The turning on of the warning light Bin-
dicates that the coolant fluid temperature
is too high; in this case, stop the engine
and contact a Fiat Dealership.
This shows the temperature of the engine
coolant fluid and begins working when the
fluid temperature exceeds approx. 50°C.
Under normal conditions, the needle
should move to different positions of the
scale according to the working conditions
and engine cooling conditions. FUEL LEVEL GAUGE fig. 19
This shows the amount of fuel left in the
fuel tank.
The reserve warning light Aturns on to
indicate that approx. 7 to 9 litres of fuel
are left in the tank.
E- tank empty.
F- tank full (see the indications given in
paragraph “At the filling station").
Do not travel with the fuel tank almost
empty: the gaps in fuel delivery could dam-
age the catalyst.

Window demisting
In the event of considerable outside mois-
ture and/or rain and/or considerable dif-
ferences in temperature inside and out-
side the passenger compartment, perform
the following preventive demisting proce-
dure:
❒turn air recirculation off by pressing
button G(button led off);
❒turn knob Cto red sector;
❒turn knob Eto 2;
❒turn knob Ato y, or to ™the win-
dows do not demist.
IMPORTANT Climate control system is
very useful to speed up window demist-
ing: therefore, just perform demisting as
previously described and turn the climate
control system on by pressing button B.HEATED REAR WINDOW AND
DOOR MIRROR DEMISTING/
DEFROSTING
Press button Fto start this function.
This function is timed and switches off au-
tomatically after 30 minutes. To cut out
this function press again button
O.
IMPORTANT Do not apply stickers on
the inside of the rear window over the
heating filaments to avoid damage that
might cause it to stop working properly.
FAN SPEED ADJUSTMENT
To ventilate the passenger’s compartment
properly, proceed as follows:
❒open completely central vents and side
outlets;
❒turn knob Cto the blue sector;
❒turn knob Eto the required speed;
❒turn air recirculation off by pressing
button G(button led off);
❒turn knob Ato O.RECIRCULATION
Turn this function on by pressing button
G(button led on).
This function is particularly useful when
the outside air is heavily polluted (in a traf-
fic jam, tunnel, etc.). However, it is bet-
ter not to use it for long periods, espe-
cially if there are several people in the car
to prevent window misting.
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
considerably increase the possibility of the
windows misting inside.

During winter, the climate control system
must be turned on at least once a month
for about 10 minutes. Before summer,
have the system checked at a Fiat Deal-
ership.
AUTOMATIC CLIMATE
CONTROL SYSTEM
(where provided)
GENERAL
The car is fitted with a two-zone climate
control system which makes it possible to
separately adjust the air temperature on
the driver’s side and on the passenger’s
side. Temperature control is based on the
“equivalent temperature” logic, i.e.: the
system continuously works to keep con-
stant the comfort inside the passenger
compartment and to compensate any vari-
ation of the outside climate conditions, in-
cluding sunshine detected by a proper sen-
sor provided for the purpose.
The system is also fitted with AQS (Air
Quality System) sensor that turns on air
recirculation automatically when it detects
the presence of outside polluted air (for
example when driving in the city, queues
and tunnels).

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.

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.
WARNING

❒clean and protect the painted parts us-
ing protective wax;
❒clean and protect the shiny metal parts
using special compounds readily avail-
able;
❒sprinkle talcum powder on the rubber
windscreen and rear window wiper
blades and lift them off the glass;
❒slightly open the windows;
❒cover the car with a cloth or perfo-
rated plastic sheet. Do not use sheets
of non-perforated plastic as they do
not allow moisture on the car body to
evaporate;
❒inflate tyres to +0,5 bar above the
normal specified pressure and check it
at intervals;
❒if you don’t disconnect the battery
from the electric system, check its
charge every month and recharge it if
the optical indicator shows a dark
colour without the central green area;
❒do not drain the engine cooling sys-
tem.
IMPORTANT Where relevant, switch off
the car alarm with the remote control.
CAR INACTIVITY
If the car is to be left inactive for longer
than a month, the following precautions
should be noted:
❒park the car in covered, dry and if pos-
sible well-ventilated premises;
❒engage a gear (position P with auto-
matic transmission);
❒check that the handbrake is not en-
gaged;
❒disconnect battery terminals (first dis-
connect the negative terminal) and
check the battery charge. This check
is to be repeated every three months
when the car is left inactive. Recharge
if the optical indicator shows a dark
colour without the central green area;

ENGINE COOLANT FLUID fig. 11
The coolant level shall be checked with
cold engine and shall not be lower than
the minimum mark on the reservoir.
If the level is low, pour slowly a mixture
of 50% distilled water and 50% PARAFLU
UP by FL Selenia through the filler neck A.
A 50% mixture of distilled water and
PARAFLU UP gives freeze protection to
–22°C. Used engine oil and filter con-
tain harmful substances for
the environment. Contact Fi-
at Dealership to have the oil
and filter changed.
Engine oil consumption
Max engine oil consumption is usually 400
grams every 1000 km.
When the car is new, the engine needs
to run in, therefore the engine oil con-
sumption can only be considered stabilised
after the first 5000 - 6000 km.
IMPORTANT The oil consumption de-
pends on driving style and the conditions
under which the car is used.
IMPORTANT Do not add oil with speci-
fications other than that already in the en-
gine.fig. 11F0L0194m
The cooling system uses
PARAFLU UP antifreeze. Do
not add fluid having different
specifications from that al-
ready existing. PARAFLU UP cannot be
mixed with other types of fluids. Should
other fluids be added, do not start the
engine and contact Fiat Dealership as
soon as possible.
Do not remove the reservoir
cap when the engine is hot:
you risk scalding yourself.
WARNING
The cooling system is pres-
surised. If necessary, replace
the cap only with another genuine
one, otherwise system efficiency could
be compromised.
