The inner lights are cornering lights only. They turn on when you put your blinker, but the light they shed are like a fog light and will fade out when you turn or after n-seconds of the blinker on. They also turn on when you reverse.
The adaptive headlight is the mechanism that turn on the main headlamps (HIDs) while cornering. This is speed dependent and at lower speeds will only move the right one I believe (on LHD) when turning.
