Yeah, thanks for the link. I had seen that, but later in that thread someone posted a "dealer info" section on what's new in the 2017s and it doesn't mention the Auto High Beams. I don't trust my dealer to know this obscure feature, and they aren't open at night when I could try it on a test...
See, this is what I mean about confusing. You say it's only on hatchbacks in Canada (and provide supporting evidence), then the next guy posts how he turns his on/off in New Jersey.
I googled around for this and found a lot of conflicting information. I'm looking at a 2017 Civic Touring Sedan, and as best I can tell people found that the manual said they have this feature, but other people have reported that their 2016 also said that and didn't have the feature...
