OPENING FROM THE OUTSIDE
WITH THE KEY (fig. 193)
The boot lock is electrified: press
button Aon the tailgate to open it.
In an emergency (battery run down
or electrical system failure), the tail-
gate can be opened by fully turning
counterclockwise the key in the lock
and exerting at the same time a
slight pressure on the lower edge of
the number plate holder to reduce
the opening effort.
IMPORTANTIf the boot was
opened using the key, at closing the
automatic function will be deacti-
vated. To restore the automatic
function press button A.OPENING BY MEANS OF THE
REMOTE CONTROL
The tailgate can be opened from
the outside by pressing button A
(fig. 194) on the remote control,
even when the electronic alarm is on.
When the electronic alarm is on,
boot opening is accompanied by
double flashing of direction indica-
tors; boot closing is accompanied by
one flashing.
IMPORTANTIf the boot is opened
with the key when the electronic
alarm is on, the latter will not be
deactivated.If the electronic alarm is on, both
the volumetric protection and the
boot control sensor will be switched
off, and the system will emit (except
for versions of certain markets) two
beeps.

CLOSING THE BOOT
To close the bonnet,
lower it down until you lay
it on the lock, without
however slamming it. The lock is
electric and the bonnet will close
automatically. BOOT CEILING LIGHT (fig. 195)
The boot is lit by ceiling light A,
which switches on automatically
when the tailgate is opened.
The light switches off automatical-
ly when the tailgate is closed.
If the tailgate is left open, the ceil-
ing light will switch off after about
20 minutes: to switch it on again,
close and then open again the tail-
gate.LUGGAGE NETS
The boot is equipped with a fixed
net (fig. 196) set on the left side,
and (optional for versions/markets
where applicable) a mobile net.

These rings can also be used to fas-
ten the luggage net (optional, can be
purchased at a Lancia Dealership).LUGGAGE TRANSPORT -
IMPORTANT
The car is equipped with a system
that automatically keeps headlight
height steady on different loading
conditions. The adjusting system
works properly with the maximum
allowed loads: always make sure
that the load you are carrying does
not exceed the values specified in
chapter “Technical Specifications”.
When using the boot,
make sure the load you
are carrying does not
exceed the maximum allowed
weight (see the “Technical
Specifications” chapter). Also
ensure the items in the boot are
arranged properly and fastened
with straps to the specific hooks
to prevent them being thrown for-
wards and injuring passengers
should you brake sharply.Heavy loads which are
not securely anchored
could seriously injure
passengers in the event of an
accident.
If you need to carry
petrol in a jerry-can,
always comply with the
law regulations and use a certi-
fied can, which must be properly
secured to the fastening rings. In
any case, the risk of fire in case of
accident is high.

In an emergency, the flap can be
released by pulling wire B(fig. 216)
on the right-hand side of the boot
inside the service compartment.
To open the compartment flap,
turn the catch C(fig. 217) to 1using
the ignition key and lower it.IMPORTANT The airtight seal of
the cap may lead to a slight increase
of pressure in the tank. A hissing
sound when the cap is removed is
therefore quite normal.
The cap is equipped with a device
which fastens it to the flap so that it
cannot be misplaced D(fig. 218).
While you are filling up, fasten the
cap to the device inside the flap as
shown in the figure.
Do not put naked flames
or lighted cigarettes near
the fuel filler hole as there
is a danger of fire. Do not bend too
close to the hole either so as not to
breathe in harmful vapours.REFUELLING
To guarantee full tank filling, carry
out two refuelling operations after the
first click of the fuel delivery gun. Avoid
further topping up operations that
could cause damages to the fuel system.
IMPORTANTRefuelling shall always
be performed with engine off and igni-
tion key to STOP. If the engine is off
but the key is to MAR, a wrong fuel
level could temporarily be indicated.
This is due to the internal system con-
trol logic and cannot be considered as
a system malfunctioning.

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.

