I have Prius 2007 one sign in speedometer is blinking its look like a "key inside car" it's blinking after switch off all time What does its mean and how it remove ?
It is the Hybrid system immobilizer indicator Blinking means it is set to immobilize the car if the door is opened without a key. http://www.toyota.com/t3Portal/document/om/OM47568U/pdf/02-01.pdf (Page 4 of the PDF, Page 22 of the paper manual) There is more detail on setting, resetting, and canceling the system on Page 28 of the PDF, or Page 46 of the paper manual.
When was the last time the FOB battery was changed? In a darkened room how bright is the little red LED lit? Should be real bright.
