I've had my 2016 Corolla for a few months and I still don't understand what the buttons on the left of the steering wheel are supposed to do. The center button does nothing but beep when I press it. The up and down buttons switch tracks. The left and right buttons seem to do nothing except skim through the song when you hold them down. This video says that on browse screens, the up and down arrows should move through the choices, and left and right move through headings, but they don't seem to do that on my car. Is this true of every model? Is there a setting I need to change?
