The vehicle is equipped with two dipped headlamps in the light
clusters.The dipped beam headlamps are switched on
through the steering column switch by turning the specific ring
to the position after the side lights.A special relay - in the underdashboard
control unit - controls the switching on of the dipped headamps
via two lines protected by special fuses.The relay for switching on the dipped headlamps
is managed by the Body Computer: the energizing of the relay is
activated by the go ahead signals with the ignition key in the ON position
(INT) and by the specific signal from the steering column switch
unit.The Body Computer also manages the 'dipped
headlampa maintenence' function: when the main beam headlamps are
on, the Body Computer keeps the dipped headlamps on.If the dipped headlamps and the main beam
headlamps are already on and the fog lights are switched on, then
the dipped headlamps are switched off. Similarly, if the dipped headlamps and the
fog lights are on and main beam headlamps are switched on, then
the dipped headlamps are switched off.In other words, with the main beam headlamps
and the fog lights on, the dipped headlamps are always switched
off.The dipped headlamps are activated automatically,
via the dusk sensor, if the AUTO function is set on the steering
column switch unit.The 'Follow me home' function is designed
to keep the dipped headlamps and the side lights on after the engine
has been switched off (key in OFF position) for a time of 30 seconds
or multiples thereof.Keeping the dipped headlamps on is signalled
by the side lights warning light in the instrument panel remaining
on.The funciton is switched on by operating
the flasher lever within 2 minutes: each time the lever is operated
the time the lights remain on increases by 30 seconds up to a maximum of
210 secs.Operating the flasher lever for longer than
2 seconds switches the function off; the function is also switched
off if the ignition key is turned to the ON position.
