The functions can be switched on and off using the buttons and controlled using the rotary controls. The LED in the corresponding button lights up when the function is switched on.
Manual air conditioner*
For a comfortable climate inside the vehicle using the air conditioner:
- In the summer, adjust the temperature to just a few degrees below the outside temperature
- Do not turn the blower up too high
- Do not point the air outlets directly at the occupants
The air cooling system only works when the blower is switched on. 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 not cooled and therefore not dehumidified. The windows may mist up as a result. The air cooling is switched off automatically at low outside temperatures.
You can adjust the blower speed manually using 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. To demist the windows, we recommend that you increase the blower speed and set control -3- to

The rotary control -3- can be used to adjust the air distribution. A setting between

The round air outlets in the dashboard can be adjusted link►.
To prevent the front side windows from misting up in wet weather, it s a good idea to open the side air outlets and point them to the side.
Foot-level air outlets are provided underneath the front seats to heat the rear cabin.
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 is switched off when the control is in the defrost position .

If the rear window heating is activated with the ignition switched on, the battery management determines whether or not the vehicle battery charge level is sufficient for the rear window heating to be switched on. Otherwise the rear window heating operates when the engine is running, and switches off automatically after about 10 - 20 minutes, depending on the outside temperature.
To switch on the rear window heating permanently, press and hold the 
button for at least 2 seconds. This setting will be stored for approximately 15 minutes after the ignition is switched off.

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 about 10 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.
Note
- The setting for the driver s seat heating is assigned to the key in use.
- If the passenger s seat heating was on when you last switched off the ignition, it will be switched on automatically only if the ignition is switched on again within 10 minutes.
