General
The vehicle is equipped with an
automatic dual-zone air conditioner/
heater, which is designed to adjust the
air temperature, distribution and flow
in the vehicle's passenger
compartment, in two separate zones:
left-hand side and right-hand side.
In fact, the system can be controlled
from the front by means of panel A,
incorporated in the central console,
and also from the rear, by means of
panel B, housed in the end section of
the console.

The rear instrument panel can be
activated/ deactivated using the REAR
button 12 on the front panel.
When the rear instrument panel B is
active, the front panel A is disabled.
Both instrument panels allow the user
to control the following parameters/
functions:
– left-hand/right-hand air
temperature
– left-hand/right-hand air distribution
– fan speed (stepless change)
– compressor activation
– recirculation.

Air conditioning and heating system
All the functions listed above can be
modified manually, i.e., the user can
select one or more of these functions,
as he/she wishes, using the control
panel.
The manual selections are always given
priority over the automatic ones and
are memorized until the user chooses
the automatic control again.
When a function has been set
manually, the other automatic
functions will not be affected.
The following parameters/functions
can be set/modified manually:
– left-hand/right-hand side air
temperature
– fan speed
– air distribution setting on 7 positions
(left/right)
– compressor activation
– single/dual-zone distribution priority
– defrosting/demisting function (MAX
DEF)
– air recirculation function
– automatic/manual control of the
system
– heated rear window
– system deactivation
– activation of rear control panel.
Activation
The system can be activated in a
number of ways, however, begin by
pressing one of the buttons 10, 13 or
15 AUTO and using the buttons 1, 2, 14
or 16 to set the temperature required.
This way, the system will operate in
fully automatic mode so that the
temperatures set will be reached as
quickly as possible.
In this condition, manual interventions
will activate the following functions:
– MONO button 7 or 17 adjusts the air
temperature and distribution in the
two heating/air conditioning areas.
– REAR button 12 activates the rear
control panel
– button 6 or 19 switches off the
compressor
– button 8 activates/deactivates the
defrosting/demisting function on the
front and side windows
– button 11 activates/deactivates the
heated rear window.
By altering any other parameter
manually, such as the air temperature
or distribution, these features switch
from the fully automatic control mode
(FULL AUTO) to the manual mode
(AUTO).
