Yes, I am sure, it is not in the manual. That is all they gave me with the car.

I am not looking to turn this into some type of "them against us" thing (I am an attorney by trade, I get enough of that). I just wanted to know what the various services are for each letter. To be honest, I do not trust dealership service departments, as they have screwed up on me too many times. Plus, where I live (outside of chicago) when people ask questions like that, they give dumbed down answers, as most people who drive benzes around here would not know a belt, plug, or hose if it hit them in the head.

I prefer to do the work myself as I have always done with all my cars. This is just the first time the info was not in the manual.
