2019 FIAT 500 demist

A - fan knob and climate control system
compressor button.
B - recirculation control / air intake from
outside knob.
C - air distribution knob:
air flow to central and side
dashboard vents to ventilate the
chest and the face in warm
weather;
distribution between feet area
diffusers (warmest air) and
dashboard diffusers (coolest air);
towards the footwell 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 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;
air flow to the windscreen and
front side window diffusers to
demist or defrost them.
D - heated rear windscreen button.
E - temperature adjustment knob.Press the knob A fig. 26 to turn the
climate control system on and off.
NOTE Optimal cooling/heating of the
passenger compartment may not
be guaranteed together with
Start&Stop. To prioritise the operation
of the climate control system,
deactivate the Start&Stop function.
NOTE To stop the air flow from the
vents, turn the knob to 0.
IMPORTANT It is advisable to switch
the air recirculation on whilst queueing
or in tunnels to prevent the introduction
of polluted air. However, it is better
not to use the function for long periods,
particularly if there are many people
on board, to prevent the windows from
misting.
AIR RECIRCULATION
(knob B fig. 26)
internal air recirculation
air intake from outside
Use air recirculation for maximum
climate control performance.
To demist the windows, set the
recirculation control to on
.
IMPORTANT In warm-humid weather
conditions, using cold air on the
windscreen may cause external
condensation, which could limit
visibility.

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
orbuttons are pressed,
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:
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.
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.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/offWARNING
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.

WARNING
143)Modifications or repairs to the electric
system that are not carried out properly
or do not take the system technical
specifications into account can cause
malfunctions leading to the risk of fire.
144)Halogen bulbs contain pressurised
gas, in the case of breakage they may
burst causing glass fragments to be
projected outwards.
145)Only replace the light bulbs when the
engine is off and in a position that does
not interfere with traffic and lets you safely
replace them (see the description in the
“Replacement” paragraph). Also ensure
that the engine is cold, to prevent the risk
of burns.
146)Before replacing the bulb, wait for the
exhaust ducts to cool down: DANGER
OF SCALDING!147)Due to the high power supply voltage,
gas discharge bulbs (Xenon) should only
be replaced by specialised personnel:
danger of death! Contact a Fiat Dealership.
WARNING
49)Halogen bulbs must be handled
holding the metallic part only. Touching the
transparent part of the bulb with your
fingers may reduce the intensity of the
emitted light and even reduce the lifespan
of the bulb. In the event of accidental
contact, wipe the bulb with a cloth
moistened with alcohol and let the bulb
dry.
50)Where possible, it is advisable to have
bulbs changed at a Fiat Dealership. The
correct operation and direction of the
external lights are absolutely essential for
the safety of the car and of compliance
with the law.
51)The intervention must be carried out
taking all precautions necessary to avoid
damaging the bodywork (please use a
sufficiently rigid and appropriately thick
plastic card).
