Understanding the Vehicle
• a clearer light beam, with a cool white
tone that allows a better perception
of the contrasts thus making the night
vision more efficient and less tiring;
• a longer duration equivalent at least to
2
that of the vehicle;
• a reduced current consumption.
These functions positively affect
some vehicle management economy
aspects by eliminating/reducing the fuel
consumption.
The picture shows the increased
brightness of the low beam of standard
halogen headlights (A) compared to
those Full-LED (B) in the "motorway
beam" mode.
AFS Functions
These headlights combines the "Full-
LED" technology to the AFS (Advanced
Frontlighting System) adaptive
functions.
The system is able to process signals of
onboard systems and subsequently start
66
up four strategic steps in the following
situations:
• "motorway beam" that improves low
beam performance exceeding 110 km/h
(68 mph);
• "base beam" from 50 km/h (31 mph) to
110 km/h (68 mph);
• "town beam" that increases beam
spread form 0 km/h to 50 km/h (31
mph);
• "adverse weather beam" that reduces
glare on wet roads;
A fifth strategic step is the "tourist
beam" that can be manually activated
for example in countries with circulation
on the opposite side; in this case,
the function "Headlight Dip" must be
activated via the menu of MIA (refer to
"Functions of Settings Menu on MIA"
in section "Dashboard Instruments and
Controls" for more details).
The advantages offered by the AFS
system are perceived especially in case
of bad weather, fog and/or insufficient
road indications providing broader
illumination of the side zones, which
are normally left in the dark, and for
motorway driving.
This surely increases driving safety as
it offers less eye stress and increased
orientation for the driver and better
detection of other persons on the road
sides (pedestrians, bicycle riders and
motorcycle drivers). Furthermore, the
headlamps are suitable to prevent glare
to the other vehicles, providing optimal
lighting when driving the car in a country
with circulation on the opposite side.
The system assures better visibility
of the road surface when driving in a
curve, steering, or in the event of road
deviations, optimising vertical light
distribution according to the current
drive path.
The increased lateral illumination is
gained through a fixed bending light
or a cornering light (depending on the
market) elaborating information about
the steering angle, the vehicle speed and
the turn indicator.
The improved vertical illumination, in
case of fast acceleration and/or fast
deceleration, will assure the deeper
illuminated distance from the vehicle,
through a dynamical adaptation of
headlight vertical attitude.
NOTE:
• Each time the headlight system is
turned on, the headlights adjustment
will perform a self-adjustment cycle.
• "Adaptive Front Lights" function can be
turned on or off using the MIA system,
refer to "Functions of Settings Menu on
MIA" in section "Dashboard Instrument
and Controls" for further information.
