Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Headlight Washer System: Notes
The headlight washer system is switched on during the first wash cycle after terminal status "terminal R ON" and "lights ON". Activation is then suppressed for 7 min. The headlight washer system is activated if the windscreen washer system is operated 5 times within the 7 minutes.
In response to the request from the junction box electronics, the headlight washer system is switched on by means of a relay in the distribution box.
The headlight washer system is no longer activated if the washer fluid level in the washer fluid reservoir is too low. The junction box electronics receive the signal from the washer fluid sensor.
The headlight washer system is not actuated either if obstruction of the wipers is detected.
