Automatic climate control
90n
Automatic recirculated-air control
(AUC)
You can respond to unpleasant
external odors by temporarily
stopping the flow of outside air. The
system then recirculates the air
currently within the vehicle.
Press the button repeatedly to select
one of three different operating modes.
> Indicator lamps off: outside airflow is
on
> Left indicator lamp on – AUC mode:
the system recognizes pollutants in
the outside air and blocks the flow of
air when necessary. The system then
recirculates the air currently within the
vehicle. Depending on the air quality,
the automatic system then switches
back and forth between outside air
supply and recirculation of the air
within the vehicle
> Right indicator lamp on: the flow of
external air into the vehicle is perma-
nently blocked. The system then
recirculates the air currently within
the vehicle.
If the windows fog over in the
recirculated-air mode, switch it off
and increase the air supply as
required.<

approx. 39 7 (+4
