On the NX, the DRLs switch on when the car is taken out of Park. However, once on, they remain on until the car is switched off.
When indicating, the relevant DRL switches off altogether until the indicators are cancelled. Personally, I think this is a good idea because it makes the indicators more visible.
The facelifted NX has sequential indicators back and front. Bit of a gimmick at the back, given that the indicator lights are rather short!
