It cannot be adjusted. Tell me where in the manual it says anything about adjusting. I'm not going to waste my time at a dealership for a problem I can remedy by manually operating the brights.
The auto on/off works perfectly for me. On two cars. But they do need to be mechanically calibrated. That is different than a software-based sensitivity adjustment you are implying, which does not exist. You can certainly go on using the manual adjustment if you want, but O'Donnell Honda calibrated mine properly. On two cars.As stated above, the manual does not state anything about adjusting the high beams. The auto on/off sucks. It never detects oncoming cars. Manual on/off is much better.
