The OFF button is used to switch the air conditioner on and off. When the air conditioner is switched off, the supply of air from outside the car is cut off.

When the air cooling is switched off, the air is neither cooled nor dehumidified. The windows may mist up as a result. The air cooling is switched off automatically at low outside temperatures (below zero).

To switch on the air recirculation mode, press the button. The bottom LED in the button will light up. In air recirculation mode, the air from the interior of the Audi Q3 is filtered and recirculated. This setting prevents fumes etc. from entering the interior. We recommend switching on the air recirculation mode when driving through a tunnel or in traffic queues WARNING!.

The air recirculation mode is switched off when the AUTO or button is pressed.

To switch on the automatic air recirculation mode, press the button again. The top LED in the button will light up. The air recirculation mode will be switched on automatically if you reverse the Audi Q3 while the engine is cold. If cooling mode (AC) is switched off and the weather is extremely cold, the automatic air recirculation will only operate for a limited time.

The automatic mode maintains a constant temperature inside the Audi Q3. Air temperature, output and distribution are regulated automatically.

Separate temperatures can be selected for the driver's and front passenger's side using the left and right rotary controls. The temperature can be adjusted between +16 °C (+60 °F) and +28 °C (+84 °F). Outside this range, LO or HI will appear on the air conditioner display. In the two extreme settings the air conditioner operates continuously with maximum cooling or heating output, and the temperature is not regulated automatically.

You can adjust the volume of air delivery manually to suit your individual requirements. Press the AUTO button for automatic blower regulation.

You can direct the flow of air manually to selected outlets. The buttons can be operated either separately or in combination. Press the AUTO button for automatic air distribution.

When you press the button, the seat heating is switched on at level 3 (the highest level). The LEDs indicate the temperature level. To reduce the temperature, press the button again. To switch off the seat heating, press the button repeatedly until all the LEDs have gone out.

The seat heating automatically switches from level 3 to level 2 after 10 minutes.

The windscreen and side windows are defrosted or demisted as quickly as possible. The air output is increased to maximum and most of the air comes out of the outlets below the windscreen. The air recirculation mode is deactivated. The temperature should be set to 22 °C or higher.

The defroster is switched off when the AUTO button is pressed.

The rear window heating operates only when the engine is running and switches off automatically after about 10 minutes.

By pressing and holding the AUTO button, you can set the temperature of the front passenger's side to the temperature of the driver's side. The synchronisation is deactivated as soon as the temperature on the front passenger's side is changed.

The thumbwheels can be used to open and close the air outlets in the centre and on either side of the dashboard and rear centre console. The lever in the centre of the outlets can be used to adjust the direction of air flow.

The temperature display can be switched between °C and °F. Press and hold the button Fig. 1 and turn the rotary control on the driver's side to for 3 seconds.
