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. 124
Operating the climate control systems
Climate control

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.
i
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. Canada only

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. In automatic mode, the set temperature is
maintained at a constant level. The system
automatically regulates the temperature of
the dispensed air, the airflow and the air
distribution.
Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If desired, cooling with air
dehumidification can be deactivated.130
