DEVICES FOR REDUCING PETROL ENGINE EMISSIONS
Three-way catalytic converter (catalytic exhaust pipe)
The exhaust system is equipped with a catalyst made up of noble metal alloys; it is housed in a
stainless steel container capable of withstanding the very high operating temperatures.
The catalyst converts the unburnt hydrocarbons, the carbon monoxide and the nitric oxides found
in the exhaust gases (though in small amounts, thanks to the electronic-injection ignition systems)
into non-polluting substances.
When functioning normally, the catalytic converter reaches high temperatures. For this reason do
not park the car over inflammable material (e.g. paper, fuel oil, grass, dead leaves, etc.).
Lambda sensors
The Lambda sensors detect the oxygen content in the exhaust gas. The signal sent by the oxygen
sensor is used by the injection system electronic control unit to constantly mix air and fuel in the cor-
rect proportion.
Fuel evaporation canister
As it is impossible to stop the build up of petrol fumes, also when the engine is not running, the sys-
tem traps them in a special container holding active carbon.
The fumes are sucked in from here and burnt while the engine is running.

OPENING THE TAILGATE
The tailgate can be opened from
the outside by pressing the remote
control button E(fig. 9), even when
the electronic alarm is on.
One single short pressure of the
button will switch the boot alarm
system off and release the lock: the
tailgate can therefore be opened
from the outside by pressing the
boot button. A prolonged pressure
(more than 1 second) of the button
will switch the boot alarm system off
and open the tailgate, which will
partially lift.
The opening of the tailgate is
accompanied by two direction indi-
cator flashes.When tailgate opening is actuated,
the alarm system disconnects the
boot sensor and the direction indica-
tors flash twice (except for the ver-
sions of certain markets).
When the tailgate is closed again,
press button D(fig. 9) to restore
locking and control functions; the
direction indicators will flash twice
(except for the versions of certain
markets).
If the tailgate is not open within 30
seconds after actuating the boot
unlock control, the tailgate lock will
be re-locked and the alarm system
will be reactivated.AUTOMATICALLY ACTUATED
FUNCTIONS
The system automatically controls
the following functions (settings that
cannot be modified):
– boot locking if, within 30 seconds
after boot unlocking, it will not be
opened;
– possible unlocking of all the door
locks, in case of impact with actua-
tion of the inertia switch;
– lock release and tailgate opening
(actuated by the button inside the
car);
– door opening/closing by the but-
tons inside the car;
– disconnection of all services when
the key is turned to STOP, exclud-
ing sound system, window regula-
tors, sunroof and internal lighting
until doors are opened;
– progressive switching on/off of
internal lights;
– light indication of boot open/
closed.

39
REQUEST FOR ADDITIONAL
KEYS WITH REMOTE
CONTROL
The receiver will acknowledge up
to eight keys with remote control. If
you ever need a new key with remote
control, go directly to a Lancia
Dealership, taking with you the
CODE card, personal identification
and the car ownership papers.ELECTRONIC
ALARM
The system consists of:
– radio-frequency transmitter
(built into the ignition key);
– radio-frequency receiver;
– electronic control unit with built-
in siren (the siren can be deactivat-
ed);
– volumetric sensors (which can be
deactivated);
– anti-lifting sensor (which can be
deactivated).
The electronic alarm is controlled
by the receiver and is switched
on/off by means of the remote con-
trol built into the key, which sends
the secret and variable code. The electronic alarm monitors:
– the illicit opening of doors, bon-
net and boot (perimetral protec-
tion);
– ignition switch operation;
– cutting of battery cables;
– moving bodies inside the passen-
ger compartment (volumetric pro-
tection)
– any abnormal raising/sloping of
the car.
IMPORTANTThe engine immo-
bilising system is governed by the
Lancia CODE system and is auto-
matically activated when the igni-
tion key is removed.

