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 does the AFS off light imply when it illuminates?
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. 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 ).
What does AFS on an automobile mean?
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.
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.
How is AFS light operated?
Modern vehicles dynamically change the headlights to try to improve nighttime vision. In this post, we’ll first look at this technology’s benefits. The fundamental building blocks and design issues will then be briefly covered.
Introduction
The goal of adaptive front lighting systems (AFS) is to dynamically change the vehicle’s headlights to provide the driver with the best possible nighttime visibility without endangering the safety of other road users. When the car steers or the road is uneven, the AFS uses stepper motors to regulate the headlight angle. Additionally, the adaptive mechanism seeks to prevent a direct glare from hitting approaching cars. It makes use of headlamps with an array of LEDs.
Some of these LEDs automatically dim depending on where the approaching car will be. In this manner, the driver’s side is dimmed while the area around the approaching car is lit. The position of the approaching vehicle is discovered by the AFS using image sensors. Figure 1 demonstrates how the AFS modifies the headlights to lighten the approaching car’s driver side.
What does the Lexus AWD system do?
In order to increase traction, the Lexus AWD system automatically distributes power between two or four wheels, varying the distribution from 50/50 to 30/70, as necessary. Cornering Control is a component of this technology that can control oversteer and understeer.
What is a system of adaptable lighting?
Understanding how advanced driver assistance systems (ADAS) function is essential to being able to diagnose a problem with the system. You can more accurately determine the system’s potential causes of failure by being aware of what is happening internally. This will avoid replacing components that are not the root of the system’s problem. Let’s examine the adaptive lighting system’s internal operations.
According to the peculiarities of the vehicle, an adaptive lighting system may have one or many functions. Based on the steering angle, the headlamps can be turned to provide improved illumination in curves. The headlights might level themselves. On the basis of the identification of other vehicles in front of them, they may also automatically switch between high and low beam. The system frequently makes use of an in-car camera. Usually, this camera is placed close to the rearview mirror. The headlights are adjusted as necessary when the camera detects oncoming traffic and moving cars in front of the driver.
A safety feature called adaptive lighting helps you see better at night without impacting other drivers. When turning, the system can enable the driver to view more of the corner. As a result, the motorist can see pedestrians, animals, and stopped vehicles more clearly as they are in their route of movement.
Determining how the system works can speed up the troubleshooting process. Installing components that don’t actually solve the issue will be prevented by knowing which system component to test.
How do you use nighttime daytime running lights?
Some models come with an extra set of daytime running lights. In essence, this technology dims the headlights from their normal setting throughout the day to improve visibility for other drivers. It is especially useful for drivers at sunrise and dusk, when glare can make it difficult for them to see other cars. Your daytime running lights must be turned on in order to:
- Put the key in the “on” position.
- Put the headlights in parking light mode, auto light mode, or off.
- If these requirements are satisfied, the system ought to activate automatically.
- If the parking brake is applied, a manual gearbox car’s lights won’t turn on.
- If the transmission is in park, your daytime running lights won’t switch on.

THE TECHNOLOGY BEHIND IT
Adaptive headlights are not permanently locked in place like regular headlights, which are only able to illuminate the area directly in front of you. These headlights use electronic sensors that use your steering angle to determine which way to swivel in accordance with the direction of your car.
WHAT YOU NEED TO DO
Use these headlights as you normally would, and be aware of any objects or other cars they may be shining on, especially when driving around curves. Always look ahead when driving to check for potential risks or impediments.
TIPS FOR USING IT
- It’s a good habit to look toward the white lines on the side of the road in front of you when approaching oncoming automobiles with your high lights on to assist protect you from being blinded.
- Avoid oversteering at all costs or you risk losing control if you don’t respond quickly enough to a hazard.
- As you approach a curve, slow down and exercise caution.
What sensor(s) does the adaptive front lighting system employ, and what module controls it?
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.
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.
Is Lexus AWD reliable?
Performance: The improved traction on AWD cars like the RX and RC is one of the main advantages between Lexus FWD vs. AWD. Challenges: You are better suited to manage icy roads and rocky trails without losing any traction because AWD versions channel power to the precise wheel that needs it.
The Lexus RX is it always AWD?
AWD LEXUS CROSSOVERS AND SMALL SUVS On the bigger NX’s base 300 and 300 F Sport grades, buyers have a choice of drivetrains; the hybrid 300h comes standard with AWD. The hybrid RX 450h and 450hL are AWD-only vehicles, although the RX 350, RX 350L, and RX 350 F Sport offer AWD as an alternative to the normal FWD.
When I start my automobile, why do my headlights rise and fall?
For instance, faulty connections can cause the motor to continuously move the beams up and down. Alternatively, a headlight beam will always level off at the lowest point and remain there. A manual adjustment or a different setting may occasionally be helpful, but these are not long-term fixes and result in a reduction in lighting quality.
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.
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.
