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.
