The cooling system for the vehicle interior only works when the engine is running and the blower is switched on.
The air conditioning system operates most effectively with the windows and the electric panorama sliding and tilting glass roof closed. However, if the vehicle has heated up after standing in the sun for some time, the air inside can be cooled more quickly by opening the windows and the electric panorama sliding and tilting glass roof for a short time.
Settings for optimal road visibility
Switching the cooling system on not only reduces the temperature of the vehicle interior, but also the humidity. This improves comfort for the vehicle occupants and prevents the windows from misting when the outside humidity is high.

Things to note
If the humidity and temperature outside the vehicle are high, condensation can drip off the evaporator in the cooling system and form a pool underneath the vehicle. This is normal and does not indicate a leak.
The windscreen may mist up after starting the engine due to residual humidity in the air conditioning system. Switch the defrost function on in order to clear the windscreen of condensation or mist as quickly as possible.
