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.

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.

SAFE DRIVING
In designing THESIS, LANCIA has
made every effort to come up with a
car able to provide driver and pas-
senger with top-class levels of safety.
Nevertheless it is always the behav-
iour of the person at the wheel that
determines road safety.
Below you will find some simple
tips to help you travel in safety
under different conditions. You will
no doubt be familiar with many of
them already, but it will be useful to
read them all carefully.
BEFORE GETTING BEHIND
THE WHEEL
– Make sure all lights, including
the headlights, are working proper-
ly.
– Adjust the position of the seats,
steering wheel, driving and door
mirrors properly for the best driving
position.
– Carefully adjust the head
restraints so that the back of the
head and not the nape of the neck is
supported. Make sure that nothing (mats etc.)
gets in the way of the pedals when
they are pushed down.
– Make sure that any child
restraint systems (child seats, carri-
ers etc.) are properly fixed on the
rear seat.
– Place any objects in the boot in
such a way that they cannot be
thrown forwards in the event of an
accident.
– Do not eat a heavy meal before
travelling. Light eating will help
keep your reflexes prompt. Above
all, do not have anything alcoholic to
drink.
Periodically, remember to check:
– tyre pressure and conditions;
– engine oil level;
– coolant level and cooling system
conditions;
– brake fluid level;
– power steering fluid level;
– windscreen washer fluid level. WHEN TRAVELLING
– The first rule of safe driving is
prudence.
– Prudence also means putting
yourself into a position where you
can predict wrong or imprudent
behaviour from other drivers.
– Stick closely to the rules of the
road in the particular country where
the vehicle is being driven and,
above all, do not exceed speed limits.
– Ensure that, besides yourself, all
the other passengers in the vehicle
have their seat belts fastened, that
children are sitting in the appropri-
ate child seats and any animals in
the car are placed in suitable com-
partments.
– You should be physically fit and
mentally alert before setting out on
long journeys.

257
– Keep a greater safety distance
from the cars in front of you than
during daylight hours: it is hard to
judge how fast other cars are going
when all you can see are their lights.
– Only use main beam headlights
when you are driving outside town
and when you are sure they do not
annoy other drivers.
– Dip your headlights as soon as
you see cars coming in the other
direction and pass them with the
headlights dipped.
– Keep all lights clean.
– Be careful of animals crossing the
road when driving in the country.
DRIVING IN THE RAIN
Rain and wet road surfaces spell
danger.
All manoeuvres are more difficult
on a wet road because the grip of the
wheels on the tarmac is greatly
reduced. This is why braking dis-
tances are much longer and road-
holding is lower.Here is some advice for driving in
the rain:
– Reduce speed and maintain a
greater safety distance from the cars
in front.
– If it is raining particularly heavi-
ly, visibility is also reduced. In these
cases, switch on the dipped head-
lights even if it is still daylight so you
can be seen more easily.
– Do not drive through puddles at
speed and hold on tightly to the
wheel if you do: a puddle taken at
high speed might cause you to lose
control of the car (“aquaplaning”).
– Move the ventilation controls to
the position for demisting the win-
dows (see the section “Getting to
know your car”), so to avoid visibil-
ity problems.
– Periodically check the condition
of the windscreen wiper blades. – Do not drive too many hours at a
time but stop at intervals to stretch
your legs and recoup your energy.
– Make sure the air in the car is
being changed continuously.
– Never coast downhill (i.e.: with
the engine off): if you do, you lose
the aid of engine braking and power
brakes so that braking requires
greater effort.
DRIVING AT NIGHT
There are the main rules to follow
when you are driving at night.
– Drive especially carefully: it is
harder to drive at night.
– Slow down especially if the road
is not lit.
– At the first signs of sleepiness,
stop: continuing would be a risk for
yourself and everybody else. Only
start driving again when you have
had enough rest.
