Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
1.5 metres and in front up to 80 cm.
Depending on which side of the
vehicle is closer to an obstacle, you
will hear acoustic warning signals in
the vehicle on the respective side.
The interval between the sounds
becomes shorter as the vehicle gets closer to that obstacle. When the
distance is less than approx. 30 cm, the sound is continuous.
Additionally, the distance to rear and
front obstacles is displayed by
changing distance lines in the Driver

166Driving and operatingInformation Centre 3 97 or,
depending on the version, on the
Colour-Info-Display 3 101.
The distance to rear and front
obstacles is displayed by changing
distance lines in the Driver
Information Centre 3 97.
The distance indication can be
inhibited by vehicle messages with a higher priority. After approving the
message by pressing SET/CLR on
the turn signal lever, distance
indication appears again.
The distance to obstacles is shown on the Colour-Info-Display by coloured

168Driving and operating
Select parallel or perpendicular
parking slot by tapping the respective icon on the display.
Select parking side by tapping the
respective icon on the display.
When a slot is detected, a visual
feedback on the Colour-Info-Display
and an acoustic signal is given.
If the driver does not stop the vehicle after a parking slot is proposed, the
system starts to search for another
suitable parking slot.Park guiding mode
The parking slot suggestion of the system is accepted when the vehicle
is stopped by the driver within
10 metres for parallel parking slots or
six metres for perpendicular parking
slots after the Stop message is given.
The system calculates the optimal
path into the parking slot.
A brief vibration in the steering wheel
after engaging reverse gear indicates
that the steering is controlled by the
system. Then the vehicle is steered into the slot automatically by giving
the driver detailed instructions for
braking, accelerating and gear
shifting. The driver must keep hands
away from the steering wheel.Always pay attention to the sound of
the front-rear parking assist.
Continuous sound indicates that the
distance to an obstacle is less than
approx. 30 cm.
If, for any reason, the driver must take over control of the steering, hold the
steering wheel only at the outer edge. Automatic steering is cancelled in thisevent.Display indication
The instructions on the display show:
● General hints and warning messages.
● A hint when driving faster than 30 km/h during parking slot
searching mode, or 8 km/h in
guiding mode.
● The demand to stop the vehicle, when a parking slot is detected.
● The direction of driving during the
parking manoeuvre.
● The demand to shift into reverse or first gear.

170Driving and operatingCaution
Performance of the system can bereduced 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.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Note
It is possible that the sensor detects a non-existing object caused by
echo disturbance from external
acoustic noise or mechanical
misalignments (sporadic false
warnings may occur).
Make sure that the front number
plate is properly mounted (not bent
and no gaps to the bumper on the left
or right side) and the sensors are
firmly in place.
Advanced parking assist system
may not respond to changes in the
available parking space after
initiating a parking manoeuvre. The
system may recognize an entry, a
gateway, a courtyard or even a crossing as a parking slot. After
selecting reverse gear the system
will start a parking manoeuvre. Take care regarding the availability of the
suggested parking slot.
Surface irregularities, e.g. on construction zones, are not detected
by the system. The driver accepts
responsibility.
Note
If engaging a forward gear and
exceeding a certain speed, the
parking assist will be deactivated
when the rear carrier system is
extended.If engaging reverse for the first time,
the parking assist will detect the rear carrier system and provide a buzzing
sound. Press r or D briefly to
deactivate the parking assist.
Note
After production, the system
requires a calibration. For optimal
parking guidance, a driving distance
of at least 10 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
displays a visual alert in each exterior
mirror, when detecting objects that
may not be visible in the interior and
exterior mirrors.
Side blind spot alert uses some of the advanced parking assist sensors
which are located in the front and rear
bumper on both sides of the vehicle.

Driving and operating173The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Warning symbols
Warning symbols are indicated as
triangles 9 on the picture, which show
obstacles detected by the rear
sensors of the advanced parking
assist.
Additionally 9 appears on the top line
of the Info-Display with the warning to
check the vehicle surrounding.
Deactivation
The camera is deactivated when a certain forward speed is exceeded or
if reverse gear is not engaged for
approx. ten seconds.
Rear view camera can be manually deactivated in the vehicle
personalisation menu in the
Info-Display. Vehicle personalisation

warning symbols
Activation or deactivation of the visual guiding lines and the warning
symbols can be changed by touch
buttons in the lower zone of the
display.
Fault
Fault messages are displayed with a
9 on the top line of the Info-Display.
The rear view camera may not
operate properly when:
● The surrounding is dark.
● The sun or the beam of headlights is shining directly into
the camera lens.
● Ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth.
● The vehicle is towing a trailer.
● The vehicle had a rear end accident.
● There are extreme temperature changes.Traffic sign assistant
Functionality
The traffic sign assistant system
detects designated traffic signs via a
front camera and displays them in the Driver Information Centre.
Traffic signs, which will be detected,
are:
Limit and no passing signs ● speed limit
● no passing
● end of speed limit
● end of no passing

176Driving and operatingIn some cases, traffic sign assistant is
cleared up automatically by the
system.
Clearing of traffic signs
There are different scenarios that
lead to clearing the currently
displayed traffic signs. After clearing,
the “Default Sign” is displayed in the
Driver Information Centre.
Reasons for signs being cleared: ● A predefined distance was driven
or time has elapsed (differs for
each sign type)
● Vehicle drives through a turn
● The speed becomes slower than 52 km/h (city entry detection)
Fault
The traffic sign assistant system may
not operate correctly if:
● The area of the windscreen, where the front camera is
located, is not clean or affected
by foreign items, e.g. stickers.
● 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.
● Traffic signs are incorrectly mounted or damaged.
● Traffic signs do not comply with the Vienna Convention on traffic
signs (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 performing these
actions, no warning will be issued.
