When it's bright enough outside, your headlamps will go off and your front turn signal lamps will come on. To idle your vehicle with the DRL and automatic headlamp control off, set the parking brake while the ignition is in OFF or LOCK. Then start your vehicle. The DRL, headlamps and parking lamps will stay off until you release the parking brake. To turn off the automatic headlamp feature when it's dark outside, move the exterior lamp control to the parking lamp position. Your parking lamps will remain illuminated and your headlamps will turn off. The fog lamps (if equipped) will also be lit if they were on when you switched to the parking lamp position. As with any vehicle, you should turn on the regular headlamp system when you need it. If you turn off the ignition with the headlamp switch 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 headlamp switch on and then off two times. 4. Release the power door lock switch. These operations 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 headlamp switch on and then off two times. Release the courtesy door unlock switch. These steps must be carried out in a time period of less than 10 seconds. Delayed Headlamp Illumination Delayed headlamp illumination provides a period of exterior lighting as you leave your vehicle. 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 headlamp switch is moved from OFF to the parking lamp position or until a 90 second lighting period has ended. 2-43
