    There were a few posts indicating that hitting the Park button by accident while moving above a certain speed will not cause any catastrophic damage to the transmission. When I first got my Prius, there was one time when I was pulling into a parking lot and had hit the Park button before I had come to a complete stop as I was not yet used to the entire "parking-power off" sequence, and the car jerked to a sudden stop. I've also found the location of the Park button not the most ideal as it is near the HVAC buttons and can easily be pressed by accident or while I'm resting my wrist on that area while adjusting the vent settings.

    To prevent this from happening again and possibly damaging the car, I installed a cover over the Park button. I glued a small hinge to the edge of the center pod by the shifter and then glued a piece of Lexan to it. Now I never have to worry about hitting the Park button prematurely or by accident(even if people say that hitting the button while the car is still moving will just trigger an error message on the display, I really don't want to experiment on my car). The Lexan allows me to still see the lighted button clearly at night.

    Software lockout already protects your Prius against damage from shifting to Park at too high a speed.

    Clever, but keep in mind that pressing the Park button during an Unintended Acceleration Incident is the probably the fastest way to decouple the power to the wheels.

    I can't find the Park button fast enough for that, but can shove the shifter into R (which really goes N) just as fast as I hit the clutch when my old Honda when UA.

    And just in case evpv doesn't remember, I do have first-hand experience with UA in a Honda.

    Summit123, I hate to ask the obvious; is it always your habit to start to reach for the Park button BEFORE you stop? Did you do this in your previous vehicle where you start moving the shift level into Park BEFORE you stop? If so - cut that out! DUH!!! Since you know you'll try it again, I credit your ingenuity for the solution you created that allows you to maintain your habit while not causing any damage.:confused::p

    I have a friend who I observed frequently does that - throws the column mounted shifter up from Drive into Park just before coming to a complete stop (Chysler minivan). Imagine his surprise when the transmission went out at a cost of $4,000. Hmmm, I wonder what problem could be......:rolleyes:

    Like I was saying, this incident happened shortly after I had just bought the car and wasn't entirely used to the 2-button park sequence. I don't know why Toyota didn't just completely deactivate the Park button at ANY speed above zero to help minimize the possibility of transmission damage. It should be a very simple software edit.

    Even if hitting the button accidentally only decouples the wheels from the engine, I would rather not have to deal with this sudden loss of speed especially when I am on the highway.

    The park button seems overly redundant. They should have built the park feature right into the shifter. All it ends up doing is adding one extra button to the clutter.

    It was a design decision. It would be easy to require zero speed before activating park, but if Toyota did that we would have people starting threads saying: "I tried to shift into Park to keep my Prius from rolling away, but it wouldn't let me shift. Why did Toyota design it this way?" Toyota limits Park to safe speeds: You can't hurt your Prius shifting to Park while moving.

    A fair point, but no different than shifting to N by bumping the shifter. Given the recent rash of SUA complaints, perhaps we should consider this a feature, not a problem.

    They could of. It's another design decision, but in this case I don't know the reasoning behind the decision.

    I had the opposite problem, at night I had a tendency to press the Auto HVAC Button instead of the Park Button because the Park Button is not illuminated and I couldn't see it. Just pressing the Power Button after setting the parking brake fixed that problem.

    I accidentally turned on PWR mode in my car one day while meaning to hit the rear defogger button. Didn't look to confirm that I hit the right thing, and when I shifted to park and pushed the gas pedal, the car shot away from the spot I was at.

    I think Toyota should put a fix in for my ignorance on this. It really is a big design flaw :rolleyes: - Heck, even Microsoft makes me confirm that I want to shut down my computer after deliberately making 2 or 3 clicks in different spots.

    Yes, that is a bit of sarcasm, but that actually did happen. When you're expecting to be in "normal" mode and you're in "power" mode, it really does make a difference in the half second after you press the pedal.

    Like you, I understand that hitting the Park button while moving
    won't hurt my Prius but I don't want to test this myself!

    Your makeshift safety cover reminds me of the one the late
    astronaut Jack Swigert made for Apollo 13. Swigert was in
    the Apollo Command Module powering it up, while Jim Lovell
    and Fred Haise remained in the Lunar Modular. Swigert had
    to flip a lot of switches in a complicated order, and being
    groggy from hardly sleeping in two days, he was worried he
    might accidentally flip the switch that cut loose the Lunar
    Modular while Lovell and Haise were still in it. So, Swigert
    taped a piece of cardboard over that switch and wrote, in
    big letters, "NO" on it.

    I was thinking of exactly the same thing, LOL.

    My 2 cents:

    I never push the park button, just power off, and rely on the car's function which automatically then puts it in park. I can't think of an instance when I'd want to leave the car running and in park.

    If you're concerned about this, and could live with just haveing auto-park, it might be possible to disconnect a the wire to this button at the back, without triggering a fault, or messing up the car's auto-park function.

    As several responders have mentioned, the car's software will prevent shift into park at higher speeds. You might be able to put it into park at a crawl, and experience a bump, but I believe that's it.

    Any chance you can get that glue to come off? Honestly: at trade-in time I don't think any prospective buyer will be interested in this feature.

    it was just a dab of silicone. I should be able to remove it easily with a thin blade.

    I can conceive of a few instances when you might want to put the car in park, rather than shut it off. There is one that I use every day.

    Frex, a neighbor might be passing by, walking the dog, and you want to stop to exchange a few words.

    Or it's night, you just started the car, and you want to run back into the house and make sure you turned off the oven, but you don't want the timer to shut off the headlights.

    I do it when I pull up to my mailbox to grab the day's mail. It's an awkward reach, and I cant simply keep my foot on the brake and get the thing that's stuck at the back of the mailbox. But I don't want to shut down, and make somebody who needs to get by me wait while the car goes through its start-up sequence.

    And, of course we've all been in the situation where our friend has been holding up a bank, we're driving the get-away Prius, and he comes out in a hail of bullets.

    Like the OP, I've pressed Park before coming to a complete stop too, when I meant to turn off the radio. It's just stupid on my part, but it can happen and yes it sucks. :D

    I always thought it was a good thing that he didn't tape it on upside down!

    maybe you can glue on a similar cover on the other side of the center pod since the Power mode button is all the way on the right of the 3-button mode selection. Or better yet, just add a cover on every single button in the car so we will never hit the wrong button again!
