Operating the lights and windshield wipers AFS AFS (Adaptive Front-lighting System) improves visibility at intersections and on curves by automatically adjusting the direction of light axis of the headlights according to vehicle speed and the degree of the tire angle that are controlled by steering input. Operates at speeds of 6 mph (10 km/h) or higher. n Deactivating AFS On/off The indicator turns on when the AFS is deactivated. 2 When driving n Daytime running light system l To make your vehicle more visible to other drivers, the headlights turn on auto- matically (at a reduced intensity) whenever the engine is started and the parking brake is released. Daytime running lights are not designed for use at night. l Compared to turning on the headlights, the daytime running light system offers greater durability and consumes less electricity, so it can help improve fuel economy. n Headlight control sensor The sensor may not function properly if an object is placed on the sensor, or anything that blocks the sensor is affixed to the windshield. Doing so interferes with the sensor detecting the level of ambient light and may cause the automatic headlight system to malfunction. 199
