If it can be done, we don't know how to do it. It has been asked before, but nobody knew. There is a sequence to change the seatbelt warning behavior, that sets an option in the cluster, there is probably a way to do other things also, but it's like a cheat code in a video game, and nobody has found it yet.THere are places that can program the instrument cluster, I looked at one when I was replacing my 03 red cluster with a 04 red and white one, and I needed to make the new odometer match the old one. There is a company called SPECMO
http://www.specmo.com/Conversions/Conversions.asp they say they can do it. I have no idea what it would cost, and what turn around time they offer. WHen I called them about setting an odometer, they sounded pretty responsive, but I have never actually had an business with them, so I can't vouch for themIf you do find some sort of special combination of switch pressing and key turning that can toggle between english and metric units, you better post it up here!The odometer will only count up to 299,999 and wil not roll over, it will just stop at 299,999. kms or miles doesn't matter, 299,999 of either is the max it will count. Since 299,999 miles is about 480,000 kms, an english clustered vibe will go a lot further than a metric clustered vibe So are you importing the car for your own use, or are you a reseller of some sort?
