Auto door unlock feature
 

I own a 2005 PT Cruiser.
When looking through a 2006 model manual i found that there is an Auto door unlock feature there which can be activated using the console computer, which I don't have.
So the question is: Is this feature available in the 2005 model? And if yes how can I activate it, because having to unlock every time to get the kids out of the rear door is anoying.
( I have the Auto door LOCK enabled)
