WARNING
At low outside temperatures, only switch over
to air-recirculation mode for brief periods.
Otherwise, the windows could fog up, thus
impairing visibility and endangering yourself
and others. This may prevent you from
observing the traffic conditions and thereby
cause an accident.
You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle
from outside. The air already inside the
vehicle will then be recirculated.
The operation of air-recirculation mode is the
same for all control panels.
