paragraph “At the filling station").
The warning light Aturns on to indicate
that approximately 10/12 litres (according
to versions) of fuel are left in the tank.
Do not travel with the fuel tank almost
empty: the gaps in fuel delivery could dam-
age the catalyst.
IMPORTANT The needle sets to Ewith
warning light Aflashing to indicate that the
system is failing. In this event contact Fiat
Dealership to have the system checked.
IMPORTANT Do not turn the supple-
mentary heater (Webasto) on, under fu-
el reserve conditions.ENGINE COOLANT
TEMPERATURE GAUGE fig. 15
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 hover around the middle of the
scale according to the working conditions.

HHigh engine coolant temperature.The turning on of the warning light B(on
certain versions with a message on the

this case, stop the engine and contact a Fi-
at Dealership.

Air temperature
adjusting knob (I)
temperatura
Turning the knob
clockwise or counter-clockwise,
respectively raises or lowers the
temperature of the air required in the
passenger compartment.
Set temperature is shown on the
display.
Turning the knob fully clockwise or
counter-clockwise until it reaches 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).
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. Under
these conditions, the system is no longer
controlled by the automatic temperature
adjustment system and sets air mixing to
maximum heating by modulating speed
and air distribution.
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.
❒LO function (highest cooling power:
this is turned on by rotating the temper-
ature knob counter-clockwise and passing
the min. temperature value (16 °C).
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. Under
these conditions, the system is no longer
controlled by the automatic temperature
adjustment system and sets air mixing to
maximum cooling by modulating speed
and air distribution. 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.

With the compressor off, if the outside
temperature is higher than set, the system
is not able to meet the request. This is in-
dicated by the temperature setting flash-
ing, after which the AUTO message is
turned off.
With the compressor disabled, it is pos-
sible to zero the fan speed manually (no

With the compressor enabled and the en-
gine started, the fan speed may only drop
to minimum (one bar displayed).Fast window

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

❒activates proper fan speed according
to engine coolant temperature to lim-

❒turns heated rear window on
IMPORTANT Fast demisting/defrosting
function stays on for about 3 minutes,
since engine coolant temperature reach-
es a temperature suitable for fast window
demisting.
When the max. demisting/defrosting func-
tion is on, the button led and the heated
rear window button led will turn on; FULL

In cold weather, the supplementary heater
warms and circulates constant tempera-
ture fluid in the engine cooling system for
the time required to ensure optimal en-
gine ignition and passenger compartment
temperature conditions.
The heater can be started automatically
(programmed by means of the digital
timer) or manually by pressing the “heat
now” button on the timer.
When the heater is turned on (automat-
ically or manually), the electronic control
unit operates the fluid circulation pump
and safely ignites the burner according to
preset and controlled modes.

❒digital timer A-fig. 54to start the
heater manually or to program staring
time.The electronic control unit also controls
the circulation pump delivery in order to
reduce initial heating time. When the sys-
tem is operating, the control unit operates
the heater unit fan to the second speed.
Thermal power is adjusted automatically
by the control unit according to the en-
gine coolant temperature.

IMPORTANT The heater is equipped with
a thermal switch which cuts off the heater
in the event of overheating caused by low
or leaking coolant. In this case, press the
program selection button to start the
heater again after repairing the cooling sys-
tem fault and/or topping up the fluid.
The heater can turn itself off after engine
ignition or if the flame goes out. In this
case, turn the heater off manually and at-
tempt to turn it back on again. If you can-
not turn the heater on, contact a Fiat
Dealership.Turning the heater on
If an automatic climate control system is
fitted, the control unit sets air tempera-
ture and distribution when the parking
heater is turned on.
When a manual heater/climate control
system is fitted, to achieve peak heater
performance, check that the passenger
compartment heater/ventilation unit air
temperature knob is in “warm air” posi-
tion.
For preferential passenger compartment
preheating, turn the air distribution knob
to position
©.
For preferential windscreen demisting, set
the air distribution knob to position

tribution knob to position

❒Always remember to turn the heater
off when refuelling or standing in ser-
vice stations to avoid fires and explo-
sions.
❒Do not park the vehicle over inflam-
mable material such as paper, dry grass
or leaves: fire risk!
❒The temperature near the heater must
never exceed 120°C (e.g. during paint-
ing operations in a workshop oven).
Higher temperatures could damage
the electronic control unit compo-
nents.
❒When the engine is off, the heater takes
power from the battery: it is conse-
quently important to run the engine for
a certain period of time in order to re-
store the battery charge.
❒Follow the prescriptions in section
“Vehicle maintenance” at paragraph
“Engine coolant level” to check the
coolant level. The coolant in the cir-
cuit must contain at least 10% an-
tifreeze fluid.
❒Maintenance and repairs must always
be carried out by a Fiat Dealership and
only genuine spare parts must be used.
MAINTENANCE
Have the heater checked at a Fiat Deal-
ership periodically (always before winter).
This will ensure safe and cheap running
and long appliance life.
The heater burns fuel in the
same way as the engine,
though, of course, to a lesser degree
and therefore to avoid intoxication
and suffocation, never use the sup-
plementary heater in closed areas,
garages or workshops not equipped
with specific exhaust evacuation de-
vices even for short periods of time.
WARNING
IMPORTANT The parking heater goes off
when the battery voltage is low to enable
the vehicle to be started up.
IMPORTANT Before turning on the de-
vice, ensure that the fuel level is higher
than the reserve. Otherwise the device
could lock and require the assistance of
the Fiat Dealership.
