Default Switch from Farenheit to Celsius

I just received my new 06 Prius yesterday with package #6 (no DVD GPS). Although I live in the US, I would like to switch the tempearture displays from Farenheit to Celsius degrees. It is simple to switch miles to kilometers, but I can't figure out how to change the unit of measure for the temperature. Does anybody know how to do that?

I think you probably have to do it the old fashioned way.

Begin by subtracting 32 from the Fahrenheit number.
Divide the answer by 9.
Then multiply that answer by 5.

Hmmm, I don't kow how your brain works, but mine isn't able to do those calculations in real time while driving

I am looking for a change in the default settings, I hope they just flip a switch at the factory for non US destined cars!

From what most of us can tell, Prii are localized for the market they are sold in. There doesn't seem to be a "switch", software or hardware which will magically move the car from one locality to another. Some would think that a metric/english switch on the dash would be standard, but there is only a mi/km switch that affects the speedometer only.

It has been said:
Hybrid drivers come in 3 flavors, greenie, techie and cheapie. Pick any 2.

I would suspect one of the settings in the diagnostic screens might change it, but I wouldn't fiddle with those unless I knew for sure.

So, when I decide to move to another country and take my Prius with me, a Toyota technician could reprogram the car for that country? Are there any Toyota technicians in the forums who could answer this question?

I don't know if the 2006 version changed anything, but the 2004 repair manual didn't document much about the diagnostic screen, other than the AVC DTCs. I suspect some of those settings are to configure the car for certain markets. If a tech could find the information, he'd probably have to get it from Toyota Tech Support HQ.

Default Any news on the Farenheit to Celsius settings?

Fred, I noticed the thread you started and am interested in exactly the same issue. However, I also noticed that you didn't get any practical advice for how to switch the readout in your Prius. Have you found out how since then?

Cheers,

So far I had no success in getting any kind of information about the feasibility of the idea. I am still hopeful though that someone knows how to do this.

For 2004/2005 (might have changed for 2006), you can get to a 2nd set of diagnostic screens by pressing INFO and flashing your taillights 3 times after getting to the first set of diagnostic screens. Careful with those settings though.
