Plain water on its own is not enough to clean the glass properly. It is therefore advisable to add a suitable washer fluid additive (with wax solvent) to the water. A washer fluid with freeze-resistant additive should be used in winter.

Caution
Х Never put in radiator anti-freeze or other additives.
Х Never use washer fluid which contains paint thinners or solvents as it can damage the paintwork.
