04 Comfort and driving pleasure Climate system Auto The function automatically regulates cooling, heating, blower speed, recirculation, and air distribution to maintain the chosen temperature. If you select one or more manual functions, the other functions continue to be controlled automatically. The air quality sensor is engaged and all manual settings are switched off when AUTO is pressed. The display shows AUTO CLIMATE. Blower speed in automatic mode can be set under Climate settings Automatic blower adjust. Choose between Low, Normal or High. Temperature control The temperatures on the driver and passenger sides can be set independently. When the vehicle is started, the most recent setting is resumed. Defroster This function defrosts/de-ices the windshield and front side windows. The indicator light in the defroster button lights when the function is active. NOTE Heating or cooling cannot be speeded up by selecting a higher/lower temperature than the actual temperature required. • Blower speed increases automatically and the air conditioning will switch on (if not already on and if the passenger compartment blower is not turned off) to dehumidify the air in the passenger compartment. Air conditioning can be switched off by pressing the AC button. 04 A/C - ON/OFF The air conditioning is controlled automatically by the system when the ON light is on. This cools/heats and dehumidifies the incoming air. When the OFF light is on, the air conditioning is always disengaged. Other functions are still controlled automatically. When defroster is selected, the air conditioning system is set for maximum blower speed and dehumidification. • Recirculation will not function while defrost is engaged. The climate system will return to its previous settings when the defroster function is switched off. NOTE Selecting the lowest blower speed may increases the risk of fog forming on the windows.
