The reason the headlight auto-off acts the way it does is because you may actually want or need light with the car powered off. Also the only way the car can guess the driver is leaving is if he opens his door. If he didn't open his door, he is most likely still inside and still needs the headlight.
You wouldn't want to have to change a tire at night and find that you can't even turn on your taillights with the system off. You might not be seen at the edge of the road and get hit.
Thanks, Dan, for clearing that up. I hope my drained battery has recharged enough not to have caused a problem.

Don't put off till tomorrow what you can do today.

Is turning off the lights for you fewer steps than closing the driver's side door is for the rest of us? Easier steps to remember? Not sure I see the advantage of doing it that way -- just seems like the old-fashioned and harder way.
Is getting a jump less annoying for you than for the rest of us? :_>

Never had to get one -- the way I turn off the lights is 100% as effective as the other way, of course -- but I expect it'd be the same if I did have to.

If you're interested in getting the point, the point is, there are two ways to ensure the headlights are off in the Prius. One is marginally harder than the other. If someone wants to advocate the harder one, they should present an advantage it has; presumably, that it's easier for them to remember to do, for some reason, and ideally what the reason is.

Of course, if you'd rather just be surly, that's fine, have fun.

I usually turn off my headlights, but sometimes I forget. Fortunately the pattern that would have me leave them on also allows for the Auto-Off to take effect.

I think being easier is more important than being fewer steps. It would be fewer steps for me to leave the window open and climb in rather than incurring the extra step of opening the door and the extra step of closing the door. I do think it is easier to just turn the lights off. Then I don't have to "remember" to turn them off when I drive the car the next time. Leaving them on is not the same as daytime running lights. In the Prius, the tail lights come on when the headlights are in the on position, which I really don't want to happen. When I get where I'm going at night, I can clearly see that my lights are on and turn them off. It is a single habit that can be formed that does exactly what I want and I never need to think about. Like I said, if the feature was a true "Auto" feature with a light sensor, I would agree with you, but it isn't, at least in the US version.

The auto-off feature that Toyota included with the Prius is not anything like an auto lamp feature that you seen on other vehicle.

Prius auto-off is a stop gap feature to help protect the 12v battery. It was designed to kill the headlights after the car is powered down and the drivers door is opened. However a true autolamp system will turn off the headlights after a time delay from when the vehicle was turned off. Also, true auto lamp will turn on the headlights when it gets dark out and turn them off when it is sufficiently light out.

I do not suggest anyone rely on the auto-off feature of the Prius due mostly to the need for a specific order of events to occur for this feature to work.

A simple solutioN to door ajar dome lamp on situations is to look at the dash at the are of the door ajar light when you exit the vehicle. If that light is off, your dome lamps will also turn off after their prescribed on time has elapsed.

It has been said:
Hybrid drivers come in 3 flavors, greenie, techie and cheapie. Pick any 2.

Ah, there's the answer. Hadn't occurred to me there are still people doing that. So we'll see from Hep's survey how wrong I am about that.

But that order (closing the driver's side door after the car is turned off) is no more dependent or difficult than the order required for the "turning it off manually" feature to work.

Why would you leave the headlights (and taillights) on in the daytime? Most "Auto" headlight features, even those with DRL don't do that with the taillights.
