03 Climate Electronic Climate Control (ECC)* 2. Blower speed The blower speed can be increased or decreased by turning the knob. The blower speed is regulated automatically if AUTO is selected. The previously set blower speed is disconnected. Timer The timer function minimizes the risk of fogging or stale air when the recirculation function is selected, see page 85 for information on setting the recirculation timer. 5. Airflow controls Press one of the three buttons in the illustration to activate the selected airflow. A symbol in the display above the climate control panel and a lit LED in the selected button indicate that the manual function has been selected. With manually selected airflow both warm and cool air can be selected. See also the table on page 102. NOTE Recirculation is always disengaged if the defroster button is engaged to clear ice or condensation from the side windows. 03 NOTE If the knob is turned counterclockwise and the blower indication in the display goes out, the blower and the air conditioning are switched off. The display shows the blower symbol and OFF. 4. Defroster Directs airflow to the windshield and side windows and increases blower speed. When the defroster is activated: 6. Air conditioning On/Off ON: The air conditioning system is engaged when the ON light is lit and is controlled automatically by the system to maintain the selected temperature. OFF: The system is disengaged when the OFF lights up When OFF is selected and the OFF LED is lit, the air conditioning system is deactivated. Other functions are still controlled automatically. When Defroster (4) is selected, the air conditioning system is activated for maximum dehumidifying. 3. Recirculation This function can be used to shut out exhaust fumes, smoke, etc from the passenger compartment. The air in the passenger compartment is then recirculated, i.e. no air from outside the car is taken into the car when this function is activated. If the air in the car recirculates for too long, there is a risk of condensation forming on the insides of the windows, especially in winter. • Air flows to the windows at high blower speed. • The LED in the defroster button lights up when this function is activated. The air conditioning system is controlled to provide maximum air dehumidification. • The air conditioning is automatically switched on (can be switched off by pressing button 6). The air is not recirculated. `` * Option/accessory, for more information, see Introduction. 101
