Window demisting
In the event of considerable outside mois-
ture and/or rain and/or considerable dif-
ferences in temperature inside and out-
side the passenger compartment, perform
the following preventive demisting proce-
dure:
❒turn air recirculation off by pressing
button G(button led off);
❒turn knob Cto red sector;
❒turn knob Eto 2;
❒turn knob Ato y, or to ™the win-
dows do not demist.
IMPORTANT Climate control system is
very useful to speed up window demist-
ing: therefore, just perform demisting as
previously described and turn the climate
control system on by pressing button B.HEATED REAR WINDOW AND
DOOR MIRROR DEMISTING/
DEFROSTING
Press button Fto start this function.
This function is timed and switches off au-
tomatically after 30 minutes. To cut out
this function press again button
O.
IMPORTANT Do not apply stickers on
the inside of the rear window over the
heating filaments to avoid damage that
might cause it to stop working properly.
FAN SPEED ADJUSTMENT
To ventilate the passenger’s compartment
properly, proceed as follows:
❒open completely central vents and side
outlets;
❒turn knob Cto the blue sector;
❒turn knob Eto the required speed;
❒turn air recirculation off by pressing
button G(button led off);
❒turn knob Ato O.RECIRCULATION
Turn this function on by pressing button
G(button led on).
This function is particularly useful when
the outside air is heavily polluted (in a traf-
fic jam, tunnel, etc.). However, it is bet-
ter not to use it for long periods, espe-
cially if there are several people in the car
to prevent window misting.
IMPORTANT The inside air recirculation
system makes it possible to reach the re-
quired “heating” or “cooling” conditions
faster. Do not use the air recirculation
function on rainy/cold days as it would
considerably increase the possibility of the
windows misting inside.

AUTOMATIC CLIMATE
CONTROL SYSTEM
(where provided)
GENERAL
The car is fitted with a two-zone climate
control system which makes it possible to
separately adjust the air temperature on
the driver’s side and on the passenger’s
side. Temperature control is based on the
“equivalent temperature” logic, i.e.: the
system continuously works to keep con-
stant the comfort inside the passenger
compartment and to compensate any vari-
ation of the outside climate conditions, in-
cluding sunshine detected by a proper sen-
sor provided for the purpose.
The system is also fitted with AQS (Air
Quality System) sensor that turns on air
recirculation automatically when it detects
the presence of outside polluted air (for
example when driving in the city, queues
and tunnels).

DASHBOARD
AND CONTROLS
The climate control system automatically
controls and adjusts the following para-
meters and functions:
❒air temperature at driver/front pas-
senger/rear passenger vents;
❒air distribution at driver/front passen-
ger vents;
❒fan speed (continuous air flow varia-
tion);
❒compressor activation (to cool/dehu-
midify air);
❒air recirculation.All the above functions can be changed
manually by selecting the required func-
tion/s and by changing the set parameters.
In this way the automatic control is de-
activated; the system will resume auto-
matic control only for safety reasons (e.g.
risk of window misting up).
Manual selections prevail over automatic
ones and remain in storage until the user
decides to resume automatic control by
pressing the proper button, except when
the system cuts in for particular safety
conditions.
The control of functions not changed man-
ually remains automatic.
The amount of air admitted to the pas-
senger compartment does not depend on
the car speed, since it is electronically con-
trolled by the fan.The temperature of the air admitted to
the passenger compartment is always con-
trolled automatically according to the tem-
peratures set on the driver’s and front
passenger’s display (except when the sys-
tem is off or under certain conditions
when the compressor is off).
The following parameters and functions
can be set or changed manually:
❒air temperatures on driver/front pas-
senger side;
❒fan speed (continuous variation);
❒air distribution on seven levels (dri-
ver/front passenger side);
❒climate control compressor on/off;
❒monozone/two-zone distribution pri-
ority;
❒fast demisting/defrosting;
❒air recirculation;
❒rear heated window.

SWITCHING THE CLIMATE
CONTROL SYSTEM ON
The system can be started in different
ways, but it is advisable to press one of the
AUTObuttons and then to turn the
knobs to set the temperatures required
on the display.
Since the system controls two zone of the
passenger’s compartment, the driver and
the front passenger can select different
temperatures.This way the system will start working
completely automatically to reach the
comfort temperatures as quickly as pos-
sible. The system will set air temperature,
quantity and distribution and it will con-
trol the air recirculation function and the
activation of conditioner compressor.

During fully automatic operation, the on-
ly manual settings required are the fol-
lowing:
❒MONO, to align the air temperature
and distribution set on the passenger’s
side (front or rear) with that on the
driver’s side;
❒…, air recirculation, to keep it al-
ways on or off;
❒-, to speed up demisting/defrosting
of windscreen, front side windows,
rear window and door mirrors;
❒(, to demist/defrost heated rear win-
dow and door mirrors.During full automatic system operation,
you can change at any time set tempera-
tures, air distribution and fan speed by us-
ing the relevant buttons or knobs: the sys-
tem will automatically change its settings
to adjust to the new requirements. Dur-
ing FULL AUTOoperation, changing air
distribution and/or flow and/or compres-
sor activation and/or air recirculation will
make the FULLwording disappear. In this
way functions will pass from automatic
control to manual control until pressing
again the AUTObutton. Fan speed is the
same for every area of the passenger com-
partment.
With one or more functions engaged man-
ually, the adjustment of the temperature
of the air admitted to the passenger com-
partment continues to be controlled au-
tomatically by the system, except with the
climate control compressor off: under this
condition in fact, the temperature of the
air admitted to the passenger compart-
ment cannot be lower than outside air
temperature.CONTROLS
Air temperature adjusting
knobs P-G
Turning the knobs clockwise or counter-
clockwise, respectively highers or lowers
the temperature of the air required re-
spectively in the front left zone (knob P)
or in the right zone (knob G) of the pas-
senger compartment.
Since the system controls two zones of
the passenger compartment, it is possi-
ble to personalise required temperatures
(driver and passenger).
The temperatures set are shown on the
displays near the relevant knobs.
Pressing button I (MONO) automatical-
ly aligns the temperature on the passen-
ger’s side with that on the driver’s side;
you can therefore set the same tempera-
ture for both zones by turning knob P on
driver side.
Separate operation of air temperatures
and distribution is restored by turning
knobs or pressing again button I
(MONO) when the button led is on.

AND CONTROLS
Turning the knobs fully clockwise or
counter-clockwise until they reach 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). It can be acti-
vated independently from driver or front
passenger side or both (also when the
MONOfunction is selected).
When this function is on, the display
shows HI.
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. This
function uses the maximum temperature
of the coolant fluid, while air distribution
and fan speed are controlled according to
the system settings.
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.
❒LOfunction (highest cooling power):
this is turned on by rotating the temper-
ature knob counter-clockwise and passing
the min. temperature value (16°C). It can
be activated independently from driver or
front passenger side or both (also when
the MONOfunction is selected).
When this function is on, the display
shows LO.
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. This
function activates automatically:
❒MONOfunction;
❒air distribution at central / side vents
(shown by the relevant symbol on the
display);
❒fan at max. speed;
❒climate control compressor.
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.Front air distribution buttons B-F
Pressing these buttons it is possible to
choose manually one of the seven possi-
ble air distributions to the passenger com-
partment (right or left side):
▲Air flow to the windscreen and front
side window vents to demist or de-
frost them.
˙Air flow at central and side dash-
board 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 ten-
dency of heat to spread upwards,
this type of distribution allows heat-
ing of the passenger compartment
in the shortest 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
distribution is particularly useful in
spring and autumn when the sun is
shining.
