6. Turn the controller to adjust the air distribution. At the lowest temperature, the automatic climate control switches into recirculating air mode. The maximum air volume flows out of the vents for the upper body. Therefore, open these vents for maximum cooling. Driver's side: 1 2 3 4 5 Air directed toward the windshield and side windows Air for the upper body Air to footwell Air for the upper body Air to footwell Pressing the AUTO button cancels the manual air distribution settings.< The automatic mode for the air volume remains effective with manual air distribution. Front passenger side: By pressing the button repeatedly, you can request three operating modes: > LED off: outside air flows in continuously. > Right LED on, AUC mode: the system detects pollutants in the outside air and shuts off the supply as needed. > Left LED on, recirculated-air mode: the supply of outside air is permanently shut off. Should the windows fog up in the recirculated-air mode, press the AUTO button or switch off the recirculated-air mode and increase the air volume if necessary. The recirculated-air mode should not be used over an extended period of time, as the air quality inside the vehicle deteriorates continuously.< Switching cooling function on and off The cooling function cools and dehumidifies the incoming air before also reheating it as required, according to the temperature setting. This function is only available when the engine is running. The cooling function helps to avoid condensation on the window surfaces or to quickly remove them. Depending on the weather, the windshield may fog over briefly when the engine is started. The cooling function is also switched on with the AUTO program. Residual heat The heat stored in the engine is used to heat the passenger compartment, e.g. while stopped at a school to pick up a child. 1. Switch off the engine. The function can be switched on when the following conditions are met: > up to 15 minutes after switching off the engine > with engine at operating temperature 117 2. Turn to the right, refer to arrow. Maximum cooling Maximally cooled air is obtained as quickly as possible at an outside temperature above approx. 327/ 06 and with the engine running.

The system then recirculates the air currently within the vehicle. During AUC operation, a sensor detects pollutants in the outside air and controls the shut-off automatically.
