Driving and operating219Emergency automatic brakingAfter 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. Depending on the
situation, the vehicle may
automatically brake moderately or
hard. This front automatic braking can
only occur if a vehicle ahead is
detected, indicated by the vehicle
ahead indicator A 3 214 . On vehicles
with front pedestrian protection, front automatic braking can also occur
when a pedestrian ahead is detected,
indicated by the pedestrian ahead
indicator 7.
If equipped only with front camera the system operates up to a speed of 50
mph.
Below a speed of 25 mph the system
can apply full braking.
Emergency automatic braking may
slow the vehicle to a complete stop to
try to avoid a potential crash. If this
happens, emergency automatic
braking may engage the electricparking brake to hold the vehicle at a
stop. To release press the electric
parking brake button or firmly press
the accelerator pedal.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 the brake preparation
system and 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.
If equipped only with front camera the
system operates up to a speed of 53
mph.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.
Intelligent Brake Assist
If the vehicle is equipped with radar
sensor Intelligent brake assist may
activate when the brake pedal is
220Driving and operatingapplied quickly by providing a boost
to braking based on the speed of approach and distance to a vehicle
ahead.
Minor brake pedal pulsations or pedal movement during this time is normal
and the brake pedal should continue to be applied as needed. Intelligent
brake assist will automatically
disengage only when the brake pedal is released.9 Warning
Intelligent brake assist may
increase vehicle braking in
situations when it may not be
necessary. You could block the
flow of traffic. If this occurs, take
your foot off the brake pedal and
then apply the brakes as needed.

Deactivation
Active emergency braking can be
deactivated in the personalisation
menu 3 123. If deactivated a
message is displayed in the Driver
Information Centre.
We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when the vehicle is being towed
● before using an automatic car wash with ignition switched on
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
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 acceleratorpedal 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.
● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,dirt, windscreen damage or
affected by foreign items, e.g.
stickers.
To avoid malfunction keep the areas
of the camera sensor in the
windscreen and the radar sensor in
the radiator grille always clean from
dirt, dust, ice and snow.
Driving and operating221Complete 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.
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

Front pedestrian protection Front pedestrian protection may help
to avoid or reduce the harm caused
by front-end crashes with nearby
pedestrians when driving in a forward
gear.
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 5mph and 50 mph. Additionally Front
pedestrian protection can provide a
boost to braking or automatically
brake the vehicle.
During daytime driving, the system
detects pedestrians up to a distance
of approximately 40 metres. During
nighttime driving, system
performance is limited.
Front pedestrian protection can be
set to Off, Alert, or Alert & Brake in
vehicle personalisation 3 123.9 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
● automatic braking
Detecting front pedestrian ahead
A pedestrian ahead up to a distance
of approximately 40 m is indicated by the control indicator 7 in the
instrument cluster. On vehicles with
head-up display, 7 is projected on the
windscreen.

Centre.
System limitations Occasional missed alerts can occur
under normal circumstances or in
sharp curves. The system can
temporarily alert of objects in the blind spot at specific weather conditions
(rain, hail etc). Driving on a wet road
or in the transitions from a dry area to
a wet area can cause the control
indicator F to light up, as water
splash can be interpreted as an object. Otherwise the control indicator F may illuminate due to guardrails,
signs, trees, shrubs or other immobile objects. This is normal operation and
the system does not need to be
serviced.The system may not operate properly
when:
● Ice, snow, mud, stickers, magnets, metal plates, or
anything else covers the sensors.
● Driving in heavy rainstorms. ● The vehicle had an accident or if the area surrounding the
detection sensor is damaged or
not properly repaired.
● There are extreme temperature changes.
● The vehicle is towing a trailer
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.

242Driving and operatingCaution
The system is intended to help thedriver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane keep assist
Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
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. Turn steering wheel in same
direction, if system steering is not
sufficient. Turn steering wheel gently
into opposite direction, if lane change is intended.
When crossing a lane marking
significantly, lane keep assist starts a
visual and acoustic warning.
Additionally, the status of the lane
keep assist is indicated on the Driver
Assistance page in the Driver
Information Center 3 111.
Unintended lane departure is
assumed
● without using turn signal● using the turn signal in the opposite direction of the lane
departure
● without braking
● without acceleration
● without active steering.Notice
The system is switched off during
detection of ambiguous lane
markings, e.g. in construction areas.
Notice
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.
Activation
The lane keep assist is activated by
pressing a. The LED in the button
illuminates to indicate that the system
is switched on.
