Ok, can someone confirm... I don't have that Auto hill hold assist option, BUT, I'm convinced if you are pointing down a hill and put it in reverse, it DOES hold for a second and won't roll forward. Likewise, if you are facing up a hill, in first gear, it holds for a second and won't roll back. It does this without manually having to touch the Parking (hand) brake.
Can anyone confirm...?
Also, if you have have the parking brake on and try and reverse back, it won't let you as you need to release the parking brake manually. So it only auto releases when you drive forward, is that right?
Hope this all makes sense!
