According to the owners manual, AFS would appear to be standard on all models. This is not clear tho.
----------
The AFS adjusts the headlamp dipped beam depending on vehicle direction and speed. It improves visibility when you are driving at night and helps to reduce headlamp glare for oncoming drivers.
The headlamps will also move when the vehicle is stationary and the steering wheel is turned. To prevent headlamp glare for the oncoming traffic, they will only move towards the passenger side of the vehicle.
The system will not operate when you have switched on the daytime running lamps or when you have selected reverse gear.
To activate the AFS when the daytime running lamps are activated, turn the lighting control to position C.
----------
Position C being the headlights on position.
I found this info here...
