Alfa Romeo 156 Owner's Manual page 118

The air quality control is also entrusted
to a combined particle and activated carbon
filter.
The climate control system automatically
controls and adjusts the following parame-
ters and functions:
– temperature of the air admitted to the
passenger compartment (for the driver's and
passenger's side separately)
– fan speed
– air distribution
– inside air recirculation on/off
– climate control compressor on/off en-
able.
The settings of the following functions can
be modified manually:
– fan speed
– air distribution
– inside air recirculation on/off
– climate control compressor on/off en-
able
– window defrosting/demisting.
The control of the functions that have not
been modified manually will always be au-
tomatic and, in any case, the temperature
of the air flowing into the passenger com-
partment is controlled automatically de-
pending on the temperatures set on the dri-
ver's and passenger's displays.
WARNING Manual selections prevail
over automatic ones and remain in storage
until the user decides to resume automatic
control. The settings selected manually are
stored when the engine is switched off and
resumed the next time the engine is started.
