HI function
(highest heating power - fig. 99)
This is turned on setting on the display a
temperature above 32.5°C, and can be
activated 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
requiring to heat the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system.
This function uses the maximum temper-
ature of the coolant fluid, while air distrib-
ution and fan speed are controlled accord-
ing 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 tempera-
ture set to a value below 32.5°C; the
opposite display will show 32.5°C.

LO function
(highest cooling power - fig. 100)
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)

cally aligns the temperature on the pas-
senger’s side with that on the driver’s
side, therefore it is possible to set the
same temperature between the two zones
simply turning 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.

FAN SPEED
ADJUSTMENT KNOB
(fig. 102-103)
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)

AIR DISTRIBUTION SELECTION
BUTTONS
(fig. 104)
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
Zvents to the lower part of the pas-
senger compartment (warmest air)
and the dashboard centre and side ou-
tlets and the rear outlet (coolest air).
The air flow distribution is particularly
useful in spring and autumn, when
the sun is shining.
ZAir flow towards the front and rear
lower parts of the passenger com-
partment. Due to the natural ten-
dency 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.
A0A0208b
QSplitting of the air flow between the
Zwindscreen and side window defro-
sting/demisting vents and the lower
part the of the car. This type of air di-
stribution allows satisfactory heating
of the passenger compartment while
preventing misting of the windows.
QAir flow to the windscreen and front
side window vents to demist or de-
frost them. IMPORTANTPressing one of these
buttons turns on (led on button itself on)
or off (led on button off) the associated
functions if the combination chosen is
among the 5 possible ones; if not it only
activates the main function of the button
pressed, without the possibility of turning
off with another press (at least in one dis-
tribution the air flow should be spread in
the passenger compartment).
To restore automatic air distribution con-
trol after a manual selection, press button

turns on, or press button (13)AUTO; in
which case, however, the other manual
settings set will be cancelled.
CLIMATE CONTROL
COMPRESSOR ON/OFF
ENABLE BUTTON
(fig. 105)
Pressing button (14)
√enables the
turning on of the climate control compres-
sor. 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-circulation pressing button (8)
v.
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
AUTO- fig. 106) goes off.
The switching off of the climate control
compressor remains in storage even when
the engine has been stopped. To restore
automatic control for switching on the cli-
mate control compressor, press button
(14)
√again, the led on the buttonOperation of the climate
control compressor is nec-
essary for cooling and de-
humidifying the air; it is advisable
to keep this function always on, to
prevent window misting problems.

INSIDE AIR RE-CIRCULATION
ON/OFF BUTTON
(fig. 107)
Inside air re-circulartion is controlled
according to three operating logics:
- automatic control, indicated by the
turning on of the right led on the button;
- forced engagement (inside air re-circu-
lation 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-circu-
lation always off with air inlet from out-
side), indicated by the turning off of both
leds.
These operating conditions are obtained
pressing in sequence the inside air re-cir-
culation button (8)
v.
When inside air re-circulation is con-
trolled automatically by the system, the
right led on the air re-circulation button
(8)
vstays 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-cir-
culation is turned automatically when the
antipollution sensor detects the presence
of polluted air, for example in cities,
queues, tunnels and operation of the
windscreen washer (with the typical smell
of spirits). The inside air- re-circula-
tion system makes it pos-
sible to reach the required
“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.
A0A0212b
With low external tem-
perature the climate con-
trol compressor is unable
to work. It is therefore inadvisable
to use the inside air recirculation
function
vwith low outside tem-
perature as windows may mist
over quickly.
fig. 107

GETTING TO KNOW YOUR CAR

It is advisable to turn on
the inside air re-circulation
system in queues or tunnels
to avoid admitting polluted air from
outside. The prolonged use of this
function should however be avoid-
ed, especially with several persons
on board, to avoid the possibility of
the windows misting inside.
AUTOMATIC OPERATION AUTO
BUTTON
(fig. 108)
Pressing the (13)
AUTObutton the sys-
tem automatically adjusts the amount and
distribution of the air admitted to the pas-
senger compartment, cancelling all the
previous manual adjustments.
This condition is indicated by the lighting
up of both leds on the button itself. When the right led, on button (13)
AUTO
is off, this means that one or more manual
operations have been carried out and there-
fore automatic control is not complete
(except temperature control which is always
automatic) indicated by the left led on, or
that the system is in the
OFFcondition. In certain weather condi-
tions (e.g.: outside tem-
perature around 0°C) and
with automatic air re-circulation
control on, mist may form on the
windows. In this case press the in-
side air re-circulation button (8)
v, to switch off re-circulation
(leds on button off) and if neces-
sary increase the flow of air to the
windscreen.
