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 only
achieved 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.
iThe integrated filter filters out most parti-cles of dust and soot and completely filtersout pollen. It also reduces gaseous pollu-tants and odors. A clogged filter reduces theamount of air supplied to the vehicle inte-rior. For this reason, you should alwaysobserve the interval for replacing the filter,which is specified in the Maintenance Book-let. As it depends on environmental condi-tions, e.g. heavy air pollution, the intervalmay be shorter than stated in the Mainte-nance Booklet.

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.
Activating/deactivating
XTo activate:press theZorVbut-ton.The indicator lamp in theZorVbut-ton lights up.
XTo deactivate:press theZorVbut-ton.The indicator lamp in theZorVbut-ton goes out. The "Cooling with air dehumid-ification" function has a delayed switch-offfeature.

Setting climate control to automatic
General notes
Automatic mode is only available with 3-zoneautomatic climate control.
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.
