Cruise Control icon
On the 2012 Focus ICE the circular icon with the arrow indicates that the cruise control is turned on. When a speed is set the the speed is shown as numbers next to the icon. When you step on the brake or disengage the cruise control a line is drawn thru the numbers so you can see what the speed will be when you reengage the control. There is space for the numbers on the EV my guess is it just didn't get implemented.
