DEVICES FOR REDUCING PETROL ENGINE EMISSIONS
Three-way catalytic converter (catalytic exhaust pipe)
The exhaust system is equipped with a catalyst made up of noble metal alloys; it is housed in a
stainless steel container capable of withstanding the very high operating temperatures.
The catalyst converts the unburnt hydrocarbons, the carbon monoxide and the nitric oxides found
in the exhaust gases (though in small amounts, thanks to the electronic-injection ignition systems)
into non-polluting substances.
When functioning normally, the catalytic converter reaches high temperatures. For this reason do
not park the car over inflammable material (e.g. paper, fuel oil, grass, dead leaves, etc.).
Lambda sensors
The Lambda sensors detect the oxygen content in the exhaust gas. The signal sent by the oxygen
sensor is used by the injection system electronic control unit to constantly mix air and fuel in the cor-
rect proportion.
Fuel evaporation canister
As it is impossible to stop the build up of petrol fumes, also when the engine is not running, the sys-
tem traps them in a special container holding active carbon.
The fumes are sucked in from here and burnt while the engine is running.

SYMBOLS
Special coloured labels have been
attached near or actually on some of
the components of your THESIS.
These labels bear symbols that
remind you of the precautions to be
taken as regards that particular
component.
A list of the symbols to be found on
your THESIS is given below with the
name of the component to which it
relates at the side of it.
These symbols are divided into the
following four categories: danger,
prohibition, warning and obligation.DANGER SYMBOLS
Battery
Explosion.
Fan
May cut in automatically
even when the engine is
turned off.
Expansion tank
Do not remove the cap
when the coolant is hot.
Coil
High voltage.
Belts and pulleys
Moving parts; keep parts
of the body and clothes
away.
Climate control tubing
Do not open. Gas under
high-pressure.
Front headlights
Danger - Electric shocks.

Diesel engines
Use diesel fuel only.
DIESEL
Expansion tank
Only use fluid of the type
specified in section
“Capacities”.
Battery

book.
OBLIGATION SYMBOLS
10
Battery
Keep away from naked
flames.
Battery
Keep away from chil-
dren.
Heat shields - belts -

Do not touch.
PROHIBITION SYMBOLS
Power steering
Do not exceed the maxi-
mum fluid level in the
reservoir. Use only the
fluid specified in section
“Capacities”.
Catalytic converter
Do not park over inflam-
mable materials. See
chapter: “Protecting the
emission control devices”.
WARNING SYMBOLS
Engine
Use only the oil specified
in section “Capacities”.
Unleaded petrol vehicle
Use only unleaded petrol
with a rated octane num-
ber (R.O.N.) of not less
than 95.
Windscreen wiper
Only use fluid of the type
specified in section
“Capacities”.
Brake circuit
Do not exceed the maxi-
mum fluid level in the
reservoir. Use only the
fluid specified in section
“Capacities”.

IMPORTANT If the ¬warning
light does not turn on when turning
the ignition key to MARor if it stays
on when travelling, (together with
message on display) this could indi-
cate a failure in safety retaining sys-
tems; under this condition air bags
or pretensioners could not trigger in
the event of collision or, in a restrict-
ed number of cases, they could trig-
ger accidentally. Stop the car and
contact Lancia Dealershipto have
the system checked immediately.
The air bag system has a validity of
14 years as concerns the pyrotechnic
charge and 10 years as concerns the
coil contact (see the plate on the front
let door). As these dates approach, con-
tact Lancia Dealershipto have them
replaced.
IMPORTANTAfter an accident
which triggered the airbags, go to a
Lancia Dealershipto have the
entire safety system, the electronic
control unit, the seat belts and the
pretensioners replaced and to have
the electrical system checked. Never lean head, arms
and elbows out of the
window.Operation of the front bags is not
disabled by the passenger’s front
airbag and rear side bag deactiva-
tion switch.
IMPORTANTIn the event of side
crash, you can obtain the best pro-
tection by the system keeping a cor-
rect position on the seat, allowing
thus a correct window bag unfold-
ing.IMPORTANTThe front airbags
and/or front and rear side bags can
be triggered if the car is involved in
hard impacts or collisions in the area
of the underbody, such as for exam-
ple violent impacts against steps,
kerbs or projecting objects fixed to
the ground or if the car falls into
large pot-holes or dips in the road
surface.
IMPORTANTWhen the airbag is
fired it emits a small amount of
powder and smoke. This is not
harmful and does not indicate the
beginning of a fire. Furthermore the
surface of the inflated bag and the
passenger compartment may be cov-
ered with powder residues. This
powder may irritate skin and eyes.
In the event of exposure, wash with
mild soap and water.

Never rest head, arms
and elbows on the door,
on the windows and in the
window bag area to prevent pos-
sible injuries during the inflation
phase.

Engine oil level check (JTD versions only)
Indication is correct only if oil level has been checked with the car on a level surface.
If oil level is low, before topping up, check it by the proper dipstick as described in paragraph “Checking fluid levels”
in the “Car maintenance” chapter.
