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?
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.
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.
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.
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 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 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.

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.

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:
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.
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.
How can the oil life of a Lexus RX 350 be checked?
How to Check Your Car’s Oil Level
- Put your car in park on a flat surface, and make sure the engine is off (you’ll want to give the engine some time to cool).
- Next, look for the dipstick in the hood of your car.
- Take the dipstick out.
- Completely reinstall the dipstick after this procedure.
What does front lighting that is advanced mean?
A word used to describe lights that can automatically adjust to shifting driving circumstances is “advanced forward lighting system.” A variety of sophisticated forward illumination systems are available:
- Adaptive driving beams: By selectively turning off a portion of the lights, these lights perform like high beams without blinding other drivers.
- Adaptive front lighting: alters the direction and pattern of the beams in accordance with the direction and speed of oncoming traffic
- Auto-dimming headlights: When the system detects lights from an approaching vehicle, they will automatically adjust from high to low beams.
- When a car is turning at an intersection, cornering lights should be used to shine light 90 degrees in each direction.
As the vehicle turns a bend, the headlights automatically follow the arc of the road.
At an intersection, the car is making a right turn. It can see the path it will travel thanks to the right headlight’s illumination of the intersection’s road.
The car’s headlights dim as it gets close to an approaching vehicle, then they brighten again once the approaching vehicle has past.
As the car passes an approaching vehicle, a portion of its right headlight dims to prevent blinding the approaching driver.
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
- As you approach a curve, slow down and exercise caution.
- 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.
