AIR TEMPERATURE
ADJUSTMENT KNOBS
(fig. 78)
Turning the rings of knobs (2or6), clock-
wise or counter-clockwise, respectively high-
ers or lowers the temperature of the air re-
quired respectively in the left zone (knob 2)
or right zone (knob 6) of the passenger
compartment. The temperatures set are
shown on the displays (1) and (5) above
the knobs.
Separate operation of the temperatures set
is restored automatically using knob (6).
Turning the knob rings clockwise or
counter-clockwise until they reach the ex-
treme selections HIorLO, the maximum
heating or cooling functions are respective-
ly engaged:

HI function
(highest heating power - fig. 79)
This is turned on setting on the display a
temperature above 32.5°C, and can be ac-
tivated independently from the driver’s or
passenger’s side or both; this setting brings
the system to the “monozone” mode and
is shown on both displays.
This function can be engaged when re-
quiring to heat the passenger compartment
as quickly as possible, exploiting the maxi-
mum potential of the system.
This function uses the maximum temper-
ature of the coolant fluid, while air distribu-
tion and fan speed are controlled according
to the system settings.
This function is unadvisable with
the engine cold to prevent admit-
ting air that is not warm enough to
the passenger compartment.
All manual settings are possible with this
function on.
To switch the system off, simply turn the
ring of knob (2) or (6) of the temperature
set to a value below 32.5°C; the opposite
display will show 32.5°C.

LO function
(highest cooling power - fig. 80)
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 re-
quiring to cool the passenger compartment
as quickly as possible, exploiting the maxi-
mum potential of the system.
The function cuts off air heating, engages
inside air re-circulation (to prevent admitting
hot air to the passenger compartment) and
the climate control compressor, takes air dis-
tribution to
REand 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 temperature
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.

MONO BUTTON FOR
ALIGNMENT OF THE
TEMPERATURES SET
(fig. 81)
Pressing button (12)
MONOautomatically
aligns the the temperature on the passen-
ger’s side with that on the driver’s side,
therefore it is possible to set the same tem-
perature between the two zones simply turn-
ing the ring of knob (2) on the driver’s side.
This function is provided to simplify tem-
perature adjustment of the whole passen-
ger compartment when only the driver is on
board.
Separate operation of the temperatures set
is automatically restored when the passen-
ger uses the ring on knob (6) or presses
button (12)

FAN SPEED
ADJUSTMENT KNOB
(fig. 82-83)
Turning the ring of knob (4), clockwise
or counter-clockwise, increases or decreas-
es the speed of the fan, thus the amount
of air admitted to the passenger compart-
ment; the 16 selectable speeds are shown
on a bar (in steps of 3) up to a maximum
of 6 bars lit:
- maximum fan speed = all bars lit;
- minimum fan speed = one bar lit.
The fan can be cut off (all bars off) only
if the climate control compressor has been
switched off pressing button (14)
√. To
restore automatic fan speed control, after a
manual adjustment, press button (13)
AUTO. Completely turning the ring of knob
(4) counter-clockwise switches the system
off, with the following situation: display (1)
off; display (5) off; centre display (3) with

the passenger compartment.
To turn the system on again, simply turn
the ring of knob (4) clockwise, or press any
one button, except the inside air re-circula-tion (8) and rearscreen heating (9) but-
tons; this operation restores all the operating
conditions stored previously.IMPORTANTOn leaving the

AIR DISTRIBUTION SELECTION
BUTTONS
(fig. 84)
Pressing one or more buttons (10) it is
possible to manually choose one of the 5
possible air distributions to the passenger
compartment:
REFlow of air to the dashboard centre
and side outlets and rear outlet.
RESplitting 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 and the rear outlet (coolest
air). This air flow distribution is par-
ticularly useful in spring and au-
tumn,when the sun is shining.
ZAir 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
shortest time, also giving a prompt
feeling of warmth to the coldest parts
of the body.
A0A0208m
QSplitting of the air flow between the
windscreen and side window defrost-
ing/demisting vents and the lower
part of the vehicle. This type of air dis-
tribution allows satisfactory heating
of the passenger compartment while
preventing possible misting of the win-
dows.
QAir flow to the windscreen and front
side window vents to demist or de-
frost them.IMPORTANTPressing one of these but-
tons turns on (led on button itself on) or off
(led on button off) the associated function
if the combination chosen is among the 5
possible ones, if not it only activates the
main function of the button pressed, with-
out the possibility of turning off with another
press (at least in one distribution the air flow
should be spread in the passenger com-
partment).
To restore automatic air distribution control
after a manual selection, press button (13)
AUTO.

COMPRESSOR ON/OFF ENABLE
BUTTON
√(fig. 85)
Pressing button (14)
√enables the turn-
ing on of the climate control compressor.
This condition is shown by the lighting up of
the led on the button itself.
When the climate control compressor is
turned off, the leds on buttons (13)
AUTO
and (14)√go off; automatic inside air re-
circulation control is also excluded (both leds
off on button 8
v) which always stays
off to prevent misting the windows; even
if unadvisable, it is still possible to restore
automatic operation of inside air re-circula-
tion pressing button (8)
v.
With the climate control compressor off, it
is not possible to admit air to the passenger
compartment with a temperature below
the outside temperature; in this case, the
value flashes on the display concerning the
temperature that cannot be reached and the
left led on button (13

goes off.
The switching off of the climate control
compressor remains in storage even when
the engine has been stopped. To restore au-
tomatic control for switching on the climate
control compressor, press button (14)

INSIDE AIR RE-CIRCULATION
ON/OFF BUTTON
v(fig. 87)
Inside air re-circulation is controlled ac-
cording to three operating logics
- automatic control, indicated by the turn-
ing on of the right led on the button;
- forced engagement (inside air re-circula-
tion always on), indicated by the turning on
of the left led on the button (and by the right
led going off at the same time);
- forced switching off (inside air re-circula-
tion always off with air inlet from outside),
indicated by the turning off of both leds.
These operating conditions are obtained
pressing in sequence the inside air re-circu-
lation button (8)
v.
When inside air re-circulation is controlled
automatically by the system, the right ledon the air re-circulation button (8)
v
stays on all the time and the left led shows
the air re-circulation condition:
on= air re-circulation operating;
off= air re-circulation off.
If inside air re-circulation has been turned
on or off manually, the led on button (13)
AUTOturns off.
In automatic operation, inside air re-circu-
lation is turned on automatically when the an-
tipollution sensor detects the presence of pol-
luted air, for example in cities, queues, tun-
nels and operation of the windscreen wash-
er (with the characteristic smell of spirit).

With the outside temper-
ature below 4°C the cli-
mate control compressor is unable
to work. It is therefore unadvis-
able to use the inside air re-circu-
lation feature
vwith low out-
side temperature as the windows
may quickly mist over.
WARNING
Operation of the climate con-
trol compressor is necessary
for cooling and dehumidifying the air;
it is advisable to keep this function
always on, to prevent window mist-
ing problems.
