Plain water on its own is not sufficient for the windscreen washer system.
Engine compartment: Windscreen washer container
The container for the windscreen washer v contains the cleaning fluid for the windscreen and the headlight washer system. Container capacity: page 293.
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.
• Never put in radiator anti-freeze or other additives.
• Never use washer fluid which contains paint thinners or solvents as it can damage the paintwork.
