❒forced deactivation (air recirculation
always off, air drawn in from the
outside): indicated by the LED on
buttons
switching off and text A
on button B off.
Forced activation/deactivation can be
selected by pressing button
.
When the
button is pressed (button
E off), the climate control system
automatically activates internal air
recirculation (LED on
button A
on). It is still possible to activate outside
air recirculation (LED on the button off)
and vice versa, by pressing button
.
The AQS (Air Quality System) function
(for versions/markets, where provided)
cannot be activated when the
button
is pressed (LED on button E off).
AQS (Air Quality System)
function activation
(for versions/markets, where provided)
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 a preset time interval of the
internal air recirculation system
functioning, the climate control system
enables the intake of outside air for
approximately one minute to change
the air in the passenger compartment.
This takes place regardless of the
pollution level of the outside air.
IMPORTANT The engagement of the
recirculation system makes it possible
to reach the required heating/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
up inside (especially if the climate
control system is off). When the outside
temperature is low, recirculation is
forced off (air drawn in from the outside)
to prevent the windows from misting
up.
In automatic operation, recirculation is
managed automatically by the system
according to outside environmental
conditions.
IMPORTANT It is advisable not to use
the air recirculation function when
the outside temperature is low to
prevent the windows from rapidly
misting up.CLIMATE CONTROL
COMPRESSOR
Press button C to activate/deactivate
the compressor (activation is indicated
by the lit LED on the button). 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 recirculation
to prevent the windows from misting
up and deactivates the AQS function
(for versions/markets, where provided).
In this case, although the climate
control system is capable of
maintaining the required temperature,
the AUTO LED switches off. The
temperatures will flash for a few
seconds if the required temperature
cannot be maintained.
To restore automatic control of
compressor engagement, press again
button C or the AUTO button.
With compressor off:
❒if the outside temperature is higher
than the set one, the system will
not be able to satisfy the request.
The temperature values will then flash
on the display for a few seconds to
indicate this;
❒the fan speed can be reset manually.

GETTING TO KNOW YOUR CAR

With the compressor on and the engine
running, manual ventilation cannot be
lower than the minimum speed (only
one LED lit).
IMPORTANT With the compressor off,
air cannot be introduced to the
passenger compartment with
a temperature lower than the outside
temperature. Moreover, under certain
environmental conditions, windows
could mist up rapidly since the air is not
dehumidified.
RAPID WINDOW
DEMISTING/DEFROSTING
(MAX-DEF function)
Press the
button to activate (LED
on button on) the windscreen and side
windows demisting/defrosting function.
The climate control system carries out
the following operations:
❒switches on the air conditioning
compressor when climatic conditions
are suitable;
❒deactivates air recirculation;
❒sets maximum air temperature (HI) in
both zones;
❒sets fan speed according to the
engine coolant temperature;
❒directs air flow to windscreen and
front side windows diffusers;❒activates the heated rear window.
❒displays the fan speed (LED G lit).
IMPORTANT The MAX-DEF function
remains on for about 3 minutes from
when the engine coolant reaches the
appropriate temperature.
When the function is activated, the LED
on the AUTO button switches off.
With the function activated the only
possible manual adjustments are
adjusting the fan speed and turning the
heated rear window off.
When the B, C,
or AUTO buttons
are pressed, the climate control system
will turn the MAX-DEF off.
HEATED REAR WINDOW
DEMISTING/DEFROSTING
Press the
button to activate (LED
on button on) heated rear window
demisting/defrosting.
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,
press the
button to activate
demisting/defrosting of exterior rear
view mirrors and heated nozzles (for
versions/markets, where provided).IMPORTANT Do not affix stickers to the
inside of the heated rear window over
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, reduces the
temperature in the passenger
compartment relative to the outside
temperature, thus ensuring greater
comfort.
Humidity sensor
(for versions/markets, where provided)
The humidity sensor helps to prevent
the windows from misting up. For
full functionality, it is advisable to
activate the AUTO function (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.

