Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.

General notes
In automatic mode, the set temperature is
maintained automatically at a constant level.

with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,

the rear window defroster switches off auto-
matically after several minutes.
If the battery voltage is too low, the rear win-
dow defroster may switch off.

Rear view camera
General notes
Rear view camera :is in the trunk lid handle.
Rear view camera :is an optical parking and
maneuvering aid. It shows the area behind your vehicle with guide lines in the COMAND
display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
iThe text of messages shown in the
COMAND display depends on the language
setting. The following are examples of rear
view camera messages in the COMAND
display.
Important safety notes
The rear view camera is only an aid. It is not a
replacement for your attention to your imme-
diate surroundings. You are always responsi-
ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there
are no persons, animals or objects in the area
in which you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function in a limited manner:
Rif the tailgate is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent light or LED
lighting (the display may flicker)
Rif there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
Rif the camera lens is dirty or obstructed
Rif the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. license plate holder, bicycle rack).
206Driving systems
Driving and parking

In addition, thermal imaging camera:is
integrated in the radiator grill. The camera
helps detect pedestrians and animals.
Observe the notes on cleaning the thermal
imaging camera and cleaning the windshield
(
Ypage 547).
Important safety notes
Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt
your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not func-
tion if:
Rif there is poor visibility, e.g. due to snow,
rain, fog or spray
Rif the windshield is dirty, fogged up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
Rif the thermal imaging camera in the radia-
tor grill is dirty, fogged up or covered
Ron bends, hilltops or downhill gradients
Rat high outside temperatures
Night View Assist Plus cannot display objects
directly in front of or beside the vehicle. The
actual distance to objects and pedestrians
cannot be gaged accurately by looking at a
screen.
It may be the case that other objects are
marked or highlighted as well as pedestrians
and animals.
Pedestrian and animal recognition
General notes
Pedestrian or animal recognition may be
impaired or inoperative if:
Rpedestrians or animals are partially or
entirely obscured by other objects, e.g.
parked vehicles
Rthe silhouette of the pedestrian or of the
animal in the Night View Assist Plus display
is incomplete or interrupted, e.g. by pow-
erful light reflections
Rpedestrians or animals do not contrast with
the surroundings
Rthe camera system no longer recognizes
pedestrians as persons due to special
clothing or other objects
Rpedestrians are not in an upright position,
e.g. sitting, squatting or lying
Ranimals are not recognized by the system,
e.g. because of their size or shape
Pedestrian and animal recognition is deacti-
vated at temperatures above 90 ‡ (32 †).
The spotlight function and automatic delayed
switch-off are then no longer active.
