Driving and operating177Indication
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
50 cm while a forward gear is
engaged, or up to 1.5 m while reverse
gear is engaged.
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
Information Centre 3 83 or,
depending on the version, on the Info display 3 86.
The distance indication can be
inhibited by vehicle messages with a higher priority. After dismissing themessage distance indication appears again.
Deactivation
The system is deactivated
automatically when vehicle speed
exceeds 11 km/h.
Manual deactivation is also possible
by pressing the parking assist button
r .
When the system is deactivated
manually, the LED in the button
extinguishes and Park Assist off
pops-up in the Driver Information
Centre.
After a manual deactivation, the front- rear parking assist is activated again
if r is pressed or if reverse gear is
engaged.
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, a
message pops-up in the Driver
Information Centre.

178Driving and operatingAdvanced parking assist9Warning
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 83 or,
depending on the version, on the Info display 3 86, supported by acoustic
signals.
The driver must control acceleration, braking and gearshifting, while
steering is done automatically.Advanced parking assist is always
combined with front-rear parking assist. Both systems use the same
sensors in the front and rear bumper.
The system has six ultrasonic parking
sensors in the front bumper and five
ultrasonic parking sensors in the rear
bumper.
Activation of advanced parking assist Advanced parking assist can only be
activated when driving forwards.When searching for a parking slot, the system is ready to operate with a
short press of (.
The system recognises and
memorises ten metres for parallel
parking slots or six metres for
perpendicular parking slots in the parking assist mode.
The system can only be activated at
a speed up to 30 km/h and the system
searches for a parking slot at a speed up to 30 km/h.
The maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres for parallel parking and 2.5 metres for
perpendicular parking.
Driving and operating179FunctionalityParking slot searching mode,
indication in the Info display
Select parallel or perpendicular
parking slot by touching the
respective icon on the display.
Select parking side by touching the
respective icon on the display.
When a slot is detected, a visual
feedback on the 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
ten 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
180Driving and operatingbraking, 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.
● 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.● The demand to stop or to driveslowly.
● For some of the instructions a progress bar is shown in the
Driver Information Centre.
● The successful completion of the
parking manoeuvre indicated by
a pop-up symbol and a chime.
● The cancelling of a parking manoeuvre.
Display priorities
Advanced parking assist indication in
the Info display can be inhibited by
vehicle messages with a higher
priority. After approving the message, advanced parking assist instructions
appear again and the parking
manoeuvre can be continued.
Deactivation
The system is deactivated by:
● a short press of (
● parking manoeuvre successfully ended
● driving faster than 30 km/h during
parking slot search● driving faster than 8 km/h during parking guidance
● driver interference on steering wheel detected
● exceeding number of maximum gear changes: eight cycles when
parallel parking or five cycles
when perpendicular parking
● switching off the vehicle
Deactivation by the driver or by the
system during manoeuvring will be indicated by a message 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
Driving and operating181object is not removed, the system will
be deactivated. A long press of ( 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.
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
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
182Driving and operatingmirror, when detecting objects that
may not be visible in the interior and
exterior mirrors.
The radar distance sensors are
located in the rear bumper.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
forwards, either while passing a
vehicle or being passed, a yellow
warning symbol F will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol F starts
flashing yellow as a warning not to
change lanes.
When the vehicle is started, both
exterior mirror displays will briefly illuminate to indicate that the system
is operating.
The system can be activated or
deactivated in the Info display.
Vehicle personalisation 3 92.
Deactivation is indicated by a
message in the Driver Information
Centre.
Detection zones
The detection zones start at the rear
bumper and extend approx.
three metres rearwards and to the
sides. The height of the zone is
approx. between half a metre and
two metres off the ground.
Side blind spot alert is designed to ignore stationary objects, e.g.
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Fault
Occasional missed alerts can occur
under normal circumstances and will
increase in wet conditions.
Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice, slush, or in heavy
rainstorms. Cleaning instructions

In the event of a fault in the system or if the system does not work due to
temporary conditions, the symbols in
the mirrors will be permanently
Driving and operating183illuminated and a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.
Lane change alert Additional to the side blind spot alert
3 181, lane change alert recognises
rapidly approaching vehicles from
behind on parallel lanes next to your
vehicle.
If the vehicle is equipped with lane
change alert, side blind spot alert is
always included.
The system alerts visually in each
exterior mirror when detecting rapidly
approaching vehicles from behind.
The radar distance sensors are
located in the rear bumper.9 Warning
Lane change alert does not
replace driver vision.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects an
approaching vehicle from behind
which drives considerably faster, the
yellow warning symbol F will
illuminate in the relevant exterior mirror. If the driver then activates the
turn signal, the warning symbol F
starts flashing yellow as a warning not to change lanes.
Lane change alert is active at all
speeds.
When the vehicle is started, both
exterior mirror displays will briefly come on to indicate that the system is operating.
Detection zones
The system sensors cover a zone of
approx. 3.5 metres parallel on both
vehicle sides and approx.
three metres rearwards on side blind
zone alert (A) and approx. 70 metres
rearwards on lane change alert (B) on
parallel lanes. The zones start at each exterior mirror. The height of the zone
is approx. between 0.5 metres and
two metres off the ground.
Deactivation Activation or deactivation of the lanechange alert can be set in the vehicle personalisation menu in the Info
display.

Deactivation is indicated by a message in the Driver Information
Centre.
Note
After production, the system
requires a calibration. For optimal
performance, drive as soon as
possible on a straight highway road
with roadside objects, e.g. guardrails
and barriers for some distance.
System limitations
Occasional missed alerts can occur
under normal circumstances or in
sharp curves. The system can
temporarily alert of objects in the blind spot at specific weather conditions
(rain, hail etc). Driving on a wet road
or in the transitions from a dry area to a wet area can cause the system to
light up, as water splash can be
interpreted as an object. Otherwise
F may illuminate due to guardrails,
signs, trees, shrubs or other immobile objects. This is normal operation and
the system does not need a service.The system may not operate properly
when:
● ice, snow, mud, or anything else covers the sensors
● driving in heavy rainstorms
● the vehicle had an accident
● there are extreme temperature changes
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.
Panoramic view system
The panoramic view system vision
displays an image of the area
surrounding the vehicle, along with
the front or rear camera views in the
centre console.The system uses four cameras:
● rear camera, installed above the license plate
● front camera, installed in the grille or near the front emblem
● side cameras, located at the bottom of both exterior mirrors.9Warning
The surround vision cameras have
blind spots and will not display all
objects near the corners of the
vehicle. Folding side mirrors that
are out of position will not display
the surrounding view correctly.
Always check around the vehicle
when parking or reversing.
