Automatic Door Locks
WARNING: This page is about a different car, the 2016 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
When enabled, this feature will lock all of the door locks if all of the doors are closed and the vehicle speed goes above 25.7 km/h (15 mph). If a door unlock has occurred, then the BCM will perform another auto lock, if the doors did not electrically unlock, another auto lock will not occur.
