Problems with PARKTRONIC
Problem
Possible causes/consequences and
M
MSolutions Only the red segments
in the PARKTRONIC
warning displays are lit.
You also hear a warning
tone for approximately
two seconds.
PARKTRONIC is then
deactivated and the
indicator lamp on the
PARKTRONIC button
lights up. PARKTRONIC has malfunctioned and has been deactivated.
X If problems persist, have PARKTRONIC checked at a qualified
specialist workshop. Only the red segments
in the PARKTRONIC
warning displays are lit.
PARKTRONIC is then
deactivated. The PARKTRONIC sensors are dirty or there is interference.
X Clean the PARKTRONIC sensors (Y page 401).
X Switch the ignition back on. The problem may be caused by an external source of radio or
ultrasound waves.
X See if PARKTRONIC functions in a different location. Active Parking Assist
General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention and brake application
can assist you during parking and when exit-
ing a parking space. You may also use
PARKTRONIC (Y page 236).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or
objects are in the manoeuvring range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. For vehicles with the trailer tow hitch folded
out, the minimum length for parking spaces is
slightly longer.
If you have attached a trailer to your vehicle,
you should not use Active Parking Assist.
Once the electrical connection is established
between your vehicle and the trailer, Active
Parking Assist is no longer available.
PARKTRONIC is deactivated for the rear area. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at a Driving systems

that it is already possible to pull out of the
parking space.

General notes Reversing camera
:is in the boot lid handle.
Reversing camera :is an optical parking
and manoeuvring aid. It shows the area
behind your vehicle with guidelines in the
Audio 20/COMAND Online display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text shown in the Audio 20/COMAND
Online display depends on the language
setting. The following are examples of
reversing camera messages in the
Audio 20/COMAND Online display.
Important safety notes The reversing camera is only an aid. It is not a
substitute for your attention to the immediate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals
or objects in range while manoeuvring and
parking.
Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R if the boot lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker) 244

and stationary objects. If an object (person,
vehicle or other obstacle) is detected, this
object is marked with a bar. Objects located
some distance from the vehicle away are
marked with a yellow bar. If the distance to
the object is very small, the bar is displayed in red.
Object detection only works in full screen
mode.
To ensure that you can use the function, it
must be switched on in Audio 20/COMAND
Online, see the separate operating instruc-
tions. 360° camera (surround view)
General notes The 360° camera is a camera system that
consists of four cameras.
The system evaluates images from the fol-
lowing cameras:
R reversing camera
R front camera
R two cameras in the exterior mirrors
The cameras cover the immediate surround-
ings of the vehicle. The system assists you,
e.g. when parking or at exits with reduced
visibility.
You can show pictures from the 360° camera in full-screen mode or in seven different split-
screen views on the COMAND/Audio 20 dis- play. A split-screen view also includes a top
view of the vehicle. This view is calculated
from the data supplied by the installed cam-
eras (virtual camera).
The seven split-screen views are:
R top view and image from the reversing cam-
era (130° viewing angle)
R top view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
R top view and enlarged rear view Driving systems

R top view and trailer view (vehicles with
trailer tow hitch)
R top view and images from the rear-facing
mirror cameras (rear wheel view)
R top view and images from the forward-
facing mirror cameras (front wheel view)
When the function is active and you shift the
transmission from Dor Rto N, the guidelines
in the COMAND display are hidden.
When you change between transmission
positions Dand R, you see the previously
selected front or rear view.
Important safety notes The 360° camera is only an aid and may show
a distorted view of obstacles, show them
incorrectly or not at all. The 360° camera is
not a substitute for attentive driving.
You are responsible for safe manoeuvring and
parking. Make sure that there are no persons,
animals or objects in range while manoeu-
vring and parking.
You are always responsible for safety, and
must always pay attention to your surround-
ings when parking and manoeuvring. This
applies to the areas behind, in front of and
beside the vehicle. You could otherwise
endanger yourself and others.
The 360° camera will not function or will
function only in a limited manner:
R if the doors are open
R if the exterior mirrors are folded in
R if the boot lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the cameras are exposed to very bright
light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if the camera lenses mist up, e.g. when
driving into a heated garage in winter, caus- ing a rapid change in temperature R
if the camera lenses are dirty or covered
R if the vehicle components in which the
cameras are fitted are damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop.
Do not use the 360° camera in this case. You could otherwise injure others or damage
objects when parking the vehicle.
Guide lines are always shown at road level.
In trailer mode, the guide lines are shown at
the level of the trailer coupling.
The camera in the rear area is protected by
means of a flap. This flap opens when the
360° camera is activated. Observe the notes
on cleaning (Y page 401). For technical rea-
sons, the flap may remain open briefly after
the 360° camera has been deactivated.
Activation conditions The 360° camera image can be displayed if:
R COMAND Online/Audio 20 is switched on,
see the Digital Owner's Manual
R the 360° camera 360° camera function is switched on
i If the 360° camera is activated at speeds
above 30 km/h, a warning message
appears.
The warning message disappears if:
R the vehicle's speed falls below 30 km/h.
The 360° camera is then activated.
R the message is confirmed with the %
