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

(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).

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

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.

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

(Panorama and Combi)
(for versions/markets, where provided)
The Panorama and Combi versions
are equipped with a main heating/air
conditioning system plus an additional
system (available on request) with
controls in the roof lining above the
second row of seats fig. 55. Button F
fig. 56 in the control panel must be
enabled for operation; the air
conditioning only works if the main air
conditioner is on.
❒When the knob D is placed in the
fully cold position (control in blue

engine warmed up), from the rear
footwell outlets (located under the
seats in the 2nd and 3rd row for
Panorama versions and the grille on
the left wheel arch side for Combi
versions).❒If the selector knob D is placed in the
intermediate positions, the air will be
distributed between the vents in
the ceiling and the rear footwell
vents, varying the temperature.
IMPORTANT If the compressor on the
main air conditioner control is turned on
(operation of button E), even if the
additional air conditioner fan is in
position 0, the 1st speed will
automatically be activated to prevent
ice formation, with possible damage to
the component.
WARNING
21) The heater burns fuel in the
same way as the engine, though
to a lesser extent. To prevent
poisoning and asphyxiation, the
additional heater must never
be turned on, not even for short
periods, in closed environments
such as a garage or workshops
without extraction fans for the
exhaust gases.22) The heater burns fuel in the

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.60) The capability of the ESC system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise personal safety
and the safety of others.
61) The performance of the ESC and
ASR systems must not encourage
the driver to take unnecessary
risks. Driving style must always be
adapted to road conditions,
visibility and traffic. The driver is,
in any case, responsible for safe
driving.
62) For the ESC and ASR systems to
function correctly, all four tyres
must be the same brand and type,
must be in excellent condition
and, above all, must be of the
prescribed type and size.
63) The HBA system cannot increase
tyre grip on the road over the
limits imposed by laws of physics:
always drive carefully according
to the conditions of the road
surface.
64) The HBA system cannot prevent
accidents, including those due to
excessive speed on bends,
travelling on low-grip surfaces or
aquaplaning.
85

The tyre pressure also increases while
driving the vehicle: this is a normal
condition and does not require any
adjustment of the pressure.
The TPMS continues to advise the
driver of the low tyre pressure condition
until this is corrected; the warning
continues until the pressure
corresponds or exceeds the pressure
prescribed for the cold tyres. When the
tyre low pressure control warning
light
switches on constantly, the
inflation pressure must be adjusted until
it reaches the pressure prescribed for
cold tyres. After the automatic update
of the system, the tyre pressure control
warning light switches off. You may
need to drive the vehicle for about 20
minutes at a speed higher than 20
km/h to allow the TPMS to receive this
information.
NOTE
❒The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
❒Therefore, the TPMS should not be
used as pressure switch while
adjusting the tyre inflation pressure.❒Driving with insufficient tyre pressure
causes their overheating and can
result in tyre failure. The low inflation
pressure reduces fuel efficiency
and tyre tread life and may also affect
handling and braking performance
of the vehicle.
❒The TPMS does not replace the
correct tyre maintenance. It is up to
the driver to maintain the correct tyre
pressure level measuring it with a
suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not
cause the tyre pressure control
warning light to switch on.
❒The TPMS warns the driver of any
condition of insufficient tyre pressure
If this drops below the insufficient
pressure limit for any reason including
low temperature and normal
pressure loss of the tyre.
❒The seasonal temperature changes
affect tyre pressure.
The TPMS uses wireless devices with
electronic sensors mounted on the
wheel rims to constantly monitor the
value of tyre pressure. The sensors
mounted on each wheel as part of the
valve stem transmit various information
of the tyres to the receiver module, in
order to calculate the pressure.WARNING Monitoring and maintaining
the correct pressure in all four tyres
are particularly important.
Tyre pressure
monitoring system low
pressure warnings
The system warns the driver if one or
more tyres are flat by switching on
the warning light
on the instrument
panel (together with a warning message
and an acoustic signal).
In this case, stop the vehicle as soon as
possible, check the inflation pressure
of each tyre and inflate to the cold tyre
pressure value prescribed for the
vehicle. The system will automatically
update and after receiving the tyre
pressure update the tyre pressure
control warning light switches off. You
may need to drive the vehicle for about
20 minutes at a speed higher than 20
km/h to allow the system to receive this
information.
