Did my 12-volt drain or is it worse?

Hey guys, I am in emergency mode here.

I left _something_ on the car running for 20 hours. Trying to determine, after the fact, what I did:

Option 1) Something that just drained the 12-volt (left the window wipers going is the biggest culprit)
Option 2) the car engine running in "ready"
Option3) the car engine in full-on drive mode.


The story is, I am at a music workshop/boot camp/party about 300 miles from home. I parked the car around 8:00-8:30 yesterday morning, got out all of my gear, closed the door, and forgot about it. I have about three quarters of a tank of gas (or I did when I parked).

I returned to the car at 3:30 in the morning. When I tried to start the car, I noticed a lot of flashing lots on the dash. (I do not remember what they were, because I was totally exhausted and not in an analytical frame of mind.) The EV system did not turn on. If I recall correctly, the window wipers _may_ have been running, but very slowly.

At 3:30 AM, the dome light _was_ working, but it was not bright enough to read the owner's manual.

I came back to the car just now, about 8:30 AM (24 hours after I last drove it). The key-detect system does not seem to be working. More or less anything that would depend on the 12-vote does not work. When I try to start the car normally (foot down, press the button), nothing much happens except for an emergency light.


Big Question:
Is it safe to try to jump the car? And if so, do I need to leave it "on" to recharge the hybrid system battery?
(or) Do I need to take it to a dealer and get the hybrid system recharged?

Any insights appreciated!!