SWITCHING THE ALARM OFF
To switch the alarm off, press the
key button A(fig. 14).
The following actions will be car-
ried out by the system (with the
exception of certain markets):
– the direction indicators will flash
twice;
– two beeps will be heard;
– driver’s door or doors unlocking,
depending on the setting selected on
the CONNECT menu.
IMPORTANTWhen operating the
central door unlocking with the
metal insert of the key, the alarm is
not deactivated.VOLUMETRIC PROTECTION
Do not leave passengers or pets in
the parked car and completely close
the windows and the sunroof to
ensure the correct operation of the
volumetric sensors. Furthermore,
make sure that the doors, bonnet
and boot/tailgate are properly
closed.
To deactivate the volumetric
protection, press button A(fig. 16)
on the front ceiling light: when the
function is off, the button warning
light will flash for about 3 seconds
and then goes out.
Protection cut out stays on until
activating the central door opening
again.
IMPORTANTVolumetric protec-
tion shall be deactivated after about
1 minute from turning the key to
STOP. To deactivate the volumetric
protection after this period, turn the
key to MARand then to STOP
again.ANTI-LIFTING SENSOR
The anti-lifting sensor detects vari-
ations in slant to signal lifting or
partial lifting (e.g. to remove a
wheel) of the car.
The sensor can detect minimal
variations in cat trim along both the
longitudinal axis and the transversal
axis. Variations in trim lower than
0.5°/min. (such as, for example, a
slow deflating tyre) are not take into
account.
To switch the anti-lifting protec-
tion off, press button B(fig. 16) on
the front ceiling light: when the
function is off, the button warning
light will flash for about 3 seconds
and then goes out.To ensure correct opera-
tion of the volumetric pro-
tection system, before acti-
vating the alarm, check that win-
dows and sunroof (where pro-
vided) are perfectly closed.

42
IMPORTANTThe anti-lifting sen-
sor shall be deactivated after about 1
minute from turning the key to
STOP. To deactivate the anti-lifting
sensor after this period, turn the key
toMARand then to STOPagain.
Sensor cut out stays on until acti-
vating the central door opening
again.
WHAT TRIGGERS THE ALARM
OFF
The alarm will be triggered off in
the following conditions:
– if a door, the bonnet or the
boot/tailgate is opened;
– if the battery or electric cables
are disconnected or cut;
– if there is an intrusion in the pas-
senger compartment, e.g. a broken
window (volumetric protection);
– if an attempt is made to start the
engine (key at MAR);
– if an attempt has been made to
lift the car.According to the markets, the
alarm can operate the siren and the
direction indicators (for about 25
seconds). The intervention modality
and the number of cycles can vary
according to the markets.
A maximum number of acoustic/
visual cycles is foreseen in all cases.
After the alarm cycle, the system
returns to its normal surveillance
function.
INDICATIONS OF ATTEMPTS
TO BREAK IN
The alarm system indicates the
attempts to break in stored by the
control unit, through the lighting up
on the instrument panel display of
symbolYtogether with the mes-
sage “BREAK IN ATTEMPT”.
DEACTIVATING THE ALARM
To completely deactivate the elec-
tronic alarm (for example, if the car
is to be stored for a long period of
time), simply lock the car turning
the key in the lock.FUNCTIONS THAT CAN BE
DEACTIVATED
OR MODIFIED
The functions that can be directly
deactivated:
– volumetric protection, which can
be disconnected by means of button
A(fig. 16) set on the front ceiling
light: when the function is off, the
button warning light flashes for
about 3 seconds and then goes out;
– anti-lifting protection, which can
be disconnected by means of button
B(fig. 16) set on the front ceiling
light: when the function is off, the
button warning light flashes for
about 3 seconds and then goes out.

