You turn on HAC by pushing on the brake harder than usual.

In my 47+ years of driving I have never had a problem starting off on a hill, but then I have never driven in San Francisco. I think the HAC feature on a vehicle with an automatic tranny is good money spent for nothing. But, for the sake of argument, I tried the system on my 07 RAV anyway. I found that I had to press so hard on the brake to get the "beep" that it felt as though I was going to damage something. I don't recall having to put that much down force on a brake pedal even in a panic stop. I'm sure there are those who use HAC and like it but doubt that I will ever use it in my real time driving.
I'm only venturing a guess, but a sensor/switch sensitivity issue may be in question in both of our vehicles.
