INTERNAL AIR RECIRCULATION
Press button B (
) so that the LED on the
button switches on. It is advisable to switch internal
air recirculation on while standing in traffic or in
tunnels to prevent the introduction of polluted air.
Do not use the function for a long time, particularly
if there are many passengers on board, to prevent
the windows from misting up.
IMPORTANT Internal air recirculation makes it
possible to reach the required heating or cooling
conditions more quickly depending on the mode
selected. Do not use the internal air recirculation
function on rainy/cold days as it would considerably
increase the possibility of the windows misting.AIR DISTRIBUTION SELECTION
Turn knob F to manually select one of the five
possible air distribution settings in the passenger
compartment:
Air flow to the windscreen, front side window
and front/rear footwell diffusers.Air flow to the front/rear footwell diffusers. This
air distribution allows the passenger
compartment to be heated quickly.Air flow distributed between central and side
dashboard diffusers and front/rear footwell
diffusers.Air flow to central/side dashboard vents
(passenger’s body).Air flow to windscreen and side windows.
Selecting the footwell/windscreen or only windscreen
distribution activates the climate control system
compressor (LED on A/C button on) and the air
recirculation is set to "outside air" (LED on button B
off ). This logic guarantees optimum visibility at the
windows. The user can always set air recirculation
and climate control system compressor.

START&STOP
Manual climate control system
If the Start&Stop function is activated (engine off
when the car speed is zero), the system keeps the air
flow selected by the user.
In these conditions, the passenger compartment
cooling and heating cannot be guaranteed, as the
compressor stops with the engine coolant pump.
The Start&Stop function can be deactivated, to
enhance the operation of the climate control system,
by pressing the dedicated button on the dashboard.
ADDITIONAL ELECTRIC HEATER
(for versions/markets, where provided)
The additional electric heater ensures more rapid
passenger compartment heating.
It activates in cold weather conditions, if the
following conditions are verified:
❒outside temperature low;
❒engine coolant temperature low;
❒engine on;
❒fan speed set at least to 1
stspeed;
❒knob A turned completely clockwise to red
section.The heater is switched off when at least one of the
conditions above is no longer verified.
NoteThe power of the electric heater is modulated
according to the battery voltage.
SYSTEM MAINTENANCE
In winter, the climate control system must be turned
on at least once a month for about 10 minutes.
Have the system inspected at a Fiat Dealership
before the summer.
The system uses R134a coolant which
does not pollute the environment in the
event of accidental leakage. Under no
circumstances use R12 fluid, which is
incompatible with the components of the system.

DESCRIPTION
The automatic dual zone climate control system
regulates the air temperatures in the passenger
compartment in two zones: driver side and
passenger side.
The system maintains comfort inside the passenger
compartment and compensates for possible
variations in external climate conditions.The climate control system can recognise extremely
cold (or extremely hot) conditions in the passenger
compartment and consequently provide optimal
management of the system’s capabilities.
NoteThe reference temperature is 22°C for
optimal comfort management.
The automatically controlled parameters and
functions are:
❒air temperature at the driver/front passenger side
vents;
❒air distribution at the driver/front passenger side
vents;
❒fan speed (continuous variation of the air flow);
❒compressor engagement (for cooling/dehumidifying
the air);
❒air recirculation.
All these functions can be adjusted manually by
operating the system, selecting one or more
functions and modifying their parameters.
Automatic control of the functions will be
suspended: the system will only override the settings
for safety reasons.
Manual selections always take priority over automatic
ones and are stored until the AUTO button is
pressed or the system itself intervenes for specific
safety reasons.

The amount of air introduced into the passenger
compartment is not affected by car speed; it is
regulated by the fan, which is controlled
electronically.
The air temperature is always automatically
controlled according to the temperature set on the
display (except for when the system is off or in
certain conditions when the compressor is
not running).
The system allows the following to be set or adjusted
manually:
❒driver/passenger side air temperature;
❒fan speed (continuous variation);
❒air distribution to 7 positions;
❒compressor enablement;
❒rapid defrosting/demisting function;
❒air recirculation;
❒heated rear window;
❒system deactivation.
The climate control system detects the
passenger compartment temperature
using a mean radiant temperature sensor
located in the interior rear view mirror and
protected by a specific cover. Obstructing the
field of view of this sensor with any object could
cause the climate control system to operate
with less than optimal efficiency.SWITCHING ON THE CLIMATE
CONTROL SYSTEM
The climate control system can be switched on in
different ways: it is advisable to press the AUTO
button and turn the knobs to set the desired
temperatures.
In this way the system operates completely
automatically to adjust the temperature, quantity and
distribution of the air introduced into the passenger
compartment. It also manages the air recirculation
function and the activation of the air conditioning
compressor.
During automatic operation, you can change the set
temperatures, air distribution and fan speed at any
time by using the relevant buttons or knobs: the
system will automatically change the settings to
adjust to the new requirements.
During completely automatic operation (AUTO),
varying the air flow and/or distribution (which are
not displayed) causes the AUTO function LED
to disappear and the system to operate in MANUAL
mode (displaying both the flow and distribution
requested).
When the compressor is deactivated, the AUTO
operation remains active only if the system can
guarantee in-car comfort. Otherwise, the system
switches to MANUAL mode (the set temperatures
will flash on the display). The fan speed is the same in
all the zones of the passenger compartment.

