W212: 2009 Top up coolant, See owners manual.

[anyweb]

got that message yesterday and this morning also, so I went and bought a liter of 50/50 coolant (blue), i'll add it once the engine cools after this morning's drive, however should I be worried about this message, i googled a bit and found another person with the same car and in that thread they were referring to head bolts and hydrolock possible issues, all scary stuff, i guess i should get worried if after adding the replacement coolant the message doesn't go away...

your thoughts are appreciated as always..

Keep an eye on it, I have the same thing with my car with the same engine in, could be a coolant leak which will probably be the water pump

so i added one liter of coolant yesterday and the message has not come back, hopefully it was just in need of a top up and that'll be the end of it, but i'll keep an eye out and report back if it changes, cheers

Mine is leaking from the top hose where it joins the thermostat
