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. • If the green indicator light to the left is on, recirculation is on and no outside air flows into the passenger compartment. Interior Air Quality System (IAQS)* This system consists of a multifilter that helps reduce gases and particles in the incoming air and an air quality sensor that detects increased levels of contaminants in the outside air. When the air quality sensor detects contaminated outside air, the air intake closes and the air inside the passenger compartment is recirculated. The filter also cleans recirculated passenger compartment air. When IAQS is engaged, the green indicator light above A is illuminated. To activate IAQS: - Or: Toggle between the system's three modes by pressing the button the recirculation button repeatedly. Press AUTO (1). • If the green indicator light to the right is on, outside air flows into the passenger compartment. While the indicator light on the right side is on, the ECC system automatically controls the flow of air into the passenger compartment and the air intake is opened or closed depending on the outside temperature, the need to heat or cool the compartment, etc. 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. 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. 3. Recirculation This function is used to recirculate the air in the passenger compartment, which means that when the function is active, no outside air enters the compartment. This is particularly useful in hot or cold weather to cool or heat the passenger compartment faster, or to help shut out exhaust fumes, etc. Press the button repeatedly to close out outside air (recirculation) or to let outside air flow into the passenger compartment. Recirculation timer The timer function minimizes the risk of fogging or stale air when the recirculation function is selected, see page 84 for information on setting the recirculation timer. NOTE If the defroster function is switched on (by pressing button 4), recirculation is always disengaged. • The green indicator light above A is on: IAQS is engaged. Outside air flows into the passenger compartment and is filtered. While this light is on, the ECC system automatically controls the flow of air into the passenger compartment and the air intake is opened or closed depending on the outside temperature, the need to heat or cool * Option/accessory, for more information, see Introduction. 99
