Overview of climate control systems
General notes
Observe the settings recommended on the fol-lowing pages. The windows could otherwisefog up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-tion function
Rswitch on the defrost windshield functionbriefly, if required
Climate control regulates the temperature andthe humidity in the vehicle interior and filtersundesirable substances out of the air.
Climate control can only be operated when theengine is running. Optimum operation is onlyachieved with the side windows and roofclosed.
iWhen the weather is warm, ventilate thevehicle for a brief period. This will speed upthe cooling process and the desired vehicleinterior temperature will be reached morequickly.
iIt is possible that the dehumidificationfunction of the climate control system maybe activated automatically an hour after theSmartKey has been removed. The vehicle isthen ventilated for 30 minutes to dry the air-conditioning system.

DSets climate control to automatic (Ypage 119)

RUse the residual heat function if you want toheat or ventilate the vehicle interior whenthe ignition is switched off. The residualheat function can only be activated or deac-tivated with the ignition switched off.
RVehicles with COMAND:if you change thesettings of the climate control system, theclimate status display appears for three sec-onds at the bottom of the screen in theCOMAND display. You will see the currentsettings of the various climate control func-tions.
ECO start/stop function
During automatic engine switch-off, the cli-mate control system only operates at areduced capacity. If you require full climatecontrol capacity, the ECO start/stop functioncan be deactivated by pressing the ECO but-ton (Ypage 130).

fication on/off
General notes
If you deactivate the "Cooling with air-dehu-midification" function, the air inside the vehiclewill not be cooled. The air inside the vehiclewill also not be dehumidified. The windows canfog up more quickly. Therefore, deactivate thecooling with air-dehumidification function onlybriefly.
The "Cooling with air dehumidification" func-tion is only available when the engine is run-ning. The air inside the vehicle is cooled anddehumidified according to the temperatureselected.
Condensation may drip from the underside ofthe vehicle when it is in cooling mode. This isnormal and not a sign that there is a malfunc-tion.

Setting climate control to automatic
General notes
In automatic mode, the set temperature ismaintained automatically at a constant level.The system automatically regulates the tem-perature of the dispensed air, the airflow andthe air distribution.
The automatic mode functions optimally whenthe "Cooling with air dehumidification" func-tion is activated. If necessary, cooling with airdehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-midification" function, the air inside the vehiclewill not be cooled. The air inside the vehiclewill also not be dehumidified. The windows canfog up more quickly. Therefore, deactivate thecooling with air-dehumidification function onlybriefly.

XSet the desired temperature.
XTo activate:press theXbutton.The indicator lamp in theXbutton lightsup. Automatic air distribution and airflow areactivated.
iWhen automatic mode is enabled, the cli-mate mode can be selected (Ypage 119).

General notes
If you switch on air-recirculation mode, thewindows can fog up more quickly, in particularat low temperatures. Only use air-recirculationmode briefly to prevent the windows from fog-ging up.
Activating/deactivating
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 126).
XTo activate:press therbutton.The indicator lamp in therbutton lightsup.
iAir-recirculation mode is automaticallyactivated at high levels of pollution or athigh outside temperatures. When air-recir-culation mode is activated automatically,the indicator lamp in therbutton is notlit. Outside air is added after about30 minutes.
XTo deactivate:press therbutton.The indicator lamp in therbutton goesout.
iAir-recirculation mode deactivates auto-matically:
Rafter approximately five minutes at out-side temperatures below approximately41 ‡ (5 †)
Rafter approximately five minutes if coolingwith air dehumidification is deactivated
Rafter approximately 30 minutes at outsidetemperatures above approximately 41 ‡(5 †) if the "Cooling with air dehumidifi-cation" function is activated
Switching the residual heat on or off
General notes
The residual heat function is only available onvehicles for Canada.
It is possible to make use of the residual heatof the engine to continue heating the station-ary vehicle for up to 30 minutes after theengine has been switched off. The heatingtime depends on the set interior temperature.
