+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.
IMPORTANT In warm-humid weather conditions, using cold air on the windscreen may cause external condensation, which
could limit visibility.
E - Turns on/off the MAX-DEF function (fast front window defrosting/demisting).
F - Turns on/off the air conditioning compressor.
G - Turns on/off the internal air recirculation.
H - Turns on/off the air conditioning.
F - Turns on/off the heated rear window and (for versions/markets, where available) the heated mirrors/heated windscreen.
L/M - Adjusts the fan speed.
The automatic climate control manages the Start&Stop function (engine off when the car speed is zero) to guarantee a suitable
comfort inside the passenger compartment.
NOTE In particularly severe climate conditions it is recommended to limit the use of the Start&Stop function to prevent the
compressor from continuously switching on and off, with consequent rapid misting of the windows and accumulation of
humidity with unpleasant smells in the passenger compartment.
WARNING
18)It is advisable not to use the internal air recirculation function when the outside temperature is low, because the windows could mist
rapidly.
WARNING
2)The system uses a coolant that is compatible with the laws in force in countries where the vehicle is sold, R134a or R1234yf. In case of a
recharge operation, only use the gas indicated on the label placed 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.
