Detecting a vehicle with the
system switched on
When the system is switched on by
turning ring Bto (+),any vehicle run-
ning in front of the car (within 130
metres) and along the running path
will be signalled to the driver on the
instrument panel display, with the fol-
lowing icon:
set distancex
set distancexset distance
x
This icons indicate the engagement
of speed and distance control with de-
tection of a running vehicle along the
running path, “picked” by the system.
The three different icons indicate the
three distance levels the driver can se-
lect.
When the external temperature is
less than 3 °C, the system will auto-
matically be set to maintain a greater
distance from the vehicle ahead, re-
gardless of the distance set.
If the system is temporarily switched
off by pressing the accelerator pedal,
the stored speed will flash on the in-
strument panel and the distance con-
trol icon will disappear (if shown on
the instrument panel display). Theicon (if any) indicating the vehicle de-
tected on the traffic lane will, on the
contrary, remain visible.
With system active and car speed ex-
ceeding 80 km/h, switching the left
direction indicators on to signal over-
taking will cause the distance from
the vehicle ahead (already “picked”)
to be automatically decreased in or-
der to facilitate the manoeuvre. If the
driver does not overtake within a few
seconds, the car will return to the set
distance.
If the Radar Cruise Control is active
and the braking power enabled for
the function does not ensure the
maintenance of the set distance from
the vehicle ahead, a sound and visual

DIESEL PARTICULATE
FILTER (DPF)
(2.4 JTD
20VCAE version)
The Diesel Particulate Filter is a me-
chanical filter, integral with the ex-
haust system, that physically traps
particulate present in the exhaust
gases of Diesel engines.
The diesel particular filter has been
adopted to eliminate almost totally
particulates in compliance with cur-
rent / future law regulations.
During normal use of the car, the
engine control unit records a set of
data (e.g.: travel time, type of route,
temperatures, etc.) and it will then
calculate how much particulates has
been trapped by the filter.Since this filter physically traps par-
ticulates, it shall be cleaned (re-
claimed) at regular intervals by burn-
ing carbon particles. Reclaiming pro-
cedure is controlled automatically by
the engine control unit according to
the filter conditions and the condi-
tions of use of the car. During re-
claiming the following phenomena
could take place: idling slight in-
crease, fan activation, slight smoke in-
crease, high exhaust temperatures.
These situations shall not be consid-
ered as faults and they do not affect
car performance and environment. Diesel particulate filter clogged
When the Diesel particulate filter is
clogged, the instrument panel warn-
ing light èwill turn on (on certain
versions symbol èis displayed). In
this case keep the car running until
warning light è(or symbol è) turns
off.

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
panelUwarning 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.

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 toAVV
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.

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.

EMERGENCY
START-UP
If the Lancia CODE system cannot
deactivate the engine immobilising
system, symbols YandUwill
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 STOPand
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. TheUwarning 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 MARtoAVV
(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.

Engine compartment
At the end of each winter season,
carefully clean the engine compart-
ment without directing the water jet
against electronic control units.
Have this done at a garage.
Detergents pollute water.
For this reason the car
must be washed in an
area equipped for the collection
and purification of the liquids
used while washing.
IMPORTANTThe car should
washed with the engine cold and the
ignition key at STOP. After washing
make sure that the various protec-
tions (e.g. rubber caps and various
covers) have not been damaged or
removed.INTERIORS
From time to time check that water
has not collected under the mats
(from dripping shoes, umbrellas,
etc.) which could cause the steel to
rust.
Never use inflammable
products like fuel oil
ether or rectified petrol
for cleaning inside the car. The
electrostatic discharges generat-
ed when rubbing to clean may
cause fire.
Do not keep aerosol cans
in the car. There is the
risk they might explode.
Aerosol cans must never be
exposed to a temperature above
50°C; when the weather starts to
get hot the temperature inside the
car might go well beyond that fig-
ure.
PLASTIC PARTS INSIDE
THE CAR
Use special products designed not
to alter the appearance of the com-
ponents.
IMPORTANTDo not use alcohol
or petrol to clean the instrument
panel.
CLEANING ALCANTARA
SEATS
Alcantara upholstery is easy to
clean. Follow the same instructions
provided for velvet upholstery.
