I can turn them on and off on my BMW myself, as well as other cars. Lexus and Toyotas can be disabled by the dealer. All others (Honda, Acura, etc) have a fuse that you simply pull out. This is the first car that doesn't have even a fuse. Not a big deal, but DRLs are not a mandated feature, so should be a way to disable them IMO. I like them on my M3, but hate DRLs that use the high-beam bulbs, like this car, that's all. Take care.I have not owned a car nor rented one that had a switch for the DRLs.
