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.

DRIVING YOUR CAR
To help you handle your Fiat barchetta in the best
and safest possible way, and above all use it to its
fullest potential, we have given you some hints in this
chapter on “what to do, what not to do and what to
avoid” when at the wheel of your Fiat barchetta.
Most of the time, these suggestions apply to other
cars as well. Sometimes, however, the tip may apply
to an exclusive Fiat barchetta feature. You are there-
fore strongly recommended to pay the closest atten-
tion to this section for helpful hints on optimum dri-
ving practices and usage of the car that will help you
get the most out of your Fiat barchetta. STARTING THE ENGINE ............................................... 68

If warning light ¢remains lit
together with the warning light
U
when the ignition key is at MAR,
turn the key toSTOPand then to
MAR; if the warning light still
remains lit, try with the other keys
provided with the car.
If you are still unable to start the
engine, follow the emergency startup
procedure (see “Emergency startup”
in the section “In an emergency”)
and go to the nearestFiat
Dealership immediately.
IMPORTANTDo not leave the
ignition key at MARwhen the
engine is off.
STARTING
THE ENGINE
The engine may seem noisier than
usual during the first seconds after
startup, especially after a long period
of inactivity. This phenomenon is
characteristic of hydraulic tappets,
and does not affect the functioning
and reliability of the engine: this par-
ticular timing system has been select-
ed for the Fiat barchetta engine to
reduce the number of maintenance
interventions necessary.IMPORTANT It is important that
the accelerator is never pressed until
the engine is started.
1) Make sure the handbrake is on.
2) Put the gear lever in neutral.
3) Press the clutch pedal right
down, without touching the acceler-
ator pedal.
4) Turn the ignition key to AVV
and let it go the moment the engine
starts.
If the engine does not start at the
first attempt, return the ignition key
to STOPbefore trying to start the
engine again.
It is dangerous to let the
engine run in a garage or
other closed area. The engine con-
sumes oxygen and gives off carbon
dioxide, carbon monoxide and oth-
er poisonous fumes.
WARNING
Never touch the high ten-
sion cables (spark plug
cables) when the engine is run-
ning.
WARNING

HOW TO WARM UP
THE ENGINE AFTER
IT HAS JUST STARTED
– Begin to move forward slowly, let-
ting the engine turn over at medium
revs. Do not floor the accelerator.
– Do not push the engine to its lim-
it for the first few kilometres. You are
recommended to wait until the water
temperature has reached 50° to 60°C.
EMERGENCY START-UP
If the Fiat CODE system fails to
recognise the code transmitted by
the ignition key (warning lamp ¢on
instrument panel lit with a fixed
light), you can start the engine by fol-
lowing the emergency procedure
using the code written on the CODE
card.
See the section “In an emergency”.Do not bump start by
pushing, towing or coast-
ing downhill. This way of
starting could cause a rush of fu-
el into the catalytic exhaust pipe
and damage it beyond repair.
A quick burst on the ac-
celerator before turning
off the engine serves ab-
solutely no practical purpose and
wastes fuel.
IMPORTANT After a taxing drive it
is better to allow the engine to “catch
its breath” before turning it off by let-
ting it idle to allow the temperature in
the engine compartment to fall.STOPPING THE ENGINE
Turn the ignition key to STOP
while the engine is idling.
Remember that as long as
the engine is not running,
the power brakes and power steer-
ing do not work. You therefore have
to use considerably more effort on
both the brake pedal and the steer-
ing wheel.
WARNING

70
PARKING
Turn off the engine, pull up the hand-
brake, put the car in gear (1st if the car
is pointing uphill, reverse if downhill)
and turn the wheels. If the car is on a
steep incline, you should put a stone
or wedge under the wheels to block
them.
Do not leave the ignition key at
MAR because it drains the battery.
Always remove the key when you
leave the car.IMPORTANTIf this is not the
case, have the handbrake adjusted at
a Fiat Dealership.
When the hand brake is on and the
ignition key is at MAR, panel indica-
tor light xcomes on.
To release the handbrake:
1) Slightly lift the handbrake and
press release button A.
2) Keep the button pressed in and
lower the lever. Instrument panel in-
dicator light xwill go out.
3) To prevent the vehicle acciden-
tally moving, carry out this manoeuvre
with the brake pedal pressed. HANDBRAKE fig. 1
The handbrake lever is situated be-
tween the two front seats.
To operate the handbrake pull the
lever upwards until the car is pre-
vented from moving: pulling the lever
through four or five “clicks” is gener-
ally enough on level ground while nine
or ten might be necessary on a steep
incline and with a load in the car.

