    Posted this in another thread (probably against the rules) but received no response, most likely because the other thread is entitled something completely different.

    Anyway:

    Replaced the hv batt with a brand new one from Toyota.

    Hooked up the 12 volt battery. Put in the big orange plug. Of course, the warning light for "open door" came on. Closed all the doors and the trunk. Put key fob in. Put foot on the brake, and hit the Power button.

    All the warning lights come on as you would expect until the car starts. No start.

    Is there something else I need to do to get it to start after sitting a few days with the 12 volt unhooked, and the HV battery out?

    I see a key reset button under the column. Anything I need to do with that? Key fob locks and unlocks the doors as it should, so I would thing the key fob is being recognized by the car.

    There is a red flashing light on the dash, even with the key removed. It is the shape of a car, but I can't make it out very well, as it only stays lit for a nano second. Is that some kind of anti-theft? It may be an outline of a car with a key inside??? It is right next to a warning light that is shaped like a key.

    One other thing: never saw the "ready" light come on.

    Any help would be appreciated. I would like to get this going today before I take my core back.

    did you slide the orange handle, after snapping it down? there's also a small plug near it that needs to be re inserted.
    is the 12v fully charged? are the connections clean and tight, especially negative to body?

    I am not at home right now, but will double check the orange plug, or maybe just stick a paper clip in there (just kidding).

    Don't remember anything about sliding it down after the handle snaps in place.

    Yes, I did see the other small plugs (believe two maybe three) and they are plugged in well.

    Is there some standard procedure that I am missing that is required to start after both batteries are disconnected for a while?

    Most likely you didn't push/slide down (towards the ground) the orange handle after you pushed it in.

    Yes, you will need to try starting/power cycling it *twice* after disconnecting the 12v.

    If you disconnected the small plug near the 12v, make sure this is reconnected (doubt you would've got this far if it was still disconnected).

    Any DTCs being thrown?

    Assuming there are no logged DTCs, you could try disconnecting the 12v again and see if that resets something.

    Well, you are both correct. Feel like a real dumb a$$. Now that I thing about the orange plug connection, I do remember having to pull up before releasing the handle. Doh!!!! Pushed it down' and all is well.

    Started it a few times, Took it for a drive. No check engine light. No codes.

    The TPMS light is on. Does this car use sensors in the wheels like a Nissan, or use the ABS computer like some GM vehicles?

    I did air up all the tires the other day (before the battery swap). They were all over the place. I already ordered new tires, and will have them put on tomorrrow. Is there a procedure to reset the TPMS?

    Sorry for all the dumb questions, but because we just bought this car, I don't have a shop manual yet. I don't even have an owner's manual.

    Thanks again for your patience and your help.

    Sensors in the wheels, let us know if you find a way to replace the sensor battery- sure seems like a waste to buy new TPMS at $40+ a pop.

    If they have over 32 PSI (or is it 30?) and the light is still on, it means the battery is starting to go out.. they should reset automagically.

    Check pressure. All good. Probably have not driven enough to reset.

    Also

    Sorry, don't know what happened there. Screen just went blank in the middle of posing.
    Probably have not driven far enough to reset the light.
    found this procedure.in another thread.
    How to initialize the tire pressure warning system

    Park the vehicle in safe place and turn the “POWER” switch OFF.
    While the vehicle is moving, initialization is not performed.

    Adjust the tire inflation pressure to the specified cold tire inflation
    pressure level. (→P. 565)
    Make sure to adjust the tire pressure to the specified cold tire inflation pressure level.
    The tire pressure warning system will operate based on this pressure level.
    Turn the “POWER” switch to ON mode.

    Push and hold the tire pressure warning reset switch until the tire
    pressure warning light blinks slowly 3 times.

    Wait for a few minutes with the ON mode, and then turn
    “POWER” switch OFF.

    I will try that Tues. nite. Getting tires put on Tues.

    Put four new Yokohama touring tires on this evening. Took it for a 60 mile trip and all looks good. AC works stellar. Sound system not great, but OK for a commuter. Cruise works great. Steering is way on the light side for my taste, but then the vast majority of miles I have driven since 1982 have been in a Bimmer. Way more road feel and higher effort sterring. But, that is more a matter of personal taste, and not really a complaint.

    Tried filling up with gas before heading out. Gas gauge showed two squares (our of 6 or 8?) which looked like about 1/4 tank. Only took 2.7 gallons. Gat back in the vehicle and it still showed 2 bars. Nor sure if I really got if full, or if it just shut off prematurely. Did a search, and apparently the gas gauge and bladder type fuel cell are common complaints.

    My biggest complaint. Numb butt after only 50 miles. Have to figure out a way to raise the front of the seat. It is like I am fighting to keep from sliding off. Looks like a couple 1/2 inch (scuz me, 13mm for you metric guys) spacers and longer bolts might do it.

    TPMS never went out. Checked air pressure when I got home. Varied from 38 to 48. Nice. Hard to find good help these days, right? Guess I should have checked the pressure before leaving the tire shop. Who knew?

    Anyway, I have no owner's manual or repair manual. So, I haven't a clue what I am looking at on the screen.
    After about 45 miles I had (I think) five yellow bars across the bottom of the display screen. Only had one when I started out. I am guessing that is an indicator that the hv batt is charging. Correct? Or, maybe I am way off base here.

    How long can I expect to drive before the hv batt is fully charged?

    Installed new wiper blades tonight, and may take it to work tomorrow. Next up: changine oil and filter and transaxle fluid.

    As always, thanks for your patience with a hybrid noob, and thanks for any help and advice.

    Register the VIN at http://www.toyota.com/owners and you'll see a link to the owners manual.

    The HV battery is never fully charged. The computer will regulate the state of charge. Generally you'll need to glade down a mountain to see the battery display "full".

    No, that's the fuel consumption screen that is broken into 5 minute increments that constantly refreshes over a 30 minute period. Touch the "energy" icon on that screen to switch to instant mpg's and the battery level indicator that displays purple, blue, and green SOC (state of charge) levels.

    How to disable the center speaker on 05 Prius | PriusChat

    The gas gauge should have 10 pips. When filling the tank you have to put in a over a certain volume (is it 3+ gallons or a percentage of remaining fuel?) for it to reset and register on the gauge.

    Had a couple of pumps kick back/off on me, try the next pump or another gas station if the current pump is acting finicky. Never force gas into the tank or 'top' it off, as bad things could happen.

    Filled it up very slowly and all ten "pips" are showing (or were until we drove 150 miles or so).

    I have to ask, who is the genius that named those bars "pips"? We can't just call them bars? That's what they are on my phone and most other devices that measuer in bars. So, is the speeo unit Gladys Knight?

    BTW, this car performs flawlessly, so not a bad deal. Even with new tires and a new hv batt from Toyota, we have less than $3300 in it.
    Not the most exciting car, but it makes a great commuter.

    Thanks again for all your help.
