178Driving and operating● The electric parking brake isapplied.
● The Traction Control system or Electronic Stability Control is
deactivated or operating.
● The selector lever of automatic transmissions is neither in D nor
in M.
● A fault is detected in the Electronic Stability Control.
Switching off the system
Press C, the adaptive cruise control
mode is disabled and the adaptive
cruise control indication extinguishes
in the Driver Information Centre.
Pressing ß to activate the speed
limiter deactivates adaptive cruise
control.
Switching off the ignition deletes the
stored set speed.
Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it
again.● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control of the vehicle.
● Do not use the system when the spare wheel is in use.
System limits9 Warning
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.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles only
at low speed.
● Do not use the adaptive cruise control when towing a trailer.
● Do not use the adaptive cruise control on roads with an incline ofmore than 10%.
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
Driving and operating179longer 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.
Motorways
On motorways, adapt the set speed
to the situation and the weather.
Always consider that adaptive cruise
control has a limited visibility range, a
limited braking level and a certain
reaction time to verify if a vehicle is on
the driving path or not. Adaptive
cruise control may not be able to
brake the vehicle in time to avoid a
collision with a much slower vehicle or after a lane change. This is
particularly true while driving fast or if the visibility is reduced due to weather
conditions.
While entering or exiting a motorway,
adaptive cruise control may lose the
vehicle ahead and accelerate up to
the set speed. For this reason,
decrease the set speed before the
exit or before the entry.
Vehicle path changes
If 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.
180Driving 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 between 5 km/h and 85 km/h. The system detects
stationary vehicles if the speed does
not exceed 80 km/h.
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 operating185Front pedestrian protection is
activated together with forward
collision alert.
Forward collision alert 3 180.
Detecting front pedestrian ahead
A pedestrian ahead up to a distance
of approximately 40 m is indicated by
a symbol in the instrument cluster.
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
5 km/h to 60 km/h in forward gear
● the distance to an pedestrian ahead is more than 40 m
● driving on winding or hilly roads
● driving during nighttime
● weather limits visibility, such as fog, rain, or snow
● the sensor in the windscreen is blocked by snow, ice, slush, mud,dirt etc.
● the windscreen is damaged or affected by foreign objects, e.g.
stickers
Parking 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 rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals
and display indication.
The system operates with ultrasonic
parking sensors in the rear bumper.
Activation
Rear parking assist is activated when reverse gear is engaged and ignition
is switched on. This is confirmed by
an accoustic chime.
