❒a digital timer fig. 54 for turning the
heater on manually or for
programming the time that it comes
on.
The additional heater (during winter)
heats, maintains the temperature
of and circulates engine coolant for
a set time period in order to ensure
optimum engine and passenger
compartment conditions at engine
start-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, whether
programmed or manually, the
electronic control unit operates the
coolant pump and turns on the
burner in accordance with pre-set,
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.
To prioritise windscreen demisting,
set the air distribution knob to
position.
To obtain both functions, set the air
distribution knob to
position.

HILL DESCENT
CONTROL (HDC)
SYSTEM
It is an integral part of the ESC and
is aimed at keeping the vehicle at
a constant speed during a descent,
operating autonomously on the
brakes in various ways at the same
time. In this way the vehicle stability
and completely safe driving are
guaranteed, above all in poor grip
conditions and/or steep descents.
To activate the system reach a
speed slower than 25 km/h and
press the dedicated key A fig. 126;
the LED on the button turns on
and the display gives a specific
message.After reaching the desired speed,
release the accelerator and brake
pedals completely (the LED on
the button flashes). If you want to
increase/decrease the speed, press
the accelerator/brake pedals
again.
IMPORTANT Do not use the device
with the gearbox in neutral position.
IMPORTANT It is important to
engage a gear suitable for the set
speed, to prevent the engine from
stalling.
When this function is active the
brake lights turn on automatically.
While the HDC system is operating
it is also possible to take control
of the vehicle again by pressing the
brake and accelerator pedals.
If the function is not made available
when the button is pressed, this
could be due to brake overheating.
In this case, wait a few minutes
before using the function again.
IMPORTANT The system is
available for speeds below 25
km/h.IMPORTANT Above 25 km/h the
HDC system deactivates but is still
ready to operate (the LED on the
button remains on) when the speed
is again below 25 km/h. If the
speed exceeds 50 km/h, the HDC
system deactivates completely
(the LED on the button switches off)
and the function does not operate
autonomously on the brakes
anymore. To reactivate it, press the
dedicated button again when the
speed is again below 25 km/h.

WARNING
58) The ESC system can’t overrule
the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
59) The ESC system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.

Warning lights on
displayWhat it means What to do
ENGINE COOLANT TEMPERATURE
TOO HIGH
When the key is turned to MAR-ON, the
warning light switches on but should switch
off after a few seconds. The warning light
turns on when the engine is overheated.
The display shows the dedicated message.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, 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. Also check
visually for any fluid leaks. If, when restarting, the
warning light switches on again, contact a Fiat
Dealership.
If the vehicle is used under demanding conditions (e.g.
in high-performance driving): slow down 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 favour the coolant circulation,
then stop the engine. Check the correct coolant 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.
redLOW BATTERY CHARGE
The warning light comes on when the
ignition key is turned to MAR-ON, but it
should go out as soon as the engine has
started (with the engine running at idle
speed a brief delay before going out is
acceptable).If the warning light stays on, contact a Fiat Dealership
immediately.
