Found this out while I was sitting at the drive though, long idle.
1. Place the hand brake on.
2. Move gear selector to Neutral.
3. Press Start/Off button
Enjoy the car going into accessory mode and not fully shutting down
Ok now the drive though line starts to move.
4. Depress brake peddle.
5. Push Start, car turns on.
6. Disengage hand brake.
Now I'm on my way to get my grub on.
This might seem dumb to our fellow key owners but the smart key suck at just trying to get to accessory mode from a running mode.
