When you’re driving a Lexus, you might notice the Adaptive Front-lighting System (AFS) feature. AFS is a technology that adjusts the headlights of your Lexus to follow the curves of the road and provide better illumination while driving.
This can be especially helpful when driving on winding roads or in low-light conditions, making your drive safer and more comfortable.
However, some drivers might find AFS distracting or annoying, especially when driving on straight roads or in slow-moving traffic. They might want to turn off AFS to reduce the potential for distraction and improve their driving experience.
In the following sections, we’ll take a closer look at what AFS is and how it works, when it’s a good idea to turn it off, and how to turn it off in your Lexus vehicle.
What is AFS in Lexus Vehicles?
AFS, or Adaptive Front-lighting System, is a feature that is commonly found in Lexus vehicles. AFS is a technology that adjusts the headlights of your Lexus to follow the curves of the road and provide better illumination while driving.
The AFS system uses sensors to detect the speed of your vehicle and the angle of your steering wheel to adjust the headlights accordingly.
The benefits of AFS for driving safety and visibility are numerous. By following the curves of the road, the headlights provide better illumination for the driver, improving visibility and reducing the potential for accidents. AFS can also help reduce the risk of eyestrain or fatigue, making driving more comfortable for the driver.
When you’re driving in a curve or a turn, the AFS system automatically adjusts the headlights to follow the curve, illuminating the road ahead of you.
This feature is especially helpful when driving on winding roads or in low-light conditions. By adjusting the headlights to the specific angle and direction of the curve, AFS ensures that you have the best possible visibility of the road ahead, reducing the risk of accidents or other safety hazards.
When to Turn Off AFS on a Lexus
While AFS can be a helpful safety feature when driving, there may be situations when turning it off might be necessary or preferred.
For example, some drivers might find AFS distracting or annoying when driving on straight roads or in slow-moving traffic. In these situations, turning off AFS can help reduce the potential for distraction and improve the driving experience.
However, it’s important to note that turning off AFS can also have drawbacks. For example, when driving on winding roads, turning off AFS can reduce visibility in curves or turns, increasing the potential for accidents or other safety hazards. Turning it off might not be necessary for most drivers, as the system is designed to provide a safer and more comfortable driving experience in a variety of situations.
In the end, the decision to turn off AFS should be based on your personal preferences and driving needs. If you find AFS distracting or annoying in certain situations, turning it off might be the best choice for you.
However, if you value the safety and comfort benefits that AFS provides, it’s worth considering the potential drawbacks of turning it off before making a decision.

How to Disable Lexus AFS Warning Light
If you have turned off the AFS (Adaptive Front-lighting System) in your Lexus, the AFS warning light will usually appear on your dashboard. However, you can disable this warning light by following these steps:
- Turn off the engine: Start by turning off the engine of your Lexus and making sure that the headlights are also turned off.
- Locate the fuse box: The fuse box in your Lexus is typically located in the engine compartment, near the battery.
- Remove the AFS fuse: Use the owner’s manual to identify the AFS fuse, which is usually labeled on the inside of the fuse box cover. Remove the AFS fuse using a fuse puller or needle-nose pliers.
- Check the warning light: Once the AFS fuse is removed, check the dashboard warning lights to confirm that the AFS warning light is no longer visible.
- Replace the AFS fuse: When you’re ready to turn the AFS back on, simply replace the AFS fuse in its original position in the fuse box.
Note: Disabling the AFS warning light may prevent you from being alerted to potential issues with your AFS system, such as a malfunction or error. Therefore, it’s recommended that you only disable the AFS warning light temporarily and have your AFS system inspected by a qualified technician if the warning light continues to appear after turning the AFS back on.
Tips for Safe Driving with AFS Turned Off
1. Reduce your Speed
When driving without AFS, it’s important to reduce your speed, especially when driving on curves or winding roads. This will give you more time to react to any unexpected obstacles or hazards.
2. Stay on Well-lit Roads
Stick to well-lit roads when driving with AFS turned off. This will help you see any obstacles or hazards in your path.
3. Avoid Adverse Weather Conditions
If possible, avoid driving in adverse weather conditions, such as heavy rain, fog, or snow. These conditions can significantly reduce your visibility and make it more difficult to see the road ahead.
4. Use Your High Beams
In situations where it is safe and legal to do so, use your high beams to improve your visibility. However, be sure to turn them off when approaching oncoming traffic.
5. Be Aware of Your Surroundings
Pay close attention to your surroundings and any potential hazards or obstacles. This will give you more time to react and avoid any potential accidents.
