I saw this in the owner's manual too and called the dealer about it who referred me to one of their technicians. He said that, unfortunately, this was a mistake in the owner's manual because the TCH does not have seat and side view mirror memory.
I didn't pursue it any further; I hope that he was wrong and that someone in this board finds out for sure if this can or cannot be done.
Or maybe we all accidently got the 2008 owners manual as this will probably be one of the new features in the next model year.
