[Tess]

This position of the rotary switch controls the fog lights. Here is some information about fog lights: 1. Purpose: Fog lights, installed at the front and rear of the vehicle, are used for road illumination and safety warnings during driving in rainy or foggy weather. 2. Classification: Fog lights are divided into front fog lights and rear fog lights. Front fog lights are generally yellow, while rear fog lights are red. The symbol for the rear fog light is slightly different from that of the front fog light—the light lines of the front fog light symbol point downward, whereas those of the rear fog light are parallel. These symbols are usually located on the instrument control panel inside the vehicle. In foggy weather, both front and rear fog lights are typically used together.
