Turning the knobs fully clockwise or
counter-clockwise until they reach the ex-
treme selections HI or LO, the maximum
heating or cooling functions are respec-
tively engaged:
❒HI function (highest heating power):
this is turned on by rotating the temper-
ature knob clockwise and passing the max.
temperature value (32°C). It can be acti-
vated independently from driver or front
passenger side or both (also when the
MONOfunction is selected).
When this function is on, the display
shows HI.
This function can be engaged when re-
quiring to heat the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system. This
function uses the maximum temperature
of the coolant fluid, while air distribution
and fan speed are controlled according to
the system settings.
More particularly, max. fan speed will not
be immediately engaged if coolant is not
hot enough; this to prevent admitting air
that is not warm enough to the passenger
compartment.
All manual settings are possible with this
function on.To switch the function off, simply turn the
knob counter-clockwise and set the re-
quired temperature.
❒LOfunction (highest cooling power):
this is turned on by rotating the temper-
ature knob counter-clockwise and passing
the min. temperature value (16°C). It can
be activated independently from driver or
front passenger side or both (also when
the MONOfunction is selected).
When this function is on, the display
shows LO.
This function can be engaged when re-
quiring to cool the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system. This
function activates automatically:
❒MONOfunction;
❒air distribution at central / side vents
(shown by the relevant symbol on the
display);
❒fan at max. speed;
❒climate control compressor.
All manual settings are possible with this
function on.
To switch the function off, simply turn the
knob clockwise and set the required tem-
perature.Front air distribution buttons B-F
Pressing these buttons it is possible to
choose manually one of the seven possi-
ble air distributions to the passenger com-
partment (right or left side):
▲Air flow to the windscreen and front
side window vents to demist or de-
frost them.
˙Air flow at central and side dash-
board vents to ventilate the chest
and the face during the hot season.
▼Air flow towards the front and rear
lower parts of the passenger com-
partment. Due to the natural ten-
dency of heat to spread upwards,
this type of distribution allows heat-
ing of the passenger compartment
in the shortest time, also giving a
prompt feeling of warmth.
˙
▼Splitting of the air flow between the
vents to the lower part of the pas-
senger compartment (warmest air)
and the dashboard centre and side
outlets (coolest air). This air flow
distribution is particularly useful in
spring and autumn when the sun is
shining.

automatically adjusts the amount and dis-
tribution of the air admitted to the pas-
senger compartment, cancelling all the
previous manual adjustments.
This condition is indicated by the message
FULL AUTOon the front system dis-
play.
Manual operation of at least one automatic
function (air recirculation, air distribution,
fan speed or climate control compressor
off) will cause FULL message going off the
display. This means that automatic control
is not complete (except temperature con-
trol which is always automatic).IMPORTANT Should the system (after
manual settings) be no longer able to guar-
antee the required temperature set in the
passenger compartment, the set tempera-
ture value will start flashing to indicate this
condition, after one minute the AUTO
message will turn off.
To restore system automatic control at
any time, after one or more manual ad-
justments, press button AUTO.

side with that on the driver side, it is there-
fore possible to set the same temperature
and air distribution between the two zones
by turning the knob on driver side. This
function is provided to simplify tempera-
ture adjustment of the whole passenger
compartment when only the driver is on-
board. Separate operation of set temper-
ature and air distribution is restored by
turning knob Por G(to set temperature
on front passenger side) or by pressing
again button MONO, when the wording

Air recirculation and AQS function
on/off button A
If the AQSsensor is not fitted, air recir-
culation works according to the following
operating logics:
❒forced switching on (inside air recir-
culation always on), indicated by sym-
bol íon the display;
❒forced switching off (air recirculation
always off with air inlet from the out-
side), indicated by symbol
êon the
display.
The above operating conditions are ob-
tained by pressing in sequence the air re-
circulation button A.
Due to safety reasons, after long recircu-
lation activation (over 25 minutes), the
system will deactivate automatically air re-
circulation for 60 seconds to enable out-
side air inlet.
IMPORTANT The inside air recirculation
system makes it possible to reach the re-
quired heating or cooling conditions faster. It is however inadvisable to use it on
rainy/cold days as it would considerably in-
crease the possibility of the windows mist-
ing inside, especially if the climate control
system is off.
When outside temperature is below 3°C,
recirculation is forced to off (outside air
inlet) to prevent window misting up.
It will be reactivated automatically if out-
side temperature becomes higher than 5
°C.
The AQSsensor (Air Quality System) in
addition to the above operating logics, en-
ables to control recirculation automati-
cally according to the quality of outside air:
❒automatic control indicated by symbol
≥on the display.
In this event the display will show symbol
ïor ñaccording to actual recircu-
lation operating conditions (on or off).
In automatic operation with AQS,inside
air recirculation is turned on automatical-
ly when the antipollution sensor detectsthe presence of polluted air, for example
when driving in the city, queues and tun-
nels.
With compressor on, in order to prevent
polluted air (exhaust gas) inlet at stops, the
system will stop air recirculation when the
car speed falls below 6 km/h. As the car
speed increases (over 25 km/h), the sys-
tem will restore the previous automatic
operating conditions.
In automatic operation, AQSis deacti-
vated when outside temperature is below
3°C, the system will activate air recircu-
lation (indicated by symbol ≥on the
display). The user can however set it man-
ually by operating in rolling mode the reir-
culation button: pressing the button for
the first time will display the current re-
circulation condition, indicated by symbol
ê.
It will be reactivated automatically if out-
side temperature becomes higher than 5
°C.
Press the button again to select the re-
quired recirculation condition, indicated
by the corresponding symbol on the dis-
play. Under these conditions manual ac-
tivation of the AQSfunction could cause
window misting up.
When air recirculation is set manually,
wording FULLwill turn off and A will dis-
appear from the recirculation symbol on
the display.
It is inadvisable to use the in-
side air recirculation func-
tion with low outside temperature as
windows may mist over quickly.

