Driving and operating193The feature uses various inputs (e.g.
radar sensor, brake pressure, vehicle
speed) to calculate the probability of
a frontal collision.
Active emergency braking operates
automatically above walking speed,
provided that Auto collision
preparation setting is not deactivated
in the vehicle personalisation menu
3 129.
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist9Warning
This system is not intended to
replace the driver responsibility of driving the vehicle and looking
ahead. Its function is limited to
supplemental use only. The driver shall continue to apply the brake
pedal as the driving situation
dictates.
Brake preparation system
When approaching a vehicle ahead
so quickly that a collision is likely, the
brake preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that braking can occur more rapidly.
Emergency automatic braking
After the brake preparation and just
before the imminent collision, this
function automatically applies limited
braking to reduce the impact speed of the collision.
Forward looking brake assist
In addition to brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. In this way,
depressing the brake pedal slightly
results immediately in a strong
braking. This function helps the driver
brake quicker and stronger before the imminent collision.9 Warning
Active emergency braking is not
designed to apply strong
autonomous braking or to avoid automatically a collision. It is
designed to reduce the vehicle
speed before collision. It may not
react on stopped vehicles,
pedestrians or 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 shall 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.
System limitations
The active emergency braking has
limited or no function during rain,
snow or heavy dirt, as the radar
sensor can be covered by a water
194Driving and operatingfilm, dust, ice or snow. In case of
sensor blockage, clean the sensor
cover.
In some seldom cases the active
emergency braking system may
provide a short automatic braking in
situations that seem to be
unnecessary, for instance due to
traffic signs in a curve or due to
vehicles in another lane. This is
acceptable operation, the vehicle
does not need service. Firmly apply
the accelerator pedal to override the automatic braking.
Settings Settings can be changed in the Auto
collision preparation menu in the
vehicle personalisation, 3 129.
Fault
In the event of a system service
requirement, a message is displayed
in the Driver Information Centre.
If the system does not work as it
should, vehicle messages are
displayed in the Driver Information
Centre.

Parking assist
Front-rear parking assist9 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.
The front-rear parking assist
measures the distance between the vehicle and obstacles in front of and
behind the vehicle. The system gives acoustic signals and display
messages.
Driving and operating201Note
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
It is possible that the sensor detects
a non-existing object (echo
disturbance) caused by external
acoustical or mechanic
disturbances.
Advanced parking assist system
may not respond to changes in the
parking space after initiating a
parallel parking manoeuvre.
Note
If engaging a forward gear and
exceeding a certain speed, the rear
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse gear first, the
parking assist will detect the rear
carrier system and provide a buzzing sound. Press D briefly to
deactivate the parking assist.Note
After production, the advanced
parking assist requires a calibration.
For optimal parking guidance, a
driving distance of at least 35 km,
including a number of bends, is
required.
Side blind spot alert
The side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system alerts visually in each exterior mirror, when
detecting objects that may not be
visible in the interior and exterior
mirrors.
The system's sensors are located in
the bumper on the left and right side
of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
● vehicles outside the side blind zones which may be rapidly
approaching
● pedestrians, cyclists or animals
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects a vehicle in the side blind zone while driving
forward, either while passing a
vehicle or being passed, an amber
warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol B starts flashing
amber as a warning not to change
lanes.
Note
If the passing vehicle is at least
10 km/h faster than the passed
vehicle, the warning symbol B in the
relevant exterior mirror may not
illuminate.
Driving and operating2039Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
advanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.
Do not reverse the vehicle by only looking at the Info-Display and
check the surrounding area
behind and around the vehicle
before reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted in the tailgate handle and has a viewing angle of
130°.
Due to the high position of the
camera, the rear bumper can be seen on the display as a guide to position.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Guiding lines
Dynamic guiding lines are horizontal
lines in one metre intervals projected
on the picture to define the distance
to shown objects.
Trajectory lane of the vehicle is
shown in accordance with the
steering angle.
Driving and operating207Once the Settings page is displayed,
select Off to deactivate pop-up
function. Reactivate by selecting On.
When switching on the ignition, pop-
up function is deactivated.
Pop-up indication is displayed for
approx. eight seconds in the Driver
Information Centre.
Fault The traffic sign assistant system may
not operate correctly when:
● The area of the windscreen, where the front camera is
located, is not clean.
● Traffic signs are completely or partially covered or difficult to
discern.
● There are adverse environmental
conditions, e.g. heavy rain, snow,direct sunlight or shadows. In this
event No Traffic Sign Detection
due to Weather is indicated in the
Driver Information Centre.● Traffic signs are incorrectly mounted or damaged.
● Traffic signs do not comply with the Vienna Convention on trafficsigns (Wiener Übereinkommen
über Straßenverkehrszeichen).Caution
The system is intended to help the driver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
● No operation of turn signals.
● No brake pedal operation.
● No active accelerator operation or speeding-up.
● No active steering.
If the driver is active, no warning will
be issued.
