I just checked. The headlights come on while driving in any of the 4 possible settings on the stalk.
Whats the point in having these cool looking DRL shapes when all you can see are headlights? Why not stick stock halogens / LED headlights and reduce MSRP by $50. What sucks for 17s is that iJDM Toy or others will probably not be making any aftermarket DRLs since all models get this fake DRL. Atleast we 16 owners can get aftermarket near the fog light housing.
I am guessing number of 17 owners who are pissed are > 50%. We need to put this as a sticky for potential 17 owners.
So it looks like Mazda USA has decided to have lights on all the time regardless of what setting you select on the stalk. Therefore having DRL's on the GT is pointless.
I suggest all those who have bought the GT do to Mazda and ask for a refund for the proportion of the DRL cost added to the GT!
