    I don't have a tire pressure RESET switch in the position under the steering wheel as depicted in the manual. Am I just blind?

    I had a hard time finding it myself the first time. Get a flashlight and look under the dash by the steering column.

    I had the same problem...the manual makes it look like it's up higher. At least I know where the OBDII connector is now!

    Re: Can't finf tire pressure RESET switch

    I could have used this thread yesterday.:) I looked and then got the book out and looked more, still could not find it. I started to come here and also ask the question, but decided to look one more time and found it.

    On my 2007 it was easy to find, but anyway now I know.:rockon:

    I think the reason for it being so low is the driver's knee airbag.

    Re: Can't finf tire pressure RESET switch

    Am I correct to assume that after I increase my tires' psi, I should press the reset switch? Or , do I press the switch only if tire pressure light comes on after I increase psi to 42/40 level? This is the first car I have owned that came with a pressure reset switch.

    Re: Can't finf tire pressure RESET switch

    The TPM is set for a 8 psi diff. from factory plate settings.
    If you run your tires at a higher pressure then those on door plate then it is a good idea to reset it so it knows there is a new pressure and it will still alarm on the 8 psi diff.
    It's more then just pushing the reset button. There is a post on the forum someplace on how to do it. It might even be in the manual but i haven't looked and it's out in the car right now. Might try afew serches on forum to see if you can find it...it has to do with the TPM light on the dash blinking.
    Hope this helps

    I hope i got all this right.
    If not someone will jump in.

    Yes. Press and hold while the symbol on the dash blinks and goes out.

    So I have looked for so long and I still can't find this button. ALL I see under the steering wheel is a button that says key. My email is [email protected] if someone wants to take a picture, or else just give me some landmarks like the obdII etc. Thanks.

    It is located right next to the "key" button. Did your 2005 Prius come with TPMS?

    TPMS was first installed in 2006. The 2004/2005 do not have it.

    Alright thanks for clearing that up. I bought my car from a Ford dealership a few weeks ago and I asked about the ((!)) symbol on the dash. He said it was from the tire pressure monitoring system so I just took his word for it. I am guessing it is probably something relating to the brakes?

    Re: Can't finf tire pressure RESET switch

    8 psi under desired pressure is pretty gross. It would make sense to add an extra 4 psi before setting it, then bleed off the 4 psi to your desired pressure so it goes off at 4 psi below your desired pressure. Or maybe closer than 4 psi.

    Haven't got it handy, but the Owners Manual says something to the effect of letting the car sit in Ready mode (on) for "a few minutes", after doing the reset. Anyone know anything more definitive on that time interval?
