The front fog lights can be used in combination with the high/low beam headlights or the parking lights. Both fog lights also illuminate when the vehicle is backing up.
Press the button to turn the fog lights on/off. The indicator symbol 
in the instrument panel illuminates when the front fog lights are on.
Corner illumination
The front fog lights include corner illumination, which temporarily provides extra light to the front left or right of the vehicle (depending on which way the vehicle is turned) when making a sharp turn at low speeds (for example, when turning into a parking space) or when the turn signals are used.
This function is activated when the high or low beam headlights are used and the vehicle's speed is under approx. 20 mph (30 km/h).
