START&STOP SYSTEM
CONTROL
The dual zone automatic climate control
manages the Start&Stop system
(engine off and vehicle at a standstill) in
order to guarantee sufficient comfort
inside the passenger compartment.
IMPORTANT In particularly severe
climate conditions it is recommended to
limit the use of the Start&Stop 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.
IMPORTANT When the Start&Stop
system is on (engine off and car 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).
WARNING
19)It is inadvisable to use internal air
recirculation when the outside temperature
is low, since the windows could mist up
rapidly.
WARNING
5)The climate control system detects the
passenger compartment temperature
using a mean radiant temperature 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.
CLIMATE CONTROL
SYSTEM
The system uses a coolant that is
compatible with the laws in force in the
countries where the vehicle is sold,
R134a or R1234yf. When charging,
only use the gas indicated on the
dedicated plate in the engine
compartment fig. 26.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: contact a Fiat Dealership.

Warning light What it means
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light turns on when the engine is overheated. On some versions the display shows the
dedicated message.
In normal driving conditions: stop the car, switch off the engine and check that the water level in the
reservoir is not below the MIN mark. In this case, wait for the engine to cool down, then slowly and
carefully open the cap, top up with coolant and check that the level is between the MIN and MAX marks on
the reservoir itself. Also check visually for any fluid leaks. If, when restarting, the warning light (or display
symbol) switches on again, contact a Fiat Dealership.
If the car is used under demanding conditions (e.g. in high-performance driving):slow down and, if
the warning light stays on, stop the car. Wait for 2 or 3 minutes with the engine running and slightly
accelerated to further favour the coolant circulation. Then stop the engine. Check that the coolant level is
correct as described above.
IMPORTANT On demanding routes, it is advisable to keep the engine on and slightly accelerated for a few
minutes before stopping it.
