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
