It is advisable not to use the air recirculation func-
tion when the outside temperature is low to pre-
vent the windows from rapidly misting up.
Turning the AQS (Air Quality System)
function on
The AQS function automatically activates internal air recirculation
when the outside air is polluted (e.g. in traffic queues and tunnels).
IMPORTANT With the AQS function active, after the internal air
recirculation system has been running for a certain time, the cli-
mate control system enables the intake of outside air for approx-
imately 1 minute. This takes place regardless of the pollution lev-
el of the outside air.
IMPORTANT The air recirculation system makes it possible to reach
the required heating/cooling conditions faster. It is, however, in-
advisable to use it on rainy/cold days as it would considerably in-
crease the possibility of the windows misting up inside (especially
if the climate control system is off). When the outside tempera-
ture is low, recirculation is forced off (air drawn from the outside)
to prevent the windows misting up.
In automatic operation inside air recirculation will be controlled auto-
matically by the system according to outside environmental condi-
tions.
AIR RECIRCULATION AND AQS
(Air Quality System) FUNCTION
The air recirculation is managed according to the following oper-
ating logics:
❍automatic engagement: A word on B button on;
❍forced engagement (air recirculation always on): LED on v
A button on and A word off;
❍forced disengagement (air recirculation always off, air taken
from the outside): the LED on
vA buttons will switch off
and the A word on B button will switch off.
Forced on/off mode can be selected by pressing button
vA..
When
g(E button off ) is pressed, the climate control system
automatically activates air recirculation (the LED on
vA but-
ton should be on). Press
vA button to turn external air recir-
culation on (LED on button lit) and vice versa.
AQS (Air Quality System) function cannot be operated when
g
button is pressed (LED on button off).

CLIMATE CONTROL SYSTEM COMPRESSOR
Press C to turn the compressor on/off (the LED on the button will
light up when the compressor is on). The system remembers that
the compressor has been switched off, even after the engine has
stopped.
When the compressor is switched off the system deactivates air re-
circulation to prevent the windows from misting up and deactivates
the AQS function. In this case, although the system is capable of
maintaining the required temperature, the AUTO LED will go out.
The temperatures will flash for a few seconds if the required tem-
perature cannot be maintained.
To restore automatic control for switching on the climate control
compressor, press C button again or press the AUTO button.
With compressor off:
❍if the outside temperature is higher than the set one, the sys-
tem will not be able to satisfy the request. The temperature
value will then flash on the display for a few seconds;
❍the fan speed can be manually reset.
When the compressor is on and the engine is running, manual ven-
tilation cannot drop under the maximum speed (only one LED on).
IMPORTANT With the climate control compressor off, it is not pos-
sible to admit air into the passenger compartment with a tempera-
ture below the outside temperature; moreover, under certain envi-
ronmental conditions the windows could mist up very quickly since
the air cannot be dehumidified.
RAPID WINDOW DEMISTING/DEFROSTING
(MAX-DEF function)
Press-to turn windscreen and side window demisting/defrosting
function on (LED on button lit). The climate control system carries
out the following operations:
❍switches on the climate control compressor when climatic con-
ditions allow;
❍turns air recirculation off;
❍sets maximum air temperature (HI) in both zones;
❍sets proper fan speed according to the engine coolant tem-
perature;
❍directs air flow to the windscreen and front side windows vents;
❍the heated rear windscreen is turned on
❍shows fan speed (LED G lit).
IMPORTANT The MAX-DEF function will remain on for approximately
3 minutes from when the engine coolant reaches adequate tem-
perature.
The LED on the AUTO button will go out when the function is on.
With the function activated the only possible manual adjustments
are adjusting the fan speed and the turning the heated rear wind-
screen off. By pressing B, C,
-or AUTO buttons, the climate
control system will turn the MAX-DEF off.

DEMISTING/DEFROSTING
HEATED REAR WINDSCREEN
Press(to turn heated rear windscreen demisting/defrosting func-
tion on (LED on button lit). This function switches off automatically
after about 20 minutes or when the engine is turned off. It is not
switched on automatically the next time the engine is started. For
versions/markets, where provided, pressing the
(button it is al-
so possible to defrost/demist the external rearview mirrors (for
versions/markets, where provided) and the heated spray nozzles
(for versions/markets, where provided).
IMPORTANT Do not affix stickers to the inside of the heated rear
windscreen on the heating filaments, to avoid damage that might
cause them to stop working properly.
Thermal comfort windscreen
(for versions/markets, where provided)
Some versions feature a thermal comfort windscreen which, with
the car exposed to the sun, limits the extent of temperature in-
crease inside the passenger compartment, thus ensuring greater
comfort.
Humidity sensor (for versions/markets, where provided)
The humidity sensor prevents the windows from misting up. For
full operation, it is advisable to turn the AUTO on (LED N on). When
the outside temperature is low, the system could automatically turn
the compressor on and turn air recirculation off for safer driving.
TURNING THE CLIMATE CONTROL SYSTEM OFF
Pressgbutton (LED on button off):
❍air recirculation is on, thus isolating the passenger compartment
from the outside;
❍the compressor is off;
❍the fan is off.
❍the heated rear windscreen can be switched on or off.
❍the AQS (Air Quality System) function cannot be turned on.
IMPORTANT The climate control system control unit stores the tem-
peratures set before the system was switched off and restores
the same conditions when any button of the system is pressed (ex-
cept for D button).
Press AUTO button to restart the climate control system in fully
automatic mode.

