What does CDI mean for Mercedes cars?

[rong_feng]

Hi everyone, i saw so far 2 or 3 mercedes cars (E class) with CDI on the right hand side on top of the rear lights. What does this mean? Is it a certain Elegance and luxury package or something? What is different about this model compared the other E classes? thanks a lot.
