122KNOWING YOUR CAR
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”
chapter).
The goal of the system is to:
❍to keep system efficiency under control;
❍to signal a fault which causes emission levels to in-
crease;
❍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.
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.
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–ON 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.
“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–ON and the engine running; it
can be customised by the driver according to the driving
conditions.
IMPORTANT When turning the ignition key quickly,
complete power steering functionality may be achieved
after 1-2 seconds.

STARTING AND DRIVING181
Keep your speed down when snow chains are
fitted. Do not exceed 50 km/h. Avoid pot-
holes, steps and pavements and also avoid
driving long distances on roads not covered with
snow in order to prevent damaging the car and the
roadbed.
SNOW CHAINS
The use of snow chains should be in compliance with lo-
cal regulations.
The snow chains may be applied only onto the front
wheel tyres (drive wheels).
Check the tension of the snow chains after the first few
metres have been driven.
IMPORTANT Snow chains cannot be fitted to the space-
saver spare wheel. So, if a front (drive) wheel is punc-
tured and chains are needed, a rear wheel should be fit-
ted to the front of the car and the space-saving spare
wheel should be fitted to the rear. This way with two nor-
mal drive wheels, snow chains can be fitted to them to
solve an emergency.
CAR INACTIVITY
If the car is to be left inactive for longer than a month,
the following precautions should be followed:
❍park the car in a covered, dry and, if possible, well-
ventilated place;
❍engage a gear;
❍check that the handbrake is not engaged;
❍disconnect the negative battery terminal (for versions
with Start&Stop system refer to the paragraph
“Start&Stop system” in chapter “1”);
❍clean and protect the painted parts of the vehicle with
protective wax;
❍clean and protect the shiny metal parts using special
compounds commercially available;
❍sprinkle talcum powder on the rubber windscreen and
rear window wiper blades and lift them off the glass;
❍open the windows slightly;
❍cover the car with a fabric or perforated plastic sheet.
Do not use sheets of non-perforated plastic as they
do not allow moisture on the car body to evaporate;
❍inflate tyres to a pressure of +0.5 bar above the nor-
mal specified pressure and check regularly;
❍do not drain the engine cooling system.

USEFUL ADVICE FOR EXTENDING
THE LIFE OF YOUR BATTERY
To avoid draining your battery and make it last longer,
observe the following instructions:
❍when you park the car, ensure the doors, tailgate and
bonnet are closed properly, to prevent any light from
remaining on inside the passenger’s compartment;
❍turn off the roof lights, although the car does have an
automatic system for switching off internal lights;
❍do not leave devices (e.g. car radio, hazard lights, etc.)
switched on for a long time when the engine is not
running;
❍before performing any operation on the electrical sys-
tem, disconnect the negative battery cable;
❍battery terminals should always be perfectly tight-
ened.
IMPORTANT If the charge level remains under 50% for
a long time, the battery is damaged by sulphation, re-
ducing its capacity and starting attitude.The battery will also be more at risk of freezing (this can
happen as early as −10 °C). In the case of prolonged idle-
ness, refer to the paragraph “Car inactivity”, in chapter
“3”.
If you decide to install electrical accessories after the car
has been purchased which require a permanent electric
power supply (alarm, etc.) or accessories which have
a serious impact on the electrical balance, seek assistance
from a Lancia Dealership because their qualified staff will
suggest the most suitable Lancia Lineaccessori devices
and assess the overall electric consumption, checking
whether the car’s electrical system can cope or whether
a more powerful battery is required.
Since these devices continue to consume energy even when
the engine is off, they gradually run down the battery.
