Power Door Locks Press the bottom side of the power door lock switch to lock all the doors at once. Press the top side of the power door lock switch to unlock all the doors at once. Rear Door Security Locks Security locks are located on the passenger side rear door, the side sliding door or the front portion of the 60/40 side swing-out door. With this feature, you can lock these doors so they can't be opened from the inside by passengers. When a door is locked, the inside door handle will not work. Rear Cargo Door Move the lever down to engage the security feature. Move the lever up to return the door locks to normal operation. Cargo Door Relocking This feature protects the owner from having an unsecured side cargo door. If the side cargo door is open when the lock button is pressed on the door or the remote keyless entry transmitter, all doors will lock and then relock again after the cargo door is closed. If the cargo door is not closed within several minutes, the relock will not occur. 2-8
