Fiat 500 Owner's Handbook Manual page 28

A - Climate control system
compressor on/off.
B - Adjustment of temperature
inside the passenger compartment.
: increase required temperature to
the HI value (maximum heating).
: increase required temperature to
the LO value (maximum cooling).
C - fan speed adjustment.
When the or
the fan speed, increases or decreases
as shown by the bars on the display
lighting.
D - Button for switching fast front
window demisting/defrosting on
and off.
IMPORTANT The function remains
active for approximately 3 minutes after
the coolant temperature exceeds 50°C.
IMPORTANT In warm-humid weather
conditions, using cold air on the
windscreen may cause external
condensation, which could limit
visibility.
E - Passenger compartment air
distribution.
By pressing the buttons, one of the five
possible air flow distribution patterns
can be selected:
26
buttons are pressed,
F - Heated rear windscreen on/off
button.
IMPORTANT Do not apply stickers on
the inside of the rear window over
the heating filaments to avoid damage.
air flow to the windscreen and front
side window diffusers to demist
or defrost them.
air flow to central and side
dashboard vents to ventilate the
chest and the face during the hot
season.
air flow to the front seat feet area
diffusers. Due to the natural
tendency of heat to spread
upwards, this type of distribution
warms the passenger
compartment up as quickly as
possible, providing an immediate
feeling of warmth.
+ distribution between feet area
diffusers (warmest air) and
dashboard diffusers (coolest
air).
+ distribution between footwell
diffusers and windscreen/
front side window vents. This
type of distribution achieves
effective heating of the
passenger compartment and
prevents the windows from
misting up.
G - Switching off
H - Internal air recirculation on/off
button
It is advisable to switch the internal air
recirculation on whilst queuing or in
tunnels to prevent the introduction of
polluted air.
LED on button ON = recirculation ON.
LED on button OFF = recirculation OFF.
IMPORTANT It is inadvisable to use
air recirculation when the outside
temperature is low, since the windows
could mist rapidly.
I - Automatic climate control
system on/off
WARNING
2) The system uses R1234yf coolant,
which is compatible with the laws in force
in the countries where the vehicle is sold.
When charging, only use the gas indicated
on the dedicated plate in the engine
compartment . The use of other coolants
affects the efficiency and condition of
the system. The lubricant used for the
compressor is also strictly linked to the
type of cooling gas, please refer to a Fiat
Dealership.
