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 on the panel beside the steering wheel allow the headlamps to be orientated 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.The set value is memorised and displayed on the instrument panel.The control logic described above is managed directly by the instrument panel node.The device is enabled only when the dipped beam headlamps are on. The relay which controls the switching on of the dipped beam headlamps 3023191SeeE2011DIPPED 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 beam activation signal is sent to pin 4 of connector D of the Body Computer M1 from the stalk unit H5 . The Body Computer M1 controls the supply to the dipped beam headlamps, sending an earth signal to the unit under the dashboard B2 - from pin 8 of connector F of M1 - which energizes the relay T1; this supplies the dipped beam headlamps and gives enablement to the headlamp adjustment motors F10 (left) and F11 (right). The headlamp adjustment control, located in the unit H10 , sends a control signal - when the relevant buttons are pressed - to the instrument panel E50 - pin 11 of connector B: the internal logic of E50 then sends (with dipped beam lights on) the supply to the motors from pin 5 of connector A, while pin 6 of connector A receives the reference signal.

Follow these precautions:769768768

5530B18


Follow these precautions.769On batteries with an opticam hydrometer,electrolyte level and battery charge status can be monitored qualitativelyby examining the indicator colour: a light, bright colour indicates low electrolytelevel: top up with distilled water;a dark colour without a green area in thecentre indicates that the electrolyte level is correct but chargeis low: recharge the battery; a dark colour with a green area in themiddle indicates that both electrolyte level and charge status arecorrect: no action is necessary. For further details, see DESCRIPTION ANDOPERATION - 5580.768Proceed as follows.Check the battery voltage without loadusing the test device recommended by the Service outlets (e.g. 'MICRO360'). Depending on the voltage values measured,which define the state of charge of the battery, proceed as follows:If the voltage without load is less than12.10 V, replace the battery (see op.). 5530B10).If the voltage without load is over 12.10V but less than 12.50 V, recharge the battery (see op. 5530B14).If the voltage without load is over 12.50V, the battery is efficient.If necessary, top up the electrolyte asfollows.Carefully remove the cap strip.Top up with distilled and deionized water,taking care not to allow electrolyte to splash out.768
