From the settings menu (left/right options uses the right buttons on the steering-wheel), choose the far-right option. It's where you access speedometer & clock options. Scrolling down, you'll see "Meter Customization". Select that. "Simple/Split Screen" is the feature to edit. Choose "Split".
Many thanks! Also, do you know if there is a way to turn OFF the default so the car does not go into EV mode every time you re-start the car?
@bear15 It might be in the settings in the little display next to the speedometer. You might find something useful in this thread: Question on EV/EV Auto buttons | PriusChat
