I just noticed recently that my auto sense high beams have not been activating like they used to\at all. I know that if you activate the fog lights it will deactivate the auto sense. Saying that, the fogs have been off when i was trying to test.
I have allot of non lit roads around where i am and have not had them come on at all.
There are two green led lights on your mirror, the one on the left is for the auto highbeams, right next to that there is a headlight button on the mirror, push that so the green led is lite, now your auto highbeams will work again.
