The functions can be switched on/off by pressing the buttons or rotary controls. The LED in the corresponding button or rotary control lights up when the function is switched on.
The air conditioner can be switched on and off by pressing rotary control -2-. The air conditioner will also switch on if you press one of the other buttons or rotary controls. When the air conditioner is switched off, the supply of air from outside the car is cut off.
The air cooling mode is switched on/off when the A/C button is pressed. 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).
The maximum air cooling mode is switched on/off when the 
button is pressed. 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). When the air cooling is switched on, the vehicle interior is cooled and dehumidified as quickly as possible.

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 ►.
The air recirculation mode can be switched on and off by pressing rotary control -3-. The air recirculation mode can also be switched off by pressing the rotary control -1- or the 
button.
button.
The automatic mode maintains a constant temperature inside the vehicle. Air temperature, output and distribution are regulated automatically. The automatic mode can be switched on and off by pressing rotary control -1-.
The temperature can be adjusted between +16 °C (+60 °F) and +28 °C (+84 °F) by turning the rotary control -1-. 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 blower speed manually by turning rotary control -2-. You should leave the blower on at a low setting to prevent the windows from misting up and to ensure that the vehicle interior is constantly ventilated. Press rotary control -1- for automatic control of the blower speed.
By turning rotary control -3-, you can select the air outlets you wish to activate. Press rotary control -1- for automatic control of the 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 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 defrosting mode is switched on/off when the button is pressed. This function can also be switched off by pressing rotary control -1-.

button for at least 3 seconds. It will then remain on until the ignition is switched off.Air outlets
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.
To activate the residual heat function, press and hold rotary control -1- when the ignition is switched off. 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 15 minutes.
- For reasons of safety you should not leave the air recirculation switched on for too long. This mode prevents fresh air from entering the vehicle, so the windows can mist over if the air cooling is switched off. Bad visibility can cause an accident.
- People with limited capacity to feel pain or sense temperature could burn themselves when using the seat heating*. These people must not use the seat heating* - risk of injury!
CAUTION
To avoid damaging the heating elements of the seat heating*, please do not kneel on the seat or apply sharp pressure at a single point.
