LOOKING AFTER THE SYSTEM
Run the climate control system for at least
10 minutes every month during the win-
ter. Have the system inspected at a Fiat
Dealership before the summer.
The system uses R134a re-
frigerant fluid which does not
harm the environment in the
event of accidental leakage.
Never use R12 fluid which is not com-
patible with the system components.IMPORTANT The inside air recirculation
system makes it possible to reach the re-
quired “heating” or “cooling”
conditions
faster.
Do not use the air recirculation function
on rainy/cold days as it would
consider-
ably increase the possibility of the win-
dows misting inside. AIR RECIRCULATION
Move slider Dto position to switch
internal air recirculation on.
It is advisable to switch internal air
recir-
culation on while standing in queues or in
tunnels to prevent the introduction of pol-
luted air. Do not use the function for a
long time,
particularly if there are many
occupants on board, to prevent the win-
dows from misting up.

AUTOMATIC CLIMATE
CONTROL SYSTEM
(where provided)
GENERAL
The automatic climate control system ad-
justs the temperature, the quantity and the
distribution of the air in the
passenger
compartment. Temperature is controlled
on the basis of an
“equivalent tempera-
ture” principle; in other words, the sys-
tem continuously works to keep the com-
fort level inside the car constant and
to
compensate for possible variations of ex-
ternal conditions, including sun radiation
detected by a specific sensor.The automatically controlled parameters
and functions are:
air temperature at the vents;
air distribution at the vents;
fan speed (continuous air flow varia-
tion);
compressor fan on (for cooling/dehu-
midifying the air);
air recirculation.All functions may be manually changed.
In
order words, you may select one or more
functions and change the parameters as
required. Automatic control of the man-
ually changed functions will be suspended:
the system will change override your set-
tings only for safety related reasons (e.g.
risk of misting up).
Manual selections will always have higher
priority over automatic settings and will
be stored until the user switches the sys-
tem back to automatic control by press-
ing AUTOexpect for the cases in which
the system will int ervene for particular,
safety-related reasons.
You can adjust one function automatical-
ly and have the automatic system control
all the others.
The air temperature is always automati-
cally controlled according to the temper-
ature shown on the display (except for
when the system is off or in certain con-
ditions when the compressor is not run-
ning).

USING THE CLIMATE
CONTROL SYSTEM
The system can be started in different
ways,
but it is advisable to start by press-
ing the AUTObutton and then turning
the knobs to set the temperature required
on the display.
The system will start running automatically
in this way and the set comfortable tem-
perature will be reached as quickly as pos-
sible. The system will adjust the temper-
ature, the quantity and the distribution of
the air introduced into the passenger com-
partment and will manage the recircula-
tion function and the compressor.
Manual intervention is only required for
the following functions during fully auto-
matic operation.
air recirculation, to keep the
function always either on or off;
to speed up demisting/defrosting of
windscreen, rear window and exter-
nal rearview mirrors;During completely automatic system op-
eration, you can vary the set temperature,
the air distribution and the fan speed us-
ing the corresponding buttons or knobs
at any time: the system will automatically
change settings to adapt to the new re-
quest.
During fully automatic operation (FULL
AUTO), the word FULLwill disappear
if the air distribution, air speed,
compres-
sor and/or recirculatio n settin gs are
changed. In this way, the functions will
switch from automatic to manual control
until AUTOis pressed again. With on or
more manually set functions, the intro-
duced air temperature is still managed au-
tomatically by the system, except for when
the compressor is off: in the case,
the air
introduced into the passenger compart-
ment cannot be cooler than the outside
air.Air temperature adjustment
knob (I)
Turn the knob either clockwise or anti-
clockwise to increase or lower the re-
quested temperature in the
passenger
compartment. The set temperature is
shown on the display.
Turn the knob either all to the right
or
all to the left to the extreme HIor LO
position to use the maximum heating or
maximum cooling functions:
HI function (maximum heating):
select by turning the temperature knob
clockwise over the maximum value
(32 °C).
This function may be used to heat up the
passenger compartment exploiting the
system potential to the maximum. In this
condition, the system stop controlling
temperature automatically and sets air
mixing to maximum heating. The air speed
and distribution are fixed.
Specifically,
if the heating fluid is not suffi-
ciently warm, the fan will not start up at
the maximum speed immediately to limit
introducing excessively cool air into 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.
LOfunction (maximum cooling):
select by turning the temperature knob
anticlockwise under the minimum value
(16 °C).
This function may be used to cool down
the passenger compartment exploiting the

