    I agree with Bisco....if we have any electrical issue in these hybrids, the first, and easiest, thing to check is the health of the 12-volt battery.
    If you don't have a good battery tester, auto parts stores have them you can borrow (or they'll test it for you.) You don't just want to check the current charge in there, it has a % of health and anything below 70% should be cause to replace it ASAP.

    you'll have to decide between a battery charger and tester, or a new battery. and still, the battery might not be the problem

    Are you positive you had the brake pedal firmly depressed the first time? If you don't, the car goes to ACC and then IG ON instead of READY, and in IG ON, most dash warning lights will be on, which is normal then.
