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 a Lexus’ AFS off signify?
14:15 on August 28, 2018. 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.
My AFS light is on, why?
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 ).
AFS off light: What does it mean?
The AFS, or automated headlight system, is a feature of your Lexus. It has actuators, sensors, and modules that enable the headlights to move as the automobile is turned. You may have accidentally turned the system off; check your dash for a switch marked “AFS OFF.” If you don’t have such a switch, you’ll need to take it to a Lexus dealer or a non-dealership facility that has a factory scan tool for Toyota/Lexus vehicles.
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.
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.
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
- Avoid oversteering at all costs or you risk losing control if you don’t respond quickly enough to a hazard.
- 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.
- As you approach a curve, slow down and exercise caution.
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.
How do I know when to replace the oil in my Lexus?
When the Lexus Maintenance Required light on your dashboard illuminates, it indicates that your car needs an oil change, a tire rotation, or other type of standard maintenance. Depending on your Lexus model, this typically happens every 3,500 to 5,000 kilometers.
What is the schedule for Lexus maintenance?
The general rule of thumb is that you should bring your Lexus in for service every 7,500 miles or at least once a year, whichever comes first. However, the service frequency for your particular Lexus car may vary.
My automatic headlights won’t switch off, why?
- Battery
- Fuse
- Switch
- Bulb
- Wiring
Your battery, fuse, and headlight bulbs are all operating properly if your headlights are on and won’t turn off. The solution is to isolate the switch or the wire, whichever is the issue.
Let’s examine each of the potential causes in turn:
Do Lexus lights automatically turn off?
Either manual or automatic control is available for the headlights. The running lights come on during the day. The instrument panel lights, daytime running lights, parking lights, taillights, side markers, and license plate lights switch on. All of the aforementioned lights (apart from daytime running lights) turn on, along with the headlights.
My automatic headlights won’t turn on; why?
A fuse, headlamp relay, headlight switch, dimmer switch, or a wiring issue are the most likely culprits. A blown fuse is essentially the only cause that can be easily fixed. Find the headlight circuit’s primary fuse by consulting your owner’s manual, then swap it out with a new fuse with the same amp rating.
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.
How can I tell whether my headlights are adjustable?
Going on a nighttime drive could reveal whether your automobile has adaptive headlights. Your headlights are probably adaptive if you notice that they change their angle or brightness on their own. Some manufacturers mark their adaptive headlamp system with text or an icon inside the lens. When the headlights are off, take a peek around to see what’s there. If your car was made before the early 2010s, its headlights are probably not adaptive because adaptive headlights have only recently started to become more prevalent.
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.
