Use fog lamps for better vision in foggy or misty conditions.

The fog lamps control is located on the multifunction lever next to the exterior lamp control.

(Fog Lamps): Turning the band to this position will turn the fog lamps on.

When you turn the fog lamps on, the fog lamp light will appear on the instrument panel cluster to indicate that the fog lamps and the parking lamps are on.

If you turn the high-beam headlamps on, the fog lamps will turn off. They will turn on again when you switch to low-beam headlamps.

The ignition must be on for the fog lamps to operate.

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