The headlight washers spray the headlights after every fifth spray on the windshield, provided that the dipped beam or high beam headlights are on, after pulling the handle to the position (5), namely the duration of approx. 1 sec.
When washing the headlights, the jets protrude from the bumper under the pressure of water.
Dirt stuck to the headlights (like insect remains) - but remove from glass headlight splitters at regular intervals (e.g. when refueling), by cleaning them manually. To ensure the correct operation of this equipment also in winter, regularly remove snow and adhering ice from the jets with a defrost spray.
