    Is it possible to change the regional setting of fuel economy? I currently have l/100km set which is much less accurate than mpg or kmpl (=kilometers per liter). For example 4.1l/100km is 57.2 mpg and the next step 4.2l/100km is 55.9mpg. So mpg has 13 steps to represent the difference when l/100km has only one step.

    I know that MFD has inaccuracies (5-7%), but I'd still to change from l/100km to kmpl

    On the Western side of the Atlantic, I have not been able to figure out how to change MPG into l/100km. I find this odd, because I can change the speedometer on my car to indicate km/h.

    Unless someone else tells us how to do this, my guess is it can't be done--you have to make the calculation by hand.

    By the way, your note indicates that you've heard that in the US/Canada, there have been many complaints that the MPG readings that the Prius' computer gives are about 5% too high (about 2.4 mpg on my car), once you figure it out by hand. Is this a problem for you?

    Thanks!

    In Canada we can change from mpk to mph but not from k per 100 to mpg. H

    I would much prefer klpl rather than l/100.
    I believe this is the way the Japanese version is - too bad we can not change it.
    I calculate each tank using klpl:) and no matter which way we use nothing beats our Prius

    I would also like to know because it is much less precise in l / 100 km.

    IF you hold down the trip button while not displaying trip distance A or B, but the whole vehicle odometer, you'll switch from KPH to MPH or back. I did this accidentally after getting gas and wanting to reset my trip A and B (which you do by holding the same button while displaying the trip mileage) and not paying attention.

    Nobody knows how, because it can't be done. You can change mph/kmh, but not the fuel economy units. Hey, with 2016 Prius: you can't even change mph/kmh. I believe someone emailed Toyota and was told to take along a calculator, lol.