SWITCHING OFF/ON THE
CLIMATE CONTROL
SYSTEM
Switching off the
climate control system
Press the
button (LED on button off).
With climate control off:
❒air recirculation is on, thus isolating
the passenger compartment from
the outside;
❒the compressor is off;
❒the fan is off;
❒the heated rear window can be
switched on or off;
❒the AQS (Air Quality System) function
(for versions/markets, where
provided) cannot be activated.
IMPORTANT The climate control
system control unit stores the
temperatures set before the system
was switched off and restores them
when any button of the system is
pressed (except for button D).Switching on the climate
control system
To switch on the climate control system
in fully automatic mode press the AUTO
button.
START&STOP
Automatic Climate
Control
The dual zone automatic climate control
manages the Start&Stop function
(engine off when the car speed is zero)
to guarantee a suitable comfort inside
the car.
Specifically, the Start&Stop function is
turned off when the weather is
particularly hot or cold to guarantee an
adequate level of comfort 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 function is active
(engine off at zero car speed), the
climate control system will request
restarting of the engine if the inside
temperature conditions rapidly
deteriorate (or if the user requests
maximum cooling – LO – or quick
demisting – MAX DEF).With the Start&Stop function on (engine
off at zero speed), air flow is reduced
to the minimum to maintain comfort
conditions inside the passenger
compartment as long as possible when
the system is in AUTO mode (LED N
on).
The climate control system control unit
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 enhanced by turning
the Start&Stop off by pressing the
dedicated button on the dashboard.
NoteIn particularly severe climate
conditions it is recommended to limit
the use of the Start&Stop function
to prevent the compressor from
continuously switching on and off, with
consequent rapid misting of the
windows and accumulation of humidity
with unpleasant smells in the passenger
compartment.
NoteWhen the Start&Stop function is
on (engine off and vehicle speed zero),
the automatic recirculation
management is turned off always taking
air in from outside, to reduce the
probability of window misting up (as the
compressor is off).

ADDITIONAL HEATER
(for versions/markets, where provided)
This allows the passenger
compartment to be heated more
quickly in cold weather conditions. The
additional heater turns off automatically
after the required comfort conditions
are achieved.
Automatic dual zone
climate control system
(for versions/markets, where provided)
The additional heater activates
automatically depending on the
environmental conditions and with
engine started.
Manual climate control
system
The additional heater activates
automatically when knob A is turned to
the end of the red section and the fan
is set to at least 1
stspeed.
IMPORTANT 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.
IMPORTANT
2) The climate control system
detects the passenger
compartment temperature with a
mean radiant temperature sensor
fitted in a cover under the internal
rear view mirror. Obstructing the
field of view of this sensor with
any object could cause the
climate control system to operate
with less than optimal efficiency
.

“FOLLOW ME HOME”
DEVICE
This device allows you to illuminate the
area in front of the car for a certain
amount of time.Activation
With the key turned to STOP or
removed, pull stalk A towards the
steering wheel within 2 minutes from
when the engine is turned off.
Each time the stalk is moved, the lights
stay on for an extra 30 seconds up to
a maximum of 210 seconds; then
the lights are switched off automatically.
Also, each time the stalk is operated,
the
warning light on the
instrument panel switches on. The
display shows the time set for the
function and the corresponding
graphics.
The warning light comes on when the
lever is operated and stays on until
the function is automatically

