Power Door Locks If your vehicle has this feature, you can lock or unlock all doors on your vehicle from the driver's or front passenger's door lock switch. Rear Door Security Locks If your vehicle is a four-door model, it is equipped with rear door security locks that help prevent passengers from opening the rear doors on your vehicle from the inside. Press the lower portion of the switch to lock the doors. Press the upper portion of the switch to unlock the doors. The locking lever on each rear door works only that door's lock. It won't lock (or unlock) all of the doors - that's a safety feature. Using the Rear Door Security Lock 1. Use a key to move the lock all the way up. 2. Close the door. 3. DO the same thing to the other rear door lock. The rear doors on your vehicle cannot be opened from the inside when this feature is in use. 2-9
