Adaptive cruise control
Adaptive cruise control is an
enhancement to conventional cruise
control with the additional feature of
maintaining a certain distance behind the vehicle ahead. It uses radar and
camera sensors to detect the vehicles
ahead. If no vehicle is detected in the driving path, the adaptive cruise
control will behave like a conventional
cruise control.
Adaptive cruise control automatically
decelerates the vehicle when
approaching a slower moving vehicle.
It then adjusts the vehicle speed to
follow the vehicle ahead at the
selected following distance. The
Driving and operating169bumper may appear to be intact,
however the sensor behind can be
out of position and react
incorrectly. After an accident,
consult a workshop to verify and
correct the adaptive cruise control
sensor position.
Fault
In the event of a fault with the cruise
control, you are alerted by the
illumination of a warning lamp and the
display of a message in the
instrument panel, accompanied by an
audible signal.
The adaptive cruise control may not
operate correctly if traffic signs do not comply with the Vienna Convention
on Road Signs and Signals (Wiener
Übereinkommen über
Straßenverkehrszeichen).
Have the system checked by a dealer
or a qualified workshop.
As a safety measure, do not use the
system if the brake lamps are faulty.
Do not use the system if the front
bumper is damaged.
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 and a
radar unit located behind the front
bumper of the vehicle to detect a
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.
Activation
Forward collision alert detects
vehicles and operates automatically
at all speeds above 3 mph and
87 km/h.
Alerting the driver The system triggers different level of
alerts depending on the risk of
collision detected. The alerts are
displayed in the instrument cluster.
Level 1: A visual alert is displayed.
Level 2: A visual alert is displayed and
an audible alert is triggered.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.
When the time to a potential collision
with a vehicle in front gets too small
and a collision is imminent, a warning is displayed in the Driver InformationCentre.
Simultaneously a warning chime sounds. Depress the brake pedal and
steer the vehicle, if it is required by the
situation.

deactivated in the personalisation
menu 3 104. If deactivated a
message is displayed in the Driver
Information Centre.
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.
● During nighttime driving.
● 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 items, e.g.
stickers.
Complete 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
displayed in the Driver Information
Centre.
Vehicle messages 3 103.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 and a radar unit in the front bumper 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. Additionally Front
pedestrian protection can provide a
boost to braking or automatically
brake the vehicle.
During nighttime driving, system
performance is limited.
Front pedestrian protection can be
set to Off, Alert, or Alert & Brake in
