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.

Turn the band to to turn the fog lamps on. The band automatically returns to its starting position when released. The fog lamp indicator light comes on in the instrument panel cluster. See Fog Lamp Light.

To turn the fog lamps off, turn the band to again. The fog lamp indicator light will go 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.
