will unlock every time the vehicle is stopped and the

or power door lock switch. When the door is closed
again, it will not lock automatically. Use the manual lock
knob or power door lock switch to lock the door.
The door locks can be programmed through prompts
displayed on the Driver Information Center (DIC). These
prompts allow the driver to choose various lock and
unlock settings. For programming information, see
DIC Vehicle Customization on page 4-80.

opening the rear doors from the inside.
