WARNING: When the air conditioning
and heating system is off (knob 3 on
OFF) air enters the passenger
compartment and thus, under certain
environmental conditions or with
more than one person in the car, the
windows could fog up quickly.
If air distribution is selected manually
using knob 2, the simple automatic
mode is obtained: that is, the system
selects fan speed and air mixing to
reach the requested "comfort"
temperature, however, without
4
changing the air distribution selected
manually.
Pressing button 4, corresponding to
the air recirculation function,
automatically reactivates the
compressor, if it has been manually
deactivated, in order to prevent the
windows from fogging up.
108 Air conditioning and heating system
During the automatic operation the
system can automatically activate the
recirculating air function or deactivate
the ventilation compressor to cool/
heat the compartment or to demist/
defrost windshield and front side
windows.
WARNING: When the engine is started,
the system keeps the settings selected
manually prior to switching off.
