How does the small lamp under the headlight in front of Camry make it light up? Why can't I get on?

Hello, the two small lights under Camry headlights are front fog lights. The premise of turning on the front fog lights is to turn on the width indicator or headlights. Camry's headlight group switch is on the steering rod on the left side of the steering wheel, and the outermost switch is the headlight group switch. The current position is closed. The width and atmosphere lights in the car are in the high-end position, and the low beam lights are in the high-end position. The top fitting is in automatic mode, and the fog lamp can't be turned on in automatic mode. A minimum width indicator is required to turn on the front fog lamp. Or low beam mode, and then the inner ring switch, now the position is off, the first gear is to turn on the fog lights under the headlights, and then turn on the rear fog lights.
