The message and the warning indi-
cation corresponding to serious fail-
ures are displayed alternately for
few seconds. This “cycle” is repeat-
ed for about 20 seconds and then
goes off, but it comes on again every
time the ignition key is turned to
MAR. At the end of the cycle
(approx. 20 seconds) when pressing
briefly (less than two seconds) the
trip meter reset button, the warning
symbol is reduced to icon at the bot-
tom of the display and the screen
present before the failure returns on
the display.

fog lights. Press the button again to
switch the lights on after starting the
engine again or switching on the
dipped headlights or the front fog
lights.
IMPORTANTThe rear fog lights
may annoy the drivers following you
when visibility is good.Conse-
quently, use the light only when re-
quired.
IMPORTANTFollow the local pre-
scriptions governing the use of rear
fog lights. The rear fog light system
complies with EEC/ECE standards.

If, after an accident, you
can smell petrol or see
that the fuel feed system is
leaking, do not reset the switches
to avoid the risk of fire.Mechanical connections
of outside handles are
active only if the doors
are locked. In case the driver has
activated the central door locking
from the inside and, after an
accident, the inertial switch was
not able to activate the automatic
door unlocking as a result of bat-
tery loss or damage, it will not be
possible to reach the passenger
compartment from the outside.Anyway, door opening
from the outside depends
on their conditions after
the accident: if a door is distorted
it might be impossible to open it
even if it is unlocked. In this case
try to open the other car doors.
Before resetting the fuel
cut-off switch, carefully
check for any fuel leaks or
damages to the car electric devices
(e.g.: headlights).

If, after an accident, you cannot see
any fuel leaks or damages to the car
electric devices (e.g.: headlights) and
the car is in a fit state to continue its
journey, reset the fuel cut-off switch
and the circuit breaker according to
the following instructions.
Door unlocking in case of
accident
In case of accident with activation of
the inertial switch as a consequence,
door locks are automatically unlocked
to let rescuers reach the passenger
compartment from the outside.Resetting the fuel cut-off switch

Resetting the circuit breaker
Before resetting the cir-
cuit breaker, carefully
check for any fuel leaks or
damages to the car electric devices
(e.g.: headlights).Circuit breaker is located on the left
side of the boot, inside a box directly
set and connected to the battery pos-
itive terminal.
To reach the circuit breaker:
1) Open the tailgate.
2) Loosen knob A(fig. 130) and re-
move the battery cover B.
3) Press tabs A(fig. 131) and re-
move cover B.
4) Press button A(fig. 132) to reset
the circuit breaker.Initialising the control units of
the door locks, air conditioner
and ESP system
After resetting the circuit breaker, to
restore correct door locking, air con-
ditioning and ESP system, perform
the following operations:
1) Close the doors and the tailgate,
fit the key into the lock of one of the
front doors and perform a door cen-
tralised 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) Turn the steering wheel one
fourth turn at least (the car can be at
standstill but the engine shall be run-
ning) and start running the car for a
few metres in a straight line until the
ESP warning light
áis off.

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.

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.
