What means yellow warning light in the Peugeot 405 instrument panel below Tachometer in the bottom on the left and where you can get information about instrument panel readings?

That light is the "water in diesel fuel" light. Ive had it on in my 405 diesel too. Does it look like a bucket with water in it with lines on the side? yellow?
