Yep, that feature was discontinued on the last few late production 04s, never to be seen again. There's a short blurb on this in the model differences link online. I was also told by my dealer in 06 they upgraded the logic in the mpg computer to give slightly better mpgs and many called it the lie-o-meter in 06 and on. When I took the tour through the plant in Mishawaka, an engineer confirmed that for me. In the old days if you had an H2 they treated you like royalty on that plant tour.