Recalling the “parking” position
of the external rear view mirror
on passenger side
To automatically recall the “park-
ing” position of the external passen-
ger rear view mirror, proceed as fol-
lows:
– with the car stopped and the igni-
tion key at MAR, engage the reverse
gear; the mirror will be automatical-
ly brought back to the previously
stored position .
If no “parking” position has been
stored, when engaging reverse the
passenger mirror slightly lowers
than normally to a preset position to
facilitate the driver during parking.
The rear view mirror will automat-
ically return to its initial position
after about 10 seconds from reverse
gear disengagement, or immediately
after exceeding a speed of 10 km/h
with forward gear. IMPORTANTThe “parking” posi-
tion memorisation and recall can
only be performed with ignition key
atMAR.
Automatic realignment
of external rear view mirrors
Every time the ignition key is
turned to MAR, the external rear
view mirrors automatically return to
the latest position reached and/or
recalled before removing the key.
This enables rear view mirror
alignment if, when the car is parked,
one of the rear view mirror has been
manually and/or accidentally
moved.COMFORT SEATS (fig. 47)
ButtonAon front Comfort Seats
enables to actuate the respective con-
trols separately. When pressing the
button of each of the two seats, the
respective CONNECT menu is actu-
ated; this menu makes it possible,
through its various options, to define
the heating levels and actuate venti-
lation, massage and the adaptive
function for each of the two seats.
The Comfort controls can also be
actuated by pressing the “Setup” key
of the CONNECT and then selecting
the “Seat Comfort” function.
To actuate these settings, refer to
the CONNECT supplement provid-
ed with the car.
IMPORTANTNever turn the pas-
senger massage function on when
the seat is not occupied since the
occupant sensor could activate (in
the event of an accident) the rele-
vant air bag.

The pretensioner does not require
any maintenance or greasing.
Anything that modifies its original
conditions invalidates its efficiency.
If due to unusual natural events
(floods, sea storm, etc.) the device
has been affected by water and mud,
it must necessarily be replaced.
The pretensioner can
only be used once. After a
collision that has trig-
gered it, have it replaced at a
Lancia Dealership Pretensioner
validity is written on the plate
located on the front left door post
near door hinges. The preten-
sioners should be replaced at a
Lancia Dealership as this date
approaches.After adjustment, always
check that the device is
anchored in one of the
positions provided. To do this,
with the grip released, exert a
further pressure to allow the
anchor device to catch if release
did not take place at one of the
preset positions. PRETENSIONERS
Your car is fitted with pretension-
ers on the front and rear side seats to
improve protection.
These devices “feel”, through a
sensor, that a violent crash is in
progress and rewind the seat belts a
few centimetres. In this way they
ensure that the seat belt adheres per-
fectly to the wearer before the
restraining action begins.
The seat belt locks to indicate that
the device has intervened; the seat
belt cannot be drawn back up even
when guiding it manually.
IMPORTANTTo obtain the high-
est degree of protection from the
action of the pretensioning device,
wear the seat belt keeping it firmly
close to the chest and pelvis.
Front seat pretensioners activate
only if front seat belts are properly
fitted into buckles.
A small amount of smoke may be
produced. This smoke is in no way
toxic and presents no fire hazard.

The front airbag (driver and pas-
senger) has been designed to protect
the occupants in the event of head-
on/angled collision of medium-high
severity, by placing a soft bag
between the passenger and the steer-
ing wheel or the dashboard.
In case of head-on collision, an
electronic control unit processes the
signals from deceleration sensor
and, when required, triggers the
inflation of the cushion according to
the severity of the collision.
fig. 89
L0A0070b
The cushion immediately inflates,
placing itself as a soft protective bar-
rier between the body of the front
passengers and the structure that
could cause injuries. Immediately
after, the cushion deflates.
The front air bag (driver and pas-
senger) is not a replacement for the
use of seat belts but rather a com-
plement. We recommend that seat
belts are worn at all times as pre-
scribed by legislation in Europe and
most other countries world-wide. A
passenger not wearing the seat belt
may crash into the bag before it is
fully inflated. In this case the protec-
tion is considerably decreased.
fig. 90
L0A0071b
Front air bags are designed to pro-
tect car’s passengers in front/angled
crashes and therefore non-activation
in other types of collisions (side col-
lisions, rear-end shunts, roll-overs,
etc…) is not a system malfunction.
For impacts against very
deformable or mobile objects (traffic
sign poles, heaps of gravel or snow,
etc…), rear impacts (e.g. car crash-
ing into the back), side impacts,
wedging under other vehicles or bar-
riers (e.g. under a truck or guard
rail), the airbag does not offer addi-
tional protection with respect to the
seat belts and may even be undesir-
able.
The fact that the airbag is not trig-
gered in these situations, this does
not signify a malfunction.

