Question

DentroTest · Accepted Answer

The windshield washer system reservoir must be filled up to the maximum level mark to ensure the maximum visual cleaning capacity while driving. It is essential to use a specific fluid formulated for windshield washers, which contains detergent and antifreeze additives. Ordinary tap water must be avoided, since limescale and mineral impurities can clog the lines and the nozzles (ejectors), in addition to having no protection against frost.
