Power Door Locks A power door lock switch is located on both front doors next to the door handle. Delayed Locking This feature allows the driver to delay the actual locking of the doors. When the driver power door lock switch is pressed with the key removed from the ignition, and the driver door open, a chime will sound three times to signal that the delayed locking system is active. When all doors have been closed, the doors will lock automatically after several seconds. If any door is opened before this, the timer will reset itself once all the doors have been closed again. Pressing the driver or passenger power door lock switch again or the RKE transmitter button will override this feature. Personal Choice Programming Press the top of the switch to unlock all doors or press the bottom of the switch to lock all doors. If the vehicle has the optional content theft-deterrent system and it is armed, the power door lock switches will be disabled. You must use the RKE transmitter or the key to unlock the doors when the system is armed. See Content Theft-Deterrent on page 2-16. The delayed locking feature can be turned on or off, using the Driver Information Center (DIC) to program this feature. See "DELAY DOOR LOCK" under DIC Vehicle Customization on page 3-57. Automatic Door Lock The doors will automatically lock when the shift lever is moved out of P (Park). The automatic door locking feature cannot be disabled. 2-10
