9 - internal air recirculation on/off button;
10 - AUTO function activation button (automatic operation).
Stop/Start
(where provided)
The automatic climate control system manages the Stop&Start system (engine off when vehicle speed is equal to 0 km/h) to
ensure adequate comfort inside the vehicle.
In particular, the climate control system deactivates the Stop/Start if:
the climate control system is in AUTO mode (LED on the button switched on) and the temperature conditions inside the
vehicle are far from a comfort temperature;
the climate control system is in MAX A/C;
the climate control system is in the MAX-DEF status.
When the Stop&Start system is active (engine off and vehicle speed equal to 0 km/h), the climate control system will request
restarting of the engine if the inside temperature conditions rapidly deteriorate (or if the user requests maximum cooling – MAX
A/C – or quick demisting – MAX-DEF).
With the Stop&Start system on (engine off and vehicle speed equal to 0 km/h), the flow is reduced as much as possible, to
keep the compartment comfort conditions for longer.
The climate control system control unit attempts to manage the decreased comfort caused by stopping the engine as far as
possible (switching off the compressor and engine coolant pump). It is anyway possible to prioritise the operation of the climate
control system, deactivating the Stop/Start system by pressing the
button, located on the central dashboard panel.
NOTE In particularly severe climate conditions it is recommended to limit the use of the Stop&Start system 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.
NOTE When the Stop&Start system is on (engine off and vehicle at a standstill), the automatic recirculation management is
turned off always taking air in from outside, to reduce the probability of the windows misting up (as the compressor is off).
IMPORTANT
1) 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.
