2013 Lincoln MKZ 2.0 Ecoboost. I have the THX sound, 19" wheels and panoramic roof. I'm not sure what package # that is. Not a fleet vehicle.
I just got my lower LED's activated, it took 3 tries in total. I tried twice with the Astro Lincoln in Pensacola Florida but they said it couldn't be done. The first time I told the service guy (who was very professional btw) that I wanted the DRL's activated and pointed to the lower LED's. He said the service tech couldn't find it in the computer and it wasn't an option for my model. The next time I told him to tell the service rep to check the Daytime Driving Safety menu but once again he said the service tech could not find the option to enable.
I relocated a couple of weeks ago to Marietta GA and I had to take my car in for a gas smell (it turned out to be a leaking fuel pump). I asked the service manager at Pugmire Lincoln of Marietta to activate the lower LEDs and told him it should be in the Daytime Driving Safety menu. Sure enough they did it. Apparently they already knew how to do it, because he said they normally charge $60 to activate the DRLs.
The lower LED's (signature LED) are on only in drive and are on even if the headlight knob is turned to the off position (circle).
So to summarize, 2013 MKZ lower LED's can definitely be enabled even if your car is NOT a hybrid. But it all comes down to how knowledgeable the service tech is. Here's a pic of my car and the service receipt. As you can see the parking lights are not on but the lower LED's are.
