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 A is 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 A is 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 Dealership as 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 STOP or
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.
