What is Low Washer Fluid Warning?

The symbol usually shows a windscreen with a fountain-shaped spray. In winter, use a washer fluid with antifreeze rated for local temperatures. Some cars share the same tank for the headlight washers and rear screen. Screen wash concentrate can be mixed with water to suit the season.

How it works

A float or level sensor in the reservoir switches the warning when the fluid drops below a set level.

Why it matters for your car

Plain water can freeze and crack the reservoir, pump or lines in cold weather. A dirty windscreen can be a legal offence in many countries and makes driving into low sun dangerous.
