ENGINE COOLANT TEMPERATURE
GAUGE fig. 14
This shows the temperature of the engine coolant fluid
and starts working when the fluid temperature exceeds
approx. 50 °C.
In normal usage, the needle should hover around the
middle of the scale.
C Low engine coolant temperature.
H High engine coolant temperature.
Warning light B may light up (and a message on the
multifunction display may appear on certain versions) to
indicate that the coolant fluid temperature is too high; in
this case, stop the engine and contact a Fiat Dealership. FUEL GAUGE fig. 13
The needle shows the amount of fuel left in the fuel
tank.
E vacuum tank;
F tank full (see “Refuelling”).
The warning light A coming on indicates that there are
about 10-12 litres of fuel remaining in the tank
(depending on the version). Do not travel with the fuel
tank almost empty: any gaps in fuel delivery could
damage the catalytic converter.
IMPORTANT The needle will point to E and warning
light A will flash to indicate a fault in the system.
Contact a Fiat Dealership to have the system checked.
IMPORTANT It is not advisable to start the additional
heater (Webasto) when fuel is on reserve.

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).
Button for rapid window demisting/
defrosting (D)
When this button is pressed, the climate
control automatically activates all the
functions necessary to speed up the
demising/defrosting of the windscreen
and the side windows:❒turns on the climate control compressor when
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
window button switch on. The message FULL AUTO
goes off on the display.
You can only adjust the fan speed and switch off the
heated rear windscreen manually when this function is
active.
To restore the operating conditions, prior to activation,
simply press button B, air recirculation button G, the
compressor button F or the
AUTO button A.

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.

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.

If, when the ignition key is at MAR-ON the warning light
Yremains on together with warning light m, turn
the key to STOP and then back to MAR-ON; if the
warning lights remain on, try with the other keys
provided with the car.
IMPORTANT If the instrument panel warning light
Ystays on constantly, contact a Fiat Dealership
immediately.
IMPORTANT Never leave the ignition key on MAR-ON
when the engine is off.
The warning light mwill flash for
60 seconds after starting or during
prolonged cranking to indicate a fault with
the glow plug preheating system. Use the vehicle
normally if the engine starts, but contact Fiat
Dealership as soon as possible.
Remember that the brake servo and
power steering are not operational until
the engine has been started, therefore
more effort than usual is required on the brake
pedal and steering wheel.
Avoid jump starting the engine by
pushing, towing or driving downhill.
This could cause a flow of fuel into the
catalytic converter and damage it beyond repair.
HOW TO WARM UP THE ENGINE
AFTER IT HAS JUST STARTED
Proceed as follows:
❒drive off slowly, letting the engine turn at medium
speed. Do not accelerate abruptly;
❒do not demand maximum performance for the first
few kilometres. Wait until the engine coolant gauge
starts moving.STOPPING THE ENGINE
Turn the ignition key to STOP while the engine is idling.
IMPORTANT After a taxing drive, you should allow the
engine to “catch its breath” before turning it off by
letting it idle to allow the temperature in the engine
compartment to fall.
A quick burst on the accelerator before
turning off the engine serves absolutely
no practical purpose, it wastes fuel and is
damaging especially to turbocharged engines.
In some cases, when the engine switches off,
the fan could start for max. 120 seconds.

conditions:
❒trailer or caravan towing;
❒dusty roads;
❒short distances (less than 7-8 km) and with external
temperatures below zero;
❒frequently idling engine or long distance low speed
driving or in the case of long term inactivity;
the following checks must be carried out more often
than indicated in the Scheduled Servicing Plan:
❒check front disc brake pad conditions and wear;
❒check cleanliness of bonnet and boot locks and lever
cleanliness and lubrication;
❒visually inspect the conditions of: engine, gearbox,
transmission, pipes and tubes (exhaust – fuel
– brakes), rubber parts (boots, sleeves, bushes, etc.);
❒check battery charge and liquid level (electrolyte);
❒visual check on various drive belt conditions;
❒check and if necessary change engine oil and oil filter.
PERIODIC CHECKS
Before long journeys, check and, if necessary, restore:
❒engine coolant fluid level;
❒brake fluid level;
❒windscreen washer fluid level;
