When off, the light switch knob should be in the center position, i.e. straight up and down. The first click to the right(clockwise) is the running lights, and the next and last click adds the headlights. To turn off the lights the knob must be turned to counter-clockwise to the center or "staright up and down position".

Pulling the switch out to the first click with the headlights on low bean turns the fog lights on. In Europe, the second click out adds the rear fog light we don't have in the US.

Hope this helps.
