Changing The Temperature Units In The EATC Display
WARNING: This page is about a different car, the 2004 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
With the EATC switched on, pressing both BLOWER and RECIRCULATED AIR buttons at the same time for at least 2 seconds causes the display mode to switch from degrees Centigrade to degrees Fahrenheit.
