The pollutant-sensitive air-recirculation mode automatically switches off the supply of outside air when pollutants are detected in the air. Air conditioning The cooling function, only operational when the engine is running, cools the vehicle interior down to the selected temperature. The cooling function also dehumidifies the air in the vehicle interior, thus preventing the windows from fogging up. i The pollutant-sensitive air-recirculation mode is not possible if you have switched off the air conditioning or if the temperature falls below 41°F (5°C). i Condensation may drip out from underneath the vehicle. This is normal and not an indication of a malfunction. Warning! G If you turn off the cooling function, the vehicle will not be cooled when weather conditions are warm. The windows can fog up more quickly. Window fogging may impair visibility and endanger you and others. 233
