The OFF button is used to switch the air conditioner on and off. The air conditioner will also switch on if you press the rotary control. The OFF button in the rear cabin just switches the rear air conditioning on/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).

In air recirculation mode, the air from the interior of the vehicle 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.

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

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. Press the AUTO button for automatic air distribution.

When you press the button, the seat heating/ventilation 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/ventilation, press the button repeatedly until all the LEDs have gone out.

The seat heating/ventilation 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 temperature is regulated automatically.

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 to 20 minutes, depending on the outside temperature.

To switch on the rear window heating permanently, press and hold the button for at least 3 seconds. It will then remain on until the ignition is switched off.

When synchronisation is activated, the settings for the driver's side (with the exception of seat heating/ventilation^*) are applied to the front passenger's side. On the 3-zone/4-zone deluxe automatic air conditioner^*, the rear cabin is also synchronised. The synchronisation is deactivated as soon as any adjustments are made on the front passenger's side or in the rear cabin^*.

If you press and hold one of the rotary controls, the settings will be synchronised on the other side of the same row (i.e. front or rear). For example, if you press and hold the rotary control on the front passenger's side, the settings on the driver's side are matched to the settings on the passenger's side.

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 and the outlets in the door pillars. The lever in the centre of the outlets can be used to adjust the direction of air flow.

Press and hold the button when the ignition is switched off to activate the "residual heat" function. The system will then heat the interior using the remaining heat in the engine coolant. The residual heat function will be switched off after about 30 minutes.
