For vehicles with fog lamps, they are controlled by the band located on the middle of the turn signal/multifunction lever.

To use the fog lamps, the ignition must be turned to ON/RUN and the low-beam headlamps or parking lamps must be on.

ON: Turns the fog lamps on. An indicator light comes on in the secondary information center on the hatchback or in the instrument panel cluster on the sedan, when the fog lamps are on. See Fog Lamp Light .

OFF: Turns the fog lamps off. The fog lamps will also turn off when the high-beam headlamps are turned on. When the high-beam headlamps are turned off, the fog lamps will turn on again.

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