Problem outside temperature IX35 Facelift

Hello, at the current temperatures (-12 C) is shown with me e.g. 4 C. The temepratur rises and falls also. So the feeler “feels” what. I thought if it are the Fahrenheit values, but with Celsius as symbol. It could be true. If I switch to Fahrenheit, it calculates the current value. Has anyone ever had the problem? 2. Question: Can someone sgaen me, where the feeler in the engine compartment of the 1.6 Facelift IX35 is ? possibly with a picture ? Thanks
