I have an 2006 Tiberon 06 GT, I had to change the batter today, When I replaced the battery the readout on the AC digital display had change to celsius instead of farinheit readout. Can someone tell me how to change the display back to Farinheit or do I have to bring it back to the service area. help needed.

 

hold the Amb Temp and the Temp down button at the same time it should change.
