Outside temp gauge. on 2008 Mercedes-Benz S600

The outside temperature as shown in car is way too high. Is there a reset button somewhere? Thanks

You have to place the outside temp sensor where it belongs. Usually it is behind your front bumper. It might have fallen or maybe the tab that holds in place is broken and it is showing the wrong temperature
