Unlike other countries, The US does not require DRLs on every car - probably due to effective lobbying from auto makers who don't want the added expense, but US car makers site a study that suggests DRLs do not reduce accidents and therefore are not needed for safety. I reckon on the non-US models, they made a specific circuit that sends power to the parking lamp when the engine is on. I don't recommend you do that because there is no way of knowing what else had to be re-engineered in the models with DRLs and you don't want to cause electrical or computer trouble on your car. The best thing to do is install your own DRLs that do not use or depend on any existing wiring or programming on the vehicle.
I recommend Phillips Daylight-8 DRLs. They use luxeon LEDs that are super bright and it's a super easy install separate from any other wiring on your car. I had them on my 07 and also have them on my 09. Never any trouble with them.

They come with a wire that can be tapped into the parking lamp that makes the DRLs dim when headlights are on, but I didn't use it. I also didn't use the mounting bracket - I used 20lb test 3M tape from Home Depot. Here is a You Tube install video:

That pic doesn't show how noticeable they are if you are actually driving towards me from the opposite direction.. The camera gets blinded by them if a pic is taken full-on so I had to take it at a slight angle but even at high noon, my car is VERY visible to approaching vehicles. I and others have made DIYs for this and you can do a search under "DRL" to see them. I think my DIY is in the M35/M45 section in the FAQ.