IMPORTANT NOTES ABOUT
THE T.P.M.S. SYSTEM
Failure indications will not be stored and
therefore will not be displayed when turn-
ing the engine off and on again. If failure
persists, the control unit will send warn-
ing indications to the instrument panel on-
ly after a few seconds when the car is
moving.
IMPORTANT T.P.M.S. system cannot in-
dicate sudden tyre pressure drops (e.g.:
tyre burst). In this event, brake the car
cautiously and avoid sudden steering.
IMPORTANT Replacing standard tyres
with winter tyres and vice versa involves
T.P.M.S. system set-up that shall be per-
formed at Fiat Dealerships only.
IMPORTANT The T.P.M.S. system re-
quires special equipment. Consult Fiat
Dealership to know what type of acces-
sories are compatible with the system
(wheels, wheel caps, etc.). Using other ac-
cessories could cause system malfunc-
tioning.IMPORTANT Tyre pressure could change
according to outside temperature. For this
reason the T.P.M.S. system could tem-
porarily indicate low tyre pressure. In this
event check pressure with cold tyres and
restore proper inflation values if required.
IMPORTANT If the car is fitted with
T.P.M.S. system, tyre and/or rim removal
and refitting operations involve special
precautions; to prevent damages or wrong
sensor refitting, contact Fiat Dealership to
have tyre and/or rim changed.
IMPORTANT If the car is fitted with
T.P.M.S. system, when changing a tyre,
change also the rubber seal of the valve.
Contact a Fiat Dealership.
IMPORTANT Strong radiofrequency
noise may inhibit regular TPMS system op-
eration; in this event, a dedicated message
will be displayed to warn the driver. This
message will disappear automatically as
soon as noise disappears.SOUND SYSTEM

MULTIJET ENGINES
If the outside temperature is very low, the
diesel thickens due to the formation of
paraffins and could clog the diesel fuel fil-
ter.
In order to avoid these problems, different
types of diesel are distributed according to
the season: summer type, winter type and
arctic type (cold, mountain areas).
If refuelling with diesel fuel not suitable for
the current temperature, mix diesel fuel
with DIESEL MIX additive in the propor-
tions stated on the can, putting first the
antifreeze in the tank and then the diesel
fuel.FUEL FILLER CAP fig. 124
The fuel filler cap lock is automatically con-
trolled by the central door lock.
In an emergency (e.g.: electric system fail-
ure) it is possible to unlock it by pulling
string B. To find the string, remove the
right-hand side cover A.
To carry out fuelling, open flap C-fig. 125
and unscrew cap D; the cap is fitted with
an antiloss device Ewhich fastens it to the
flap so it cannot be mislaid.
The sealing of the tank may cause light
pressurising in the tank. A little breathing
off, while slackening the cap, is absolutely
normal. The car must only be filled
with diesel fuel for motor ve-
hicles, in compliance with Eu-
ropean Standard EN590. The
use of other products or mixtures may
irreparably damage the engine with in-
validation of the warranty due to the
damage caused. In the event of acci-
dentally filling with another type of fu-
el, do not start the engine and empty
the tank. If the engine has been run
even for only a very short time, in ad-
dition to the tank, it is also necessary
to drain out the whole fuel circuit.
fig. 124F0L0137m
REFUELLING
To guarantee full tank filling, carry out two
refuelling operations after the first click of
the fuel delivery gun. Avoid further top-
ping up operations that could cause dam-
ages to the fuel system.

DIESEL PARTICULATE FILTER
(DPF)
The Diesel Particulate Filter is a mechan-
ical filter, integral with the exhaust system,
that physically traps particulates present
in the exhaust gases of Diesel engines.
The diesel particular filter has been adopt-
ed to eliminate almost totally particulates
in compliance with current / future law
regulations.
During normal use of the car, the engine
control unit records a set of data (e.g.:
travel time, type of route, temperatures,
etc.) and it will then calculate how much
particulates has been trapped by the filter.Since this filter physically traps particulates,
it shall be cleaned (reclaimed) at regular
intervals by burning carbon particles.
Reclaiming procedure is controlled auto-
matically by the engine control unit ac-
cording to the filter conditions and the
conditions of use of the car.During reclaiming the following phenom-
ena could take place: idling slight increase,
fan activation, slight smoke increase, high
exhaust temperatures. These situations
shall not be considered as faults and they
do not affect car performance and envi-
ronment.
If the dedicated message is displayed, re-
fer to section “Warning lights and mes-
sages”.
