Air distribution buttons (B)
Press these buttons to manually set one
of the seven air distribution settings:
▲Air flow to the windscreen and front side window
vents to demist or defrost the windows.
˙Air flow to the central and side dashboard vents to
ventilate the chest and the face in hot weather.
▼Air flow to the front and rear footwell vents. Thanks
to the natural tendency of hot air to rise, this
distribution pattern allows the passenger
compartment to warm up as quickly as possible,
providing an immediate feeling of warmth.
˙
▼Air flow distribution split between footwell vents
(hotter air) and central and side dashboard vents
(cooler air). This distribution mode is particularly
useful in spring and autumn on sunny days.
▲
▼Air flow distribution split between the footwell vents
and the windscreen and front side windows
defrosting/demisting vents. This allows an adequate
warming of the passenger compartment and
prevents the windows from steaming up.
This function may be used to heat up the passenger
compartment by exploiting the system’s potential to the
full. In this event, the system stops controlling the
temperature automatically and sets the air mixing to
maximum heating. The air speed and distribution are
fixed.
In particular, if the heating fluid is not sufficiently hot,
the maximum fan speed does not come on straight away
in order to limit the intake of insufficiently hot air to the
passenger compartment.
All manual settings will be allowed when this function
is on.
To switch the function off, simply turn the temperature
knob anticlockwise and set the required temperature.
❒LO function (maximum cooling):
select by turning the temperature knob anticlockwise
beyond the minimum value (16 °C).
This function may be used to cool down the passenger
compartment by exploiting the system’s potential to the
full. In this event, the system stops controlling the
temperature automatically and sets the air mixing to
maximum cooling. The air speed and distribution are
fixed. All manual settings will be allowed when this
function is on.
To switch the function off, simply turn the temperature
knob clockwise and set the required temperature.

It is however not advised to use it on rainy/cold days as
it would considerably increase the possibility of the
windows steaming up, especially if the climate control
compressor is off.
To prevent steaming up, the recirculation is forced off
(i.e. air is introduced from the outside) when the the
outside temperature is cold.
It is advisable not to use the air recirculation function
when the outside temperature is low to prevent the
windows from rapidly misting up.
Climate control compressor on/off
button (F)
Pressing the √button switches the
climate control compressor off, it if was
on previously and the logo in the display
goes out.
Press the button when the LED is off to restore
automatic system control of compressor activation.
The icon will light up on the display.
The system will switch recirculation off when the
compressor is switched off to prevent misting up.
Although the system is capable of maintaining the
required temperature, the word FULL will disappear
from the display. If the system is no longer able to
maintain the temperature, the figures will flash and the
word AUTO will go out. IMPORTANT Should the system (after manual
intervention) no longer be able to guarantee the target
temperature for the passenger compartment, the set
temperature value will start flashing to indicate the
difficulties the system is experiencing and then the word
AUTO will go out.
To restore system automatic control at any time, after
one or more manual adjustments, press the AUTO
button.
Air recirculation on/off button (G)
The Air recirculation works according to
the following operating logics:
❒override on (air recirculation always on), indicated
by the LED on the button
Gcoming on and the
symbol íon the display;
❒override off (air recirculation always off and
introduction of outside air), indicated by the LED
on the button going off and the symbol êappearing
on the display.
These operating conditions are obtained by pressing air
recirculation button G in sequence.
IMPORTANT The engagement of the air recirculation
system makes it possible to reach the required heating
or cooling conditions faster.

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. 61 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. 67
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

PRETENSIONERS
To increase the efficiency of the seat belts, the vehicle is
fitted with pretensioners. These devices, in the event of
a violent frontal impact, rewind the seat belts a few
centimetres. In this way they ensure that the seat belt
adheres perfectly to the wearer before the restraining
action begins.
The buckle moves downwards to indicate that the
device has intervened; the seat belt cannot be drawn
back up even when guiding it manually.
IMPORTANT To obtain the highest degree of
protection from the action of the pretensioning device,
wear the seat belt keeping it tight to the chest and
pelvis.
A slight amount of smoke may be detected during
operation of the pretensioners. This smoke is not
harmful and does not indicate a fire.
The pretensioner does not require any maintenance or
lubrication.
Anything that modifies its original conditions invalidates
its efficiency.
If unusual natural events (floods, sea storms, etc.) have
caused the device to be contaminated by water and
mud, it must be replaced.The pretensioner can only be used once.
After it is triggered, have it replaced at
a Fiat Dealership. The device expiry date is
shown on the plate in the glove compartment:
contact the FIAT Dealership when it is time to
replace the device.
WARNING
Operations which lead to knocks,
vibrations or localised heating (over
100 °C for a maximum of 6 hours) in the
area around the pretensioners may cause
damage or trigger them. These devices are not
affected by vibrations caused by irregularities of
the road surface or low obstacles such as kerbs,
etc. Contact a Fiat Dealership for any assistance.
LOAD LIMITERS
To increase passenger safety, the front seat belt reels
contain a load limiter which allows controlled sag in
such a way as to dose the force acting on the chest and
shoulders during the belt restraining action in the event
of frontal impact.
