The setting you adjusted is the delay for auto re-lock. Should you inadvertently unlock your car, if a door isn't opened in 30seconds, it will auto lock the car.

 

Unlock the car ----> do not open any door ----> 30 sec ---> doors closed.

 

I'm pretty sure i waited more than 30 seconds and the doors never locked :wtf:

 

With fob in hand lock car and walk away from the car for a bit. So proximity sensors no longer see the fob. Then from a bit of distance press the unlock button. Wait 30sec and don't touch any doors. The car should lock itself again.

 

how do you keep the doors from unlocking when putting the car in park?

 

Setup (see pic) >Vehicle

You can disable the auto lock into park from there.
