MUST BE READ!
REFUELLING
Petrol engines:only refuel with unleaded petrol with octane rating (RON) no less than 95.
Diesel engines:only refuel with diesel fuel conforming to the European specification EN590.
The use of other products or mixtures may irreparably damage the engine with invalidation of the warranty
due to the damage caused.
ENGINE START-UP
Petrol engines with manual gearbox:make sure the parking brake is pulled (instrument panel warning light x
on); put the gear lever to neutral; press the clutch pedal down to the floor without touching the accelerator, then turn
the ignition key or the Keyless System knob to AVVand release it as soon as the engine starts.
Engines with automatic electronic transmission (COMFORTRONIC): make sure the parking brake is pulled (in-
strument panel warning light xon) and the gear lever is to P; hold the clutch pedal pressed down to the floor
without touching the accelerator, then turn the ignition key or the Keyless System knob to AVVand release it as soon
as the engine starts.
Diesel engines:make sure the parking brake is pulled; put the gear lever to neutral; press the clutch pedal down
to the floor without touching the accelerator, then turn the ignition key or the Keyless System knob to MAR, and
wait for the instrument panel warning light mto go out, then turn immediately the ignition key or the Keyless
System knob to AVVand release it as soon as the engine starts.
PARKING OVER FLAMMABLE 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.

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.

DEVICES FOR REDUCING DIESEL ENGINE EMISSIONS
Oxidising catalytic converter
This device converts the polluting substances in the exhaust gas (carbon monoxide, unburnt hydro-
carbons and particulates) into harmless substances, thus reducing the smokiness and smell associat-
ed with diesel engine exhaust fumes.
The catalytic converter consists of a stainless steel case containing a honeycomb ceramic core in
which there is the precious metal that carries out the catalysing action.
Exhaust Gas Recirculation (E.G.R.) system
This system recirculates or reuses part of the exhaust gas in a proportion which varies according to
engine operating conditions.
When necessary, it is used for the control of nitrogen oxide emissions.

It is absolutely forbidden
to carry out whatever af-
ter-market operation in-
volving steering system or steering
column modifications (e.g.: instal-
lation of anti-theft Device) that
could badly affect performance
and safety, cause the lapse of war-
ranty and also result in non-com-
pliance of the car with homologa-
tion requirements.

STEERING COLUMN LOCK
The steering column lock is
engaged automatically after remov-
ing the ignition key.IGNITION
SWITCH
The key can be turned to three dif-
ferent positions (fig. 6):
STOP: engine off, key can be
removed, steering column locked.
Some electrical devices can be oper-
ated (e.g. CONNECT).
MAR: driving position correspond-
ing to: dashboard on and steering
column lock off. All the electrical
devices can be operated.
AVV: engine ignition. Release the
key as soon as the engine is started.If the ignition switch has
been tampered with (e.g.
someone has tried to steal
your car), get a Lancia
Dealership to make sure it is still
functioning properly before you
start driving again.
Always remove the igni-
tion key when you get out
of the car. This will pre-
vent anyone from accidentally
working the controls. Remember
to apply the handbrake and, if
the car is faced down on a steep
slope engage the first gear. If it is
facing up, engage the reverse
gear.
IMPORTANTFor versions equip-
ped with the recognition system,
refer to paragraph “Recognition sys-
tem (Keyless System)” in this chap-
ter.

Versions with Keyless System
The steering column lock is
engaged when central door locking
is actuated by means of the remote
control. This condition is indicated
on the instrument panel display by
message “STEERING LOCKED
WHEN DOORS CLOSED”.

THE LANCIA CODE
SYSTEM
To further protect your car from
theft, it has been fitted with an
engine immobilising system (Lancia
CODE) which is automatically acti-
vated when the ignition key is
removed. An electronic device, in
fact, is fitted in each ignition key
grip. The device transmits a radio-
frequency signal when the engine is
started through a special aerial built
into the ignition switch. The modu-
lated signal is a password. Only if
the control unit recognises the key
can the engine be started.OPERATION
Each time the ignition key is
turned to STOPthe Lancia CODE
system will deactivate the engine
electronic control unit functions.
When the key is turned to MARto
start the engine, the Lancia CODE
system sends a password code to the
engine control unit to deactivate the
function lock. The encoded and
variable code, randomly selected
from over four billion possible com-
binations, is only sent if, in turn, the
system has recognised the code
transmitted by the electronic device
built into the ignition key via an aer-
ial surrounding the ignition switch.
If the code has not been recognised
correctly, the symbol Ywill appear
on the instrument panel display,
together with the message “VEHI-
CLE PROTECTION SYSTEM
FAULT”. In this case, turn the key to STOP
and then back to MAR. If the engine
remains immobilised, try with the
other keys provided with the car. If
you are still unable to start the
engine, carry out the emergency pro-
cedure described in chapter “In an
emergency”, and contact your
Lancia Dealership.
IMPORTANTEach key has its
own code that must be stored in the
system control unit. For storing new
keys, up to a maximum of eight,
apply solely to Lancia Dealership
taking with you all the keys in your
possession, the CODE card, a per-
sonal identity document and the
documents that certify car posses-
sion.

27
The codes of any keys
that are not available
when the new storage pro-
cedure is carried out will be
deleted from the memory to pre-
vent any lost or stolen keys being
used to start the engine.IMPORTANTIf symbol Ylights
up when the car is running:
1) If the symbol lights up together
with the message “VEHICLE PRO-
TECTION SYSTEM FAULT”, this
means that the system is running a
self-test (e.g. due to a voltage drop).
The first time you stop, you can test
the system as follows: switch the en-
gine off by turning the ignition key to
STOPthen turn the key back to
MAR: the symbol will light up and go
out in about 1 second. If the symbol
remains on, repeat the above proce-
dure, leaving the key at STOPfor
longer than 30 seconds. If the prob-
lem persists, contact your Lancia
Dealership.
2) If the symbol stays on, this
means that the code has not been
recognised. In this case, turn the key
to STOP and then back to MAR. If
the engine remains immobilised, try
with the other keys provided with
the car. If you are still unable to
start the engine, carry out the emer-
gency procedure (see chapter “In an
emergency”), and contact your
Lancia Dealership. THE KEY
The car is delivered with two
copies of the key A(fig. 7) with
metal insert and power-assisted
opening with built-in remote control
for remote door opening/closing,
boot/tailgate opening and switching
the electronic alarm on/off.

REQUEST FOR ADDITIONAL
KEYS WITH REMOTE
CONTROL
The receiver will acknowledge up
to eight keys with remote control. If
you ever need a new key with remote
control, go directly to a Lancia
Dealership, taking with you the
CODE card, personal identification
and the car ownership papers.ELECTRONIC
ALARM
The system consists of:
– radio-frequency transmitter
(built into the ignition key);
– radio-frequency receiver;
– electronic control unit with built-
in siren (the siren can be deactivat-
ed);
– volumetric sensors (which can be
deactivated);
– anti-lifting sensor (which can be
deactivated).
The electronic alarm is controlled
by the receiver and is switched
on/off by means of the remote con-
trol built into the key, which sends
the secret and variable code. The electronic alarm monitors:
– the illicit opening of doors, bon-
net and boot (perimetral protec-
tion);
– ignition switch operation;
– cutting of battery cables;
– moving bodies inside the passen-
ger compartment (volumetric pro-
tection)
– any abnormal raising/sloping of
the car.
IMPORTANTThe engine immo-
bilising system is governed by the
Lancia CODE system and is auto-
matically activated when the igni-
tion key is removed.
