Heating, Ventilation and Air conditioning 183
Safety First Operating instructions Practical tips Technical Data
WARNING
Never turn off the air fan for a long time or the air in the passenger compart-
ment will not be refreshed.
x Stuffy 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:
