and on curves by automatically adjusting the direction of the light axis of the
headlights according to vehicle speed and the degree of the tire’s angle as con-
trolled by steering input.
AFS operates at speeds of 6 mph (10 km/h) or higher.
●When the steering wheel or turn signal lever is operated while the headlights
are on (low beam), a cornering light w ill turn on and light up the direction of
movement of the vehicle. The cornerin g lights are designed to ensure excel-
lent visibility when making a turn at an intersection.
