    Help! I have a 2007 Prius. We left for vacation for 2 weeks. Came home
    Started the car and then all the lights came home. I thought the battery must have drained. But the lights are all on with a new battery. Is there a way to clear all these?
    Any suggestions?
    Thanks

    You need to clarify "all the lights" and did the vehicle go into ready mode...would it drive?

    The red triangle , the tire pressure light, the vsc the check engine
    Then on the navigation screen the car with the exclamation point. The screen has been acting weird and not responding. To where I touch

    welcome! sounds like your hybrid battery went south too. how many miles on her? btw, the old 12v may be fine. but if it's original, don't bother with it.

    Take it to the dealer or a specialist that works on Prius or hybrids only.

    For it to go 40 miles, I have a couple of questions. Does the A/C work normally? Does cruise control work? Can your car go above 70 mph?

    The answer to these questions will tell me if your car went into "limp in mode" or Limited Operation Strategy. Please let us know.

    The a/c hasn't been very cool for awhile
    I don't know about cruise or above 70. I think I drove around 60 to 65

    Hmm, kind of ironic. A/C hasn't worked right in a while. Do you get out on an Interstate? Because if you cant go above 70 and the cruise doesn't work then the Prius will actually protect itself.

    I worry that you may be stressing out components, like the inverter.

    sounds like the main battery, go to an auto parts store and have then scan for error codes, write them down and look them up on line..
