Side windows
Important safety notes
GWARNING
While opening the side windows, body parts
could become trapped between the side win-
dow and the door frame as the side window
moves. There is a risk of injury.
Make sure that nobody touches the side win-
dow during the opening procedure. If some-
body becomes trapped, release the switch or pull the switch to close the side window again.
GWARNING
While closing the side windows, body parts inthe closing area could become trapped. There is a risk of injury.
When closing make sure that no parts of the
body are in the closing area. If somebody
becomes trapped, release the switch or pressthe switch to open the side window again.
GWARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
Activate the override feature for the rear side
windows. When leaving the vehicle, always
take the SmartKey with you and lock the vehi-
cle. Never leave children unsupervised in thevehicle.
Side window reversing feature
The side windows are equipped with an auto- matic reversing feature. If a solid object
blocks or restricts a side window from trav-
eling upwards during the automatic closing
process, the side window opens again auto-
matically. During the manual closing process,
the side window only opens again automati-
cally after the corresponding switch is
released. The automatic reversing feature is
only an aid and is no substitute for your atten- tion when closing a side window.
GWARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R while resetting
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.

cle interior temperature: set airflow con-
trol Ato a setting between 1and 3
( Y page 127).
R Recommendation for air distribution in
winter: select the Oand¯ settings
( Y page 127).

Overview of climate control systems121
Climate cont rol

RUse the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual
heat function can only be activated or deac- tivated with the ignition switched off.
R If you change the settings of the climate
control system, the climate status display
appears for approximately three seconds
at the bottom of the screen in the Audio/
COMAND display (see separate operating
instructions). You will see the current set-
tings of the various climate control func-tions.
ECO start/stop function
During automatic engine switch-off, the cli-

Activating/deactivating cooling with
air dehumidification
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, only
deactivate the "Cooling with air-dehumidifi-
cation" function 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 temperatureselected.
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
The automatic function is only available in
conjunction with dual-zone automatic climate
control.
In automatic mode, the set temperature is
maintained automatically at a constant level. The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
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-

Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windshield
and the hood free of blockages, such as ice,
snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.
iYou can move the adjusters for the air
vents vertically or horizontally to set the
direction of the airflow.
iFor optimal climate control in the vehicle,
open the air vents completely and set the
adjusters to the central position.
