SWITCHES Automatic headlight leveling system (vehicles with discharge headlight only) Adaptive front-lighting system 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 steering wheel. 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 rises above 30 km/h (18 mph), and stops when the vehicle speed drops below 5 km/h (3 mph). The system can operate within the limited range of the steering wheel turning angle. Vehicle position changes according to loading condition, passengers getting on and off, vehicle acceleration and deceleration, etc. However, the headlight beam level is always maintained automatically by the system at the proper level so that your headlights do not dazzle other road users. If this system fails, the warning light in the instrument cluster comes on. If this occurs, have your vehicle checked by your Lexus dealer. If you replace the rear suspension, contact your Lexus dealer to check the automatic headlight leveling system and headlight beam level. 55
