Yeah, I spend three weeks reading it in the bathtub with a cigar before I took delivery.

There's a lot of stuff in there to know.

Here's another hint. The manual is pretty big and has a lot of stuff in it of little or no importance. So I do not keep the manual in the X5. Instead I printed a few of the important pages I might need while in the vehicle, like the manual sunroof instructions, manual transmission release, towing instructions, instrument panel waring light IDs, etc. onto plain paper, and just keep the folded-up pages in the glove box.