In the event of side collisions at low
speed, the restraining action of the
seat belts is sufficient and the airbag
is not inflated. Also in this case it is
of vital importance to wear the seat
belts since in case of side crash they
guarantee proper positioning of the
passenger and prevent the occupants
to be pitched out of the car in case of
violent crashes.
The front and rear side bag is not a
replacement for the use of seat belts
but rather a complement. We rec-
ommend that seat belts are worn at
all times as prescribed by legislation
in Europe and most other countries
world-wide.

SIDE AIRBAGS
(SIDE BAG - WINDOW BAG)
Purpose of the side airbags is to
increase passenger protection in the
event of a side impact of medium to
high severity.
Side airbags consist of two types of
instantly inflatable bags:
– the side bags housed in the front
seat bags C(fig. 88) and (where
provided) in the side stuffing of the
rear seats E(fig. 90). This solution
ensures that the bag is always in an
optimal position with respect to the
passenger, regardless of the seat
position;– the window bags, which are “cur-
tain” cushions located behind the
side coverings of the roof and cov-
ered by proper finishings such to
allow the cushion unfolding down-
wards; this solution, studied for the
head protection, allows offering the
best protection to the front and rear
passengers in the event of side crash,
thanks to the wide cushion inflation
surface.
In In the event of a side collision
the electronic control unit processes
the signals coming from a decelera-
tion sensor and, if required, fire the
bags.
The bags inflate instantly and act
as a soft protective barrier between
the body of the passengers and the
car door. Bags deflate immediately
afterwards.

Automatic switching on/off
When ring Ais turned to AUTO
and the ignition key is at MAR,
side/taillights, number plate lights
and dipped beam headlights will
turn on/off automatically according
to daylight intensity.
The twilight sensor sensitivity of
the automatic light on/off system
can be set, also when travelling,
through the 3-position ring B:
1- low sensitivity
2- medium sensitivity
3- high sensitivity.
IMPORTANTMain beam head-
lights can only be switched on man-
ually by moving the left stalk for-
wards.If main beam headlights
are on (left stalk for-
wards), they will turn on
automatically each time the twi-
light sensor makes the outside
lights switch on automatically. It
is therefore recommended to turn
off the main beam headlights (if
on), moving backwards the left
stalk, each time the sensor
switches off the outside lights.
Twilight sensor is not
able to detect the fog
presence, it is therefore
necessary to switch on the lights
manually, including the front and
rear fog lights.The driver is responsible
for the use of the lights
according to the light
intensity and traffic regulations
of the country where the car is
being driven. Automatic switch-
ing on/off must be considered
just as an help for the driver
since he/she must always switch
on/off the lights manually as nec-
essary.With automatic switching on acti-
vated and switching off control
given by the sensor, main beam
headlights go off followed after
about 10 seconds, by the side/tail-
lights.IMPORTANTWhen switching on
the headlights automatically, it is
possible to switch on the front and
rear fog lights. When headlights are
automatically switched off, the front
and rear fog lights (if previously
activated) will be switched off as
well. At the following automatic
switching-on, only the front fog
lights will switch on, whereas the
rear fog lights, if required, will have
to be switched on manually.
