If your vehicle has power door locks, press the power door lock switch located on the door panel to lock or unlock all the doors at once.

The power door lock switch will lock or unlock the rear hatch and Dutch doors. See "Hatch Release" in Rear Doors .

When a door is locked, the inside door handle will not open the door. This will help stop a door from being accidentally opened.

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 switch is pressed with a door open, all doors are locked while the driver's side door remains unlocked.
