EOBD SYSTEM
The EOBD (European On Board
Diagnosis) system continuously
monitors the engine emission system
components. Furthermore, the sys-
tem warns the driver of deterioration
concerning the emission system
components by means of the instru-
ment panel warning light Ucoming
on with message “ENGINE CON-
TROL SYSTEM FAULT”.The objective is to:
– monitor system efficiency;
– warn when failures can increase
emissions over the threshold estab-
lished by the European regulations;
– warn of the need to replace dete-
riorated components.
Furthermore, the system is
equipped with a connector for inter-
facing with specific tools used to
read the error codes stored in the
control unit memory along with a set
of diagnostic and engine specific
parameters. This check can also be
performed by traffic controller
agents.Contact a Lancia
Dealership as soon as
possible if the instrument
panel Uwarning light either
does not come on when the key is
turned to MAR or comes on, with
fixed or flashing light, when trav-
elling together with message
“ENGINE CONTROL SYSTEM
FAULT”. Warning light Uoper-
ation can be checked by traffic
controller agents. Comply with
the regulations in force in the
country where you are travelling.
IMPORTANTAfter eliminating
the problem, your Lancia
Dealershipwill run a bench test to
fully check the system. In some
cases, a long road test may be
required.

247
The car is fitted with an
electronic brake force
distributor (EBD). The x
and >warning lights come on at
the same time on the multifunc-
tion display, together with mes-
sage “EBD SYSTEM FAULT”,
when the engine is running to
indicate that there is an EBD sys-
tem failure. In this case violent
braking may be accompanied by
early rear wheel locking with the
possibility of skidding. Drive the
car extremely carefully to the
nearest Lancia Dealership to
have the system checked.
If warning light x
comes on together with
message “LOW BRAKE
FLUID LEVEL”, on the multi-
function display, stop the car
immediately and contact a Lancia
Dealership. Fluid leakage will
compromise efficiency of both the
traditional brake system and the
ABS system.The system performance
in terms of active safety
must not lead the driver
to take unnecessary or unjusti-
fied risks. Always suit your dri-
ving style to the weather, visibili-
ty and traffic conditions.
Excessive use of engine
braking (gears tooshort
and limited grip) may
make the wheels slip. The ABS
will have no effect on this type of
skidding.
The maximum possible
deceleration always
depends on the available
road grip. Obviously, grip will be
considerably decreased in the
presence of snow and ice. In these
conditions, the braking space
will still be high, even with the
ABS.The coming on of the
>warning light on the
multifunction display,
together with message “ABS SYS-
TEM FAULT”, when the engine is
running, normally indicates a
fault in the ABS system. In this
case the braking system will still
be effective although without the
anti-lock device assistance. In
these conditions, EBD system
operation may also be reduced.
Drive the car extremely carefully
to the nearest Lancia Dealership
to have the ABS system checked.

HOW TO START PETROL
VERSIONS
IMPORTANTNever press the
accelerator before the engine has
started.
1) Ensure that the electric parking
brake is on (instrument panel warn-
ing light xon).
2) Ensure that electrical systems
and devices, especially high absorp-
tion ones (e.g. heated rear window),
are off.
3) On versions with manual gear-
box, set the gear lever to neutral and
press the clutch pedal fully down to
avoid the starter dragging the gears.4) On versions with electronic
automatic gearbox, ensure that the
selector is at Pand keep the brake
pedal pressed.
5) Turn the ignition key to AVV
and release it as soon as the engine
starts.
6) If the engine fails to start, return
the key to STOPand repeat the pro-
cedure.
IMPORTANTIf the engine does
not start at the first attempt, do not
keep turning the ignition key to
avoid damaging the catalyst.
Contact a Lancia Dealership.HOW TO START JTD VERSIONS
1) Ensure that the electric parking
brake is on (instrument panel warn-
ing light xon).
2) Put the gear lever to neutral.
3) Turn the ignition key to MAR.
4) Wait until the mwarning light
is off: the hotter the engine is, the
quicker this will happen.
When the engine is particularly hot
the warning light may come on so
quickly that it is impossible to notice
it.
5)Press the clutch pedal down to
the floor.
6) Turn the ignition key to AVV
immediately after the mwarning
light goes out. If you wait too long,
you will lose the benefit of the work
done by the glow plugs.

