Deactivation
The system automatically switches
off when reverse gear is disengaged.
Manual deactivation is also possible
by pressing the parking assist button
r .
In both cases, the LED in the button
extinguishes.
Fault
In the event of a fault or if the system does not work temporarily, e.g.
because of high external noise level
or other interference factors, the LED
in the button flashes for
three seconds and then extinguishes.
Control indicator r illuminates in
the instrument cluster 3 92 or a
message is indicated in the Driver Information Centre.
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 and
behind the vehicle. It informs and
warns the driver by giving acoustic
signals and display indication.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.
The system has four ultrasonic
parking sensors each in the rear and front bumper.
If the vehicle is equipped with
advanced parking assist, the system
has six ultrasonic parking sensors
each in both the rear and front
bumper.
Page 162 of 261

160Driving and operating
Advanced parking assist is always
combined with front-rear parking assist, see previous section. Both
systems use the same sensors in the front and rear bumper.
Button D and operation logic
Advanced parking assist and front-
rear parking assist both use the same
button for activation and deactivation:
A brief press of D activates or
deactivates the parking assist.
A long press of D (approx.
one second) activates or deactivates
the advanced parking assist, see
separate description below.
Button logic operates the systems by
pressing D as follows:
■ If only front-rear parking assist is active, a brief press deactivates
front-rear parking assist.
■ If only front-rear parking assist is active, a long press activates
advanced parking assist.
■ If only advanced parking assist is active and the system is in parking
slot searching mode, a brief press
activates front-rear parking assist.
■ If only advanced parking assist is active and the system is in park
guiding mode, a brief press
deactivates advanced parking
assist.
■ If only advanced parking assist is active, a long press deactivates
advanced parking assist.
■ If forward gear or neutral is selected, a brief press activates ordeactivates only front parking
assist.
■ If reverse gear is selected, a brief press activates or deactivates frontand rear parking assist.Activation
When searching for a parking slot, the
system is ready to operate with a long press of D.
The system recognises and
memorises (10 metres for parallel
parking slots or six metres for
perpendicular parking slots) even in
the parking assist mode. A long press
of D activates advanced parking
assist to start parking manoeuvre.
The system can only be activated at
a speed up to 18 mph and the system searches for a parking slot at a speed
up to 18 mph.

■ The successful completion of theparking manoeuvre indicated by a
pop-up symbol and a chime.
■ The cancelling of a parking manoeuvre.
Display priorities
Advanced parking assist indication in the DIC can be inhibited by vehicle
messages with a higher priority. After
approving the message by pressing
SET/CLR on the turn signal lever,
advanced parking assist instructions
appear again and the parking
manoeuvre can be continued.
Deactivation
The system is deactivated by:
■ a long press of D
■ parking manoeuvre successfully ended
■ driving faster than 18 mph during parking slot search
■ driving faster than 5 mph during parking guidance
■ driver interference on steering wheel detected■ exceeding number of maximumgear changes: eight cycles when
parallel parking or five cycles when
perpendicular parking
■ switching off the ignition
Deactivation by the driver or by the system during manoeuvring will beindicated by Parking Deactivated on
the display. Additionally, an acoustic
signal sounds.
Fault
A message appears when:
■ There is a fault in the system.
■ The driver did not successfully complete the parking manoeuvre.
■ The system is not operational.
■ Any of the deactivation reasons described above apply.
If an object is detected during parking
instructions, Stop is indicated on the
display. Removing the object will
resume the parking manoeuvre. If the
object is not removed, the system will
be deactivated. A long press of D
will activate the system and search for a new parking slot.Basic notes on parking assist
systems9 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
Page 166 of 261

164Driving and operatingcorrect 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.
Notice
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.
Notice
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 at first, the
parking assist will detect the rear
carrier system and provide a buzzing
sound. Press r or D briefly to
deactivate the parking assist.
Notice
After production, the system
requires a calibration. For optimal
parking guidance, a driving distance
of at least 6 miles, 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.
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.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.

166Driving and operating9Warning
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 between the
number plate lights and has a viewing angle of 130°.
The 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.
Display settings
Brightness and contrast can be set by
tapping the touch screen display
when rear view camera is active.
