My AFS light is flashing; 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 ). Have your dealer check out the AFS.
How is the AFS on a Lexus ES 350 activated?
Turn the ignition to the ON (II) position and turn on the headlights to activate the AFS. 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.
Why is there an AFS light on a Lexus?
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 my Lexus’ AFS off 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 role does AFS play?
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, how do you turn off the headlights?
207) To turn off the high lights, move the lever back to the center position. 2 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.
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.
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 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.
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
- 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.
- Avoid oversteering at all costs or you risk losing control if you don’t respond quickly enough to a hazard.
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.
How can the AFS light be turned off in a Honda CRV?
This switch is located next to the right vent. To activate or deactivate the AFS, press it. When you turn on the headlights when AFS is off, the AFS indicator illuminates as a reminder.
In the Lexus lx570, what is AFS?
The Adaptive Front-lighting System (AFS) automatically modifies the direction of the headlights’ light axis in response to the vehicle’s speed and the degree of the tire’s angle as controlled by steering input to ensure great visibility at intersections and on curves.
Does front adaptive lighting merit the cost?
Do adaptable headlights make financial sense? According to the Insurance Institute for Highway Safety, adaptive headlights could contribute to the avoidance of up to 90% of nighttime curve crashes. For the cars that have them, insurance firms observe a 510% decrease in crashes.
What distinguishes headlights that are adaptive from those that are not?
According to the Insurance Institute for Highway Safety, the great majority of vehicles do not currently have adaptive headlights (IIHS).
“According to David Aylor, manager of active safety testing at IIHS, many automakers still view good headlights as optional bonuses rather than mandatory safety measures. ” Sunroofs and leather chairs are lovely, but to prevent accidents, you need good headlights.
If you get them used, you may pay close to $1,000. The cost should decrease as more automakers start to include adaptive headlights as standard equipment in new models, and adoption should increase.
Are adaptive headlights therefore worthwhile? That is ultimately up to each motorist to decide. Even if the technology isn’t perfect, if you have the extra cash, it’s always worthwhile to invest in your safety and the safety of those you care about.
Even when the vehicle travels around a bend or ascends a steep climb, conventional headlights illuminate the area directly in front of the driver. Standard headlights are grossly insufficient at night, especially on highways with poor lighting and when navigating curves. They can also blind careless drivers, which exacerbates dangerous driving circumstances.
Additionally, it is the responsibility of the driver to operate the vehicle safely and sensibly. Those who drive too quickly, imprudently, or while they are drowsy, drunk, or otherwise preoccupied cannot be predicted by adaptive headlights.
Nevertheless, adaptive headlights outperform conventional headlights in terms of road danger illumination and can improve driver sight at night. However, the headlights won’t help the driver if he is distracted and has a slower reaction time. However, for drivers who take driving seriously and always follow safe driving habits, adaptive headlights can completely change the way they see the road. Adaptive headlights are an advancement in automobile technology that have the potential to make our roads safer, decrease accidents, and save lives by improving visibility at night and in low light conditions.

An adaptive light is what?
A headlight system called adaptive driving beams uses automatic beamforming and a computer to focus lights in various directions. It can enlighten the road directly in front of you and dim the lights that shine outward and might otherwise blind oncoming motorists.
What module manages the front lighting system that is adaptive?
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:
- 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
- Auto-dimming headlights: When the system detects lights from an approaching vehicle, they will automatically adjust from high to low beams.
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.
