The PDF is an X5 training document. For instance, the alarm system description is clearly X5 specific although the design concept is shared with the E39. So I wouldn't rely on every detail being present in an E39.

I've never seen any mention of a state of charge warning for the key battery in the E39. There is no mention of it in the E39 owner's manual.
