NOTE:The climate control system detects the passenger
compartment temperature using a mean radiant tem-
perature sensor located in the interior rear view mirror
and protected by a specific cover. Obstructing the field of
view of this sensor with any object could cause the
climate control system to operate with less than optimal
efficiency.
Switching On the Climate Control System
The climate control system can be switched on in differ-
ent ways: it is advisable to press the AUTO button and
turn the knobs to set the desired temperatures.
In this way the system operates completely automatically
to adjust the temperature, quantity and distribution of
the air introduced into the passenger compartment. It
also manages the air recirculation function and the acti-
vation of the air conditioning compressor. During automatic operation, you can change the set
temperatures, air distribution and fan speed at any time
by using the relevant buttons or knobs: the system will
automatically change the settings to adjust to the new
requirements.
During completely automatic operation (AUTO), varying
the air flow and/or distribution (which are not dis-
played) causes the AUTO function LED to disappear and
the system to operate in MANUAL mode (displaying
both the flow and distribution requested).
When the compressor is deactivated, the AUTO opera-
tion remains active only if the system can guarantee
in-car comfort. Otherwise, the system switches to
MANUAL mode (the set temperatures will flash on the
display). The fan speed is the same in all the zones of the
passenger compartment.

To restore automatic control of the air distribution after a
manual selection, press the AUTO button.
AUTO Button
When the AUTO button is pressed (LED on button lit) the
climate control system automatically adjusts the follow-
ing settings in the corresponding zones:
•quantity and distribution of the air introduced into the
passenger compartment
• climate control system compressor and
• air recirculation.
Cancelling all previous manual adjustments.
This is indicated by the LED on the AUTO button
switching on. If the AUTO button is pressed when the AUTO LED is
on, the system switches to completely manual mode; it
displays the current flow and distribution status, which
will no longer be managed automatically.
If a manual intervention is made on at least the air
distribution or on the fan speed, the LED switches off to
indicate that the system is no longer controlling all
functions automatically.
Deactivating the compressor results in the deactivation of
automatic operation only if the system is no longer able
to guarantee comfort conditions (which depend on the
set temperature).
NOTE:
Should the system no longer be able to guarantee
the required temperature set in various passenger com-
partment zones, the set temperature value will flash for a
few seconds on the display.
