automatic function controls heating, air conditioning, blower speed, recirculation, and air distribution. If you select one or more manual functions, the remaining functions continue to be controlled automatically. All manual settings are 83 03 Climate Electronic Climate Control (ECC) switched off when AUTO is switched on. AUTO CLIMATE is shown in the display. 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. 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 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. Timer The timer function minimizes the risk of fogging, or stale air when the recirculation function is selected. See page 73 for information on setting the recirculation timer. NOTE Recirculation is always disengaged if the defroster button is engaged to clear ice or condensation from the side windows. 4. Defroster
