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

START-UP CHECKS
When turning the ignition key to
MARto start the engine, the system
starts monitoring the main car sys-
tems, the engine oil level (JTD ver-
sions only) and indicates the next
Scheduled Servicing.

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.

Even in fault conditions it is possi-
ble to move the lever to R, Nand D.
If the lever is in position D,the con-
trol unit of the automatic gearbox
will select only certain gears, accord-
ing to the type of failure detected.
In case of failure of the
automatic gearbox, take
the car immediately to a
Lancia Dealership to have the
failure eliminated.FAILURE INDICATION
Automatic gearbox faults are indi-
cated by multifunction display
warning light tcoming on with
the following messages:
– AUTOMATIC TRANSMISSION
OIL TEMP. HIGH
– AUTOMATIC TRANSMISSION
FAULT.
Automatic transmission oil tem-
perature high
This message is displayed when the
gearbox oil has reached the maxi-
mum preset temperature. In this
case the electronic control unit has
an emergency programme.
Anyway, it is suggested to stop the
car, to set the lever to Por Nand to
keep the engine running idle until
the message displayed disappears.
Then start driving again without
taxing the engine.If the message is displayed again,
re-stop the car and let the engine
run idle until the message disap-
pears.
If the interval between the first and
second message appearance is lower
than 15 minutes, stop the car, stop
the engine and wait until the engine-
gearbox unit is completely cold.
Automatic transmission fault
If this message is displayed during
driving, it means that there is a fail-
ure in the automatic gearbox. In this
case the electronic control unit has
an emergency programme.
In such conditions, stop the car and
stop the engine for at least 1 minute.
When the engine is restarted, the
self-diagnosis system could exclude
that failure, that however will be
stored by the electronic control unit.
