If your Lexus AFS light is on, it means that there is a problem with the Adaptive Front Lighting System. This system uses sensors to adjust the headlights based on driving conditions. If the light is on, it means that the system is not working properly and needs to be reset.
To reset the AFS light, follow these steps:
1. Turn off the engine and open the hood.
2. Disconnect the negative battery terminal.
3. Wait for at least five minutes before reconnecting the negative battery terminal.
4. Start the engine and check if the AFS light is still on. If it is, take your vehicle to a Lexus dealership or qualified repair shop for further diagnosis and repairs
