Submenu Display Area (Optional IPC Only)
WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The optional IPC provides an area in the upper RH corner of the LH message center display that is used to indicate the level of submenus that is currently displayed. The number of boxes shown depends on the number of submenu items that are available for selection. The box is filled in (darkened) to indicate the current selection. For example, if there are 4 boxes shown that means that there are 4 submenu items available to select from using the LH steering wheel (message center) right/left button. If the third box is filled in, that means the selected display is the third submenu or 3 button presses to the right.
