Delayed Headlamp Illumination Delayed headlamp illumination provides a period of exterior lighting as you leave your vehicle's area. The feature is activated when your vehicle's headlamps are on due to the automatic headlamp control feature described previously in this section, and when your vehicle's ignition is turned off. Your headlamps will then remain on until the exterior lamps control is moved from OFF to the parking lamp position or until a 90 second lighting period has ended. If you turn off the ignition with the exterior lamps control in the parking lamp or headlamp position, the delayed headlamp illumination cycle will not occur. You can customize the vehicle to activate delayed headlamp illumination when your vehicle's ignition is turned off under the conditions described above, or you may choose not to activate this feature under any conditions. You can turn the feature on and off when you perform the following sequence: 1. Turn the ignition key to RUN. 2. Close all the doors. 3. Press and hold the power door lock switch. While holding the door lock switch, cycle the exterior lamps control on and then off two times. 4. Release the power door lock switch. These steps must be carried out in a time period of less than 10 seconds, followed by a delay period of no more than 10 seconds. 5. Then, press and hold the power door unlock switch. While holding the door unlock switch, turn the exterior lamps control on and then off two times. Release the courtesy door unlock switch. These operations must be carried out in a time period of less than 10 seconds. After releasing the door unlock switch, a single chime will be heard if the delayed headlamp illumination function has been disabled; two chimes will be heard if the feature has been enabled. Disconnecting the vehicle's battery for up to a year will not change the programmed operation for this feature. 2-45
