❒turn the ring nut C to -or to ®if the windows
do not demist;
❒turn the knob B to the 2ndspeed.
IMPORTANT The climate control system is very useful
for preventing the windows misting up in presence of
high humidity since it dehumidifies the air introduced
into the passenger compartment. IMPORTANT to ensure fast demisting/defrosting, if an
additional heater/air conditioner is present (under the
front or rear seat on Panorama and Combi versions),
if it is activated, turn it off using the button F (LED off)
located on the control panel fig. 51.
After demisting/defrosting, operate the controls to
restore the required comfort conditions.
IMPORTANT The climate control system is very useful
for speeding up the demisting because it dehumidifies the
air. Adjust the controls as described above and press the

IMPORTANT With the compressor off, it is not
possible to introduce air into the passenger
compartment at a temperature lower than that of the
outside air. In certain weather conditions, the windows
could mist up rapidly due to the non-dehumidified air.
The system remembers that the compressor has been
switched off, even after the engine has stopped.
To restore automatic compressor activation control,
press the √button again (in this case, the system will
work only as a heater) or press the AUTO button.
With the compressor switched off, if the outside
temperature is higher than the one set, the system is
not capable of satisfying this request. This is signalled by
the target temperature flashing, after which the word
AUTO goes out.
With the climate control compressor off, the fan speed
can be set to zero manually (no bar shown).
With the compressor enabled and the engine started,
the fan speed may be reduced to the minimum setting
(only one bar shown).

weather conditions are suitable;
❒air recirculation switching-off;
❒sets the maximum temperature for the HI air in both
zones;
❒sets the fan speed set according to the engine
coolant temperature to limit the flow of air that is
insufficiently warm to demist the windows;
❒directs the air flow to the windscreen and front side
windows vents;
❒switches on the heated rear window.
IMPORTANT The rapid demisting/defrosting function
for the windows remains on for about 3 minutes from
when the engine coolant reaches the appropriate
temperature for a rapid demisting of the windows.
When this function is active, the LED on the
corresponding button and the one on the heated rear

SUPPLEMENTARY HEATER
INDEPENDENT
(for markets/versions, where provided)
The vehicle is available, on request, with two different
independent heaters: one fully automatic, the other
which can be programmed.
AUTOMATIC VERSION
The additional heater is turned on in automatic mode
when the engine is started and the required outside
temperature and coolant conditions are present.
Deactivation is always automatic.
IMPORTANT During periods with low outdoor
temperatures when the device cuts in, check that the
fuel level is always higher than the reserve level.
Otherwise the device could lock and require the
assistance of a Fiat Dealership.
The heater burns fuel in the same way
as the engine, though to a lesser extent.
To prevent poisoning and asphyxiation, the
supplementary heater must never be turned on,
even for short periods, in closed environments
such as a garage or workshops without
extraction fans for the exhaust gases.
WARNING
PROGRAMMABLE VERSION
The additional heater operates completely
independently of engine operation and allows the
following:
❒heating the vehicle passenger compartment with the
engine off;
❒defrosting the windows;
❒heating the engine coolant and consequently the
engine itself prior to starting.
The system consists of:
❒a diesel burner to heat the water with an exhaust
silencer for the combustion gases;
❒a metering pump connected to the vehicle tank
pipes, to supply the burner;
❒a heat exchanger connected to the engine cooling
system pipes;
❒a control unit connected to the passenger
compartment heating/ventilation system to allow
automatic operation;
❒an electronic control unit for control and operation
of the burner in the heater;
❒a digital timer A-fig. 55 for turning the heater on
manually or programming the time it comes on.

(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.

changed or deleted by following the above instructions.
Switching the heating system off
Deactivation of the system, depending on the type of
activation (automatic or manual), may be:
❒automatic,at the end of the preset activation time
(60 minutes with lighting of the red display);
❒manualpressing the “immediate heating” button on
the timer again (flame button 1).
In both cases the heating warning light and the display
lighting go out and the passenger compartment heater
unit fan and the combustion stop.
F0N0155mfig. 60
The fluid circulation pump continues to work for
around two minutes to dissipate as much heat as
possible from the heater; the heater can be turned back
on during this stage.
The heater burns fuel in the same way
as the engine, though to a lesser extent.
To prevent poisoning and asphyxiation, the
supplementary heater must never be turned on,
even for short periods, in closed environments
such as a garage or workshops without
extraction fans for the exhaust gases.
WARNING
IMPORTANT When parked the heater switches off
when the battery voltage is low to allow the engine to
be started up.

IMPORTANT Before switching the device on, check
that the fuel level is higher than the reserve level.
Otherwise the device could lock and require the
assistance of a Fiat Dealership.
❒Always turn off the heater when refuelling and near
service stations to avoid the risk of explosion or fire
hazards.
❒Do not park the vehicle on inflammable material
such as paper, grass or dry leaves: fire hazard!
❒The temperature near the heater should not exceed
120 °C (e.g. during stove painting in a body shop).
The electronic control unit components may be
damaged at higher temperatures.
❒Whilst the heater is operating with the engine
switched off, it absorbs energy from the battery; the
engine should therefore be left running for a while to
make sure that the battery is properly recharged.
❒To check the coolant level, follow the instructions in
the “Vehicle maintenance” chapter in the “Engine
coolant system fluid” paragraph. The water in the
heating circuit must contain a minimum percentage
of 10% antifreeze.
❒For maintenance and repairs, only contact Fiat
Dealerships and only use genuine spare parts.
F0N0233mfig. 61
MAINTENANCE
Have the additional heater checked regularly at a Fiat
Dealership (and always at the start of every winter).
This will guarantee safe and economic operation of the
heater as well as a long duration.
ADDITIONAL REAR HEATING
(Panorama and Combi)
(for versions/markets, where provided)
The Panorama and Combi versions have a main heating
system plus an additional one (on request) with the
controls in the roof lining above the second row of
seats, fig. 61.

Unnecessary actions
Avoid accelerating when starting at traffic lights or
before switching off the engine. The latter action, like
doubling the clutch, is unnecessary and causes increase
of consumption and pollution.
Gear selection
Use a higher gear as soon as traffic and road conditions
allow. Using a low gear for faster acceleration will increase
consumption. In the same way improper use of a high gear
increases consumption, emissions an engine wear.
Max. speed
Fuel consumption considerably increases with speed.
Keep your speed as even as possible, avoiding unnecessary
braking and acceleration, which cause excessive fuel
consumption and increased emissions.
Acceleration
Accelerating violently will greatly affect consumption and
emissions: acceleration should therefore be gradual and
should not exceed the maximum torque. Electric devices
Use electric devices only for the amount of time
needed. Rear heated window, additional headlights,
windscreen wipers and heater fan need a considerable
amount of energy, therefore increasing the requirement
of current increases fuel consumption (up to +25% in
the urban cycle).
Climate control system
The climate control system is an additional load which
greatly affects the engine leading to higher consumption
(on average up to +20%). When the temperature
outside the car permits it, use the air vents where
possible.
Devices for aerodynamic control
The use of non-certified devices for aerodynamic
control may adversely affect air drag and consumption
levels.
DRIVING STYLE
Starting
Do not warm the engine with the vehicle at a standstill or
at idle or high speed: under these conditions the engine
warms up much more slowly, increasing consumption and
emissions. It is therefore advisable to move off
immediately, slowly, avoiding high speeds. This way the
engine will warm faster.
