If the car has front fog lamps, these are in the bumper casing below the headlamps.

The fog lights are operated via a button in the light switch module (LSM). An LED in the button illuminates when the fog lights are on.

The light switch module (LSM) is directly connected to the central electronic module (CEM). Power is supplied to the lamps via a direction connected relay on the central electronic module (CEM).
