There isn't an "Econ" switch on the HAH to override Auto-stop. Just this week, I was stuck in a freeway jam for over 30 minutes at 94 degrees and the A/C performed very well. It is programmed to switch off Auto-stop automatically and from electric compressor back to engine compressor if the A/C can't keep up with demand (this never occured during my recent traffic jam). Also, in a "creep and stop" traffic jam, Auto-stop will only engage 3 times. After the 3rd creep, Auto-stop is disengaged and the A/C switches back to the engine compressor (this did occur during my traffic jam). If you want to re-engage Auto-stop, you just lay back a little until a small gap in traffic forms and then move forward so that the car exceeds 8 to 10 miles per hour. Then you will have 3 more Auto-stops available for "creep and stop" (and probably a honk and rude gesture from the guy behind who thought you temporarily fell asleep, or the guy beside you sees the momentary gap in front of you and tries to take advantage of it). So, it's probably best to let Auto-stop disengage after the 3rd "creep and stop", unless you are intent on saving a little bit of fuel or spewing a little less CO in a freeway "parking lot". If so, then I guess you take your chances with the momentary gap and acceleration to over 8-10 miles per hour.
