Points to observe before use
WARNING
If you switch off the cooling function, the vehicle will not be cooled when 
weather conditions are
warm. The windows can fog up more quickly. Window fogging may impair visibility 
and endanger
you and others.
The cooling with air dehumidification function is only available when the engine is running.
The air inside the vehicle is cooled and dehumidified according to the temperature selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is normal and not a sign that there is a malfunction.
The cooling with air dehumidification function uses refrigerant R134a. This coolant does not contain chlorofluorocarbons, and therefore does not damage the ozone layer.
Activating the cooling with air dehumidification function
If the cooling with air dehumidification does not switch on, it is possible that the climate control system has lost coolant.
Have the cooling with air dehumidification checked at a qualified specialist workshop.
