172Driving and operatingthe windscreen 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.
The 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
vehicle speed increases or decreases
to follow the vehicle ahead, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
If the vehicle ahead accelerates or changes lane, the adaptive cruise
control progressively accelerates the
vehicle to return to the stored set
speed. If the driver operates the turn
lights to overtake a slower vehicle, the adaptive cruise control allows the
vehicle to temporarily approach the
vehicle ahead to help passing it.
However, the set speed will never be
exceeded.The adaptive cruise control can store
set speeds for manual transmission.
If the vehicle ahead is moving too
slowly and the selected following
distance cannot be maintained
anymore, a warning chime is given
and a message is displayed in the
Driver Information Centre. The
message prompts the driver to take
back control of the vehicle. On
vehicles with automatic transmission, the system can brake the vehicle until a full stop.
The adaptive cruise control can store
set speeds over 19 mph for manual
transmission. If the vehicle ahead is
moving too slowly and the selected
following distance cannot be
maintained anymore, a warning
chime is given and a message is
displayed in the Driver Information
Centre. The message prompts the driver to take back control of the
vehicle. On vehicles with automatic
transmission, the system can brake
the vehicle until a full stop.9 Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the button
Ñ have priority over any adaptive
cruise control operation.
Switching on the system
Press C, the symbol C is indicated in
the Driver Information Centre. The
system is still not active.
178Driving and operatingFault
In the event of a fault with the adaptive
cruise control, you are alerted by the
illumination of a warning light 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.
Have the system checked by a dealer
or a qualified workshop.
As a safety measure, do not use the
system if the brake lights are faulty.
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.
Activation
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.
Driving and operating181Emergency automatic braking may
slow the vehicle to a complete stop to
try to avoid a potential crash.
● Automatic transmission: If the vehicle comes to a complete
stop, automatic braking is
maintained for up to two
seconds. Keep the brake pedal
depressed to prevent the vehicle
from starting off again.
● Manual transmission: If the vehicle comes to a complete
stop, the engine may stall.
Operation of the function may be felt
by a slight vibration in the brake
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.
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 during nighttime
● windscreen damaged or stickeredComplete attention is always requiredwhile 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
Driving and operating195Rear side view / 180° view
The 180° view facilitates reversing
out of a parking bay, making it
possible to see the approach of
vehicles, pedestrians and cyclists.
This view is not recommended for
carrying out a complete manoeuvre.
It is made up of three areas: left 1,
centre 2 and right 3. This view is

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.
Notice
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:
● vehicle speed must be between 40 mph and 112 mph
● the driver must hold the steering wheel with both hands
Driving and operating199● the change of trajectory is notaccompanied by operation of theturn signals
● the Electronic Stability Control is activated and not in operation
● the vehicle is not connected to a trailer or an electric bicycle carrier
● normal driving behaviour (system
detects dynamic driving style, i.e. pressure on the brake or
accelerator pedal)
● roads with poor lane markings
● no spare wheel is used
● the driver needs to be active during the correction
● the vehicle is not driven in a tight
cornerActivation
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.
The system is operational at vehicle
speeds between 40 mph and
112 mph and if lane markings are
detectable. The driver must hold the
steering wheel with both hands. The Electronic Stability Control system
must be activated.
The control indicator a flashes
yellow during trajectory correction.
If the driver wishes to maintain the
trajectory of the vehicle, he can
prevent the correction by keeping a
firm grip on the steering wheel, e.g.
during an avoiding manoeuvre. The correction is interrupted if the turn
lights are operated.
There is no correction triggered when
the turn lights are operated and
during a few seconds after turn lights
have been switched off.
If the system detects that the driver is not holding the steering wheel firmly
enough during an automatic
correction of trajectory, it interrupts
the correction. A warning message in
the Driver Information Centre
accompanied by a warning chime
alerts the driver when immediate
driver´s action is required.
If the side blind spot alert is activated
and the driver is about to change the
lane, the system corrects the
trajectory of the vehicle despite the
activation of the turn lights if another
vehicle is detected in the side blind
spot zone.
202Driving and operatingdriver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent of the driver's level of vigilance.
The driver drowsiness detection is
reinitialised when the ignition has
been switched off for a few minutes or the speed remains below 40 mph for
a few minutes.
System limitations
In the following situations, the system
may not operate properly or even not operate at all:
● poor visibility caused by inadequate lighting of the
roadway, falling snow, heavy
rain, dense fog etc.● dazzle caused by headlights of oncoming vehicles, low sun,
reflections on damp roads,
leaving a tunnel, alternating
shade and light etc.
● windscreen area in front of the camera covered by dirt, snow,
stickers etc.
● no lane markings detected or multiple lane markings due to
roadworks
● close vehicles ahead
● winding roads or narrow roadsFuel
Fuel for petrol engines The petrol engines are compatible
with bio-fuels that conform to current
and future European standards and
and can be obtained from filling
stations:
Petrol that meets the EN228
standard, mixed with a biofuel
meeting the EN15376 standard.
Use fuel with the recommended
octane rating. A lower octane rating
can reduce engine power and torque
and slightly increases fuel
consumption.
