(In winter) the additional heater provides heat,
maintains the temperature and circulates the engine
coolant for the preset time in order to ensure the
optimum temperature conditions of the engine and the
passenger compartment when the engine is started up.
The heater can operate automatically when
programmed with a digital timer or manually by pressing
the “immediate heating” button on the timer.
After heater activation, either programmed or manual,
the electronic control unit operates the liquid
circulation pump and ignites the burner in accordance
with the preset, controlled procedures.
The circulation pump output is also controlled by the
electronic control unit in order to minimise the initial
heating time. When the system operates, the control unit turns on
the passenger compartment heater unit fan at the
second speed.
The thermal power of the boiler is regulated
automatically by the electronic control unit depending
on the temperature of the engine coolant.
IMPORTANT The heater is equipped with a thermal
limiter that cuts off combustion in the case of
overheating due to insufficient coolant/coolant leaks. In
this case, after repairing the fault in the cooling system
and/or topping up the fluid, press the program selection
button before turning the heater back on.
The heater can turn off spontaneously due to misfiring
after start-up or because the flame goes out during
operation. In this case, carry out the turning off
procedure and try to turn the heater back on. If it still
does not work, consult a Fiat Dealership.
Activation of the heating system
When an automatic climate control system is present,
the control unit sets the air temperature and
distribution when the heater is turned on from the park
position. When a manual heater/climate control is
present, to obtain maximum heater efficiency, check
that the passenger compartment heating/ventilation
temperature adjustment knob is in the ‘hot air’ position.
To prioritise passenger compartment pre-heating, set
the air distribution knob to the
©position.

AIRBAG FAILURE (red)
When the key is turned to the MAR-ON
position the warning light comes on but should
go out after a few seconds.
The warning light stays on constantly if there is a failure
in the air bag system.
On some versions the display shows the dedicated
message.
¬
If when turning the key to MAR-ON
the warning light ¬does not turn on
or if it stays on when travelling, there could be
a failure in the safety systems; in this event air
bags or pretensioners may not be deployed in
the event of impact or, in a lower number of
cases, they deploy accidentally. Contact a Fiat
Dealership immediately to have the system
checked.
WARNING
HOT ENGINE COOLANT (red)
When the key is turned to the MAR-ON
position the warning light comes on but should
go out after a few seconds.
The warning light turns on when the engine is
overheated.
ç
If the warning light comes on, proceed as follows:
❒when driving normally: stop the vehicle, switch off
the engine and check that the water level in the
reservoir is not below the MIN mark. If it is not, wait
for a few minutes 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. Also check for any fluid leaks.
If, when restarting, the warning light should come on
again, contact a Fiat Dealership.
❒heavy duty use of vehicle (e.g.: towing trailer uphill
or fully laden car): decrease speed and if the warning
light stays on, stop the vehicle. Wait for 2 or
3 minutes with the engine running and slightly
accelerated to further accelerate the coolant
circulation. Then stop the engine. Check the correct
liquid level as described above.
IMPORTANT Over demanding routes, it is advisable to
keep the engine on and slightly accelerated for a few
minutes before switching it off.
On some versions the display shows the dedicated
message.
