Power Door Locks (If Equipped) If your vehicle has power door locks, press the power door lock switch to lock or unlock all the doors at once. Every vehicle with power door locks has a pulse lock system. A pulse lock system works like this: If the sliding door is open and you press the power door lock switch, the sliding door will not lock immediately. After you close the door, the system comes on and locks the sliding door in about five seconds. When the key is in the ignition and the power door lock button is pressed with a door open, all doors are locked while the driver's side door is unlocked. All models have overriding door locks. When a door is locked, the inside door handle will not work the latch. This will help stop a door from being accidentally opened. The power door lock switch will lock or unlock the rear hatch and Dutch doors. See "Hatch Release" in the Index. Leaving Your Vehicle 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. 2-7
