After you play with the settings on the Prius Prime, how do you get the hybrid system indicator screen back on? It's staying on the settings screen. Do you have to drive for a few minutes or something?
Are you talking about Multi-information display (MID) setting screen (red arrow) and the Hybrid System Indicator? If that's the case, you have to toggle the display contents from the right side switch on your steering wheel. Hybrid System Indicator is under "Drive Information" (blue arrow) and you may have to toggle up-down to get to show it on the MID. Reading the manual will help you.
