ADAPTIVE FRONT LIGHTING
SYSTEM
The adaptive front lighting system (AFLS) is designed
to give the driver improved visibility under varying
driving conditions. The main light source consists of
bi-functional (high and low beam) xenon projector units
that are swiveled left or right to improve the light spread
on bends in the road. The illustration shows the light
spread of a vehicle fitted with AFLS (1) and a vehicle
not fitted with AFLS (2).
Bi-Xenon lights (3) provide significantly improved
visibility over conventional halogen lights (4).
The projector units also react dynamically in the vertical
plane to the vehicle’s braking or acceleration to
maximize headlight performance.
The units operate when the engine is running and the
master lighting switch is set to headlights, or AUTO (if
the ambient light has fallen below a preset level). When
the engine is started, the headlights will swivel for a
few seconds as they initiate a self-calibration cycle.
The system takes inputs from the vehicle’s road speed
and steering angle to determine the amount of horizontal
swivel. The amount of swivel is highest at low and
maneuvering speeds and reduces as speed increases.
If reverse gear is selected, the lights return to the central
position and the unit’s swiveling capability is disabled.
Static Bending Lights
Additional lighting comes from the cornering (static
bending) lights, which are angled outwards from the
center line of the vehicle. These lights broaden the beam
of the headlights when cornering during normal night
driving. The illustration shows the light spread of a
vehicle not fitted with static bending lights (1) and a
vehicle fitted with static bending lights (2).

The system switches on the light on receipt of an input
from the vehicle’s direction indicator cancel switch,
activated by the turning of the steering wheel. The light
is switched on regardless of whether the direction
indicator is active or not. Only the light on the same
side as the direction of the turn will illuminate. The
lights only operate when the ignition is ON.
NOTE: Excessive rotation of the steering wheel while
the ignition system is in the OFF position may cause
incorrect calibration of the static bending lights (in
extreme situations, the lights may operate earlier than
normal). The lights are automatically recalibrated within
30 seconds of the start of a drive cycle.
