As per title, is the volume of the washer fluid tank in litres known/documented anywhere. 

 

Thanks. 

The capacity of the reservoir is 3 litres, or 4.7 litres in vehicles with the headlight cleaning system (in some countries, the reservoir capacity is 4.7 litres for both variants).

 

Extracted from page 273 of the user manual.

Thank you. 

 

I was expecting it to be tabulated in the technical data. Finally found it in my manual 2016 year, it's on page 196 in general maintenance section.
