works great on my GS. If you set it back to factory settings, make sure the HBC is turned on (under exterior lighting) and read 4-88 in your manual, there is something you are not doing right, or it needs to be checked at your local dealer.A bit late getting back to this problem as I don't drive at night much but unfortunately the button makes no difference. Set settings back to factory settings, have high beam on auto, whichever way I push the button the beams don't change. Have to do it manually.
yes there is very little reason to not leave it on AUTO. I had this feature on my previous vehicle which I owned for 4.5 years and I could probably count on one hand the number of times I switched it to another setting. However, I did not have the HBC featureNo, I'd checked that out earlier. Easy to make that mistake as there are no lights on the stick but auto is the first step up from the bottom so you can do it by feel.
