Intelligent lighting
I think the factory lights say Intelligent Lighting System on the headlight assemblies. If you have those the previous owner may have added them without doing a full upgrade to all the needed sensors and/or coding. Otherwise there would be no such message if you have the base headlights.
I think the ILS package includes the headlamp washer. My way of determining if the ILS is an aftermarket add on. Correct me if I'm wrong!

You should be able to tell by looking at the lights as you turn. They will ever so slightly bend around the curve for you. Also when you start your car the headlghts will self check themselves by going down and out. If your lights do not move when you start your car I say you don't have it.
You need to change your main battery , cheap insurance . before it desactivate your rain , light sensor , eco start & stop automatic lights inoperative . Make sure to buy a genuine Mercedes battery .

The only time I've seen ILS on a W204 C-Class is with the C350s. But I rarely see them on the road.

Sorry OP, not trying to hijack this thread. Just thought you could pick something with regards to your ILS issue. Good luck!
