dow defroster may switch off.

0050Solutions The rear window
defroster has deactiva-
ted prematurely or can-
not be activated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.
The operation of air-recirculation mode is the same for all control panels.
Activating/deactivating X
Turn the SmartKey to position 2in the igni-
tion lock (Y page 143).
X To activate: press the008Abutton.
The indicator lamp in the 008Abutton lights
up.
i Air-recirculation mode is activated auto-
matically at high outside temperatures.
When air-recirculation mode is activated
automatically, the indicator lamp in the
008A button is not lit. Outside air is added
after about 30 minutes.
X To deactivate: press the008Abutton.
The indicator lamp in the 008Abutton goes

Air-recirculation mode deactivates auto-
matically:
R after approximately five minutes at out-
side temperatures below approximately
41 ‡ (5 †)
R after approximately five minutes if the
"Cooling with air dehumidification" func-
tion is deactivated
R after approximately 30 minutes at out-
side temperatures above approximately
41 ‡ (5 †) if the "Cooling with air dehu-
midification" function is activated Activating/deactivating the residual
heat function
General notes The residual heat function is only available in
vehicles for Canada with dual-zone automatic
climate control.
It is possible to make use of the residual heat
of the engine to continue heating the vehicle
for approximately 30 minutes after the engine
has been switched off. The heating time
depends on the set interior temperature.
i The blower will run at a low speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed. Operating the climate control systems

Rear view camera
General notes Rear view camera
0043is in the handle on the
tailgate.
The rear view camera is an optical parking and maneuvering aid. It uses guide lines to show
the area behind your vehicle in the Audio/
COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
The rear view camera is protected from rain-
drops and dust by means of a flap. When the
rear view camera is activated, this flap opens. Only once the maneuvering process has been
completed and the rear view camera has
switched off does the flap close again. For
technical reasons, the flap may remain open
briefly after the rear view camera has been
deactivated. If you switch off the engine, the
flap will also close.
i The 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.
Observe the notes on cleaning (Y page 302).
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:
R the tailgate 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 light or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if 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).
Activating/deactivating the rear view
camera X
To activate: make sure that the SmartKey
is in position 2in the ignition lock.
X Make sure that the "Activation by R gear"
function is selected in the Audio system/
COMAND; see the separate operating
instructions.
X Engage reverse gear.
Guide lines are used to show the area
behind the vehicle in the Audio/COMAND
display.
To deactivate: the rear view camera deacti-
vates if you shift the transmission to Pon
vehicles with automatic transmission or after driving forwards a short distance. 194
Driving systemsDriving and parking

Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else cover-
ing the sensors
R there is poor visibility, e.g. due to fog, heavy
rain or snow
R a narrow vehicle traveling in front, e.g. a
motorbike or bicycle
R the road has very wide lanes
R the road has narrow lanes
R you are not driving in the middle of the lane
R there are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated. Blind Spot Assist monitors the area up to 10 ft
(3.0 m) behind your vehicle and directly next
to your vehicle, as shown in the diagram. For
this purpose, Blind Spot Assist uses radar
sensors in the rear bumper.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may be the case if the vehicles are driving on the inner
side of their lane. Due to the nature of the system:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free of dirt, ice
or slush in the vicinity of the sensors. For
example, the radar sensors must not be cov-
ered by bicycle racks or overhanging loads.
Following a severe impact or in the event of
damage to the bumpers, have the function of
the radar sensors checked at a qualified spe-
cialist workshop. Blind Spot Assist may oth-
erwise not work properly.
Indicator and warning display
Blind Spot Assist is not active at speeds below approximately 20 mph (30 km/h). Vehicles in the monitoring range are then not indicated. 0043
Yellow indicator lamp/red warning lamp
When Blind Spot Assist is activated, indicator
lamp 0043in the exterior mirrors lights up yel-
low at speeds of up to 20 mph (30 km/h). At speeds above 20 mph (30 km/h), the indica-
tor lamp goes out and Blind Spot Assist is
operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
20 mph (30 km/h), then warning lamp 0043on
the corresponding side lights up red. This
warning is always emitted when a vehicle Driving systems
