Driving and operating167The adaptive cruise control is
deactivated automatically when:
● The brake pedal is depressed.
● The vehicle accelerates above 180 km/h or slows down below
30 km/h.
● The electric parking brake is applied.
● 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 or theradar system.
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 adaptive cruise control during rain, snow or
heavy dirt, as the radar sensor
can be covered by a water film,
dust, ice or snow. This reduces or suppresses completely the
visibility. In case of sensor
blockage, clean the sensor
cover.
● Do not use the system when the spare wheel is in use.System 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.
● 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.
168Driving and operating● Do not use the adaptive cruisecontrol when towing a trailer.
● Do not use the adaptive cruise control on roads with an incline of
more 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, e.g. 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.
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
Driving and operating1718'' Colour Info Display: Adjust the alert
sensitivity in the settings of the active
safety brake in the vehicle
personalisation 3 106.
The chosen setting will remain until it
is changed. The alert timing will vary
based on vehicle speed. The faster
the vehicle speed, the farther away
the alert will occur. Consider traffic
and weather conditions when
selecting the alert timing.
Deactivation The system can only be deactivated
by deactivating the active emergency braking in the vehicle personalisation
3 106.
System limitations Forward collision alert is designed to
warn on vehicles only, but may react also to other objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● driving on winding or hilly roads
● driving during nighttime● 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
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles, pedestrians
and obstacles directly ahead, when a
collision can no longer be avoided
either by manual braking or by
steering. Before the active
emergency braking applies, the driver is warned by the forward collision
alert 3 169 or the front pedestrian
protection alert 3 174.
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.
Operation conditions
If equipped only with front camera the
active emergency braking operates in
forward gear above walking speed up to 85 km/h. With radar sensor and
front camera active emergency
braking operates in forward gear in
the range between walking speed
and 140 km/h.
Driving and operating1739Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is designed to reduce the vehicle
speed before a collision. It may not
react to animals. After a sudden
lane change, the system needs a
certain time to detect the next
preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the brakes and steer to avoid
collisions.
The system is designed to work with
all occupants wearing their seat belts.
Intelligent brake assist
If the vehicle is equipped with radar
sensor, intelligent brake assist may
be available. Intelligent brake assist
provides a boost to braking when the
brake pedal is quickly applied. The
braking is based on the speed of
approach and distance to a vehicle
ahead.
Minor brake pedal pulsations or pedal movement during this time is normal
and the brake pedal should continue to be applied as needed. Intelligent
brake assist will automatically
disengage only when the brake pedal is released.9 Warning
Intelligent brake assist may
increase vehicle braking in
situations when it may not be
necessary. You could block the
flow of traffic. If this occurs, take
your foot off the brake pedal and
then apply the brakes as needed.
Forward collision alert 3 169.
Front pedestrian protection 3 174.
Deactivation Active emergency braking can be
deactivated in the personalisation
menu 3 106. If deactivated, m
illuminates in the instrument cluster
and a warning message is displayed
in the Driver Information Centre.
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 lamps are not working
System limitations In some cases, the active emergencybraking system may provide an
automatic braking in situations that
186Driving and operating● the vehicle is towing anelectrically connected trailer,
bicycle carrier, etc.
● the vehicle had a rear end accident
● there are extreme temperature changes
Panoramic view system This system allows views of the
vehicle's surroundings to be
displayed as a nearly 360° picture in
the Info Display, like a bird's eye view.
The system uses: ● rear camera, installed in the tailgate
● ultrasonic parking sensors in the rear bumper
● front camera, installed in the front
grill below the enblem
● ultrasonic parking sensors in the front bumper
The screen in the Info Display is
divided into two parts. On the right
there is a view from above the vehicle and on the left there is the view from
the rear or the front displayed. The
parking sensors complete the
information on the view from above
the vehicle.
Activation
The panoramic view system is
activated by:
● engaging a gear or gearbox in a neutral position (front view)
● engaging reverse gear (rear view)
● manual activation in the Info Display when driving not more
than 20 km/h
Functionality
Different views can be selected in the left part of the display. Change the
type of view at any time during a
manoeuvre by pressing the touch
field in the left lower zone of the
display and selecting a view from the
view selection menu:
● Standard view
● Auto mode
● Zoom view
● 180° view
The display is immediately updated
with the type of view selected.
190Driving and operatingFault
In the event of a fault, H appears
in the instrument panel, accompanied
by a display message and a warning
chime. Contact a dealer or a qualified
workshop to have the system
checked.
System limitations The system performance may notoperate properly when:
● Vehicle speed is below 60 km/h.
● Windscreen is not clean or affected by foreign objects, e.g.
stickers
● Driving on winding or hilly roads.
● During nighttime driving.
● Adverse environmental conditions like heavy rain, snow,
direct sunlight or shadows.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,
dirt, windscreen damage or
affected by foreign objects, e.g.
stickers.
● The sun is shining directly into the camera lens.● Close vehicles ahead.
● 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. The driver will then notice a turning
movement of the steering wheel. Turn steering wheel in same direction, if
system 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 notassumed by the system when the turn
lights are operated and during 20 s
after turn lights have been switched off.
Note
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 65 km/h and 180 km/h
● the driver must hold the steering wheel with both hands
● the change of trajectory is not accompanied 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
