In the 2012 (and newer) North American version of the i-MiEV, here's what the manual says:It is possible to select the speedometer's display units -
1. Press the reset button to display the odometer
2. Keep the reset button pressed for two seconds or longer to change the display units from MPH to km/h or from km/h to MPH.
If I recall, this did not necessarily work on other models...
Edit: we have at least one thread for this - http://myimiev.com/forum/viewtopic.php?f=22&t=4770&p=42086
tout, I see from your previous posts that you've been trying to make this change on a JDM car imported to the UK. Did you ever import it? Do let us know how it turns out.
