Economical operation of the air conditioner will help to save fuel.

When the air conditioner is operating in the cooling mode it reduces engine power and increases fuel consumption. To ensure that the cooling mode is activated only when really necessary, please note the following points:
Ц Switch off the cooling mode by pressing the AC button (LED off) if you wish to save fuel.
Ц You should also switch off the cooling mode by pressing the AC button (LED off) if you open the windows or the tilting panorama roof* while driving.
Ц If the vehicle has heated up after standing in the sun, open the windows and doors for a short time to cool the vehicle.

For the sake of the environment By saving fuel you also reduce the amount of pollutants emitted from your vehicle.
