Installed features?

[Mel897]

Is there a way to determine what features are installed on a purchased used vehicle.? I'm reading the owners manual and it seems most feature references are "(If equipped) ". I could get through reading this manual if I could skip over what does not apply. On the other hand, I would sure like to learn about what I do have.

I apologize for asking a newbie question but I searched several ways for a clue.
