Air temperature
adjusting knob (I)
temperatura
Turning the knob
clockwise or counter-clockwise,
respectively raises or lowers the
temperature of the air required in the
passenger compartment.
Set temperature is shown on the
display.
Turning the knob fully clockwise or
counter-clockwise until it reaches the ex-
treme selections HI or LO, the maximum
heating or cooling functions are respec-
tively engaged:
❒HI function (highest heating power):
this is turned on by rotating the temper-
ature knob clockwise and passing the max.
temperature value (32 °C).
This function can be engaged when re-
quiring to heat the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system. Under
these conditions, the system is no longer
controlled by the automatic temperature
adjustment system and sets air mixing to
maximum heating by modulating speed
and air distribution.
More particularly, max. fan speed will not
be immediately engaged if coolant is not
hot enough; this to prevent admitting air
that is not warm enough to the passenger
compartment.
All manual settings are possible with this
function on.To switch the function off, simply turn the
knob counter-clockwise and set the re-
quired temperature.
❒LO function (highest cooling power:
this is turned on by rotating the temper-
ature knob counter-clockwise and passing
the min. temperature value (16 °C).
This function can be engaged when re-
quiring to cool the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system. Under
these conditions, the system is no longer
controlled by the automatic temperature
adjustment system and sets air mixing to
maximum cooling by modulating speed
and air distribution. All manual settings are
possible with this function on.
To switch the function off, simply turn the
knob clockwise and set the required tem-
perature.

Air distribution
buttons (B)
Pressing these buttons it
is possible to choose manually one of the
seven possible air distributions:
▲Air flow to the windscreen and front
side window vents to demist or de-
frost them.
˙Air flow at central and side dashboard
vents to ventilate the chest and the
face during the hot season.
▼Air flow towards the front and rear
lower parts of the passenger com-
partment. Due to the natural tenden-
cy of heat to spread upwards, this type
of distribution allows heating of the
passenger compartment in the short-
est time, also giving a prompt feeling
of warmth.
˙Splitting of the air flow between the ▼vents to the lower part of the pas-
senger compartment (warmest air)
and the dashboard centre and side
outlets (coolest air). This air flow dis-
tribution is particularly useful in spring
and autumn when the sun is shining.
▲Splitting of the air flow between the ▼windscreen and front side window
demisting/defrosting vents and the
lower part of the passenger compart-
ment. This type of air distribution al-
lows satisfactory heating of the pas-
senger compartment while preventing
possible misting of the windows.
▲Splitting of the air flow between the
˙windscreen and front side window
demisting/defrosting vents and the
dashboard centre and side outlets.
This air flow distribution enables to
obtain satisfactory cooling of the pas-
senger's compartment and to keep the
required cooling condition in summer.
▲Splitting of the air flow between the ˙windscreen and front side window ▼demisting/defrosting vents, dashboard
centre and side outlets and the lower
part of the passenger compartment.
This air flow distribution enables to
keep good overall comfort conditions
both in summer and in winter.
Lighting up of the relevant button leds
shows the type of air distribution select-
ed.
To restore automatic air distribution con-
trol after a manual selection, press button
AUTO.

Fan speed adjusting
buttons (H)
Press button Hends to
increase or to decrease the fan speed and
therefore the amount of air admitted into
the passenger compartment, the system
will however keep the required
temperature.
The fan speed is shown by the lit bars on
the display
❒Max fan speed = all bars lit
❒Min fan speed = one bar lit.
The fan can be cut off only if the climate
control compressor has been switched off
pressing button F-fig. 51.
IMPORTANT To restore automatic fan
speed control after a manual adjustment,
press button AUTO.
IMPORTANT At high vehicle speed, the
dynamic effect increases the air flow inside
the passenger compartment that will not
be directly correlated with the lit fan
speed bars.AUTO button (A)
(automatic
operation)
Pressing the AUTO
button the system automatically adjusts
the amount and distribution of the air
admitted to the passenger compartment,
cancelling all the previous manual
adjustments.
This condition is indicated by the message
FULL AUTO on the front display.
Manual operation of at least one automatic
function (air recirculation, air distribution,
fan speed or climate control compressor off)
will cause FULL message going off the dis-
play. This means that automatic control is
not complete (except temperature control
which is always automatic).

and by symbol íon the display;
❒forced switching off (air recirculation
always off with air inlet from the out-
side), indicated by the turning off of
the led on the button and by symbol
êon the display.
The above operating conditions are ob-
tained by pressing in sequence the air re-
circulation button G.
IMPORTANT The inside air recirculation
system makes it possible to reach the re-
quired heating or cooling conditions faster.

It is however inadvisable to use it on
rainy/cold days as it would considerably
increase the possibility of the windows
misting inside, especially if the climate con-
trol system is off.
With low outdoor temperatures, recir-
culation is turned off (with air intake from
outside) to prevent possible misting.
It is inadvisable to use the inside air re-
circulation function with low outside tem-
perature as windows may mist over quick-
ly.Climate control
compressor on/off
button (F)
Press pushbutton √to
turn off the climate control system
compressor if it was on previously and
the logo on the display is turned off.
When the pushbutton is pressed with
the led off, control of compressor
activation is restored to automatic
control by the system. This condition is
indicated by the logo lighting up on the
display.
When turning the compressor off, the sys-
tem will deactivate air recirculation to pre-
vent window misting up. Although the sys-
tem is able to keep the required tempera-
ture, the wording FULL will disappear from
the display. If the system is no longer able
to keep the required temperature, tem-
perature figures will flash and the wording
AUTO will disappear from the display.IMPORTANT With the climate control
compressor off, it is not possible to admit
air to the passenger compartment with a
temperature below the outside tempera-
ture; moreover, under certain environ-
mental conditions, windows could mist up
fastly since air is not dehumidified.
The switching off of the climate control
compressor remains in storage even when
the engine has been stopped.
To restore automatic control for switch-
ing on the climate control compressor,
press again button √(in this event the sys-
tem will just work as heater) or press but-
ton AUTO.
