130Driving and operatingIf another vehicle enters your driving
path, adaptive cruise control will first
consider the vehicle when it is
completely in your path. Be ready to
take action and depress the brake
pedal if you need to brake more
quickly.
Hill considerations9 Warning
Do not use the adaptive cruise
control on steep hill roads.
System performance on hills depends
on vehicle speed, vehicle load, traffic
conditions and the road gradient. It
may not detect a vehicle in your path
while driving on hills. On steep hills,
you may have to use the accelerator
pedal to maintain your vehicle speed.
When going downhill you may have to brake to maintain or reduce your
speed.
Note that applying the brake
deactivates the system.
Radar unit
The radar unit is located in the middle of the front bumper.
9 Warning
The radar unit was aligned
carefully during manufacture.
Therefore, in the event of a front-
end impact, do not use the system.
The front bumper may appear to
be intact, however the sensor
behind may be affected and react
incorrectly. After an accident,
consult a workshop to verify and
adjust the radar unit position.9 Warning
The usage of a license plate
support may have an impact on
the proper operation of the radar
unit and may limit sensor
perfomance. Vehicles driving
ahead, pedestrians or other
objects located in front of the
vehicle may not be detected by the
system.
Do not use a license plate support on the front bumper to ensure
proper system functionality.
Fault
In the event of a fault with the adaptive cruise control, you are alerted by the
illumination of a warning light and the
Driving and operating131display 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.
Do not use the system if the front
bumper is damaged.
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles and
pedestrians directly ahead, when the driver does not actively take action
either by manual braking or by
steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert.
Forward collision alert 3 134
Front pedestrian protection 3 136Active emergency braking can be
deactivated in the vehicle
personalisation 3 76. If deactivated,
m illuminates in the instrument
cluster and a warning message is
displayed in the Driver Information Centre. When ignition is switched onnext time, system is activated.
The feature uses various inputs (e.g.
camera sensor, radar 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.9 Warning
The usage of a license plate
support may have an impact on
the proper operation of the radar
unit and may limit sensor
perfomance. Vehicles or
pedestrians driving or walking
ahead may not be detected by the
system.
Do not use a a license plate
support to ensure proper system
functionality.
Functionality
Depending on the vehicle
configuration and the detected
objects, there are several operational speed ranges.
On vehicles equipped only with front
camera, the active emergency
braking operates from 3 mph to 50 mph when a vehicle has been
detected.
Driving and operating1379Danger
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.
The system can only be deactivated
by deactivating the active emergency braking in the vehicle personalisation
3 76. When ignition is switched on
next time, system is activated.
Front 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 50 mph in forward gear
● driving on winding or hilly roads
● driving in the dark
● 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 objects, e.g.
stickers
● the front bumper is damaged or affected by foreign objects, e.g.
license plate supportParking assist
General information
When attaching a trailer or bicycle
carrier to the trailer hitch, the parking
assist is deactivated.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.
Rear parking assist
The system warns the driver with
acoustic signals and display
indication against potentially
hazardous obstacles behind the
vehicle while reverse gear is
engaged.
Driving and operating151System limitationsThe rear view camera may not
operate properly when:
● the surrounding is dark
● the beam of headlights is shining
directly into the camera lenses
● weather limits visibility, such as fog, rain, or snow
● the camera lenses are blocked by snow, ice, slush, mud, dirt.Clean the lense, rinse with water,
and wipe with a soft cloth
● the vehicle is towing an electrically connected trailer,
bicycle carrier, etc.
● the vehicle had a rear end accident
● there are extreme temperature changes
Traffic sign assistant
The traffic sign assistant is an
extension of the speed limit
recognition available for speed
limiter, cruise control and adaptive
cruise control.
The system recognises the traffic signs above and displays them in the
Driver Information Centre.
9 Warning
The actual traffic sign always
takes priority over the traffic sign displayed in the Driver Information Centre.
If the vehicle enters a road of whichthe entry is prohibited, the no entry
traffic symbol and a warning message are displayed in the Driver
Information Centre. If the system
detects one of the other traffic signs,
the respective traffic sign is displayed
in the Driver Information Centre.
Speed limiter 3 121
Cruise control 3 119
Adaptive cruise control 3 123
Lane keep assist
Lane keep assist supports the driver
to avoid unintended leaving of the
lane. The front camera observes road
edges, as well as the lane markings
between which the vehicle is driving.
If the vehicle approaches a road edge or a lane marking, the steering wheel
is gently turned to position so that the
vehicle turns back into the lane. The
driver will then notice a turning
movement of the steering wheel. Turn steering wheel in same direction, if
the system does not steer sufficiently.
Turn steering wheel gently into
opposite direction, if lane change is
intended.
When the system steers to correct the trajectory of the vehicle, L flashes
yellow in the instrument cluster.
Unintended lane departure is not
assumed by the system when the turn lights are operated and during few
seconds after turn lights have been
switched off.
