2-6 Keys, Doors and Windows Automatic Door Locks If the vehicle has power door locks and the remote keyless entry system, it has an automatic lock/unlock feature. If the vehicle has an automatic transmission, it is programmed from the factory to lock all doors automatically when the shift lever is moved out of P (Park). All the doors will unlock when the shift lever is moved back into P (Park). If the vehicle has a manual transmission, it is programmed from the factory to lock all the doors when the vehicle speed is greater than 24 km/h (15 mph). The doors will unlock when the key is removed from the ignition. To change the automatic door lock and unlock settings, see "Automatic Door Locks" under Driver Information Center (DIC) on page 5‑19. Lockout Protection If the vehicle has power door locks, this feature protects you from locking the key in the vehicle when the key is in the ignition and a door is open. If the power door lock switch is pressed when a door is open and the key is in the ignition, all of the doors will lock and then the driver door will unlock. Safety Locks (Crew Cab) If the vehicle is a crew cab model, it may have rear door security locks. With this feature, the rear doors are locked so they cannot be opened from the inside. The rear door security lock is located on the inside edge of each rear door below the security lock label. To engage the security locks: 1. Open one of the rear doors. 2. Using the ignition key, turn the lock to the horizontal position. 3. Close the door. 4. Repeat these steps on the other rear door.
