There is a fog light button marked near the instrument panel. After turning on the lights, press the front fog light button to illuminate the front fog lights. Press the rear fog light button to illuminate the rear fog lights. When you turn the button marked with the fog light symbol in the middle to the ON position, the front fog lights will be activated. Turning the button downward to the rear fog light position will simultaneously turn on both the front and rear fog lights.

Operating the fog lights on models is quite intuitive. Taking my Golf as an example: Locate the light control knob on the left side of the driver's seat, first turn it to the position for parking lights or low beam. Then look at the center or side of the knob, where you'll find a small button or a section of the knob with a fog light symbol. Press the button with the front fog light symbol (light lines pointing to the lower left), and the front fog lights will turn on; press the button with the rear fog light symbol (light lines pointing to the lower right), and the rear fog lights will activate. The dashboard will correspondingly display a green front fog light icon and an orange rear fog light icon. Note that you must first turn on the parking lights or low beam to activate the fog light function. In foggy conditions, turning on the front fog lights enhances close-range illumination, while the rear fog lights make your vehicle more visible to those behind you. They are very useful in rain or heavy fog, but remember to turn them off promptly when visibility improves, especially the glaring rear fog lights.

When I drove the old Lavida, the fog light switch was located at the top of the light stalk. After turning on the headlights, the entire top of the stalk could rotate: the first position aligned with the three-slash symbol activated the front fog lights, and rotating one more position to the rear fog light symbol would illuminate the rear fog lights. This design was quite clever—just a twist of the finger. In newer models like the Passat, the fog light positions are often integrated into the outer ring of the light knob. Even when the knob is set to the AUTO headlight position, you can still operate the fog light settings. Remember to ensure the headlights or parking lights are on before activating the fog lights—this is due to the circuit interlock design. The rear fog light button pops back after being pressed, but the light remains on; press it again to turn it off.

Current Sagitar owners would like to inform you: There's often a rotating ring on the side of the light stalk. First turn on the low beams, then rotate the side ring to the position with the fog wave icon to activate the front fog lights. Continue rotating to the bottom triangle exclamation mark icon to activate the rear fog lights. The knob clicks into different positions for tactile feedback. Some models have a small button on top of the wiper stalk - the icon showing a glowing car rear indicates the rear fog light button. Key point: check the instrument cluster - front fog lights illuminate a green car with three diagonal lines on the left; rear fog lights show an orange car with three diagonal lines on the right. After activation, always verify the dashboard indicators, especially since rear fog lights are extremely bright and can impair visibility for following vehicles if left on.

The operation of fog lights in vehicles mainly depends on the lighting control area. Taking my Tiguan as an example: After starting the vehicle, first turn to the AUTO mode or manually turn on the low beam. Then observe the center part of the knob, where there are separate front fog light button (three horizontal lines with a downward arrow) and rear fog light button (a semicircle with a vertical line). The illuminated backlit indicator on the button represents activation. Newer models also integrate the all-weather light function, where turning to a special position simultaneously activates the fog lights and auxiliary lighting. After turning on the fog lights, it is recommended to check the rearview mirror. If you see a noticeable red light reflection on the ground, it indicates the rear fog light is successfully activated. The actual effect in rainy or foggy weather is quite significant, as the light can penetrate the fog and form a light carpet on the ground.

To activate the fog lights on a , remember two steps: first, activate the lighting system (at least turn on the parking lights), and then turn on the fog light function. Common designs fall into two categories: older models have an independent rotating ring at the top of the combination switch lever, while newer models feature an integrated knob on the left side of the dashboard. The front fog light symbol consists of curved light rays pointing left with three lines, and the rear fog light symbol has light rays pointing right with three lines. It's crucial to understand the different functions of front and rear fog lights—front fog lights illuminate the road 15 meters ahead during heavy rain or thick fog, eliminating the whiteout effect, while rear fog lights emit a strong red light visible from 500 meters away to prevent rear-end collisions. Notably, using front fog lights in rainy conditions is safer than hazard lights, as hazard lights can easily lead to misjudgment of distance.
