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.

My AFS light is blinking; 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.
What does the Lexus AFS light mean?
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.
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.
What is Toyota Crown’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.
What does AFS stand for?
The most popular definition of AFS on Snapchat, WhatsApp, Facebook, Twitter, Instagram, and TikTok is “Always, Forever, and Seriously.” AFS. Always, Forever, and Seriously is defined.
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.
- As you approach a curve, slow down and exercise caution.
- 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.
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.
What automobiles feature headlights that can curve?
Many of the vehicles made by high-end manufacturers come with or have adaptable lighting available. Many of the models offered by Porsche, BMW, Audi, Mercedes-Benz, and Volvo include some form of adaptable headlights. Today’s common cars also include adaptable headlights. Even several entry-level cars from Ford, Subaru, Toyota, Hyundai, and Honda offer adjustable headlights. Each model year, there are more car models available with adaptable 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.
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.
- When a car is turning at an intersection, cornering lights should be used to shine light 90 degrees in each direction.
- 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
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.
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 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.

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.
The function of the Lexus adaptive headlights.
With the upcoming release of the updated Lexus RX 450h, which debuts the latest generation of BladeScan adaptive high-beam light distribution, a world-first Lexus headlight technology, these features will be significantly improved.
How does this brand-new technology function? And how does BladeScan outperform current adaptive lighting technologies?
On either side of the car, an array of LEDs are stacked in two tiers, with eight units at the top and 16 units at the bottom, making up the current Lexus adaptive high-beam system. In order to prevent drivers of oncoming cars from becoming blinded, the area of high-beam illumination in front of the automobile is then changed in real-time by adjusting the light output by each diode. Such an array typically provides a controlled lighting region that is precise to 1.7 degrees.
However, BladeScan technology, which is accurate to within 0.7 degrees, provides more exact photometric control of the area of illumination in front of the car. Additionally, it provides a wider distribution of light to illuminate spaces that would typically not be lit by a traditional high-beam system.
While competing systems have significantly increased the number of LEDs in order to improve headlamp resolution, the new Lexus technology in the case of the RX relies on a more practical array of LEDs on either side of the carten. Additionally, each RX headlight’s inner corner houses a small module that houses everything in addition to the well-known triple-eye LED bulbs.
Each BladeScan module has LEDs that project their light diagonally across two blade-shaped mirrors that rotate at a speed of 100 revolutions per minute as opposed to directly forward. The lenses then irradiate the adjusted beam through a lens and onto the road in front of you. The mirrors are employed to accurately manage the shade effect.
Lexus engineers claim that RX drivers will benefit from a wider and more natural dispersion of light thanks to this new technology. Additionally, they must be able to recognize pedestrians near the road’s shoulder at night from a distance of 56 meters (32 metres previously).
