Yes, the 2011 to 2014's have this light sensor on the dash. So as the OP has pointed out, replacing the standard light switch with that of the auto light switch nets you this feature. It also gains you the fog light switch as well (pull out on the switch). So if you plan to add fogs, you need this switch.
As a note, if you buy the Starkey kit, it comes with this OEM switch, wiring harness, fog lights, and bezels.
