Jetta VS5 fog light activation method: The fog light switch is located on the control panel to the left of the driver's seat. After turning on the low beam, pull out the switch to activate the fog lights. All lighting function control buttons are set in the main driver's center console area. The knob corresponds to turning off the lights, automatic mode, parking lights, high/low beams, and rear fog lights. The Jetta VS5 is a compact 5-door, 5-seat SUV with body dimensions of 4419mm in length, 1841mm in width, and 1616mm in height, with a wheelbase of 2630mm. The Jetta VS5 is equipped with a 1.4T turbocharged engine, with a maximum power of 110 kW and a maximum torque of 250 Nm, paired with a 5-speed manual transmission.

I've been driving for over a decade, and the fog light switch on the Jetta VS5 is located on the left-hand stalk near the steering wheel. First, you need to rotate the headlight switch to the parking light or low beam position, which will illuminate the dashboard lights. Then press the fog light button at the end of the stalk: press once to turn on the front fog lights (a green fog light indicator will appear on the dashboard), and press again to activate the rear fog lights (a yellow indicator will light up). This design prevents accidental activation during daytime. Remember to only use fog lights during rain or fog, and they must be turned on when visibility drops below 200 meters. The rear fog lights are particularly bright, so turn them off immediately when weather improves. If you can't find the button, check the lighting section diagrams in the user manual.

To activate the fog lights on the Jetta VS5, follow these two steps: First, rotate the headlight knob on the left stalk to the parking light position to turn on the headlights. Then, press the round button at the end of the stalk—the first press activates the front fog lights, and the second press activates the rear fog lights, with corresponding icons displayed on the dashboard. Note that the rear fog lights emit a very strong red light, which can dazzle drivers behind you, so use them only in heavy fog or rain. Many owners mistakenly think pressing the button alone is enough, but it only works in conjunction with the headlight switch—a common design logic in vehicles. Also, avoid directing high-pressure water directly at the fog lights during car washes, as this can cause moisture to seep into the lamp covers.

When I first drove the VS5, I also explored the fog lights: you need to turn on the headlights first, then rotate the lever on the lower left side of the steering wheel to the low beam position. Then press the button on top of the lever with your finger, and you'll hear a click indicating the fog lights are activated. The front fog lights emit white light to enhance visibility ahead, while the rear fog lights are warning red lights. After turning them on, check the dashboard icon—the one labeled 'FOG' indicates the front fog lights. They are particularly useful in low-visibility conditions at night in suburban areas, but avoid using them on well-lit urban roads as they can distract other drivers. Remember to turn them off after shutting down the car to prevent the fog lights from automatically turning on and draining the during the next startup.

How to operate the fog lights on the Jetta VS5: First, rotate the light stalk to the parking light position. Second, press the fog light button on the top of the stalk. The front fog lights are suitable for illuminating the road surface at a short distance in front of the car, with better penetration than the headlights; the rear fog lights mainly serve as a warning. If you find the button cannot be pressed, check whether the parking lights are already on—this is a safety interlock design of cars. After turning on the fog lights, the temperature of the lights will rise significantly, especially in summer, so it's advisable to take a break after 20 minutes of use. In dusty weather, it is recommended to use the fog lights in combination with the defogging function for better visibility. For car owners who rarely use the fog lights, it's best to test their functionality once every quarter to ensure they are working properly.

Using the fog lights on the Jetta VS5 is straightforward: first turn on the headlights to the parking light mode, then press the fog light button at the top of the left-hand stalk on the steering wheel. Press once to activate the front fog lights, and press twice in quick succession for the rear fog lights. I recommend using only the front fog lights in rainy conditions to illuminate puddles on the road; reserve the rear fog lights for heavy fog. Note that fog lights consume 20% more power than daytime running lights, and prolonged use may affect life. If you forget to turn them off when parking, the fog lights will automatically turn off after locking the car, but they will default to on the next time you start the vehicle—it's best to develop a habit of manually turning them off. For enthusiasts modifying their cars, avoid arbitrarily replacing fog light bulbs with high-brightness ones, as this could damage the electrical circuits.
