AFS (ADAPTIVE FRONT-LIGHTING SYSTEM)

Bending lamp (exclusive lamp for AFS) turn ON/OFF depending on the steering wheel angle and the vehi-
cle speed, when the headlamp LOW/HIGH lights, and the shift position is at any ranges except P.

Bending lamp supplies efficient light distribution for turning intersection and driving on the curves.

When turning to the left (right), bending lamp left (right) turn ON/OFF while driving forward or backward.
