EOBD SYSTEM
The EOBD system (European On Board Diagnosis) car-
ries out a continuous diagnosis of the components of the
car related to emissions. It also alerts the driver, by turn-
ing on the
Uwarning light in the instrument panel to-
gether with a message in the reconfigurable multifunc-
tion display, when these components are no longer in
peak condition (see “Instrument panel warning lights”
paragraph).
The goal of the system is to:
❍to keep system efficiency under control;
❍to signal a fault which causes emission levels to
increase;
❍to signal the need to replace deteriorated components.
The system also has a diagnosis connector that can be in-
terfaced to suitable instruments, to read the error codes
stored in the control unit together with a series of specific
parameters for engine operation and diagnosis.
This check can also be carried out by traffic control au-
thorities.
Go to a Lancia Dealership as soon as pos-
sible if warning light
Ueither does not light
up when the key is turned to MAR or if,
while travelling, the warning light comes on either
steadily or flashing (along with a message in the
reconfigurable multifunction display). The oper-
ation of the warning light
Umay be checked by the
traffic control authorities using specific devices.
Always comply with the traffic regulations in force
in the country where you are driving.
IMPORTANT After eliminating the problem, to check the
system completely, Lancia Dealerships run a bench test
and, if necessary, road tests which may also call for a long
journey.

“DUALDRIVE” ELECTRIC POWER
STEERING SYSTEM
THIS is an electrically controlled power steering system
called “Dualdrive”. It is only operational with the igni-
tion key turned to MAR and the engine running; it can be
customised by the driver according to the driving condi-
tions.
IMPORTANT When turning the ignition key quickly,
complete power steering functionality may be achieved
after 1-2 seconds.CITY FUNCTION ACTIVATION/DEACTIVATION
Press button A-fig.79 to activate/deactivate the function.
When the function is active, the CITY warning light on
the instrument panel turns on. When the CITY function
is on, the effort required at steering wheel is lighter, mak-
ing parking easier: therefore, this function is particularly
useful for driving in city centres.

FAILURE INDICATIONS
Any failure of the electric power steering is indicated by
instrument panel warning light gcoming on together
with a message in the reconfigurable multifunction dis-
play. In the event of electric power steering system fail-
ure, the car can be driven with mechanical steering.
IMPORTANT In some circumstances, factors independent
of the electric power steering could cause the warning light
gon the instrument panel to come on. In this case, stop
the car immediately, switch off the engine for about
20 seconds and then restart the engine. If the gwarn-
ing light remains on, together with the message on the re-
configurable multifunction display, contact a Lancia
Dealership as soon as possible.
Under no circumstances should aftermarket
operations be carried out involving steering
system or steering column modifications
(e.g. installation of anti-theft device). This could
negatively affect performance and safety, invali-
date the warranty, cause serious safety problems
and also result in non-compliance of the car with
type-approval requirements.
On some versions, with the CITY function
activated, the SPORT function is not avail-
able. To activate the SPORT function, deactivate
the CITY function and vice versa, because they are
reciprocally incompatible.

KNOWING YOUR CAR129
IMPORTANT The steering may become slightly stiff fol-
lowing parking manoeuvres involving a lot of steering.
This is normal and is caused by a system to prevent the
motor from overheating. No servicing is required. The
power steering system will start working normally again
the next time the car is used.T.P.M.S. SYSTEM
(Tyre Pressure Monitoring System)
(for versions/markets, where provided)
The car may be equipped with a tyre pressure monitor-
ing system. This system comprises a radio frequency
transmitter fitted to each wheel (on the wheel rim inside
the tyre), which is able to send information on the tyre
inflation pressure of each wheel to the control unit.
IMPORTANT NOTES ABOUT THE TPMS SYSTEM
The fault indications are not stored and will therefore
not be displayed after the engine has been switched off
and then on again. If the fault conditions persist, the
control unit will send the relative indications to the in-
strument panel only after the vehicle has been in motion
for a short time.
Before starting any servicing operation, stop
the engine and remove the key from the igni-
tion switch to operate the steering lock, par-
ticularly when the wheels do not touch the ground.
If this is not possible (e.g. if the key must be kept in
the MAR position or the engine must be kept run-
ning), remove the electric power steering system
main fuse.

