I had this same error. It has to use a special Mercedes Coolant (otherwise it won't last the 10+ year service interval). It is mercedes spec 325.3 coolant (blue). If you don't want to use mercedes brand, all of these coolants meet 325.3 spec, but I would still use oem:

But you can use 325.0 (orange/yellow) for a minor top-up. Technically, you can even just fill it up with distilled water since that is mainly the part that has evaporated.
EDIT: My dealer even offered to do it free, but I didn't want to wait the almost 2 weeks for a service apointment.

Now for the meat: MB fluid to specification 325.0 is the ticket. But there are two easy get, Mercedes own label and Zerex G-05 (both totally compatible for fillup mix or fluid replacement).
These are meant for change not further than after 150,000 miles or 15 years in cars with a gel pack (see User's Manual and Maintenance Schedule). The gel pack is long lasting (~300,000 miles) and maintenance free. Otherwise these antifreeze solutions (in distilled/demineralized water) should be replaced every 50,000 miles or 5 years maximum (in opposition to standard 20,000 miles/2-years lasting products).
The reasons have to do with additive depletion, of antioxidants and corrosion protectors, as well as system components materials and functional flow protectors.

The color of the antifreeze solution is just coloring that keeps the solution compatible even after a fill up of mixed colors. No worries.
