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.

What does VSC on a Lexus stand for?
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.
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.
My AFS light is blinking; 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 ).
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.
Where is the VSC button located?
On both Toyota and Lexus, the VSC button is typically found under the left side of the steering wheel or close to the gear shifter. Some models of cars only feature a skidding car sign, while others have the text VSC on the button.
Can I drive with VSC light on?
In general, it is safe to drive with the VSC light on, and if you drive safely, your car will work just fine. But because the car’s traction control system won’t be working, you should proceed with caution. Additionally, it is advised to correct it right away.
How much does it cost to fix VSC system?
A VSC system can malfunction for a variety of reasons, and fixing it might run you anywhere from $50 to $2000. For instance, it can cost $250 if a defective ABS sensor is to blame. But you might have to invest more than $1,000 if the problem is with the throttle body.
How do I clear my VSC light?
By disengaging and reengaging the VSC system by pushing the VSC button, you can sometimes reset the VSC light. However, there are occasions when an OBD2 scanner is required for the task, and the majority of the time, a problem must be fixed before the codes can be cleared.
Driving with the VSC light is on is it safe?
Vehicle Stability Control, or VSC as it is commonly known, is the stability control system used in Toyota automobiles. By lowering or eliminating the power provided to your wheels, stability control aids in the maintenance of traction and control in your vehicle. By automatically providing brake pressure to up to three wheels, it achieves this. The system’s main objective is to keep your car traveling in the direction of its wheels. Since 2012, at least in the USA, it has become a necessary safety requirement. Naturally, VSC OFF denotes that your Toyota’s stability control is turned off.
VSC Light Easy Fix
Depending on the model year of the Toyota, a button with the same icon as the light in your gauges will be located either next to your shifter or next to your steering wheel. When you’ve found it:
- Ensure that you have come to a complete stop. If you can, put the car in park.
- For a few seconds, hold down the VSC button.
- The indicator lights for TRAC OFF and VSC OFF will turn on. Now both systems are off.
- Once more, press the VSC button. As soon as both lights go out, the systems are back in operation.
If the VSC OFF light is still on, there can be a glitch in your car’s computer or a problem with the VSC system. Bring your car to a Toyota service location near you so a qualified technician can check the codes and identify the problem. Although it is safe to drive your Toyota even with the VSC OFF light on, we advise caution, especially in bad weather.

Why do my Lexus’s VSC and check engine lights come on?
In a Lexus or Toyota, the following are the most typical causes of simultaneous illumination of the VSC Off and check engine lights: defective or damaged gas cap. defective O2 sensor
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.
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:
- Auto-dimming headlights: When the system detects lights from an approaching vehicle, they will automatically adjust from high to low beams.
- Adaptive driving beams: By selectively turning off a portion of the lights, these lights perform like high beams without blinding other drivers.
- When a car is turning at an intersection, cornering lights should be used to shine light 90 degrees in each direction.
- Adaptive front lighting: alters the direction and pattern of the beams in accordance with the direction and speed of oncoming traffic
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.
Is Lexus’ AWD permanent?
The active traction control feature of the Lexus full-time 4WD system works in conjunction with the company’s exclusive TORSEN (torque-sensing) limited-slip center differential and electronic lock to provide the most effective possible power distribution between the axles.
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.
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.