condition,
the system stop controlling
temperature automatically and sets air
mixing to maximum cooling. The air speed
and distribution are fixed. All manual set-
tings will be allowed when this function
is on.
To switch the function off, simply turn the
temperature knob anticlockwise and set
the required temperature.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 de-
frost them.
Air flow at central and side dashboard
vents to ventilate the chest and
the
face during the hot season.
Air flow to the front and rear foot well
vents. Thanks to the natural tenden-
cy of hot air to spread upwards,
this
distr ibution pattern allows to warm
the passenger compartm ent up as
quickly as possible,
providing an im-
mediate feeling of warmth.
Air flow distributed between foot well
vents (hotter air) and central and side
dashboard vents (cooler air). This dis-
tribution is particularly useful in spring
and autumn on a sunny day.
Air flow distributed between foot well
vents and windscreen and front side
window defrostin g/demistin g vents.
This allows an adequate warming of
the passenger compartment and pre-
vents the windows from misting up.
Air flow distr ibuted between wind-
screen and front side window de-
froster/demister and central and side
dashboard vents.
This distribution al-
lows to maintain good levels of com-
fort and the passenger compartment
adequately cool (summer).
Air flow distributed between wind-
screen and front side window de-
froster/demister and central and side
dashboard vents. This distribution al-
lows adequate air diffusion and main-
tains a good level of comfort both in
summer and winter.
The set distribution is shown by the cor-
responding LEDs on the selected buttons.
To restore automatic air distribution con-
trol after a manual adjustment, press but-
ton AUTO.

Fan speed adjusting buttons (H)
Press button Hto increase or to decrease
the fan speed and therefore the amount
of air admitted into the passenger com-
partment,
although keeping the required
temperature set.
The fan speed is shown by the lit bars on
the display:
max fan speed = all bars lit;
min fan speed = one bar lit.
The fan can be cut off only if the climate
control compressor has been
switched
off pressing button F-fig. 34.
IMPORTANT To restore automatic fan
speed control after a manual adjustment,
press button AUTO.
IMPORTANT At high speeds, the dynamic
effect may increase the flow of air into the
passenger compartment which in this case
will not directly correspond to the fan
speed bar display.AUTO (A) (automatic operation)
Press AUTO to make the system auto-
matically adjust the quantity and distribu-
tion of the air introduced into the pas-
senger compartment. All previous manu-
al settings will be cancelled.
The message FULL AUTOwill appear
on the front display in this condition.
By manually intervening on at least of the
functions automatically managed by the
system (air recirculatio n, fan speed or
compressor on/off), the word FULL will
disappear from the display indicating that
the system is no longer automatically con-
trolling all the functions (the temperature
will still be controlled automatically by the
system).
IMPORTANT Sho uld the system (aft er
manual setting s) be no lon ger able to
guarantee the required temperature set
in the passen ger compartment, the set
temperature value will start flashing to in-
dicate this condition, after one minute the
AUTOmessage will turn off.
To restore system automatic control at
any time, after one or more manual ad-
justments, press button AUTO.Air recirculation on/off button (G)
Air recirculation works according to the
following operating logics:
override on (inside air recirculation
always on),
indicated by the the LED
on button Gand symbol on
the display;
override off (air recirculation always
off and introduction of external air),
indicated by the fact that the LED on
the button is off is on the display.
These operating conditions are obtained
by pressing Gin sequence.
IMPORTANT The inside air recircula-
tion system makes it possible to reach
the required heating or cooling condi-
tions 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.
Recirculation is forced off
(i.e. air is
introduced from the outside) when the
the outside temperature is cold to pre-
vent misting up.
It is advisable not to use the air recircu-
lation function when the outside tem-
perature is low to prevent the windows
from rapidly misting up.

prevent misting up.
Although the system
is capable of maintaining the required tem-
perature, the word FULLwill disappear
from the display.
If on the other hand the
system cannot maintain the required tem-
perature, the digits will blink and the word
AUTOwill disappear.IMPORTANT With the compressor off,
it is not possible to introduce air cooler
than ambient temperature into the pas-
senger compartm ent. Furthermore,
in
certain condition s, the windows could
mist up rapidly because the air is not de-
humidified. The switching off of the climate
control compressor remains in storage
even when the engine has been stopped.
To restore automatic compressor control,
press again (in this case, the system will
only work as a heater) or press AUTO.
With climate control compressor off,
