2 things I discovered this morning.

1. It will not allow you to reverse the car when your driver side door is
open. I was trying to see if my rear wheels will hit the kerb by opening
the door to look. Engage "R" gear and when I open the door, it
automatically switch back to "P".

2. It warns you if you are adjusting your rear seats when in motion.
Wife tried to bring down one side of the rear seat to get access to
the rear compartment. Warning lights and sounds came on instantly.

Guess the above features are for safety reasons.
