Mercedes-Benz GL-Class: Activating/deactivating cooling with air dehumidification
Important information
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.
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.
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/deactivating
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.
► To activate: press the
button.
The indicator lamp in the
button
lights
up.
► To switch off: press the
button.
The indicator lamp in the
button
goes
out. The cooling with air dehumidification
function has a delayed switch-off feature.
Problems with the cooling with air dehumidification function
If the indicator lamp in the
button does
not go out when the function is activated, the
cooling with air dehumidification function is
deactivated due to a malfunction. You can no
longer switch on the cooling with air
dehumidification function.
► Consult a qualified specialist workshop.
