Twilight sensor
It is composed by an infrared led
sensor installed on the windscreen in
order to detect the changes of the
external light intensity of the car , as
a function of the light sensitivity set;
greater is the sensitivity, smaller is
the amount of external light neces-
sary to control the switching-on of
the exterior headlights.
It consists of two sensors: a global
sensor for evaluating environment
light intensity and a directional one
for evaluating light intensity in run-
ning direction in order to recognize
tunnels, dark road sections, etc.When ring Ais turned to AUTO
(automatic light switching on), and
the twilight sensor is malfunction-
ing, side/taillights and dipped beam
headlights are switched on regard-
less of the light intensity and the dis-
play on the instrument panel shows
the message “TWILIGHT SENSOR
FAULT – GO TO DEALER”.
Failure indication will stay on as
long as ring Ais turned to AUTO. In
this case it is recommended to deac-
tivate the automatic function and
switch on the lights manually; con-
tact a Lancia Dealershipas soon as
possible.Delayed light switching off
(“Follow me home” device)
This device allows the illumination
of the space in front of the car for a
length of time of 30 seconds (or a
multiple of 30) and is activated with
the ignition key at STOPor
removed.
This device is activated by pulling
towards the steering wheel and then
releasing the left-hand stalk within 2
minutes from when the engine is
turned off. At each operation of the
stalk, the staying on of the lights is
extended by 30 seconds, up to a
maximum of 210 seconds that corre-
spond to 7 stalk operations, then the
lights are switched off automatical-
ly.
Total set time (in seconds) is
shown on the instrument panel dis-
play for about 20 seconds.

101
IMPORTANTThis operation will
flash the main beam headlights.
Follow the Highway Code to prevent
being fined.
Direction indicators (fig. 96)
Move the stalk as follows:
up (position A) - to switch on the
right-hand indicators
down (position B) - to switch on
the left-hand indicators.
When direction indicators are on,
instrument panel warning light
Ÿor
Δwill flash.
The direction indicators return
automatically to neutral position
when the car straightens up.
IMPORTANTIf you want the indi-
cator to flash briefly to show that
you are about to change lane, move
the stalk up or down without click-
ing into position. When you let it go
it will return to its original position.RIGHT-HAND STALK
The right-hand stalk controls all
the washer/wiper controls.
Windscreen wiper (fig. 97)
This device can only work when
the ignition key is at MAR. The stalk
can be moved to 5 different posi-
tions:
0- Windscreen wiper off.
1- automatic operation. Turn ring
Ato this position to set the rain sen-
sor sensitivity.
2- Continuous slow.
3- Continuous fast.4- Fast temporary (unstable posi-
tion): when releasing the stalk it
returns to 0stopping the windscreen
wiper.
Windscreen washer (fig. 98)
Pulling the stalk towards the steer-
ing wheel (unstable position) oper-
ates the windscreen washer.
Keeping the stalk pulled, with just
one movement it is possible to oper-
ate the washer jet and the wiper at
the same time; indeed, the latter
comes into action automatically if
the stalk is pulled for more than half
a second.

Operating the windscreen washer
with the rain sensor activated (stalk
at position 1) the normal washing
cycle is performed at the end of
which the rain sensor resumes its
normal automatic function.
The rain sensor is switched off
when the key is turned to STOP. It
will not come on again at the follow-
ing engine start-up (key at MAR)
even if the stalk is at position 1. This
will avoid accidental activation when
starting the engine that could result
in dangerous situations (e.g. manual
windscreen washing, wiper blades
sticking due to ice and risk of dam-
aging the windscreen wiper motor).
In this case to activate the rain sen-
sor, just take the stalk to position 0
or2and then to 1again, or change
sensitivity (increase or decrease)
through knurled ring A.When the rain sensor is again acti-
vated in this way, at least one wind-
screen wiper stroke occurs, even if
the windscreen is dry, to signal the
occurred re-activation.
The rain sensor is located behind
the driving mirror in contact with
the windscreen and inside the area
cleaned by the wiper and it controls
an electronic control unit which in
turns controls the wiper motor.
At starting, the rain sensor auto-
matically provides to stabilize at
about 40°C temperature to elimi-
nate, from the control surface, the
possible condensate and to prevent
the ice formation. Turning the knurled ring A(fig.
100) it is possible to increase the
sensitivity of the rain sensor, obtain-
ing a quicker change from stationary
(no flick) when the windscreen is
dry, to second continuous speed
(continuous fast wipe):
■= low sensitivity
■■= medium sensitivity
■■■= high sensitivity
■■■■= max. sensitivity.
Rain sensor sensitivity level
increase (with sensor on) is indicat-
ed by windscreen wiper flick.

