best thing I ever did was get it programmed to last setting, (ie off).
It is rough system, very noticeable on and off, and absolutely dangerous in lag trying to pull into traffic.
Also, it is amazing that their is not a safety override feature, if the engine shuts off via ASS, and you put the car in park, and open the door, the engine restarts.
Thus it is possible to exit the car, lock it and leave the engine on.
Happened to a family member who is deaf, drove in to a parking lot, stopped, checked something on cell, forgot that car turned off, came back to a running engine.