HEADLIGHTS
GAS-DISCHARGE (BI-XENO)
MAIN BEAM / DIPPED BEAM
HEADLIGHTS AND DYNAMIC
BEAM ADJUSTMENT DEVICE
These headlights, called Bi-Xeno,
use a lamp with a xenon-filled bulb,
both for the dipped beam and the
main beam headlights.
The main characteristics of this
type of headlights are:
– higher brilliancy
– higher light beam width and
adjustability
– lower consumption under work-
ing conditions
– longer bulb life.Each headlight is equipped with an
electronic control unit used to con-
trol supply voltage. Due to high bril-
liancy, bi-Xeno headlights require
the adoption of a dynamic beam
adjustment control system.
This system is controlled by an
electronic control unit operating at
two levels:
– constant headlight beam realign-
ment as a function of the car load
– dynamic headlight beam align-
ment to compensate car pitching
when running.Operation
Light is projected onto the road by
means of a spherical glass lens with
a large surface (70 mm diameter).
A deflector lifts and lowers, so that
light distribution is different for
both the main beam and dipped
beam headlights. The deflector is
electrically operated and the
mechanical lifting/lowering opera-
tion is performed real-time when
lights are switched.
The xenon lamp consists of a bulb
containing low-pressure xenon and
two electrodes.
To obtain light emission, an elec-
tric arc must be triggered between
the two electrodes and maintained.
Each headlight is equipped with a
control unit which:
– checks the voltage/current value
under working operation
– triggers the arc to the electrodes
and cause salt evaporation at
switching on.

Automatic dynamic beam adjust-
ment device
Bi-Xeno headlights require, due to
produced brilliancy, an automatic,
dynamic beam adjustment system.
This system is managed by an elec-
tronic control unit that controls the
actuators mounted on each dipped
beam headlight. Actuator control
depends on the processing of the sig-
nals from two orientation sensors.
This automatic dynamic beam
adjustment system provides the fol-
lowing advantages:
– it avoids dazzling the vehicles
coming from the opposite direction
– it stabilizes the illuminated area
so as to improve active safety.Headlight beam adjustment con-
trol unit
The control unit calculates the
instant car trim, by comparing the
signals from the orientation sensors.
A “correction” signal is sent to the
actuators to adapt light beam orien-
tation to the calculated car trim.
To avoid oscillation of the anti-
dazzling beam in case of particular
road surfaces (paved surfaces, dirt
roads, etc.) or abrupt movements of
the car caused by the driver (clutch
disengagement, gear change, etc.),
the control unit reduces the number
of corrections to be made on the
light unit.Fault indication
Anomalies in the operation of one
or several system components are
signalled by the lighting of symbol
6on the multifunction display,
together with message “HEAD-
LAMP INCLINATION ADJUST-
MENT SYSTEM FAULT”.
IMPORTANT In case of faults,
contact a Lancia Dealership.
In case of component anomaly or
voltage drop, the system controls in
any case system operation according
to the following logic:
– faulty front sensor: trim calcula-
tion is made by replacing the voltage
value read on the faulty sensor with
a stored, fixed value
– faulty rear sensor: the system is
switched to the safety operation
mode and keeps the headlights in a
preset position of maximum lower-
ing allowed by the light beam.

244
– Failed connection of actuators: if
the control signal is failing, the actu-
ators will be brought back to the
position of maximum lowering per-
mitted for the light beam
– control unit failure: depending on
the type of failure, the system can
remain in the position where it was
when the failure occurred, or set
itself for the maximum lowering per-
mitted for the light beam
– voltage drop: when voltage falls
below 9 V, the system remains in the
position where it was when the fail-
ure occurred.HEADLAMP ORIENTATION FOR
LEFT-/RIGHT HAND DRIVE
The car headlights are equipped
with Bi-Xeno lamps with high light-
ing power; therefore, when you trav-
el from a country with right-hand
drive to one with left-hand drive, or
vice versa, dipped beam headlight
orientation must be modified.
This operation is necessary to avoid
dazzling the vehicle coming from the
opposite direction, as well as to opti-
mize road edge illumination.To carry out this opera-
tion, contact a Lancia
Dealership.
When you go back to
your country of origin,
remember to have the
dipped beam headlight orienta-
tion modified again.
