    CAUTION: Disconnect the power window switch when working inside the driver door. When operated, the Express Up/Down Feature allows the door window to move very quickly, without stopping, which could cause personal injury.
    IMPORTANT: Owners may comment that the windows operate slowly when going up or down.
