As installed in the Lexus RX 450h, Lexus’ Intelligent Adaptive Front Lighting System is a driver assistance that modifies the direction of the headlights in reaction to steering inputs and vehicle speed, effectively pointing the low-beam headlights towards the corner and improving your view.
The system is set to be activated by default, but if you’d like to temporarily turn it off, follow the instructions in the tutorial video below or continue reading for a step-by-step ‘how to’.
- Press the “MENU” button on the Lexus RX’s steering wheel, then use the arrow buttons to cycle through the options until “AFS” appears on the dash display.
- By pressing the “ENTER” button on the steering wheel, the system is turned off and the dash display indicator changes to “AFS OFF.”
- To return to the main display, click the “MENU” button one more time.
- Repeat the process to change the display from “AFS OFF” to “AFS ON” to re-activate the system. Resuming operation is the Intelligent Adaptive Front-Lighting System.

Why is the blinking AFS off light on?
When driving with the ignition switch in the ON (II) position, if the AFS indicator blinks continuously or blinks once more, the AFS is malfunctioning (see page ). Have your dealer check out the AFS. This switch is located next to the right vent. To activate or deactivate the AFS, press it.
What does the Lexus AFS light mean?
The term “adaptive front-lighting system” (AFS) refers to headlights that turn in the direction a car is turning, illuminating more of the road in that direction rather than straight ahead.
Many automakers, including Honda, Mazda, Toyota, and others, refer to adaptive front illumination. They are also known as adaptive headlights or curve-adaptive lights, and other manufacturers have their own brand names for them, like the Genesis Adaptive Cornering System and the Porsche Dynamic Light System.
What role does AFS play?
A well-illuminated field of view is one of the most crucial elements in reducing driver tiredness and enhancing safety during nighttime driving. According to the conditions of the road, the Adaptive Front-lighting System (AFS) improves the distribution of headlight light. The device directs the low-beam headlights in the direction the driver desires to go based on vehicle speed and steering input.
The technology improves the driver’s field of vision and visibility around curves and at intersections during nighttime driving by illuminating a greater distance and brighter than halogen headlights do. When combined with auto-leveling, the technology provides a consistent light distribution that is unaffected by the location of the vehicle. When a car’s back is loaded down with a lot of people or luggage, its position varies when driving over a bump or up a slope, and the system maintains the lighting axis, it helps keep drivers of incoming vehicles from being blinded.
Do adaptive headlights merit the expense?
Do adaptable headlights make financial sense? According to the Insurance Institute for Highway Safety, adaptive headlights could contribute to the avoidance of up to 90% of nighttime curve crashes. For the cars that have them, insurance firms observe a 510% decrease in crashes.
On a Lexus IS250, how do you turn the headlights off?
Turn on the high lights by pulling the lever in your direction. To turn them off, pull back on the lever. With or without the headlights on, the high beams might flash.
What is Toyota’s AFS?
To enhance vision while cornering at night, intelligent AFS reroutes low-beam light units in line with the steering angle and vehicle speed.
Bits of Knowledge
Depending on the cornering direction and the nation in which you reside, the angle of the irradiation axis can be altered. These variations exist because, for right-hand drive vehicles, the left light is designed to illuminate a wider area than the right light. Toyota has therefore made the left light less movable to prevent blinding oncoming motorists.
How can I determine if I have AFS?
When you start the car with the lights on, if your lights move left and right before immediately returning to the center, you have AFS. According to my recall, the AFS won’t work when the car is at a stop; following initial calibration, the lamps must move when the car is going.
Exists ambient lighting in a Lexus?
Every interior feature of the ES has been created with you in mind, making it as roomy as it is elegant. The interior of the ES is more inviting and comfortable than ever before, with modern in-cabin technologies and subtly created accents of luxury.
ACCESS YOUR FAVOURITE APPS
You can smoothly combine your digital preferences into your travel thanks to Apple CarPlay4 and Android AutoTM4 compatibility. Through your smartphone apps6, you can listen to your custom playlists, resume your favorite podcast, and browse your list of saved places. A 12.3-inch multimedia display screen makes all of this readily available.
Advanced Sound Technology
The Mark Levinson5 Premium Surround Sound System, available on the Sports Luxury grade and as an upgrade option on the F Sport grade, minimizes obstacles and produces rich, precise sound that envelops all passengers, regardless of your choice of audio.
Ambient interior illumination
Only the ES 300h Luxury Enhancement Pack and ES 300h Sports Luxury grade with Walnut and Bamboo decoration panel are available with LED ambient lighting.
Create a soft glow that can be adjusted to fit personal tastes by indirectly lighting the lower instrument panel, front and back door trim, and the interior of the vehicle.
Independent climate control
S-FLOW By restricting airflow to the areas of the car that are occupied, control keeps the interior comfortable and improves fuel efficiency. Fresh air is helped to fill the cabin via the NanoeX Technology. The Sports Luxury grade’s strong air conditioning system offers three zones of independent temperature adjustment for the driver’s seat, front passenger’s seat, and back seats. The rear center armrest neatly houses a control panel for passengers in the back seats.
BE SURROUNDED BY TECHNOLOGY
The ES interior is loaded with cutting-edge technologies that are thoughtful and intelligent and anticipate your wants. Enjoy a variety of entertainment and information services that are streamed to you and your Lexus by easily connecting to your mobile devices via Apple Carplay4 and Android AutoTM4.
Convenient control panel
The Sports Luxury grade rear seats have an integrated control panel that lets passengers change the audio system, seat recline, and other settings, as well as a center armrest with useful cupholders.
What module manages the front lighting system that is adaptive?
The AFS control module manages the adaptive front illumination system (AFS). The auto leveling function, which moves the headlight optical axis up or down in response to variations in load and passenger situations, is controlled by the AFS control module.
What is control of adaptive lighting?
To increase the safety of nighttime transportation, a new lighting concept called Adaptive Light Control (ALC) is being developed. By continuously adapting the headlamps to the current driving situation and environment, ALC enhances the headlamp lighting. The transition from offline to online (real-time) simulation of light distributions in the driving simulator has been completed successfully in order to ensure rapid prototyping and early testing. The interactive creation of novel light distributions in various driving scenarios and environments was made possible by this real-time simulation. To enable additional testing under real-world driving situations, the solutions are immediately ported to actual vehicles.
Results of the development of moveable headlights are reported in this study. Path prediction based on vehicle dynamics and navigation system route vectors is used to regulate these headlights. An introduction of the fundamental idea behind the Adaptive Light Control system is provided, along with an illustration of the differences between static and dynamic light distributions.
Why should I check my adaptive headlights?
The adaptive lighting warning light indicates a problem with the front automobile headlights’ automatic operation, which could be brought on by dirt.
