When locking the doors with the power lock switch or the keyless entry transmitter and a door or the liftgate (if equipped) is open, the delayed locking feature will delay locking the doors until five seconds after the last door is closed. You will hear three chimes to signal that the delayed locking feature is in use.
Pressing the power lock switch or the lock button on the keyless entry transmitter twice will override the delayed locking feature and immediately lock all the doors.
You can also program this feature using the DIC. See DIC Vehicle Customization .
