Why does the owners manual say I have Auto Headlights and Daytime Running Lights?
Because the 2004 Prius sold in Canada does have Auto Headlights and DRLs. But the Prius sold in the US does not. In the US Prius, you can leave your headlights switch in the “on” position all the time, they will be on day and night when driving, and will turn off automatically when you turn off the car and open the door to leave. The manual says to turn them to the off position if you wont be driving for a long period of time.
