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.

What does my Lexus’ AFS stand for?
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.
My AFS light is flashing; why?
The adjustable front lighting system (AFS) aids in increasing visibility while driving at night.
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.
AFS Lexus is250: What is it?
In order to prevent the headlights from pointing too high if there is weight in the back, AFS adjusts the headlamp level to how the vehicle is sitting. You cannot disable the adaptive system because it must be present by law in any car equipped with LED or HID lighting.
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.
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.
How does AFS function?
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.
Are Lexus’ headlights adaptive?
An major innovation is highlighted in the news releases from Lexus Global, Europe, and even Australia for the 2020 RX refresh: the inclusion of the first-ever BladeScan Type Adaptive High-beam System (AHS).
This is how it goes:
In a first for the automotive industry, BladeScan technology has been added to Lexus’ innovative LED Adaptive High-beam System (AHS) to improve nighttime driving safety. A lens receives light from a lens that is delivered to two blade mirrors that are spinning quickly from an LED source. This light illuminates the road in front of you. By coordinating the rotation of the blade mirrors with the on/off of the headlights, the dispersion of light is accurately regulated.
As a result, RX drivers can see dimly lit areas like road shoulders and spot pedestrians and traffic signs far earlier without compromising their overall visibility or blinding cars going the other way. With BladeScan technology, pedestrian identification at night has increased to 56 meters (184 feet) in front of the Lexus, up from 32 meters (105 feet) with the prior system (Array-type AHS).
The aforementioned picture plus this all-too-brief film serve to better demonstrate the concept:
However, why aren’t the United States and Canada using this innovative technology?
You can hold the 1967 law governing vehicle headlights, U.S. Federal Motor Vehicle Safety Standard No. 108, responsible. The main problem with the BladeScan AHS is that there is only room for one low beam and one high beam option. No intermediate settings are allowed, using both low and high beams at once is prohibited, and the low-beam headlight candlepower restrictions are insufficient.
FMVSS-108 has previously undergone revisions and updates, however the procedure moves slowly and necessitates a plethora of research, assessments, official evaluations, public hearings, comment periods, and input from interested parties.
Toyota, the parent company of Lexus, took the initiative to legalize fully adaptive headlights in the US back in 2013, and Audi and BMW followed suit in 2016 and 2017, respectively. The problem is still unresolved, as accounts from October 2018 and April 2019 serve as a reminder.
But why, despite having more tolerant headlight laws, does Canada have to deal with this American bureaucracy? A hunch would be that the Canadian facility in Cambridge, Ontario will serve North America while the Kyushu plant in Japan will produce Lexus RXs with BladeScan headlights.
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.
Purpose
The user is alerted by the AFS OFF indication light when the adaptive front lighting system (AFS) is halted or experiences a problem (AFS).
Function
The AFS OFF indicator light turns on when the adaptive front lighting system (AFS) or the headlamp auto leveling system is turned off, and it flashes when either of those systems experiences a problem.
Operation
NOTE:
The AFS control module turns on the ignition (engine on or off) and illuminates the AFS OFF indicator light for three seconds to test the light bulb. It then alerts the user that the light bulb is fine.
When an issue with the adaptive front lighting system (AFS) arises or the headlamp auto leveling system is stopped, the AFS control module sends a signal to the instrument cluster that requests the illumination or flashing of the AFS OFF indication light.
Based on the request signal for AFS OFF indicator light lighting or flashing, the instrument cluster turns on or flashes the AFS OFF indicator light.
Why does a Lexus have VSC?
VSC, or “Vehicle Stability Control,” is a safety function in your Lexus ES that aids in preventing skidding if you lose traction when driving through Long Beach.
What does Lexus’ ECT snow mean?
If at all feasible, we advise keeping off the roads when it’s icy. However, if you must brave the bitter cold while driving on snowy or icy streets, the following modern systems can keep you safe.
Snow mode on an electronically controlled transmission (ECT) throttle response is slowed down for more gradual acceleration on ice and snow to help prevent wheel spin. Additionally, the transmission will change into a higher gear more quickly than in regular mode. The road conditions we recently passed through were ideal in this situation.
The ABS sensors are used by TRACTraction Control System (TRAC) to continuously track each wheel’s rotational speed. The algorithm instantly determines the optimal approach to regain traction as soon as they notice that one or more wheels are starting to slip. The brake actuator then applies the necessary amount of braking pressure to the best-suited wheel (or wheels) until traction is regained, after which the engine’s computer control unit adjusts the throttle as necessary. Only shut off if you’re stranded and you need to shake the car to get out.
Vehicle Stability Control (VSC) helps you when you turn too quickly or have to brake hard in the middle of a corner. Sensors track and compare speed, steering angle, yaw rate, and deceleration continually. When the system detects a loss of control, VSC intervenes and temporarily sets the amount of braking force applied to each wheel individually. Additionally, until the tendency of the front to go wide (understeer) or the rear to break away (oversteer) is controlled, the throttle is moderated.
Please don’t hesitate to contact our Park Place Lexus Technology Specialists at Park Place Lexus Grapevine and Park Place Lexus Plano if you have any questions about how the technology features in your Lexus vehicle work.

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.
How can I turn on my Lexus ES 350 with AFS?
Turn the ignition to the ON (II) position and turn on the headlights to activate the AFS. When it is safe to do so, pull over to the side of the road and turn off the engine if the AFS indication illuminates and begins blinking while you are driving.
