Headlight switch push button
Despite reading the manual, I have a small puzzle in regards to the headlight switch (specifically when pressed for fog lights) mine does the following:
With headlights on, press the switch in once ->fog lights illuminate (fog light symbol illuminates blue), press again -> nothing physically happens (a second yellow fog light symbol illuminates on the dash) press again -> fog lights turn off and both foglight symbols on the dash [yellow and blue] turn off.
Question, what is the second option (yellow foglight symbol appears) for?
Any help appreciated, I had a mate stand out front of the car to tell me what happened in case I missed something...
