Check Hybrid System

Where are you located?

 

Sounds like your 12v battery in the hatch is low and needs to be replaced.

Lots of unrelated warning lights and errors is a common symptom.

 

Like xl said, it sounds like your 12 volt battery is low. I would check that first before having it towed. It would help if you were to add your location to your personal info so it will show up in your avatar.

 

Voltage at the battery terminals can be measured with a $5 multimeter (Walmart, etc.).

Sounds like your problem is that the car sits around for long periods and the 12 volt auxiliary battery discharges. Do it frequently, and even a relatively new battery will fail.

 

you can measure it at the jump point under the hood, instead of crawling in the back and unlocking the hatch manually. of course, if it's dead, you'll have to crawl in the back.

 

Have you checked your oil level?

 

is it out of gas??

 

Out of gas while showing one bar of gas left caused mine to stall and not start one time

 

Let us know what the outcome of the 12v batt chk is.

 

The battery has smaller than normal posts, and it's dimensions too are quite compact. Also, since the battery's techinically in the passenger compartment, it should be AGM type and have the proper vent connection. Simplest route would be likely a dealership. If you have the time, this battery will also do:

Optima Battery 8171-767 (DS46B24R)

(it's available on Amazon, for example)

So, "walmart" equals you're in North America??

 

it's a little harder than a regular one under the hood. learn how to test it properly, then cross that bridge if you come to it.

 

add 4 gallons of gas, put a charger on the 12 volt battery and hope for the best...
I never go below 3 bars on the gas gauge or 350 miles between fill ups
if you have been playing with the car you have run the battery down so it will need to be charged either way.
if you ran the traction battery down below 10% you will have to get it towed to the dealer for a recharge
been there done that cost me almost 250 bucks for running it out of gas and limping it off the highway on the battery

 

Just noticed this. So what battery is in there now, where did you get it changed, dealership? Original battery is always Yuasa I think.

You really should pick up a digital multimeter, and inexpensive one can be had for around $20. Read up a bit, check your battery's voltage when the car's off. If you check it within a day of driving and it's 12.5 volt or higher you're fine. But yeah, measure it and post the result.

 

^ ^ ^ What he said. Use a digital volt meter. Check the voltage at the jump post under the hood. Report back with the readings. Ideally you need to check the voltage after the Prius has set overnight and BEFORE it is started up (put in ready mode).

The voltage when it is in "Ready" mode is NOT needed. Just the voltage of the battery while the Prius is OFF.

I too would like to know about the replacement battery mentioned. Is it OEM or aftermarket? What brand, part number, rating, etc. ?
