Air conditioning system
In addition to the heating and

The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above

recirculation mode. Activation is

which may cause the vehicle

In warm and very humid ambient air
conditions, the windscreen might mist
up from outside, when cold air is