unsupervised in the car.
WARNING

71
GEAR USE
To engage the gears, press down
the clutch and put the gear lever into
one of the positions shown in the
diagram infig. 2(the diagram is also
on the gear lever knob).
IMPORTANT The car can be put
in reverse only when it has com-
pletely stopped moving. With engine
running, before engaging the reverse,
wait at least 2 seconds with clutch
pedal completely pressed down to
prevent damage and grating of gears.
Do not drive with your
hand resting on the gear
stick as the force exerted,
even if only slight, could lead to
premature wearing of the gear-
box internal components.

SAFE DRIVING
In designing the Fiat barchetta, Fiat
has made every effort to come up with
a car able to provide driver and pas-
senger with top-class levels of safety.
Nevertheless it is always the behaviour
of the person at the wheel that de-
termines road safety.
Below you will find some simple tips
to help you travel in safety under dif-
ferent conditions. You will no doubt
be familiar with many of them already
but it will be useful to read them all
carefully.
You must push the clutch
pedal fully down to change
gear properly. It is therefore essen-
tial that there is nothing under the
pedals: make sure mats are lying
flat and do not get in the way.
WARNING

73
– Do not drive too many hours at a
time but stop at intervals to stretch
your legs and recoup your energies.
– Make sure the air in the car is be-
ing changed continuously.
– Never coast down steep slopes
with the engine off: you lose the aid of
engine brake, power brakes and pow-
er steering so that braking and steer-
ing require greater effort.
DRIVING AT NIGHT
If you are driving at night these are
the main rules to follow.
– Drive especially carefully: it is hard-
er to drive at night.
– Slow down especially if the road is
not lit.
– At the first signs of sleepiness, stop:
continuing would be a risk for yourself
and everybody else. Only start driving
again when you have had enough rest.
Driving while drunk or un-
der the influence of drugs
or certain medicines is dangerous
for both you and other road users.
WARNING
Always fasten your seat
belt and ensure your pas-
senger does the same. Travelling
with the seat belts unfastened in-
creases the risk of injury or death
if you are in a collision.
WARNING
Water, ice or salt on road
surfaces can deposit on
brake disks, reducing braking effi-
ciency on the first braking.
WARNING
Pay attention to assembly
of extra spoilers, wheels in
alloy or non standard wheel caps.
These could reduce ventilation of
the brakes and reduce their effi-
ciency under conditions of violent
or repeated braking or long down-
hill travel.
WARNING
Do not travel with objects
on the floor in front of dri-
ver’s seat: when braking they could
block the pedals making accelera-
tion or braking impossible.
WARNING
Pay attention to the mea-
surements of any carpets:
any hindrance, even slight, to the
braking system could result in a
longer than normal pedal run.
WARNING

75
– Remember that fog also means the
tarmac is wet and therefore manoeu-
vres of all kinds are more difficult and
stopping distances are longer.
– Keep a good distance from the cars
in front of you.
– As far as possible, avoid spurts of
speed or sudden deceleration.
– Do not overtake other vehicles if
you can help it.
– If you are forced to stop your car
(breakdown, limited visibility etc.) try
to stop off the road. Then turn on the
hazard lights and, if possible, the
dipped headlights. Rhythmically sound
the horn if you realise another car is
coming.
DRIVING
IN THE MOUNTAINS
– When driving downhill, use the en-
gine brake by engaging a low gear so
as not to overheat the brakes.
– Under no circumstances should
you drive downhill with the engine off
or with the car in neutral, let alone
with the ignition key out.– Drive at a moderate speed without
cutting corners.
– Remember that overtaking while
going uphill is slower and therefore re-
quires more free road. If you are be-
ing overtaken while driving uphill,
make it easier for the other vehicle
to pass.
DRIVING ON SNOW OR ICE
Here are some tips for driving in
these conditions:
– Keep your speed down.
– Use chains if the roads are covered
in snow (refer to the “Snow chains”
paragraph in this section).
– Mainly use the engine brake and
under all circumstances avoid braking
sharply.
– When braking in a car not fitted
with ABS, avoid the wheels locking by
varying the pressure you exert on the
brake pedal.
– Do not accelerate suddenly and
avoid swerving.– In the winter, even apparently dry
roads may have icy patches. Be care-
ful therefore when driving over
stretches that do not get much expo-
sure to the sun or that are lined by
trees and rocks where ice might not
have melted.
– Keep a good distance from the ve-
hicles in front.
– Do not remain for long periods in
deep snow with the engine running as
the snow could force the exhaust gas-
es into the passenger compartment.
DRIVING WITH ABS
ABS is a braking system that essen-
tially offers two advantages:
1)It prevents wheel lock-up and
consequent skidding in emergency
stops, particularly when the road does
not offer much grip.
2)It makes it possible to brake and
steer at the same time so you can
avoid unexpected obstacles and direct
the car where you want while braking.
The extent to which this can be done
will depend on the physical limits of
the tyre's sideways grip.

