2003 FIAT BARCHETTA catalytic converter

ENGINE START-UP
Make sure the handbrake is pulled up; put the gear lever into neutral; press the clutch pedal down to the floor
without touching the accelerator, then turn the ignition key to AVVand release it as soon as the engine
starts.

MUST BE READ!
REFUELLING
Only refuel with unleaded petrol with octane rating (RON) no less than 95.


K
PARKING OVER INFLAMMABLE MATERIAL
When functioning normally, the catalytic converter reaches high temperatures. For this reason do not park
the car over inflammable material, grass, dry leaves, pine needles, etc.: fire hazard.

tion is fitted in your car.

COOLANT TEMPERATURE
GAUGE A-fig. 29
Under normal conditions, the needle
of the temperature gauge should hov-
er around the middle of the scale. If
it approaches the red section it means
the engine is being overtaxed and you
should reduce your demands on it.
Travelling too slowly when the out-
side temperature is very hot can also
cause the needle to approach the red
sector.
In this case it is better to stop and
turn off the engine. After a few mo-
ments you can start the engine again
and accelerate slightly.FUEL GAUGE B-fig. 29
The needle shows the number of
litres of fuel probably in the tank.
When the Kreserve warning light
comes on, it means that about 5 litres
of fuel are left in the tank.
Never travel with the fuel tank al-
most empty: any gaps in fuel supply
could damage the catalytic converter.DIGITAL CLOCK fig. 30
This a twenty-four hour clock. When
the headlights are turned on the fig-
ures will automatically grow dim to
make them easier to read.
To set the hours: press button A.
To set the minutes: press button B.
Press the button once to forward
one unit at a time. Keep the button
pressed to fast forward automatical-
ly. When you are close to the time
you wish to set, release the button and
press the button as many times as re-
quired.
If the conditions persists
even after the measures
you have taken, turn off
the engine and have the car seen
to at a Fiat Dealership.

HAZARD LIGHTS

are on.AIRBAG OR

FAILURE (red)
When the system is not working
properly or has been triggered.
SEAT BELTS NOT
FASTENED (red)
When the driver’s seat
belt is not fastened properly. CATALYTIC
CONVERTER HOT
(red) (where fitted)
When the temperature of the cat-
alytic converter is extremely high: the
warning light will go out as soon as the
temperature drops to normal.

f¬
r
When you turn the ignition
key to the MAR position
this light comes on. It should, how-
ever, go out after about four sec-
onds. If the light stays on or comes
on while the car is moving, stop at
once and have the car seen to at a
Fiat Dealership.
WARNING
The lighting of warning
light >when the engine is
running normally indicates a fault
in the ABS system only. In this case,
the braking system will still be ef-
fective without the anti-lock device.
In these conditions EBD system op-
eration can be reduced. Also in this
case we recommend immediately
taking the car to a Fiat Dealership
avoiding sudden braking to have
the system checked.
WARNING

65
A catalytic converter
that does not work prop-
erly leads to the emission
of harmful gases and the conse-
quent pollution of the atmos-
phere.
Never put even the tini-
est amount of leaded
petrol into the fuel tank,
even in an emergency. You would
damage the catalytic converter
beyond repair.FUEL FILLER CAP
The cap is provided with a strap A-
fig. 82fastening it to the flap so that
is cannot be lost..
To open:hold the cap still and turn
the key anti-clockwise. Turn the cap
by half a turn anti-clockwise and re-
move it.
The air-tight cap can cause a slight in-
crease in pressure inside the fuel tank.
A suction noise when removing the
cap is, therefore, perfectly normal.The cap can be positioned directly on
the flap while refuelling as shown in
fig. 82.
To close: insert the cap (with key)
and turn it clockwise until it clicks
once or twice. Hold the cap still, turn
the key clockwise and remove it.
IMPORTANT If the fuel filler cap
needs changing, use only genuine
spares, otherwise you risk damaging
the fuel vapour recovery system.
fig. 82
P5S10051m
Do not put naked flames or
lighted cigarettes near the
fuel filler hole as there is a danger of
fire. Do not bend too close to the
hole either so as not to breathe in
harmful vapours.

PROTECTING THE
ENVIRONMENT
Protecting the environment has been
the guiding principle in the design of
the Fiat barchetta right from the start.
The result is the use of materials and
creation of devices that can reduce or
considerable curtail harmful influences
on the environment.
The Fiat barchetta is ready to travel
well ahead of the most stringent in-
ternational pollution control stan-
dards.
USE OF MATERIALS
THAT DO NOT HARM
THE ENVIRONMENT
None of the car’s components con-
tain asbestos. Padding and the climate
control system do not contain CFI’s
(Chlorofluorocarbides) the gases con-
sidered responsible for the destruc-
tion of the ozone layer. Other sub-
stances which may pollute the air and
water tables, such as cadmium used in
bolt anti-rust coverings and the chro-
mate used in some colourings, have
been replaced entirely with environ-
mentally-friendly substances. DEVICES FOR REDUCING
PETROL ENGINE EMISSIONS
Three-way catalytic converter
(catalytic exhaust pipe)
Carbon monoxide, nitrogen oxides
and unburned hydrocarbons are the
main harmful components in exhaust
gases.
The catalytic exhaust pipe and the
devices connected to it are a “minia-
ture laboratory” where a very high
percentage of these components is
converted into harmless substances.
The conversion is aided by minute
particles of precious metals on the ce-
ramic core enclosed in the stainless-
steel container.Lambda Sensor
All petrol versions are fitted with this
device. It ensures that air and fuel are
constantly mixed in the correct pro-
portions. This is a fundamental condi-
tions for the proper functioning of the
engine and the catalytic converter.
Anti-evaporation canister
As it is impossible to stop the build-
up of petrol fumes even when the en-
gine is not running, the system traps
them in a special active carbon canis-
ter. They are sucked in from here and
burnt while the engine is running.

79
If the engine begins to “lose its
smoothness” when travelling, contin-
ue your journey but reduce the
demands you are making on the
engine and have the car seen to at a
Fiat Dealership.
When the instrument panel fuel
reserve warning light Kcomes on, fill
up as soon as possible. A low level of
fuel can cause an uneven supply of
fuel to the engine with the inevitable
increase in the temperature of the
exhaust gas and serious damage to
the catalytic converter.
Never run the engine with one or
more spark plugs disconnected, even
for testing purposes.
Do not warm up the engine by let-
ting it idle for a while before moving
off unless the outside temperature is
very low and, even in this case, only
do so for less than thirty seconds.TOWING
A TRAILER
IMPORTANT
The car must be fitted with a
homologated tow hitch and suitable
electrical system for towing a cara-
van or trailer. Have the tow hitch fit-
ted by an expert who will issue spe-
cific documentation for use on
roads.
Fit special and/or additional
rearview mirrors in accordance with
the highway code.
Remember that towing a trailer
makes it harder for the car to climb
the maximum gradients specified,
increases braking and overtaking dis-
tance, proportionally to the overall
weight of the trailer.
The weight the trailer exerts on
the car’s tow hitch coupling reduces
the car’s loading capacity by the
same amount. Do not install other heat shields
and do not remove those already fit-
ted to the catalytic converter and
exhaust pipe.
Do not allow anything to be
sprayed onto the catalytic converter,
lambda sensor and exhaust pipe.
When functioning normal-
ly the catalytic converter
develops high temperatures. For
this reason do not park the car
over inflammable material (grass,
dry leaves, pine needles, etc.): fire
hazard.
WARNING
Failure to heed these pre-
cautions could cause a
fire.
