2007 dead battery

You're supposed to jump start it from the front engine compartment, not the rear. See pages 360-363 of your manual.

I would call a local Toyota dealer and let them know your tried jump starting from the rear.

That's strange about AAA. Did they say why they wouldn't help? I have AAA, too, and wouldn't want to be unpleasantly surprised someday if I need their help.

 

If the 12v battery is original, there is a good chance it could have died from the discharge. Getting a voltage reading from it would help trouble shoot. I personally would pull it and put it on a charger as my next step.

 

If the original battery has shorted, it will prevent you from doing a successful jump start. Disconnect the original battery and try jumping without it. If that works, you need to replace the battery.

could anyone edit the title into 12volt.. because this post will add up to the prius dead ( hybrid )battery hoaxes

 

1. I hope that you know the difference between red and black, and positive and negative while jumpstarting the Prius. (The positive cable from the jumpstart device goes to the red terminal or positive side of the Prius battery. The negative cable from the jumpstart device goes to unpainted metal connected to body ground.) If not, then damage may have been caused to the electrical system including the inverter.

2. If you are confident that you correctly connected the jumpstart device, did you fully depress the brake pedal while trying to start the car? If yes and the car doesn't start:

3. If you have access to a battery charger and metric tools, then disconnect the 12V battery negative cable where it attaches to the car body, and hook up the charger to charge the battery. The point of disconnecting the negative cable is to clear the check engine light.

4. After charging for several hours (or once the charger shows it is done) remove the charger and reconnect the 12V battery negative cable to the body, tightening the bolt securely.

5. Press hard on the brake pedal and see if you can start the car.

6. If the car doesn't start, you can either install a new 12V battery (which is not the easiest thing in the world to do; look for posts on that subject) or else have the car towed to your local dealer for help. Good luck.

 

If you actually did not shut the car OFF last night and it ran out of gas then the hybrid battery may be dead. That would require a tow to a Toyota dealer to recharge the high-voltage traction battery.

As Patrick implies, if you're not certain of what you are doing, call Toyota. As with any modern car an incorrect jump can do hundreds or even thousands in damage.

 

I don't believe this is possible with Gen II.

The car should fire right up with a simple jump-pack. I'm a bit worried that Suzanne's initial attempt was reverse polarity

 

On the off chance that computers are confused, try disconnecting the negative from the battery for 5 minutes, then reconnect and try to start it.

 

A backward jump on a Prius can cost a few thousand dollars. Hopefully that's not an issue.
