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. For programming information, see DIC Vehicle Customization on page 3-65. Rear Door Security Locks Your vehicle has rear door security locks. These 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 set the locks, do the following: 1. Insert the key into the security lock slot and turn it so the slot is in the horizontal position. 2. Close the door. 2-13
