I believe the buttons are different for newer years. My 2012 has buttons on the left side of the steering wheel as shown in the thumbnail photo. The buttons I use to access the extended menus are the up and down arrow buttons (bottom two on left side). You have to be in the screen showing the outside temperature to start the access procedure. If you're not in that screen, press the lower right button on the left side repeatedly until you are. Once in the temperature display screen, hold down the up arrow key for 10 seconds (I find the thousand count works great - as in one one thousand, two one thousand, three one thousand...), then release and immediately hold the down arrow for 5 seconds. When you let go of the down button after the 5 count, you should be in the extended menus. I sometimes have to try this a few times to get it right. Then, use the up or down buttons to get to the different screens.
Note that I've only ever 'looked' at the info in these screens, never changed anything, so I can't speak to the method of changing values.
Hope this helps.