ADJUSTING THE AIR TEMPERATURE
Turn the A or L knob clockwise or anticlockwise to
adjust the air temperature in the front left (knob
A) or right (knob L) zone of the passenger
compartment.
The set temperatures are shown on the displays.
Press the MONO button to align the air
temperature between the two zones.
Turn the L knob to return to the separate
management of air temperatures in the two zones.
Turning the knobs completely in one direction or the
other activates the "HI" (maximum heating) or
"LO" (maximum cooling) functions respectively.
To deactivate these functions, turn the temperature
knob to the desired temperature.
AIR DISTRIBUTION SELECTION
By pressing buttons H (
/
/
), it is possible to
set one of the 7 possible air distributions manually:
Air flow to the windscreen and front side
window diffusers to demist/defrost them.Air flow at central and side dashboard vents to
ventilate the chest and the face during the hot
season.Air flow to the front and rear footwell diffusers.
This air distribution setting heats the passenger
compartment most quickly, giving a prompt
sensation of warmth.
Air flow distributed between footwell
diffusers (hotter air) and central and side
dashboard vents (cooler air). This distribution
setting is useful in spring and autumn on
sunny days.Air flow distributed between footwell
diffusers and windscreen and front side
window defrosting/demisting diffusers. This
distribution setting allows the passenger
compartment to be warmed effectively and
prevents the windows from misting.Air flow distribution between windscreen
demisting/defrosting diffusers and side and
central dashboard vents. This allows air to be
sent to the windscreen in conditions of
strong sunlight.
Air flow distribution to all diffusers on
the car.
NoteAir always flows from the side dashboard
diffusers: it is, however, possible to interrupt the air
flow by operating the wheel located near the
corresponding vents.
In AUTO mode, the climate control system
automatically manages air distribution (the LEDs on
buttons H are off ).
When set manually, the air distribution is indicated
by the LEDs on the selected buttons switching on.

In combined function mode, functions are enabled
together with those already set when the relevant
button is pressed. If a button whose function is
already active is pressed, the operation is cancelled
and the corresponding LED switches off.
To restore automatic control of the air distribution
after a manual selection, press the AUTO button.
ADJUSTING THE FAN SPEED
Turn knob F to increase/decrease the fan speed.
The speed is indicated by the LEDs G on the knob F
switching on.
❒maximum fan speed = all LEDs lit;
❒minimum fan speed = one LED lit.
The fan can only be excluded if the climate control
system compressor has been switched off by pressing
button D.
IMPORTANT To restore automatic control of the fan
speed after a manual adjustment, press the AUTO
button.
AUTO BUTTON
When the AUTO button is pressed (LED on button
lit) the climate control system automatically adjusts
the following settings in the corresponding zones:
❒quantity and distribution of the air introduced into
the passenger compartment
❒climate control system compressor
❒air recirculation
cancelling all previous manual adjustments.This is indicated by the LED on the AUTO button
switching on.
If the AUTO button is pressed when the AUTO LED
is on, the system switches to completely manual
mode; it displays the current flow and distribution
status, which will no longer be managed
automatically.
If a manual intervention is made on at least the air
distribution or on the fan speed, the LED switches
off to indicate that the system is no longer
controlling all functions automatically.
Deactivating the compressor results in the
deactivation of automatic operation only if the
system is no longer able to guarantee comfort
conditions (which depend on the set temperature).
IMPORTANT Should the system no longer be able to
guarantee the required temperature set in various
passenger compartment zones, the set temperature
value will flash for a few seconds on the display.
To restore automatic system control after one or
more manual adjustments, press the AUTO button.
