The climate control system can be
deactivated also by the rear control
panel, when operating: press repeat-
edly or keep pressed button 7 (fig.
122) until all the fan bars on the dis-
play turn off and message OFF is
displayed.
To exclude the rear control panel,
press again button REAR; the but-
ton led turns off and the front-seat
passenger's controls are operating
again.
Air recirculation on/off button
(3 fig. 121)
The air recirculation function is
controlled according to three strate-
gies:
– automatic operation (button left
led on);
– forced ventilation on (recircula-
tion always on), the right led on the
button will come on;
– forced deactivation off (recircula-
tion always off, air taken from the
outside), both leds on the button will
go off.
The three conditions are obtained
by pressing the air recirculation but-
ton 3 in sequence.
When the air recirculation function
is automatically controlled by the
system, the left led on the air recir-
culation button is turned on, while
the right led is on or off according to
the actual recirculation conditions
(on or off).
During automatic operation, the
recirculation function is automati-
cally switched on when the pollution
sensor detects the presence of pollut-
ed air, e.g. in cities, queues, tunnels
and during windscreen wiper opera-
tion (due to the characteristic smell
of alcohol).
In addition, if the compressor is on
and the outside temperature is over
5 °C, to prevent air polluted by
exhaust gases getting inside the pas-
senger compartment during stops,
the system stops air recirculation
when the car speed is lower than 6
km/h. When the car speed returns
over 12 km/h, the system restores
the previous conditions.
After using the air recirculation
function for a long time (over 15
consecutive minutes), the system
automatically stops it for safety rea-
sons, thus letting air be changed.
When air recirculation manual
control is set (button left led off),
message FULL on the display is off.
