Delayed Locking When locking the doors with the power lock switch or the keyless entry transmitter and a door or the liftgate 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 turn the delayed locking feature off or back on again by doing the following: 1. Press and hold the power door lock switch in the lock position. 2. Press unlock twice on the remote keyless entry transmitter. This feature will not operate if the key is in the ignition. You can also program this feature using the Driver Information Center (DIC). See "Door Lock Delay" under DIC Vehicle Customization on page 3-67. Programmable Automatic Door Locks Your vehicle is equipped with an automatic lock/unlock feature which enables you to program your vehicle's power door locks. You can program this feature through the Driver Information Center (DIC), or by the following method. Programmable Locking Feature Following are the two available programming options: Mode 1: All doors lock when the transmission is shifted into gear. Mode 2: All doors lock when the vehicle speed is greater than 8 mph (13 km/h). The automatic door locks were pre-programmed at the factory to lock all the doors when the transmission is shifted into gear. The following instructions detail how to program your door locks differently than the factory setting. Choose one of the two programming options listed above before entering the program mode. 2-10
