3233787 - E2011 DIPPED HEADLAMPS - Description ( Xenon Gas headlamps)

Description

The vehicle is equipped with two GAS DISCHARGE headlamps.The electronic circuitry in each of the two headlamps switches the software on and off at the appropriate times and, in accordance with international regulations, the gas discharge headlamps.The system consists of an ignition system and ballast for each lamp which are activated when the dipped headlamps function is requested.The left headlamp is the Master control unit while the right acts as a Slave unit.The master receives the command for the dipped headlamps and the vehicle speed from the potentiometers on the wheel axles. According to the input, the switching on of the left front headlamp (dipped headlamps) is controlled and likewise that of the right headlamp via the serial line.The dipped beam headlamps are switched on through the steering column switch by turning the specific ring to the position after the side lights.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 and/or PARK) for a time of 30 seconds or multiples thereof.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.A special relay - on the left hand side, under the dashboard - keeps the dipped headlamps on with the main beam headlamps on.The circuit is protected by two fuses, one for the right hand headlamp, one for the left hand headlamp.The dipped beam circuit also enables the rear fog lamps for operation.
