should light up.
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 completely normal and there is no need to suspect a leak.
Note
Keep the air vents in front of the windscreen free of snow, ice and leaves to 
ensure heating and cooling are not impaired and to prevent the windows 
from misting over.

WARNING
Never turn off the air fan for a long time or the air in the passenger compart-
ment will not be refreshed.
 xStuffy or used air will increase fatigue and reduce driver and passenger 
concentration possibly resulting in a serious accident.
Note
Not all Climatronic buttons are operational in REAR mode.
Note
The   button is locked in defrost mode.
Climate control user instructions
The cooling system only works when the engine is running and fan is 
switched on.
The climate control system operates most effectively with the windows and 
the sliding panoramic 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 briefly.
Keep the air vents in front of the windscreen free of snow, ice and leaves to 
ensure heating and cooling are not impaired and to prevent the windows 
from misting over.
Adjustment for safer driving
When the air conditioning is switched on, the temperature and the air 
humidity in the vehicle interior drop. Hence, when the outside air humidity is 
high, the windows do not mist over and comfort for the vehicle occupants is 
improved:

the engine is still warm but the ignition switched off, the heat 
given off by the engine can be used to keep the passenger 
compartment warm. The   button will light up when the 
function is switched on. The function will switch off after 
around 30 minutes and if the battery level is low.
