Fog Lamps (If Equipped) Use the fog lamps for better vision in foggy or misty conditions. The fog lamp button is located to the left of the steering wheel on the instrument panel. Press the button again to turn them off. If you turn on the high-beam headlamps, the fog lamps will turn off. They'll turn back on again when you switch to low-beam headlamps. When the Twilight SentinelR is on and the fog lamps are turned on, the fog lamps, headlamps and parking lamps will remain on. The ignition must be on for the fog lamps to operate. Cornering Lamps The cornering lamps come on when the headlamps or parking lamps are on and you signal a turn with the multifunction lever. They provide more light for cornering. When you press the fog lamp button, a fog lamp symbol in the button and the fog lamp light on the instrument panel cluster will come on to indicate that the fog lamps and the parking lamps are on. 2-53
