Delayed Headlamps The delayed headlamps feature provides a period of exterior lighting as you leave the area around your vehicle. The feature is activated when the headlamps are on due to the automatic headlamps control feature described previously in this section, and when the ignition is turned off. Your headlamps will then remain on until the exterior lamps control is moved to the parking lamps position or until either a 30 second or 60 second lighting period has ended. If you turn off the ignition with the headlamps switch in the parking lamps or headlamps position, the delayed headlamps cycle will not occur. To disable the delayed headlamps feature or change the time of delay, see Vehicle Customization Settings on page 3-96. Fog Lamps If your vehicle is equipped with fog lamps, the button is located on the instrument panel next to the exterior lamps control wheel to the left of the steering column. Your ignition must be in ON for the fog lamps to illuminate. To turn the fog lamps on, press the FOG button. A light will come on in the button to let you know that the fog lamps are on. Press the FOG button again to turn the fog lamps off. The ignition must be ON and the parking lamps must be on for your fog lamps to work. The fog lamps will go off while you change to high-beam headlamps. 3-16
