What is the afsoff switch?
2 Answers
afsoff refers to the flashing indicator light that appears when there is a malfunction in the automatic adjustment system of the headlight beam direction. Below is relevant information about afsoff: 1. Definition of afsoff: The Adaptive Front-lighting System (AFS) adjusts the direction of the headlight beam according to current driving conditions. The system moves the headlight beam left or right based on vehicle speed and steering wheel angle, working in conjunction with the automatic headlight beam direction adjustment system to improve visibility during intersections and turns. 2. Components: Sensors, ECU, lighting control system, and headlights. The vehicle speed sensor and steering wheel angle sensor continuously transmit detected signals to the ECU, which processes these signals, analyzes the data, and outputs headlight angle commands to rotate the headlights by the corresponding angle.
AFSOFF is actually a very practical switch in the car. I have driven several vehicles equipped with this function, and its full name is the Adaptive Front-lighting System Off button. The AFS system allows the headlights to automatically adjust their direction based on your steering angle and vehicle speed. For example, when turning, the lights follow the curve to illuminate blind spots in the bend, enhancing nighttime driving safety. However, sometimes on particularly bumpy roads or when driving on steep slopes, excessive light movement can be uncomfortable or distracting. In such cases, turning off AFS Off fixes the light position, making it feel more stable. It is also suitable for use in vehicle inspection or maintenance modes to avoid interference from automatic adjustments during testing. Nevertheless, keeping it on during daily driving is the safest option, especially in rural areas or on winding roads, as it helps reduce the risk of accidents. Many new models, such as those from Volkswagen or Honda, come equipped with this button, typically located in the control area near the steering wheel. Operation is simple—just press the button—but avoid turning it off in dark environments.
