I am trying to figure out how to set the DCA to stay on rather than having to push the button everytime I start the car? I held the push button in for 10 seconds and that didnt work. I checked the forum but dont seem to be able to find an answer? When I have the DCA active it actually brings the vehicle to a complete stop when approaching a car (or other object like my garage door) which I like. I actually havre never used it in the last 3 1/2 years of owning the car but when I decided to just try it the other day I realized it is a great function.