104
Rain sensor failure
In case of sensor malfunctioning,
intermittent wiping is activated with
the sensitivity level set manually,
regardless of the rain.
In this case it is recommended to
deactivate the rain sensor and acti-
vate continuous wiping (1
stor
2ndspeed); contact a Lancia
Dealershipas soon as possible. The rain sensor must be
deactivated (or key at
STOP) when cleaning the
windscreen (e.g. at service sta-
tions). The rain sensor must be
deactivated also when washing
the car manually or at automatic
washing stations.
The sensor rain is able to recognize
and automatically adjust itself in
the presence of the following partic-
ular conditions, which need a differ-
ent intervention sensitivity:
– impurities on the control surface
(salt, dirt, etc.)
– straks of water caused by worn
wiper blades
– difference between day and
night(the human eye is more dis-
turbed at night by the wet surface of
the glass).
In the event of ice on the
windscreen, make sure to
have disconnected the
device to prevent wiper motor
damages.

109
IMPORTANTRefuelling shall
always be performed with engine off
and ignition 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 inter-
nal system control logic and cannot
be considered as a system malfunc-
tioning.FLASH CONSUMPTION GAUGE
(fig. 107)
GaugeAshows the flash consump-
tion: to prevent excessively variable
values the gauge shows the average
consumption of the last minutes of
travel expressed in l/100 km (litres
per 100 km).
This is helpful for the driver for
learning the fuel consumption in
relation to the driving style.The gauge needle has the following
position:
– value 0 l/100 km with car sta-
tionary
– near value 2 l/100 km when the
car speed is between 4 and 20 km/h
and when releasing the accelerator
pedal during driving
– actual consumption value
(between 2 and 20 l/100 km) for
speeds exceeding 20 km/h.

INSTRUMENT
PANEL WARNING
LIGHTS AND
MESSAGES
On the instrument panel are set the
main warning lights. Certain warn-
ing lights with the relevant warning
messages are present also on the
instrument panel multifunction dis-
play.
Many indications/info are displayed
with a symbol only on the multifunc-
tion display with the corresponding
warnings for the driver.
IMPORTANTIndications may
vary according to the car version.GENERAL NOTES
Failure indications shown on the
multifunction display together with
buzzer sounding and warning light
(if any), are accompanied by spe-
cificwarning messages(e.g. “GO
TO DEALER”, “SWITCH OFF
ENGINE”, etc.). These indications
areconciseandcautionaryand are
aimed to suggest the prompt action
the driver must adopt when a car
malfunctioning appears. These indi-
cations, however, shall not be con-
sidered as exhaustive and/or as an
alternative to the specifications con-
tained in this Owner Handbook,
which shall always be read through
carefully and thoroughly. In case of
failure indication always refer to
the specifications contained in
this chapter.Failure indications displayed on
the multifunction display are divid-
ed into two categories: very serious
failures and serious failures. The
message and the warning indication
corresponding to very serious fail-
ures are displayed alternately for
few seconds. This “cycle” is repeat-
ed indefinitely and it stops any pre-
vious indication on the display. It is
displayed every time the ignition key
is turned to MAR, until the cause of
malfunctioning is removed. To stop
this “cycle”, briefly press (less than
two seconds) the trip meter reset
button. In this case the failure sym-
bol stays on the display in the cen-
tral area until the cause of malfunc-
tioning is removed.

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.

REAR SIDE BAGS
DEACTIVATED
(where provided)
The warning light comes on when
rear side bags are deactivated by the
relevant key switch.EOBD ENGINE
CONTROL SYSTEM
FAILURE
In normal conditions, turning the
ignition key to MAR, the warning
light turns on, but it should go off
when the engine has started.
If the warning light stays on or
turns on when travelling together
with message “ENGINE CONTROL
SYSTEM FAULT” on the multi-
function display:
Glowing steadily- means a fault
in the supply/ignition system which
could cause high emissions at the
exhaust, possible lack of perfor-
mance, poor handling and high con-
sumption levels.
In these conditions it is possible to
continue driving without however
demanding heavy effort or high
speeds. Prolonged use of the car with
the warning light on may cause
damages. Contact a Lancia
Dealershipas soon as possible.
The warning light goes off if the
fault disappears but it is however
stored by the system. FRONT PASSENGER
AIRBAG DEACTIVATED
The warning light comes
on when front passenger airbag is
deactivated by the relevant key
switch.

¬
If the ¬warning light
does not turn on when
turning the ignition key to
MAR or if it stays on when travel-
ling, (together with message on
display) this could indicate a fail-
ure in safety retaining systems; un-
der this condition air bags or pre-
tensioners could not trigger in the
event of collision or, in a restricted
number of cases, they could trig-
ger accidentally. Stop the car and
contact Lancia Dealership to have
the system checked immediately.
