The vehicle has fog lamps that provide better visibility in foggy or misty conditions.

The fog lamp button is located in the exterior lamps control.

(Fog Lamps): The headlamps or parking lamps must be on for the fog lamps to work. Press to turn the fog lamps on or off. An indicator light turns on when the fog lamps are on.

Never use the fog lamps in the dark without turning on the headlamps.

When the high-beam headlamps are turned on, the fog lamps turn off automatically. When the high-beam headlamps are turned off, the fog lamps come on again.

Some localities have laws that require the headlamps to be on along with the fog lamps.
