Personal Choice Programming 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 231. Rear Door Security Locks Your vehicle has rear door security locks, that prevent passengers from opening the rear doors from the inside. The rear door security locks are located on the inside edge of each rear door. You must open the rear doors to access them. To assist you in finding the lock, your vehicle will have one of the following: Programmable Automatic Door Locks Your vehicle is programmed so that, when the doors are closed, the ignition is on, and the shift lever is moved out of PARK (P), all the doors will lock. The doors will unlock every time you stop the vehicle and move the shift lever into PARK (P). If someone needs to get out while your vehicle is not in PARK (P), have the person use the manual lock knob 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. If your vehicle has a Driver Information Center (DIC), you can choose various lock and unlock settings.
