What does the afs off light mean?

The AFS OFF light means the Adaptive Front-Lighting System is currently disabled or not functioning, so the headlights won’t adjust their aim as you steer. This indicator can appear when you deliberately turn the system off, when the vehicle detects a fault, or when operating conditions require the feature to be inactive.

Adaptive Front-Lighting Systems use sensors and motors to swivel or adjust the headlamp beam in response to steering input, speed, and sometimes weather or road conditions. When the indicator shows OFF, it can indicate a user setting, a temporary condition, or a fault in the system. This article explains what the light means, common causes, and how to respond.

How an Adaptive Front-Lighting System works

AFS enhances nighttime visibility by adjusting the direction of headlights as you steer, helping illuminate corners and bends more effectively than a fixed beam. The system is typically integrated with the vehicle’s lighting controls and may rely on sensors, a control module, and motorized headlight assemblies. The exact behavior and controls vary by make and model, but the underlying principle is to align the beam with the road ahead for safer night driving.

When the AFS OFF light can appear

There are several common situations where the AFS OFF indicator may come on. Some are deliberate settings chosen by the driver, while others indicate a fault or condition that disables AFS temporarily or permanently.

• You manually turned AFS off using a dedicated switch or through the lighting controls.


• The system detects a fault in sensors, wiring, the motor, or the control module.


• The vehicle automatically disables AFS in certain modes or conditions (for example, when high beams are selected, or a specific drive mode is active).


• An electrical issue such as a blown fuse, loose connector, or voltage drop prevents AFS from initializing.


• A calibration or sensor issue (for example, a misaligned camera or steering-angle sensor) triggers a fault condition.


• After a battery disconnect or service, the system may require reinitialization or calibration by a technician.

In most cases, the presence of AFS OFF indicates either a manual setting, a fault the system has detected, or a condition that prevents proper operation. If you didn’t intentionally disable AFS, and the light remains on, it’s a sign you should investigate further.

What to do if the AFS OFF light stays on

If the AFS OFF indicator remains illuminated, treat it as a potential safety issue related to night lighting. Follow these steps to diagnose and address the problem.

1. Check the AFS and headlight controls to ensure you have not accidentally turned the system off.


2. Inspect related fuses and electrical connections per your owner’s manual, looking for blown fuses or loose wiring.


3. Note whether other warning lights are present and whether the headlights themselves function properly in normal mode.


4. If you have access to a diagnostic tool, scan for fault codes related to the AFS, headlamps, or steering sensors. Record any codes for reference when you consult a technician.


5. Schedule treatment with a qualified technician or dealership if the light persists. AFS components (sensors, control module, and motors) can require calibration or replacement, and improper operation can affect nighttime visibility.

In summary, a persistent AFS OFF light is a signal that the system is not available for active use due to settings or a fault. Checking the controls, basic electricals, and diagnostic codes can help determine whether the issue is simple to resolve or requires professional service.

Notes for drivers and safety considerations

Because AFS is designed to enhance night visibility, its failure or deactivation can impact nighttime driving safety. If you rely on adaptive lighting for urban or rural night routes, it’s prudent to have the system inspected promptly to restore optimal illumination and ensure compliant operation of the vehicle’s lighting system.

Model-specific considerations

General guidance across brands

The exact behavior of the AFS OFF indicator can vary by make and model. Some manufacturers allow quick reactivation after a temporary fault, while others require professional calibration after certain repairs or battery work. Always consult your owner’s manual for model-specific instructions and recommended service procedures.

Summary

The AFS OFF light signals that the Adaptive Front-Lighting System is not available for use—either due to user settings, a detected fault, or a temporary operating condition. If the light is on without your intentional deactivation, check controls and basic electricals, then seek professional diagnostics to ensure safe nighttime illumination and correct system operation.

What does AFS off mean in my Mazda?

Adaptive Front Lighting System (AFS) (Some Models)
Refer to Exterior Light Warning Indication/Warning Light (Search). The Adaptive Front Lighting System (AFS) can be switched to on/off using the personalization function. Refer to the Settings section in the Mazda Connect Owner's Manual.

Why is the AFS off light on?

If the AFS indicator comes on and starts blinking while driving, pull to the side of the road when it is safe, and turn off the engine. If the AFS indicator keeps blinking, or starts blinking again while driving after turning the ignition switch to the ON (II) position, the AFS is not working properly (see page ).

What does AFS stand for in Lexus?

AFS in a Lexus stands for Adaptive Front-lighting System, which is an advanced headlight system that adjusts the direction of the headlights to improve visibility while turning. It does this by swiveling the low beams left or right based on the vehicle's speed and steering angle. This feature is designed to illuminate the road ahead in the direction of the turn, and can be manually turned off by the driver if needed.
 
This video explains how the Adaptive Front-lighting System works in a Lexus: 56sLexus CanadaYouTube · Mar 15, 2017
How it works

• Steering-based adjustment: When you turn the steering wheel, the system uses the angle of the tires to swivel the low beams in that direction. 
• Speed-based adjustment: The amount of swivel changes with your speed; the system is designed to provide more light into a corner at higher speeds. 
• Automatic leveling: It also includes an automatic leveling control that keeps the beams at the optimal height for proper illumination and to prevent blinding oncoming traffic. 

How to use it

• To enable/disable: Most Lexus models have a button or a setting on the dashboard or steering wheel that allows you to manually turn the AFS system on or off. The "AFS off" message will appear on the dashboard when the system is disabled. 
• To troubleshoot a flashing light: If you see a blinking "AFS off" light, it indicates a problem with the system, such as a faulty level sensor, which is often a relatively simple fix, or another component.
