Some instructions I'm trying to follow to test my 12-volt battery refer to the "MFD Button". Can someone please (NOT pls or pl) spell this out for me and let me know where to find it in a twenty-oh-eight (2008) model that has GPS? Thank you (NOT ty, tx, or thks) in advance (Not TIA).
There is no mfd button necessarily, the mfd is the multi function display, or touch screen in the center of the car. For the Gen III (2010 on) the display in the top of the dashboard is called the MID or multi information display.
Which instructions are you using? They should read "MFD Info button". Anyway, that would be the hardware "Info" button immediately to the left of the Multi-Function Display (the big touchscreen in the middle of the dash). If you don't have a copy of the 2008 Owner's Manual, get one. It's full of info you need to know.
