Rear-Door Child Security Locks Your vehicle is equipped with rear-door child security locks that help prevent passengers from opening the rear doors of your vehicle from the inside. To use one of these locks: 1. Open one of the rear doors. 2. On the inside of the rear door will be a lock. Insert your door key into this lock and turn it upward. This will engage the safety lock. To disengage the feature, turn the lock downward. Lockout Protection Feature This feature prevents a driver who has left the key in the vehicle's ignition from locking the doors by using the power door locks while any door is open. The feature works by disabling the power door locks when a key is in the ignition and any door is open. You may override the lockout protection feature by holding the power door lock switch in the lock position for more than three seconds while the key is in the ignition and any door is open. Remember, this feature can't guarantee that you'll never be locked out of your vehicle. If you use the manual door lock or if you don't leave the key in the ignition, you could still lock your keys inside your vehicle. Always remember to take your keys with you. Leaving Your Vehicle 3. Close the door. 4. Do the same thing to the other rear door lock. The rear doors of your vehicle cannot be opened from the inside when this feature is in use. If you want to open the rear door when the security lock is on, unlock the door from the inside and then open the door from the outside. If you are leaving the vehicle, take your keys, open your door and set the locks from inside. Then get out and close the door. (Also see "Delayed Locking" in this section for more information.) 2-9
