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 operating1839Warning
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.
Forward looking brake assist
In addition to emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. Therefore, pressing
the brake pedal less strongly results in immediate hard braking. This
function helps the driver brake
quicker and harder before the
imminent collision.
9 Warning
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.
Forward collision alert 3 180.
Front pedestrian protection 3 184.
Deactivation Active emergency braking can be
deactivated in the personalisation
menu 3 119. 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
184Driving and operatingSystem limitations
In some cases, the active emergency braking 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.● Weather limits visibility, such as fog, rain, or snow.
● The windscreen is damaged or affected by foreign items, e.g.
stickers.
Complete attention is always required while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.
Fault
In case the system requires a service, m is illuminated in the instrument
cluster, a message is displayed in the Driver Information Centre and an
audible signal is given.
If the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.
Vehicle messages 3 118.
Front pedestrian protection Front pedestrian protection may helpto avoid or reduce the harm causedby front-end crashes with pedestrians when driving forward.The system uses the front camera in
the windscreen to detect a pedestrian directly ahead in your path.
Front pedestrian protection can
detect and alert to pedestrians in a
forward gear at speeds between
5 km/h and 60 km/h.
During nighttime driving, system
performance is limited.9 Danger
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.
Front pedestrian protection includes:
● detecting front pedestrian ahead● front pedestrian alert
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.
192Driving and operatingDeactivation
The current park assist manoeuvre is
cancelled via the button to return to
the previous screen in the Info
Display. To deactivate the system
completely, press ¼ in the centre
console.
The system is deactivated
automatically:
● if the ignition is switched off
● if stalling the engine
● if no manoeuvre is started within 5 minutes of selection of the typeof manoeuvre
● after a prolonged stop of the vehicle during a manoeuvre
● if the Electronic Stability Control is triggered
● if the speed of the vehicle exceeds the stated limit
● when the driver interrupts movement of the steering wheel
● after seven manoeuvres for entering a perpendicular parking
slot (a manoeuvre consists of
one rear move or one forward
move)● after ten manoeuvres for entering
or exiting a parallel parking slot
● on opening a door or the load compartment
● if one of the front wheels encounters an obstacle
● parking manoeuvre successfully ended
Deactivation by the driver or by the
system during manoeuvring will be indicated on the display. Additionally,
an acoustic signal sounds.
The system is switched off
automatically when towing an
electrically connected trailer, bicycle
carrier, etc.
Contact your dealer to switch off the
system for a prolonged period.
Fault
In the event of a fault, a message is
displayed in the Colour Info Display, accompanied by an acoustic signal.
In the event of a fault in the power
steering, H illuminates and a
message is displayed in the Driver
Information Centre.9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