253
Remember that until the
engine has started, the
brake booster and power
steering systems will not work
and a greater effort will therefore
be required to press the brake
pedal and turn the steering
wheel. For cars equipped with
turbosupercharger in
particular, but generally
for any kind of cars, avoid abrupt
accelerations immediately before
turning the engine off. A quick
burst on the accelerator serves
absolutely no practical purpose,
wastes fuel and may damage seri-
ously the turbosupercharger
rotor bearings.EMERGENCY START-UP
If the Lancia CODE system fails to
recognise that code transmitted by
the ignition key (symbol Ytogeth-
er with message “VEHICLE PRO-
TECTION SYSTEM FAULT” on the
multifunction display) the emer-
gency start-up can be performed by
using the CODE card code.
For the correct procedure see chap-
ter “In an emergency”.
Before opening the lug-
gage compartment bonnet
to reload the battery or to
connect an auxiliary battery,
carefully read and comply with
the instructions contained in the
paragraph “If battery is to be dis-
connected” in the chapter “In an
emergency”. Never bump start the
engine (by pushing, tow-
ing or coasting downhill)
as this could cause fuel to flow
into the catalytic exhaust system
and damage it beyond repair.
IMPORTANTIf the engine turns
off while the car is running, the
Lancia CODE symbol Yand the
message “VEHICLE PROTECTION
SYSTEM FAULT” may appear on
the multifunction display when the
engine starts again. In this case
check that the warning light switch-
es off when turning the engine off
and on again with the car stationary.
Otherwise contact aLancia
Dealership.

263
Ignoring the above rules
may lead to fire. When functioning nor-
mally, the catalytic con-
verter reaches high tem-
peratures. For this reason, do not
park the car over inflammable
material (grass, dry leaves, pine
needles, etc.): fire hazard.
Do not allow anything to
be sprayed onto the cat-
alytic converter, lambda
sensor and exhaust pipe. Do not install other heat
shields and do not remove
those already fitted to the
catalytic converter and exhaust
pipe. Never run the engine with the
spark plugs disconnected even for
testing purposes. Do not warm up
the engine by letting it idle for a
while before moving off unless the
outside temperature is very low and,
even in this case, only do so for less
than 30 seconds.
If you have trouble starting, do not
keep turning the ignition key for
long periods. Be especially careful to
avoid bump starting the car by
pushing, towing or rolling downhill:
these are all manoeuvres that can
damage the catalytic exhaust sys-
tem. Use an auxiliary battery for
start-ups only.
If the engine begins to “lose its
smoothness” when travelling, con-
tinue your journey but reduce the
demands you are making on the
engine and have the car seen at a
Lancia Dealershipas soon as you
can.
When the instrument panel fuel
reserve warning light comes on, fill
up as soon as possible. A low level of
fuel can cause an uneven supply of
fuel to the engine with the inevitable
increase in the temperature of the
exhaust gas and serious damages to
the catalytic converter.

271
EMERGENCY
START-UP
If the Lancia CODE system cannot
deactivate the engine immobilising
system, symbols Yand Uwill
remain lit on the multifunction dis-
play together with messages
“ELECTRONIC KEY NOT
RECOGNISED” and “ENGINE
CONTROL SYSTEM FAULT”, and
the engine will not start. Follow the
emergency start-up procedure to
start the engine.
Read the whole procedure care-
fully before trying to carry it out.
If you make a mistake in the emer-
gency procedure you must turn the
ignition key back to STOP and
repeat the whole operation from the
beginning (step 1).
1) Read the five-digit electronic
code on the CODE card.
2) Turn the ignition key to MAR.3) Press and hold down the accel-
erator pedal. The warning light U
on the instrument panel will light up
for about 8 seconds, and then go
out. At this point release the acceler-
ator pedal and get ready to count the
flashes of the warning light U.
4) Count the number of flashes
that corresponds to the first figure of
the code on the CODE card, then
press the accelerator pedal and keep
it down until the Uwarning light
comes on for four seconds and then
goes out. Release the accelerator
pedal.
5) The Uwarning light will start
flashing again: after it has flashed
the number of times that corre-
sponds to the second figure on the
CODE card, press the accelerator
pedal to the floor and keep it there.
6) Do the same for the remaining
digits on the CODE card.7) Once the final figure has been
entered, keep the accelerator pedal
pressed. The Uwarning light will
light up for 4 seconds and then go
out. Release the accelerator pedal.
8) The Uwarning light will flash
rapidly for about 4 seconds to indi-
cate that the operation has been
completed correctly.
9) Start the engine by turning the
ignition key from MARto AVV
(without turning it to STOP).
If, however, warning light Ustays
on, turn the ignition key to STOP
and repeat the procedure from step
1).
IMPORTANTAfter an emergency
start, you should contact a Lancia
Dealershipimmediately as you will
have to repeat the procedure
described each time you want to
start the engine.

