G12017 Adaptive Front Lighting System (AFS) Adaptive Front Lighting System (AFS) provides the proper headlight beam level according to the current driving conditions. This system moves the headlight beam left or right according to the turning angle of the tires. The synergy of this system and the automatic headlight leveling system improves visibility at the intersections and curves. The system operates when the vehicle speed increases above 10 km/h (6 mph), and stops when the vehicle speed drops below 10 km/h (6 mph). The system can operate within the limited range of the tires turning angle. Push the button to use the switch box. To cancel the system, push the "AFS OFF" switch. To turn it on, push it again. When the system is canceled, the "AFS OFF" indicator lights up in the instrument cluster. If the system fails, the indicator light in the instrument cluster will flash. If this occurs, have your vehicle checked by your Lexus dealer. After operation, be sure to close the switch box to its original position. 48
