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.

What does my Lexus’ AFS stand for?
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.
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.
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 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.
What is adaptive lighting in cars?
Adaptive headlights typically have bulbs that rotate in the direction of the vehicle’s movement or speed, expanding the driver’s field of vision by pivoting up to 15 degrees as the steering wheel is turned or embedded sensors detect a change in the environment. However, the technology is complicated and may vary between auto manufacturers.
AFS on a 2005 Lexus RX330: What is it?
Along with twisting the steering wheel, the AFS also slightly shifts the low beam headlights to the right or left. When the car is travelling at least 19 mph, this mechanism kicks in. Realistically only perceptible at night on a dark, winding route.
What does the Lexus RX330’s VSC light mean?
Hello, the presence of these lights denotes a problem with the vehicle’s stability control and engine operation. It might be a transmission-related issue in some circumstances, but not always.
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 TECHNOLOGY BEHIND IT
Adaptive headlights are not permanently fixed in place like traditional 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.
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 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.
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.
How does a Mazda CX 5’s AFS get turned on?
Put the low beam position on the lever. The green HBC indicator light goes off. Set the location of the headlight switch. The green HBC indicator light goes out and is replaced by.