CHANGING
A WHEEL
Please note:
– the jack weighs 2.100 kg;
– the jack requires no adjustments;
– the jack cannot be repaired. If it
breaks, it must be replaced with a
genuine spare part;
– no other tool, part from the
ratchet wrench, can be fitted to the
jack.Change the wheel as follows:
1) Stop the car so that it is not a
hazard for other road users or your-
self when changing the wheel. The
ground should be as flat and firm as
possible.
2) Turn engine off and engage the
electric parking brake.
3) Engage first gear or reverse. On
versions with automatic gearbox
shift the lever to P.4) Open the boot.
5) Fold the boot carpet A(fig. 4).
6) Take out the warning triangle A
(fig. 5) and the tool kit B.
7) Release the locking device A
(fig. 6) and take out the jack holder
Band the spare wheel C, then place
them next to the wheel to be
changed.

DISCONNECTING THE
UNLOADED BATTERY
Should the discharged battery be
disconnected (to have it charged
again or to replace it) perform the fol-
lowing operations in the given order:
1) To open the boot from the out-
side, fully turn the key anticlockwise
in the lock (fig. 81), and at the same
time slightly press the lower edge of
the number plate holder to reduce op-
eration effort.
2) Remove the cover and disconnect
the battery terminals.
3) Fully charge the battery again or
replace it.4) Connect battery terminals and re-
assemble cover.
5) Depress push button A(fig. 81)
to restore normal lock operation.
6) Close boot normally without
slamming it down: lock electric servo
control will fully lock it.
7) Perform the initialisation proce-
dure of the door lock, air conditioner
and ESP system control units, here-
after described.INITIALISING THE CONTROL
UNITS OF THE DOOR LOCKS,
AIR CONDITIONER AND ESP
SYSTEM
Whenever the battery is connected
electrically or protection fuses are re-
placed, to restore correct door locking,
air conditioning and ESP system, per-
form the following operations (after
connection is performed or after re-
placing one of the fuses):
1) Enter key into the lock of one of
the front doors and perform a door
centralised opening/closing cycle.
2) Start the engine and turn on the
compressor of the conditioner, setting
a lower temperature value than that
of the environment and check
whether the led on the disconnection
push button of the conditioner com-
pressor òis lit.
3) Start running the car and drive it
for a few meters in a straight line (ac-
celerating), until the ESP warning
light is off
á. It is not possible to close
the boot when battery is
discharged or discon-
nected for the purpose of being re-
placed/ charged again: do not try
to close the boot by slamming it
down. The boot remains anyhow
hooked on and it must be re-
opened by turning the key in the
lock.

AIR CLEANER
The air cleaner is connected to the
air temperature and intake sensors
which send the electrical signals
required for the correct operation of
the injection and ignition system to
the control unit.
Consequently, the cleaner must
always be in perfect conditions to
ensure correct operation of the
engine and in order to contain con-
sumption and exhaust emissions.Replace the air cleaner
more frequently than
shown in the Service
Schedule if the car is used on
dusty roads.
The cleaner can be dam-
aged if it is cleaned and
consequently the engine
can be damaged.
DIESEL FILTER
(JTD versions)
DRAINING THE
CONDENSE
The presence of water in
the fuel feed circuit can
severely damage the
injection system and make the
engine misfire. Go to a Lancia
Dealership as soon as possible
when the cwarning light comes
on together with message
“WATER IN DIESEL FILTER” on
the multifunction display to have
the bleeding operation carried
out.
The air cleaner replace-
ment procedure is pro-
vided for indicative pur-
poses only. Have the operation
carried out at a Lancia
Dealership. Car safety can be
compromised if the cleaner
replacement procedure herein
described is not carried out cor-
rectly.
