Driving and operating167System limits9Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● Adaptive cruise control does ignore the oncoming traffic.
● Adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● Adaptive cruise control considers
stopped vehicles only at low
speed.
● Do not use adaptive cruise control when towing a trailer.
● Do not use adaptive cruise control on roads with an incline ofmore than 10%.
As the radar's field of detection is
quite narrow, it is possible that the
system may not detect:
● Vehicles of reduced width (motorcycles, scooters...).
● Vehicles not running in the middle of the lane,
● Vehicles entering a corner.
● Vehicles suddenly pulling out.
Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may lose the current vehicle ahead or
consider a vehicle which is not in the
actual lane. This can happen when
entering or exiting a bend or if the
bend gets stronger or weaker. If it no
longer detects any vehicle ahead,
then control indicator A will
extinguish.
If the centrifugal force is too high in a bend, the system slows down the vehicle slightly. This braking level is
not designed to avoid spinning-off the
bend. The driver is responsible for
reducing the selected speed before
entering a bend and in general to
adapt the speed to the road type and
to existing speed limits.
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.

Driving and operating1719Warning
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
If equipped only with front camera the
active emergency braking operates in forward gear above walking speed up
to 53 mph. With radar sensor and
front camera active emergency
braking operates in forward gear
above walking speeds to 87 mph.
A precondition is that forward collision
alert with front camera system is not
deactivated in the vehicle
personalisation menu 3 104.
The system includes: ● brake preparation system
● emergency automatic braking ● forward looking brake assist
● intelligent brake assist (only with radar sensor)
● forward collision alert
● front pedestrian protection
Brake preparation system
When approaching a vehicle ahead
or a pedestrian so quickly that a
collision is likely, the brake
preparation system slightly
pressurizes the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that braking can occur more rapidly.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. 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 3 169 . On vehicles with front
pedestrian protection, front automatic
braking can also occur when a
pedestrian ahead is detected.
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 electric
parking brake to hold the vehicle at a stop. To release press the electric
parking brake button or firmly press
the accelerator pedal.

190Driving and operating● Driving on banked roads.
● Driving on road edges.
● Driving on roads with poor lane markings.
● Sudden lighting changes.
The system can not operate when no
lane marking is detected.
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 steers 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.Unintended lane departure is
assumed
● without using turn signal
● 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.
ActivationAfter ignition is switched on, lane
keep assist is activated. If the system is activated, the LED in the button Ó
is not illuminated . To activate the
system when the system is
deactivated, press Ó.
When the control indicator a in the
instrument cluster illuminates green,
the system is ready to assist.
The system is operational at vehicle
speeds between 40 mph and
112 mph and if lane markings are
available. The driver must hold the
wheel with both hands. The change of trajectory is not accompanied by
operation of the direction indicators.
The ESC system must be activated.
The system makes the correction to
the trajectory necessary to return the
vehicle to its initial path if it identifies
a risk of the vehicle involuntarily
crossing one of the lane markings
detected. The driver will then notice a
turning movement of the steering
wheel.
