Programmable Automatic Door Locks Your vehicle has an automatic lock/unlock feature which enables you to program the vehicle's power door locks. You can program this feature through the Driver Information Center (DIC). See DIC Vehicle Customization (With DIC Buttons) on page 264 for more information on DIC programming. Delayed Locking When locking the doors with the power lock switch or the remote keyless entry (RKE) transmitter and a door or the liftgate is open, the doors will lock 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 RKE transmitter twice will override the delayed locking feature and immediately lock all the doors. 121
