Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Headlight Beam Level Control
This system calculates changes in the illuminating angle from changes in the vehicle height and axle distance based on the information on the vehicle height detected by the height sensors installed at the front and rear of the vehicle and information on the vehicle speed and acceleration output from the Anti-Lock Brake System (ABS) and traction system or Vehicle Skid Control (VSC) system to reversely operate the reflector by the obtained illuminating angle through actuators in order to always keep the beam axis constant. If an error occurs in this system, the headlight beam level control warning light in the combination meter lights up to warn the driver.
