The air quality control is also entrusted to
a combined particle and activated carbon
filter. The climate control system automat-
ically controls and adjusts the following
parameters 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 re-circulation on/off
- climate control compressor on/off. The settings of the following functions
can be modified manually:
- fan speed
- air distribution
- inside air re-circulation on/off
- climate control compressor on/off enable.
The control of the functions that have
not been modified manually will always
be automatic and, in any case, the tem-
perature of the air flowing into the pas-
senger compartment is controlled auto-
matically depending on the temperatures
set on the driver’s and passenger’s dis-
plays.IMPORTANTManual selections pre-
vail 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 it
is started.

HOW TO USE
THE AUTOMATIC TWO-ZONE
CLIMATE CONTROL SYSTEM
(fig. 97)
IMPORTANTThe knob rings do not
have a mechanical stopper therefore, once
the maximum or minimum value has been
reached, they are free to turn in both
directions.
The system can be started in different
ways, but it is advisable to set the tem-
peratures required on the displays; then
press the (13)
AUTObutton.
This way the system will start working
completely automatically to reach the
temperatures set as quickly as possible
and then maintain them.
During completely automatic system
operation, the temperatures set can be
changed at any time; the system will auto-
matically change its settings to adjust to
the new requirements. IMPORTANTTo be able to be accepted
by the system, the difference in the tem-
perature between the driver’s and passen-
ger’s side must be within a range of 7°C.
It is possible to personalise the choices
made automatically by the system inter-
veningmanually on the following controls:
- fan speed adjustment knob (4)
- air distribution selection buttons (10)
- inside air re-circulation on/off button
(8)
v
- climate control on enable button (14)
√.
Manually selecting one or more of these
functions turns off the right led on the but-
ton (13)
AUTO.With one or more functions engaged
manually, the adjustment of the tempera-
ture of the air admitted to the passenger
compartment continues to be controlled
automatically by the system (left led on
button13
AUTOon) except with the cli-
mate control compressor off.
In fact, in this condition the air admitted
to the passenger compartment cannot
have a lower temperature than the out-
side air; this condition is indicated by the
turning off of the two leds on button (13)
AUTOand flashing on the display (1)
and/or (5) related with the temperature
rate that cannot be obtained.

This is turned on setting on the display a
temperature below 16.5°C; this setting is
shown on both displays.
This function can be engaged when
requiring to cool the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system.
The function cuts off air heating,
engages inside air re-circulation (to pre-
vent admitting hot air to the passenger
compartment) and the climate control
compressor, takes air distribution to
RE
and the fan speed as set by the system.
All manual settings are possible with this
function on.
To switch the function off, simply turn
the ring of knob (2) or (6) of the tem-
perature set on a value above 16.5°C;
the opposite display will show 16.5°C.
Pressing key (13)
AUTOthe display will
show a temperature of 16.5°C and
returns to an operating condition with
automatic temperature adjustment.

With the climate control compressor off,
it is not possible to admit air to the pas-
senger compartment with a temperature
below the outside temperature; in this
case, the value flashes on the display con-
cerning the temperature that cannot be
reached and the left led on button (13

The switching off of the climate control
compressor remains in storage even when
the engine has been stopped. To restore
