Bought a 4runner that originated from Ontario, temps in Celsius
 

So I bought a 2000 4runner limited. Carfax shows it came out of Ontario down here into the states. This is my first car so go easy if my terms are not correct

The heat display shows everything in Celsius. I was wondering if there was a way to change this without having to replace the entire thing, if someone knows how to reprogram it or something easy I can do I would appreciate it.

Thanks
