Air recirculation on/off
button (G)
The air recirculation is managed
according to the following operating
logic:
❒override on (inside air recirculation
always on), indicated by the LED
on button G and the
symbol on
the display;
❒override off (air recirculation
constantly off with air intake from the
outside), signalled by the LED in
the button switching off and by the
symbol in the display
disappearing.
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.
It is however inadvisable to use it on
rainy/cold days as it would considerably
increase the possibility of the windows
misting inside, especially if the climate
control compressor is off.
To prevent the windows from misting
up, the recirculation is forced off (i.e. air
is drawn in from the outside) when
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
enablement/off button
(F)
Press button
to switch the climate
control compressor off (if on). The icon
on the display will go 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 windows from misting up.
Although the system is capable
of maintaining the required
temperature, the word FULL will
disappear from the display. If, on the
other hand, it is no longer capable
of maintaining the temperature, the
letters flash and the word AUTO goes
out.IMPORTANT With the compressor off, it
is not possible to introduce air cooler
than ambient temperature into the
passenger compartment. Furthermore,
in certain conditions, the windows
could mist up rapidly because the air is
not dehumidified.
The system remembers that the
compressor has been switched off,
even after the engine has stopped.
To restore automatic compressor
control, press the
button again (in
this case, the system will only work 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)
Press this button and the climate
control system will automatically switch
on all the functions required for fast
windscreen and side window
demisting/defrosting:
❒switches on climate control
compressor when climatic conditions
are suitable;
❒switches air recirculation off;
❒maximum air temperature HI in both
areas;
❒sets the fan speed according to the
engine coolant temperature to limit
the flow of air that is not sufficiently
warm to demist the windows;
❒directs air flow to windscreen and
front side windows vents;
❒heated rear window on.
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 window
manually when this function is active.
To restore the previous operating
conditions, simply press button B, air
recirculation button G, compressor
button F or AUTO button A.
NoteTo guarantee rapid demisting/
defrosting, if an additional heater/air
conditioner is present (under the front
or rear seat on Panorama and Combi
versions), if activated, deactivate it
using button F (LED off) located
in control panel F fig. 55.Switching the system
OFF (E)
Press button E to switch the climate
control system off. The display will go
out.
The following climate control conditions
will be present when the system is off:
❒display off;
❒temperature setting not displayed;
❒air recirculation on, thereby insulating
the passenger compartment from the
outside (recirculation LED on);
❒climate control compressor off;
❒fan off.

ADDITIONAL
HEATER
(for versions/markets, where provided)
On some versions, an additional heater
is also present beneath the driver's
seat. The fan for this heater is operated
by means of the button F located on
the control panel fig. 53.
INDEPENDENT
ADDITIONAL
HEATER
(for versions/markets, 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.
21)
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.PROGRAMMABLE
VERSION
The additional heater operates
completely independently of engine
operation and allows the following:
❒heating the passenger compartment
with the engine off
❒defrosting the windows;
❒heat the engine coolant and then the
engine itself prior to starting.
The system consists of:
❒a diesel burner for heating the water
with an exhaust silencer for the
combustion gases;
❒a metering pump connected to the
reservoir pipes for supplying 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
controlling and adjusting the built-in
burner;
❒a digital timer fig. 54 for turning the
heater on manually or for
programming the time that it comes
on.
MODEF
53F1A0305
41

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.

system off
Deactivation of the system, depending
on the type of activation (automatic
or manual), may be:
❒automaticwhen the programmed
duration is over; when the set time
is over, the display switches off.
❒manualpressing the “immediate
heating” button on the timer again
(flame button 6).
In both cases, the heating warning light,
the display lighting and the passenger
compartment heater fan go off and
burning stops.
The fluid circulation pump continues to
work for around two minutes to
dissipate as much heat as possible; the
heater can be turned back on during
this stage.
22)
IMPORTANT The parking heater goes
off when battery voltage is low to allow
the vehicle to be started.
IMPORTANT Before turning on the
device, ensure that the fuel level is
above the reserve. 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
oven 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.
45

❒To check the coolant level, follow the
instructions in the "Vehicle
maintenance" chapter, "Engine
coolant system fluid" paragraph. The
water in the heating circuit must
contain a minimum percentage of
10% antifreeze.
❒For maintenance and repairs, consult
only a Fiat Dealership and use only
original parts.
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
are equipped with a main heating
system plus an additional system
