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 via acoustic signals
and display indication.
The system has six ultrasonic parking
sensors in both the rear and front
bumper.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.

The system warns the driver with
acoustic signals against potentially
hazardous obstacles in front of the
vehicle in a distance range up to
80 cm and against potentially
hazardous obstacles behind the
vehicle in a distance range up to
1.5 m.
Depending on which side of the
vehicle is closer to an obstacle, you will hear acoustic warning signals inthe 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 obstacles
is shown in the Driver Information
Centre with Uplevel Display 3 80 or,
depending on the version, on the Colour Info Display 3 85.

Vehicle messages 3 87.Advanced parking assist9 Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
the advanced parking assist.
The advanced parking assist
measures a suitable parking slot
while passing, calculates the
trajectory and automatically steers
the vehicle into a parallel or
perpendicular parking slot.
Instructions are given in the Driver
Information Centre 3 80 or,
depending on the version, on the
Colour Info Display 3 85, supported
by acoustic signals.
The driver must control acceleration,
braking and gearshifting, while
steering is done automatically.
Advanced parking assist can only be activated when driving forwards.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.
1 second) activates or deactivates the
advanced parking assist, see
separate description below.
Driving and operating139for parallel parking slots or 6 m forperpendicular 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 givingthe driver detailed instructions for
braking, accelerating and
gearshifting. 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 in the display show:
● general hints and warning messages
● a hint when driving faster than 18 mph during parking slot
searching mode, or 5 mph 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 gearshift rearwards or forwards
● the demand to accelerate or brake
● for some of the instructions a progress bar is shown in the
Driver Information Centre
● successful parking manoeuvre indicated by a pop-up symbol
and a chime
● the cancelling of a parking manoeuvreDisplay priorities
Advanced parking assist indication on the Driver Information Centre can beinhibited by vehicle messages with ahigher priority. After approving the
message by pressing SET/CLR on
the stalk, advanced parking assist
instructions appear again and the parking manoeuvre can be continued.

● driving faster than 18 mph during
parking slot search
● driving faster than 5 mph during parking guidance
● driver interference on steering wheel detected
● exceeding the maximum number
of gear changes: eight parking
cycles when parallel parking or
five cycles when perpendicular
parking
● switching off the ignition
140Driving and operatingDeactivation by the driver or by the
system during manoeuvring will be indicated by a message in the DriverInformation Centre. 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
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.
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
Driving and operating141gateway, 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
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 an
acoustic signal. 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
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.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 light.
When the system detects a vehicle in the side blind zone while driving
forwards, either while passing a
vehicle or being passed, a yellow
warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn lights,
the warning symbol B starts flashing
yellow as a warning not to change
lanes.
Notice
If the overtaking vehicle is at least
6 mph faster than the vehicle being
overtaken, the warning symbol B in
the relevant exterior mirror may not
illuminate.
