Mine always worked fine until they completed the recall where they pull part of the dash, I think it was a memory problem. When I read the manual, it stated when at 45mph and over and at dark pull the light stick back (like when flashing the high beams) and hold for 4 seconds and it began to work again. Might look at that if all else does not work. (PS: I got those instructions out the the 600+ page PDF download manual.)I'm used to cars with this feature that turn on when no car is oncoming. I set it but I don't see it turn on. Is there a setting for it? My car says the high beam with the A on but yet to see it.
