I don't know HOW to do it but I know it can be done. I drove a Tuscan S that was still in the running in stage, the change light was set at 3000. Very bright light too, no way you could ignore it!
If you haven't got the manual, press and hold the menu button, then press the fog light button, and release both together. You can change the setting in this menu area. (press fog light to exit).
