Press A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore,
condensation may form and drip from
under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
Driving and operating185● Do not use the system onslippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that the
control of the vehicle can be lost.
● 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.
● The control range is limited to a maximum deviation of 20 mph
between the set speed and the
speed of the vehicle ahead.
● 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 onlyat 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
longer detects any vehicle ahead,
then control indicator I 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
186Driving and operatingthe 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.
Fault
In the event of a fault with the adaptive
cruise control, a warning light is
illuminated and a message is
displayed in the instrument cluster,
accompanied by a warning chime.
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 to avoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera in the windscreen and a radar sensor in the front bumper to
detect a preceding vehicle directly
ahead, in your path.
Driving and operating189FunctionalityActive emergency braking is
equipped with a front camera and
operates in forward gear above
walking speed up to 53 mph. The
system detects stationary vehicles
only if the speed does not exceed
50 mph. Pedestrians are detected
only if the speed does not exceed
37 mph.
A precondition is that active
emergency braking is not deactivated
in the vehicle personalisation menu
3 123.
If deactivated, m illuminates in the
instrument cluster and a warning
message is displayed in the Driver
Information Centre.
If the system has been deactivated, it
is reactivated automatically the next
time the ignition is switched on.
The system includes: ● emergency automatic braking
● forward collision alert
● front pedestrian protectionEmergency 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.
If active emergency braking is
applied, m flashes in the instrument
cluster.
Depending on the situation, the
vehicle may automatically brake
moderately or hard.
Front automatic braking can only
occur if a vehicle or a pedestrian
ahead is detected.
Forward collision alert 3 186
Front pedestrian protection 3 190
Below a speed of 19 mph, emergency automatic braking may slow down thevehicle to a complete stop. If the
speed exceeds 19 mph, emergency
automatic braking reduces the speed.
However, the driver must apply the
brake.Emergency automatic braking may
slow the vehicle to a complete stop to try to avoid a potential crash. If the
vehicle comes to a complete stop,
automatic braking is maintained for
up to 2 seconds.
● Automatic transmission: If the vehicle comes to a complete
stop, keep the brake pedal
depressed to prevent the vehicle
from starting off again.
● Manual transmission: If the vehicle comes to a completestop, 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.
