I have a 2011 C300 and while driving today the yellow check engine warning came on. I pulled into an Autozone, had them check it, and was told that it was showing that I was low on antifreeze. This was my time to have to have a service engine light checked, so I took them for their word. I get home and read the manual and notice that there is a different light that comes on when engine coolant is low. Am I right, are did the light come on indicating a low level of antifreeze?

UPDATE...not sure exactly how to read the level.

Lets say I needed to add some antifreeze, can someone please help me in determining what I can use?

I'm wondering if it is it ok to continue driving until I can get to the dealership, which 2 hours away.

 

Attached is an extract from the MB manual

 

so as long as it is touching anywhere on this bar, while cool, shows that there is a significant amount?
