GENERAL INFORMATION
Active front lighting system (AFL)
Active Front Lighting (AFL) is designed to
give the driver improved visibility under
varying driving conditions.
The illustration shows the light spread of a
vehicle NOT FITTED with AFL 1 and a
vehicle FITTED with AFL 2.
The main light source consists of
bi-functional (high and low beam) xenon
projector units.
The projector units are swivelled left or
right to improve the light spread on bends
in the road.
Bi-Xenon lights 3 provide significantly
improved visibility over halogen lights 4.
They also react dynamically in the vertical
plane to the vehicle’s braking or
acceleration to maximise headlamp
performance.
The units operate when the engine is
running and the master lighting switch set
to headlamps, see page 71, or AUTO, if
the ambient light has fallen below a preset
level.
The system takes inputs from the
vehicle’s road speed, steering angle to
determine the amount of horizontal
swivel. The amount of swivel is highest at
low speed, manoeuvring speeds and
reduces as speed increases.
If reverse gear is selected, the lamps
return to the central position and the
swivelling capability is disabled.
When the engine is started, the
headlamps can be seen to swivel as they
initiate a self-calibration cycle for a few
seconds.
