2014 FIAT 500L Owners Manual

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 R134a coolant which does not
pollute the environment in the event of accidental leak-
age. 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 com-
partment and compensates for possible variations in
external climate conditions.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 71.6° 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.

UNDERSTANDING YOUR INSTRUMENT PANEL 195

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 pressed 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);
• air distribution to seven positions;
• compressor enablement;
• rapid defrosting/demisting function;
• air recirculation;
• heated rear window;
• system deactivation.

NOTE:The climate control system detects the passenger
compartment temperature using a mean radiant tem-
perature 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 differ-
ent 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 acti-
vation 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 dis-
played) 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 opera-
tion 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
Rotate the Driver Temperature Control, or the Passenger
Temperature Control, dial clockwise or anti clockwise, to
adjust the air temperature in the front left (Driver Tem-
perature Control) or right (Passenger Temperature Con-
trol) zone of the passenger compartment.
The set temperatures are shown on the displays.
Press the SYNC button to align the air temperature
between the two zones.
Turn the Passenger Temperature Control knob to return
to the separate management of air temperatures in the
two zones.
Turning the control knobs completely in one direction or
the other activates theHI(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 the Mode Control buttons (Up/Down/Right
arrows), it is possible to set one of the seven possible air
distributions manually:
•
Up Arrow – Air flow to the windshield and front side
window diffusers to defrost them. Use Defrost mode
with maximum temperature settings for best wind-
shield and side window defrosting. When the defrost
mode is selected, the blower will automatically default
to medium-high.
• Right Arrow – Air flow at central and side dashboard
vents to ventilate the chest and the face during the hot
season.
