DescriptionThe headlamp beam orientation in accordance with the load is adjusted via the adjustment device located directly in the headlamps; it tilts them as appropriate in order to lower the light beam if the vehicle is particularly laden, and raises it when the load decreases.Two buttons, located in the control panel to the left of the steering wheel, allow the headlamps to assume 4 vertical positions from 0 to 3:position 0: one or two persons on the front seats, full fuel tank, car fully equipped and in running order;position 1: five persons;position 2: five persons with luggage compartment full (about 50 kg);position 3: driver and 300 kg load, all stowed in boot (full load).These 4 positions are produced using the '+' (the light beam is raised) and '-' buttons (the light beam is lowered).The set value is memorised and displayed on the instrument panel; when the dipped headlamps are switched off, the movement is disabled and the current position for the headlamp parabolas is maintained; when the dipped headlamps are switched on again, the display shows the headlamp alignment symbol with the number of the position memorized.This control logic described above is managed directly by the instrument panel node.The device is enabled only when the dipped beam headlamps are on.If there is a fault, the system positions the headlamps to prevent the drivers of vehicles coming from the opposite direction from being dazzled. The relay which controls the switching on of the dipped beam headlamps 2399172SeeE2011DIPPED HEADLAMPS also supplies the adjustment motors built into the headlamps; this relay for switching on the dipped beam headlamps is managed by the Body Computer: the relay is energized by enablement signals of ignition on (INT) and the stalk unit dipped beam control.
Functional description The dipped headlamps activation and AUTO function (earth) signal is sent to pin 2 of connector I of the Body Computer M1 from the steering column switch unit H5.2399172SeeE2011DIPPED HEADLAMPS . The Body Computer M1 controls the supply of the dipped headlamps sending an earth signal to the underdashboard control unit B2 - from pin 8 of connector F of M1 - which energizes the relay T1: this supplies pin 1 for the dipped headlamps F10 (left) and F11 (right). at the same time, the enablement for the adjustment motors is provided - pin 7 for the (left) headlamp F10 and F11 (right); Each circuit is protected by a junction unit B2 fuse F13 for the left headlamp and F12 for the right one. The headlamp adjustment control, located in the control unit to the left of the steering wheel H91, sends a modulated control signal, each time the '+' or '-' buttons is pressed, to the instrument panel E50, pin 14 of connector B. The internal logic for E50 manages the function, sending the actual control signal to the motors from pin 7 of connector A, whilst the enablement signal reaches pin 8 (dipped headlamps on). These control signal 'pass through' the junction unit under the dashboard - pin 1 of connector A of B2 and activate the motors - pin 6 for the (left) headlamp F10 and F11 (right).

Prepare the vehiclecomplete with spare wheel, tools, fluids, fuel reserve and driveron board. Check that the tyre inflation pressureis correct.Place the headlamp alignment switch inposition '0'.Position the vehicle on a flat surface,perpendicular to a screen or an opaque surface, 10 metres away,which contains the following lines. 1. V - V: vertical line corresponding to the plot of the plane ofsymmetry of the vehicle.2. C - C: plots of the vertical planes passing through the referencecentres of the lights clusters. 3. HC - HC: horizontal line corresponding to the height from theground of the reference centres for the lights clusters. 4. AC - AC: horizontal line 12 cm below the HC - HC line.5.
