, the system needs a
certain time to detect the next
preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the brakes and steer to avoid
collisions.
The system is designed to work with
all occupants wearing their seat belts.
Forward collision alert 3 145.
Front pedestrian protection 3 149.
System limitations In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
pedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving in the dark
● windscreen damaged or stickered
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.
150Driving and operatingFront 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 37 mph in forward gear
● the distance to an pedestrian ahead is more than 40 m
● driving on winding or hilly roads
● driving in the dark
● weather limits visibility, such as fog, rain, or snow● the sensor in the windscreen isblocked by snow, ice, slush, mud,dirt etc.
● the windscreen is damaged or affected by foreign objects, e.g.

Parking assist
General information The system is switched off
automatically when attaching a trailer
or bike carrier to the trailer hitch.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.
The parking assist makes parking easier by measuring the distance
between the vehicle and obstacles. It
informs and warns the driver by giving acoustic signals and display
indication.
Acoustic signals are given on the side
on which the vehicle is closer to an
obstacle. The interval between the sounds becomes shorter as the
vehicle gets closer to that obstacle.
When the distance is less than
approx. 30 cm, the sound is
continuous.
Rear parking assist
The system operates with ultrasonic
parking sensors in the rear bumper.
Activation
Rear parking assist is activated when reverse gear is engaged.
Driving and operating151The system is ready to operate when
the LED in the parking assist button
¼ is not illuminated.
Indication
The system warns the driver with acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
50 cm.
Additionally, the distance to rear
obstacles is displayed by changing
distance lines in the Info Display
3 91 . When the obstacle is very close,
9 for danger is displayed in the
screen.
Deactivation
The system is switched off when
reverse gear is disengaged. Press ¼
to deactivate the system manually.
The LED in the button illuminates
when the system is deactivated. If the
system has been deactivated
manually, it is not reactivated
automatically the next time the
ignition is switched on.
Front-rear parking assist
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.
The system operates with ultrasonic
parking sensors in the rear and front
bumper.
Activation
Rear parking assist is activated when reverse gear is engaged.
In addition to the rear parking assist,
the front parking assist is triggered
when an obstacle is detected in front
and the speed of the vehicle is still
below 6 mph.
The system is ready to operate when
the LED in the parking assist button
¼ is not illuminated.
