Luckily, I was approaching the roundabout of a service station so I could pull straight in.

Water lost, but no overheating as I caught it straight away & switched off the engine.

Van taken to garage, new belt fitted & it was good to go.

So how did I know? On the Mercedes up flashed the display with the classic outline of a radiator, indicating LOW coolant level, rather than having to wait until another indicator to indicate OVERHEATING.

Rather like the low windscreen wash message, there's similar in the coolant circuit.

Now why didn't Volvo include similar when building these cars?

Or why not retrofit one - TBH I'd never considered it until recently myself.

On Volvo B7R buses the low coolant light works too well a lot of the time, comes on when it feels like it, even with a full tank!