NOTEWhen the Start&Stop function is active (engine off and
vehicle speed zero), the automatic recirculation management is
turned off always taking air in from outside, to reduce the proba-
bility of window misting up (as the compressor is off).
SUPPLEMENTARY ELECTRIC HEATER
(for versions/markets where provided)
This device speeds up passenger compartment warming when it is
very cold. The additional heater turns off automatically after reach-
ing the required comfort conditions.
Automatic dual zone climate control system
(for versions/markets, where provided)
The supplementary electric heater is operated automatically ac-
cording to environmental conditions and when the engine is run-
ning.
Manual climate control system
The supplementary heater is activated automatically by turning A
knob to the end of the red section and setting the fan (knob B)
to at least the 1
stspeed.
IMPORTANT NOTES
The heater only works if the outside temperature and engine coolant
temperature are low.
The heater will not activate if the battery voltage is too low.
START&STOP
Automatic climate control system
The automatic climate control system manages the Start&Stop
function (engine off when speed is zero) to ensure adequate com-
fort inside the passenger compartment.
Specifically, the Start&Stop function is turned off when the weath-
er is particularly hot or cold to guarantee an adequate level of com-
fort inside the passenger compartment; therefore, the engine will
not be stopped during these transient conditions, even if the speed
is zero.
When the Start&Stop is on and the engine is off at zero speed,
the climate control system will turn the engine back on if the in-
side temperature conditions should rapidly deteriorate (or if the
user asks for maximum cooling – LO – or quick demisting –
MAX-DEF).
With the Start&Stop function on and engine off at zero speed,
air flow is reduced to the minimum to main comfort conditions in-
side the passenger compartment as long as possible when the sys-
tem is in AUTO mod (LED N on).
The climate control system attempts to manage the discomfort
caused by the engine stopping (compressor and engine coolant
pump off) but operation of the climate control system can be priv-
ileged by turning the Start&Stop off by pressing the button on
the dashboard.
NOTEIn particularly severe climate conditions it is recommen-
ded to limit the use of the Start&Stop function to prevent the com-
pressor from continuously switching on and off, with following fa-
st window misting and accumulation of humidity with unpleasant
smells in the passenger compartment.

FAILED ENGINE CUT-OUT CONDITIONS
When the system is operating, due to comfort, emission control
and safety reasons, the engine does not stop in some conditions,
among which:
❍engine still cold;
❍very cold outside temperature;
❍battery not sufficiently charged;
❍heated rear windscreen on;
❍windscreen wipers working at maximum speed;
❍particulate filter regeneration in progress (diesel engines only);
❍driver’s door not shut;
❍driver’s seat belt not fastened
❍reverse gear engaged (for example, for parking manoeuvres);
❍for versions equipped with dual zone automatic climate control
system (for versions/markets, where provided), if an adequate
level of thermal comfort has not been reached or MAX-DEF func-
tion activation;
❍during the first period of use, to initialize the system;
In these cases, a message is shown on the display and the sym-
bol
Uwill blink (the latter for versions/markets, where provid-
ed).

Notes
If the clutch is not pressed, after 3 minutes from the engine stop-
ping, the engine can be restarted only using the ignition key.
In cases when the engine stops and this is not desired, due for
example to the clutch pedal being released sharply with a gear
engaged, if the Start&Stop system is activated, the engine can
be restarted by fully depressing the clutch pedal or by placing the
gear lever in neutral
RESTARTING CONDITIONS
For reasons of comfort, limiting harmful emissions and safety pur-
poses, the power unit can restart automatically without any action
on behalf of the driver if certain conditions are met, including:
❍battery not sufficiently charged;
❍windscreen wipers working at maximum speed;
❍low braking system vacuum, e.g. following the brake pedal be-
ing pressed repeatedly;
❍car in motion, for example when driving on hilly roads;
❍stopping the engine using Start&Stop longer than approxi-
mately 3 minutes;
❍for versions equipped with dual zone automatic climate control
system (for versions/markets, where provided), if an adequate
level of thermal comfort has not been reached or MAX-DEF func-
tion activation;
With gear engaged, the automatic engine restarting is possible on-
ly by fully pressing the clutch pedal. This operation is indicated to
the driver by means of a message on the display and by symbol
Ublinking (the latter for versions/markets, where provided).

SAVING FUEL
Here are some suggestions which may help you to save fuel and
lower the amount of harmful emissions released into the atmos-
phere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out in accordance with the
“Scheduled Servicing Plan” (see chapter “Servicing and mainte-
nance”).
Tyres
Check the tyre pressure at least once every 4 weeks: if the pres-
sure is too low, consumption levels increase as resistance to rolling
is higher.
Unnecessar y loads
Do not travel with an overloaded boot. The weight of the car and
its arrangement greatly affect fuel consumption and stability.
Roof rack/ski rack
Remove the roof rack or the ski rack from the roof after use. These
accessories decrease aerodynamic penetration and have a nega-
tive effect on fuel consumption. It is better to use a trailer to trans-
port particularly bulky objects.
Electric devices
Use electric devices only for the amount of time needed. The heat-
ed rear windscreen, additional headlights, windscreen wipers and
heater fan require a considerable amount of energy; increasing the
current uptake increases fuel consumption (by up to +25% in an
urban cycle).
Climate control system
Using the climate control system will increase consumption: use
the air vents when the external temperature so allows.
Spoilers
The use of non-certified spoilers may adversely affect aerodynam-
ics and fuel consumption.
