Replying to: flopshot (Sep 02, 2006 10:47 pm) 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

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. |

Replying to: ocean99999 (Sep 02, 2006 4:03 am) After painfully skimming through the user's manual I found this. 1- On page 10 : "If the hybrid battery becomes fully discharged and the vehicle will not start even with a jump start to the 12 volt battery, contact your Toyota dealership." This is what you did. 2- On page 306 (Jump starting procedure) : "During jump starting, run the engine [of the helping car] at about 2000 rpm ..." DON'T DO THAT FOR THE FIRST 2 MINUTES - This creates a risk to burn the rectifiers of the helping car ! It will also exceed the 5-ampere charging recommendation by a large margin. LEAVE THE HELPING CAR'S ENGINE STOPPED for the first 2 minutes and then you can ramp up slowly to 2000 rpm. 3- Page 307 : "If the first start attempt is not successful... ...Recharge the discharged battery with the jumper cables connected for several minutes and restart the hybrid system in the normal way...." This is what you ended up doing. I always like to know how and why things work (yes, I am an engineer  ). We already knew that the 12 volt battery normally gets its power from the the 244 volt battery. Your mishap confirms that the 12volt-to-244volt converter is bi-directional, and that, when in need, the 244 volt battery can be recharged by the 12 volt battery.
