The driver can’t know the status of the locks without opening the doors and checking them.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the CT4 are reminded to check the back seat if they opened the rear door before starting out. The 2 Series Gran Coupe doesn’t offer a back seat reminder.
