There is a switch especially for the foglights under the dash towards the driver's side door left of the steering wheel. The foglights will come on only if the low beams or the park lights are on. When you change from low beams to high beams the foglights will go off. Also when you turn the car off the fog lights go off too.
the dash and radio lights are supposed to dim when the headlights come on. Make sure you have the brightness of the dash lights turned up as much as possible.

You have to get under the car and change it that way.
I like to get on a dark road and adjust them with the screws on top and sides of the lights but don't blind the driver comming at you.
