With the headlights on, push the
lever away from you to turn on the
high beams.
Pull the lever toward you to the center
position to turn the high beams off.
Pull the lever toward you and release
it to flash the high beams once.
You can flash the high beams with the
headlights on or off.
AFS (Adaptive Front-lighting System) secures excellent visibility at intersections
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.
However, when vehicle speed is approximately 22 mph (35 km/h) or higher, the cor-
nering lights will not turn on.
●When the shift lever is in R while the headlights are on (low beam), both cor-
nering lights will turn on. This is desi gned to enhance visibility when parking.
