W203 engine coolant?

[Starky]

Today I got a message on the car stateing the coolant was low

Does the car require a particular type of coolant? And is there a certain ratio of water to coolant?

Thanks.

Ratio is 50:50
Just get the coolant from mb dealership. That way it will match what is in.
Or if you plan to renew all the coolant then any decent antifreeze.
When I renewed my coolant I stuck to the MB stuff.
