The headlamp washer cleans the headlamp lenses as the windscreen is being cleaned.The headlamp washer function is managed by the Body Computer which automatically activates the headlamp washer, with the dipped or main beam headlamps on, when the windscreen washers are activated through the lever on the right of the steering wheel.The headlamp washer consists of a pump that sends detergent to a nozzle located in the bumpers. This in turn sprays a powerful jet on the headlamp.A timer activates the headlamp washer pump by means of a series of pulses lasting about half a second.
