NOTE:
•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•The use of the Recirculation mode in cold or damp
weather could cause windows to fog on the inside,
because of moisture buildup inside the vehicle. Se-
lect the outside air position for maximum defogging.
•Recirculation can be used in all modes except for
Defrost.
•The A/C can be deselected manually without dis-
turbing the mode control selection.
3. Blower Control
Rotate this control to regulate the amount of air forced
through the ventilation system in any mode. The blower
speed increases as you move the control to the right from
the “0” (OFF) position. There are four blower speeds.
4. A/C Button
Push this button to engage the Air Conditioning. A light
will illuminate when the Air Conditioning system is
engaged.
MAX A/C
For maximum cooling, use the A/C and recirculation
modes at the same time.
ECONOMY MODE
If economy mode is desired, push the A/C button to turn
OFF the indicator light and the A/C compressor. Then,
move the temperature control to the desired temperature.
5. Rear Defrost Control
Push and release the Rear Defrost Control button to turn
ON the rear window defroster and the heated outside
mirrors (if equipped). An indicator will illuminate when
the rear window defroster is ON. The rear window
defroster automatically turns OFF after 20 minutes.

6. Mode Control
Rotate this control to change the system between Modes
(Panel, Bi-Level, Floor, Mix, Defrost).
•Panel
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to direct
airflow.
NOTE:The center instrument panel outlets can be aimed
so that they are directed toward the rear seat passengers
for maximum airflow to the rear.
•Bi-Level
Air is directed through the panel and floor outlets.
•Floor
Air is directed through the floor outlets with a
small amount flowing through the defrost and
side window demister outlets.
•Mix
Air is directed through the floor, defrost, and side
window demister outlets. This setting works best
in cold or snowy conditions that require extra heat
to the windshield. This setting is good for maintaining
comfort while reducing moisture on the windshield.
•Defrost
Air is directed through the windshield and side
window demister outlets. Use this mode with
maximum blower and temperature settings for best
windshield and side window defrosting.
NOTE:The air conditioning compressor operates in Mix
or Defrost, even if the Air Conditioning (A/C) button is
not pushed. This dehumidifies the air to help dry the
windshield. To improve fuel economy, use these modes
only when necessary.

Rear Window Defrosting
Push and release the rear window defrost button to turn
the function on/off.
The activation of the function is indicated by the rear
defrost warning light on the instrument panel switching
on. The function is automatically deactivated after 20
minutes.
If equipped, push the rear defrost button to activate
defrosting of door mirrors and heated rear window.
NOTE: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.
Air Recirculation
Push and release the Air Recirculation button, so that the
LED on the button switch is on, to enter recirculation
mode. 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.
NOTE: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 win-
dows misting.

Air Distribution Selection
Rotate the Mode Control knob to manually select one of
the five possible air distribution settings in the passenger
compartment:
Air flow to the front windshield, front side win-
dow and front/rear footwell diffusers.
Air flow to the front/rear footwell diffusers. This
air distribution allows the passenger compart-
ment to be heated quickly.
Air flow distributed between central and side
dashboard vents and front/rear footwell vents.
Air flow to central/side dashboard vents (passen-
ger ’s body).
Air flow to windshield and side windows.
Selecting the footwell/windshield or only windshield
distribution activates the climate control system com-
pressor (LED on A/C button on) and the air recirculation
is set to#outside air#(LED on Recirculation Control
button off ). This logic guarantees optimum visibility at
the windows. The user can always set air recirculation
and climate control system compressor.

Additional Electric Heater (If Equipped)
The additional electric heater ensures more rapid passen-
ger 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 to 1st speed;
•Temperature Control knob turned completely clock-
wise to red section.
The heater is switched off when at least one of the
conditions above is no longer verified.
NOTE:The 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.
NOTE:The system uses R-1234yf coolant which does not
pollute the environment in the event of accidental leak-
age. Under no circumstances is the use of R-134a allowed.

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 com-
partment and compensates for possible variations in
external climate conditions.

UNDERSTANDING YOUR INSTRUMENT PANEL 199

The climate control system can recognize extremely cold
(or extremely hot) conditions in the passenger compart-
ment and consequently provide optimal management of
the system’s capabilities.
NOTE:The reference temperature is 72° F (22° C) for
optimal comfort management.
The automatically controlled parameters and functions are:
•air temperature 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 operat-
ing 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 pushed or
the system itself intervenes for specific safety reasons.
The amount of air introduced into the passenger com-
partment 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);
