Automatic Door Lock On vehicles with power door locks, the doors automatically lock when the shift lever is moved out of (P) Park for a vehicle with an automatic transmission. For a vehicle with a manual transmission, the speed must be greater than 5 mph (8 km/h). The automatic door locking feature cannot be disabled. Rear Door Security Locks Vehicles with rear door security locks prevent passengers from opening the rear doors from the inside. On vehicles with this feature, the rear door security locks are located on the inside edge of each rear door. You must open the rear doors to access them. Programmable Automatic Door Unlock Your vehicle will automatically unlock all doors when the shift lever is moved into (P) Park for a vehicle with an automatic transmission, and when the ignition is turned off for a vehicle with a manual transmission. If your vehicle has a Driver Information Center (DIC), the doors can be programmed to automatically unlock several ways for vehicles with an automatic transmission. See DIC Vehicle Personalization on page 4‑54 for more information. To set the security locks, do the following: 1. Insert the key into the lock below the rear door security lock label and turn it to the horizontal position. 2. Close the door. 3. Repeat the steps for the other rear door. 3-11