REFUELLING THE CAR
PETROL ENGINES
Use unleaded petrol only, with an octane number (R.O.N.)
not lower than 95.
IMPORTANT An inefficient catalytic converter leads to
harmful exhaust emissions, thus contributing to air pol-
lution.
IMPORTANT Never use leaded petrol, even in small
amounts or in an emergency, as this would damage the
catalytic converter beyond repair.
DIESEL ENGINES
Operation at low temperatures
If the outside temperature is very low, diesel thickens due
to the formation of paraffin clots with consequent defec-
tive operation of the fuel supply system.
In order to avoid these problems, different types of diesel
are distributed according to the season: summer type,
winter type and arctic type (cold/mountain areas). If re-
fuelling with diesel fuel whose specifications are not suit-
able for the current temperature, it is advisable to mix
TUTELA DIESEL ART additive in the proportions
shown on the container with the fuel. Pour the additive
into the tank before the diesel fuel.When using or parking the vehicle for a long time in the
mountains or cold areas, it is advisable to refuel using lo-
cally available diesel fuel.
In this case, it is also advisable to keep the tank over 50%
full.
For diesel engines, use only diesel fuel for
motor vehicles in accordance with EN590
European specifications. The use of other
products or mixtures may damage the engine be-
yond repair and consequently invalidate the war-
ranty, due to the damage caused. If you acciden-
tally introduce other types of fuel into the tank, do
not start the engine and empty the tank. If the en-
gine has run, even for a very short time, you will
need to have the entire fuel system emptied in ad-
dition to the tank.
REFUELLING CAPACITY
To fill the tank completely, top-up twice after the first
click of the fuel delivery gun. Further top ups could cause
faults in the fuel supply system.

PROTECTING THE ENVIRONMENT
The following devices are used for reducing petrol fuel
engine emissions:
❍three-way catalytic converter;
❍oxygen sensors;
❍fuel evaporation control system.
In addition, do not let the engine run, even for a test, with
one or more spark plugs disconnected.
The following devices are used for reducing diesel fuel en-
gine emissions:
❍oxidizing catalytic converter;
❍exhaust gas recirculation system (E.G.R.)
❍diesel particulate filter (DPF) (for versions/markets
where provided).DIESEL PARTICULATE FILTER (DPF)
(for versions/markets where provided)
The Diesel Particulate Filter is a mechanical filter, inte-
gral with the exhaust system, that physically traps par-
ticulates present in the exhaust gases of diesel engines. The
diesel particulate filter has been adopted to eliminate al-
most all particulates in compliance with current/future le-
gal regulations. During normal use of the vehicle, the en-
gine control unit records a set of data (e.g.: travel time,
type of route, temperatures, etc.) and it will then calculate
how much particulate has been trapped by the filter.
Since this filter physically traps particulate, it should be
regenerated (cleaned) at regular intervals by burning car-
bon particles. The regeneration procedure is controlled
automatically by the engine management control unit ac-
cording to the filter conditions and vehicle use conditions.
There may be a limited increase in the engine idle speed
during the regeneration, a limited increase in fumes and
high temperatures at the exhaust. These are not faults;
they do not impair vehicle performance or damage the en-
vironment. If the dedicated message is displayed, refer
to the “Panel warning lights” paragraph in this chapter.
The catalytic converter develops high tem-
perature during operation. Do not park the
car on grass, dry leaves, pine needles or other
flammable material: fire hazard.

SAFETY175
With ignition key inserted, on MAR, even if
the engine is off, the air bags can activate
with the car stopped, if it is hit by another
vehicle. For this reason, children must never sit on
the front seat, even if the car is not moving. We re-
mind you that if the key is inserted and turned to
STOP, no safety device (air bag or pretensioner) is
activated following a collision; non-deployment in
such cases is consequently not the sign of a fault.
When the key is turned to MAR, the warn-
ing light “turns on, flashing for a few sec-
onds, to remind you that the passenger air
bag will activate in the event of a collision, then it
turns off.
Do not wash the seats with pressurized wa-
ter jets or steam (manually or at automatic
washing stations).
The front air bags deploy in the event of more
severe collisions than those required for de-
ploying the pretensioners. For collisions in
the range between the two activation thresholds,
pretensioner activation alone is normal.
Do not hook rigid objects to clothes hangers
and support handles.
The airbag does not replace seat belts; it in-
creases their effectiveness. Furthermore,
since front air bags are not deployed in low
speed collisions, side collisions, rear-end shunts or
roll-overs, the passengers are only protected by the
seat belts which must be fastened at all times.
