Headlight Question for 2011 Prius Two - US Version

Considering purchasing a 2011 Prius Two - US Version and have a very basic question regarding the headlights.....do the headlight automatically shutoff if left on by mistake? If not, is there any chime telling you the headlights are still on? The salesman first indicated yes to both questions but when we tried it the lights remained on and there was no chime to indicate the lights were still on. The salesman also indicated it may be due to the fact the car had not been prepped. The manual seems to indicate yes to the automatic shut off but that may be only on the Canadian version with the daytime running lights. Any insight would be appreciated.
