Nope, that's why some people get CAN-View or Scan Gauge devices, to see what's really happening. Welcome to PriusChat!
A Scangauge 2 is the least coslty way to display RPM, Water Temp, voltage and more. I think Toyota dropped the ball on this one considering the MFD could have displayed the information. I guess they feel consumers are idiots and don't care about monitoring their engines.