AUTOrain sensor activation (for
versions/markets, where
provided) (the windscreen wipers
adapt the operating speed
automatically to suit the intensity
of the rain)
intermittent operation;
continuous slow operation;
continuous fast operation.
Move the stalk upwards (unstable
position) to limit operation to the time
for which the stalk is held in this
position. When released, the stalk will
return to its default position and the
wiper will be automatically stopped.
"Smart washing"
function
Pull the lever towards the steering
wheel (unstable position) to operate the
windscreen washer. Keep the stalk
pulled for more than half a second to
operate the windscreen washer jet and
wiper automatically with a single
movement.
The wiper stops working three strokes
after the stalk is released. A further
stroke after approximately 6 seconds
completes the cycle.RAIN SENSOR
(for versions/markets, where provided)
This is an infrared LED sensor fitted
on the car windscreen fig. 33.
It is able to detect the presence of rain
and consequently manage windscreen
wiping in accordance with the amount
of water on the windscreen.
Activation
The sensor is activated when ring nut A
fig. 32 is turned to “automatic” position
(“AUTO” control): the windscreen wiper
stroke frequency is thus adjusted in
accordance with the amount of water
on the windscreen.
This frequency can vary from no stroke
(no rain - windscreen dry) up to the
2
ndconstant speed operation (heavy
rain - windscreen wet).The sensitivity of the rain sensor can be
adjusted through the Setup menu
(see paragraph “Menu Items” in the
“Knowing the instrument panel”
section).
If the engine is stopped with the lever in
“automatic” position, when it is next
started no wiping cycle will take place
even if it is raining. This prevents
accidental activation of the rain sensor
when the engine is started (e.g. when
the windscreen is being washed by
hand or the wipers are stuck to the
windscreen when there is ice).
To restore automatic operation of the
rain sensor, turn the ring nut on the
right stalk A fig. 32 from automatic
position (AUTO) toOposition and then
turn A ring nut back to the AUTO
position.
When the rain sensor is reactivated
using any of the manoeuvres described
above, reactivation is indicated by a
single stroke of the windscreen wipers,
regardless of the condition of the
windscreen.
If the sensitivity is changed whilst the
rain sensor is operating, a windscreen
wiper stroke is carried out to confirm
the change.

The device cannot be engaged in 1stor
reverse gear: it is advisable to engage
it in 5
thgear or higher.
When travelling downhill with the device
engaged, the car may slightly exceed
the stored speed.
The
warning light and, for
versions/markets, where provided,
message on the display are switched
on to indicate activation.
STORING THE CAR
SPEED
Proceed as follows:
❒turn ring nut A fig. 34 to ON and
press the accelerator to reach the
required speed;
❒move the stalk upwards (+) for at
least 1 second, then release it: the
car speed is now stored and you can
therefore release the accelerator.
If needed (when overtaking for
instance), you can accelerate simply by
pressing the accelerator; when you
release the pedal, the car goes back to
the speed stored previously.RESTORING THE
MEMORISED SPEED
If the device has been disengaged by
pressing the brake or clutch pedal, the
stored speed can be reset as follows:
❒accelerate gradually until a speed
approaching the one stored is
reached;
❒engage the gear selected at the time
that the speed was stored;
❒press the RES button (B fig. 34).
INCREASING THE
MEMORISED SPEED
This can be done in two ways:
❒by pressing the accelerator and
storing the new speed reached
or
❒by moving the stalk upwards (+) until
the new speed, which will be stored
automatically, is reached.
Each movement of the stalk
corresponds to an increase in speed of
about 1 km/h, while keeping the stalk
held upwards will continuously increase
the speed.REDUCING THE
MEMORISED SPEED
This can be done in two ways:
❒by deactivating the device and then
storing the new speed
or
❒by moving the stalk downwards (–)
until the new speed, which will be
stored automatically, is reached.
Each movement of the lever
corresponds to a slight reduction in
speed of about 1 km/h, while keeping
the stalk held downwards will decrease
the speed continuously.
TURNING THE DEVICE
OFF
The device can be deactivated in the
following ways:
❒by turning ring nut A fig. 34 to the
OFF position
❒by switching off the engine;
41

❒by pressing the brake pedal, the
clutch or the accelerator; in this
last case the system is not effectively
deactivated but the system gives
priority to the acceleration request.
The device still remains active,
without the need to press the RES
button to return to the previous
conditions once acceleration
is concluded.
Automatic deactivation
The device deactivates automatically in
the following cases:
❒if the ABS or ESC systems intervene;
❒with the car speed below the set
limit;
❒in the event of system failure.
