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 vto 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 intervene 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.
❒Tair recirculation, to keep the
function always either on or off;
❒Zto 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 recirculation settings 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.

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. 40.
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 recirculation, 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 Should the system (after
manual settings) be no longer able to
guarantee the required temperature set
in the passenger 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 Ton
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 êis 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.

Press √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 automatically system control
and use of the compressor. The icon
will light up on the display in this case.
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 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 introduced air cooler
than ambient temperature into the pas-
senger compartment. Furthermore, in
certain conditions, 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, the
fan speed can be set to zero manually (no
bar shown).
With the compressor enabled and the en-
gine started, the fan speed may be reduced
to the minimum setting (only one bar
shown).Fast window demisting/defrosting
button (D)
Press this button: the climate control sys-
tem will automatically switch on all the
functions required for fast windscreen and
front side window demisting/defrosting,
that is:
❒switches on climate control compres-
sor when climatic conditions are suit-
able;
❒air recirculation off;
❒maximum air temperature HI on both
areas;
❒operates proper fan speed according
to engine coolant temperature to lim-

CORRECT USE
OF THE CAR
Roof rack/ski rack
Remove the roof rack or the ski rack from
the roof after use. These accessories de-
crease aerodynamic penetration of the car
and have a negative effect on consumption.
It is better to use a trailer to transport
particularly bulky objects.
Electric devices
Use electric devices only for the amount
of time needed. Rear heated window, ad-
ditional headlights, windscreen wipers and
heater fan need a considerable amount of
energy, therefore increasing the require-
ment of current increases fuel consump-
tion (up to +25% in the urban cycle).
Climate control
The climate control system requires high-
er fuel consumption (up to +20% in av-
erage): use the air vents when the exter-
nal temperature allows to.
Spoilers
The use of non-certified aerodynamic
items may adversely affect air drag and
consumption levels.DRIVING STYLE
Starting
Do not warm the engine up with the car
standing: the engine warms up very slow-
ly in these conditions, increasing con-
sumption and emissions. It is advisable to
start off immediately and slowly keeping
the engine speed down: the engine will
warm up much faster this way.
Unnecessary actions
Avoid revving up when starting at traffic
lights or before stopping the engine. The
latter action, like doubling the clutch, is un-
necessary and causes increase of con-
sumption and pollution.
Gear selection
Use a higher gear as soon as traffic and
road conditions allow. Using a low gear
for faster acceleration will increase con-
sumption.
In the same way improper use of a high
gear increases consumption, emissions an
engine wear.CONTAINING
RUNNING COSTS
Here are some suggestions which may
help you to keep the running costs of your
car down and lower the amount of toxic
emissions released into the atmosphere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out
in accordance with the “Service schedule”.
Tyres
Check tyre pressure regularly at least
once every four weeks: excessively low
pressure will increase consumption be-
cause rolling resistance will be higher.
Unnecessary loads
Do not travel with too much luggage
stowed in the boot. The weight of the car
(especially when driving in town) and its
trim greatly affects consumption and sta-
bility.
