Has anyone seen this reddish arrow/bar below the battery icon in the Hybrid System Indicator Display of a 2012 Prius 2? In the attached picture I drew-in the red arrow to show what I am referring to. It appeared when I was doing some normal, rush-hour-traffic driving-- at this particular time traffic was inching it's way up an incline-- nothing unusual as I drive this route all the time. It looked like a temp icon. It slowly disappeared as I made my way down the other side of the hill. Couldn't find this icon in the manual anywhere. Pretty sure it was not a reflection or artifact from lighting angle. Thanks in advance for any input and contributions.
