The cvt transmission will disengage if left in drive and vehicle is shutoff. you can turn off vehicle while it is in drive and the vehicle will roll back and forth, as if it was in neutral. forgot to put vehicle in park, pressed the push to start and vehicle shut off. 3 short beeps is the only warning, exited the vehicle and it rolled backward out the garage and into yard across the street. this is a new vehicle and not use to push to start function.
