    I have an 07 Prius that will not start. It has a red triangle light, CEL, and a few others. Gas engine will not start. It will not shift into neutral. I have a steep driveway and cannot get my other cars out. Any ideas on where to start?

    Tried to disconnect battery to see if resetting would work. Did not. Also tried the orange fuse on the hybrid bank. Didn't work either.

    Make sure the 12v battery is good, if over 5 years old, just buy a new one.

    The orange interlock switch would have to be locked, since you disconnected it. Slide the switch downward to lock in place

    The fuel gauge is blinking one dot. If in fact you have more fuel in the tank than indicated by that, this is evidence that the 12V battery is near-dead which caused the fuel gauge system to lose its memory of the actual fuel level.

    If you really allowed the fuel level to get that low, is it possible that you are now out of fuel?

    However, you still should be able to shift into N if you were out of fuel - which reiterates the need to have a well-charged 12V battery installed. One possibility is to use a jumpstart which might help you to make the Prius READY - or at minimum might help you to shift into N so you can get the car out of the way.

    I appreciate the help. I will see if I can jump it. I hope it is the 12v battery. I tried the interlock, no good. The video was taken after I put the battery back in to see if everything would reset. The car has a full tank.

    Resting voltage for the battery was 11.9 volts.

    That shows the battery is discharged.

    I put in a Optima and everything works now. Seems like the 12v battery was the issue. Thanks everyone.
