Generally speaking those are set in the factory and can't be changed. But I'm not sure if the USA and Canada share the same market build, in which case you may be in luck. But I'll leave it to the USA/Canada brethren to confirm.
If the speedo display works the same as the EU model, there is a MPH/km/h button at the bottom left of the MDF, but that is all it changes everything else stays in old school units.
Thanks alot. I need more than that... the speedo is changeable but other stuff mpg and tempreature are not I think I have to take on thim Posted via the PriusChat mobile app.