77
Electric devices
Use the electrical devices for the
necessary time only. The heated rear
window, supplementary lights, wind-
screen wipers, heating system blow-
er require large amounts of energy
and, increasing the request for pow-
er also increase fuel consumption (up
to +25% when driving in towns).
Air conditioner
The air conditioner is an additional
load which greatly affects the engine
leading to higher consumption (on av-
erage up to +20%). When the tem-
perature outside the vehicle permits
it, use the air vents.
Spoilers
The use of aerodynamic optional
extras which are not certified for
specific use on the vehicle may
reduce the aerodynamic penetration
of the car and increase consumption.STYLE OF DRIVING
Starting
Do not warm the engine when the
vehicle is stationary or at high or low
revs: in this way the engine will warm
up gradually increasing consumption
and emissions. You should drive off
slowly straight away avoiding high revs,
so that the engine will warm up more
quickly.
Unnecessary actions
Avoid revving the engine when
stopped at traffic lights or before
switching off the engine and avoid dou-
bling the clutch as these actions have
no purpose on modern cars and only
increase consumption and pollution.
Gear selection
As soon as the traffic and road con-
ditions allow it, shift to a higher gear.
Using a lower gear to liven up accel-
eration greatly increases consumption.
In the same way, improper use of the
higher gears will increase consump-
tion, emissions and wear and tear on
the engine.Top speeds
Fuel consumption increases consid-
erably as speed increases. For exam-
ple, when accelerating from 90 to 120
kph, fuel consumption increases by
about +30%. Your speed should be
kept as even as possible and superflu-
ous braking and acceleration avoided
as this increases both consumption
and emissions. A “soft” way of driving
should be adopted by attempting to
anticipate manoeuvres to avoid immi-
nent danger and to maintain a safe dis-
tance from the vehicle in front in or-
der to avoid braking sharply.
Acceleration
Accelerating violently increasing the
revs will greatly affect consumption
and emissions: acceleration should be
gradual and should not exceed the
maximum torque.

78
CONDITIONS OF USE
Cold starting
Frequent cold starting will not enable
the engine to reach optimal running
temperature. It follows therefore that
consumption will be higher (from
+15% to +30% in towns) as will the
production of toxic emissions.
Traffic and road conditions
Heavy traffic and higher consumption
are synonymous; for example, when
driving slowly with frequent use of the
lower gears or in large towns where
there are numerous traffic lights.
Winding roads, mountain roads and
bumpy roads also have a negative ef-
fect on consumption.
Enforced halts
During prolonged hold-ups (traffic
lights, level crossings) the engine
should be switched off.CHEAP RUNNING THAT RESPECTS
THE ENVIRONMENT
LOOKING AFTER EMISSION
CONTROL DEVICES
The correct use of pollution control
devices not only ensures respect for
the environment but also has an effect
on the car’s performance.
Keeping these devices in good con-
dition is therefore a fundamental rule
for driving that is easy on your pock-
et and on the environment too.
The first step to take is to follow the
Service Schedule to the letter.
Use only unleaded petrol in petrol
engines.
If you have trouble starting, do not
keep turning the ignition key for long
periods. Be especially careful to avoid
bump starting the car by pushing, tow-
ing or rolling down hill: these are all
manoeuvres that can damage the cat-
alytic exhaust. For emergency starts
use only an auxiliary battery. Environmental protection has been
one of the guiding principles in the
production of the Fiat barchetta. It is
no accident that its pollution control
equipment is much more effective than
that required by current legislation.
Nonetheless, the environment can-
not get by without a concerted effort
from everyone.
By following a few simple rules you
can avoid harming the environment
and often cut down fuel consumption
at the same time.
On this subject, a few useful tips have
been given below to supplement those
marked by symbol #, at various points
of the handbook.
You are asked to read both the for-
mer and latter carefully.
