DTR; Canadian cars only?

Owner's Manual discusses Daytime Running Lights in detail.

I'm beginning to think US cars don't have them because they are not federally required; just turn on the headlights during the day, leave them on and they turn off when you open the driver door to get out of the car.

I was really disappointed that the service department was clueless about this rather minor issue.

I have AM-7, thus different headlight technology but this shouldn't make adifference for DTR.

Any inputs on this?
