Note | Every fifth time the windscreen washer system is activated the headlights are also washed if the windscreen wiper lever on the steering wheel is pulled for at least 1.5 seconds - provided either dipped beam or main beam are switched on. |
| The „active time“ of the headlight washer system can be variably adjusted to between 0 and 12.75 seconds → Chapter. |
| Following installation work or on initial start-up of the headlight washer system, the system must be bled to ensure proper operation of the pop-up cylinders and spray jets → Chapter. |
| Fault detection and fault display: |
| The onboard supply control unit -J519- features self-diagnosis to facilitate fault finding. |
| For fault finding, use vehicle diagnosis, testing and information system -VAS 5051A- in „Guided fault finding“ mode. |
