In contrast to the experience of Ocean99999, I left our TCH in our garage at home for 4 weeks (July 20 to August 17) while on vacation out of the US. I was a bit concerned about the battery situation; since I did nothing special to it other than make sure the Hybrid Synergy Drive system was OFF before before we left home.
 
When I returned, I opened the car door and the interior lights turned on. So I followed the usual starting procedure - put on seat belt, depress Brake, and press the START button. After the usual brief pause, the HSD said Ready and I backed the car out of the garage.
 
I usually leave the headlights in the AUTO position, and note that the headlights remain on for a while after the HSD is shut down.
 
All this leads me to suspect that in Ocean99999's case, the parking attendant probably did not shut down the HSD system, and that triggered his unfortunate experience.
 
If there's any silver lining in his very dark cloud, it's that he could recharge the starting battery and eventually extricate his car.

My guess is the parking attendant simply did not push the Start button to turn off. This is still an unknown elememt in the operation of these vehicles by those not in the know.

While I sympathize with Ocean99999, I'm not sure Toyota did anything wrong here, except not have a knowledgable hybrid person available on their 800 number. Toyota corporate does not handle daily service claims, so they can't authorize a service tech to go into the field. Also, the local dealer in NYC cannot send someone out into the field to service a car, that never happens anywhere, I'm not even sure the dealer that sold the car would be allowed to do that. Getting a tow to a Toyota dealership so that warranty service could be perfomed was definitely the proper course of action, but in this case, a tow was physically not possible. So again, I'm not sure Toyota was to blame for that predicament. But I feel ocean99999's pain, it sucks to be stranded with no one willing to help you, I've been there... with NYC garage attendants at fault!

Thanks to everyone for your comments; I agree that towing to a dealer is the norm when a car "dies".
 
Unable to do this, I did try to jump start the car, following the instructions in the owner's manual prior to calling anyone for service or support.
 
My dissapointment is in two areas:
1) Toyota did not support its customer (me) adequately with this new techniology - if they say thay have a service line, they should have one...a real technical support line - with someone who would have TOLD me the simple solution to my problem (a 30 minute charge)
2) Toyota has no built in device in this car's electrical system to protect against total dischage of the batteries - this technology is available and inexpensive ....and this is a Hybrid, which has a power system COMPLETELY dependent upon having a working battery - in a regular car with a dead battery, its no big deal - a total (or 95% ) discharge.
   
My suggestion: If the car doesn't move for 2-3 hours, the battery cuts out...and when the car is "started" again, it simply requires the owner to push the start button a second time, to reset the system

Actually, the TCH does have protection from draining the battery. I believe the manual says that if the lights are left on (1/2 hr.?) the TCH turns off the lights itself. I just had it happen this morning. My wife left the lights on last night. They were not on this morning and I only noticed as the navigation screen was in night mode and I saw the light switch in the manual on position. But the car started and drove normally.
 
I can't figure how your battery was drained unless the attendant left it in the ACC position. Instead, if it was left in the ON drive position, the motor would have started periodically, as the battery drained down.
 
But the response from Toyota is appalling. At least your dealer tech acted appropriately.

The parking attendant most likely tried to power off the car without putting in in Park. You MUST put the TCH in to Park to shut off the car. If you don't, the dash lights go off, but the system is still on and will kill your battery after a while!!!
 
Perhaps a card to remind folks not familiar with hybrids would help. Shift to Park then Power Off

I refuse to go anywhere that I cannot park and lock my own vehicle. Parking lot attendants are notorious for dinging doors etc. They accept NO responsibility. Valet parking is just asking for trouble.

The TCH is really no different from a regular car when it comes to draining the 12V battery. If you leave something on, the 12V battery goes dead. This is, as already pointed out, nothing to do with the traction battery. The traction battery cannot be depleted as it will disconnect itself when the charge level drops too low allowing the 12V battery to go dead to save itself (bars on the battery display simply show charge available for use as seen fit by the computer, and not the physical charge state of the battery).

Hey droid13 look at Ocean99999's original post #44. Apparently there is more too it than you think.
