You can idle the vehicle with the lamps off, even when it is dark outside. After starting the vehicle, turn the exterior lamp control band on the multifunction lever to off and then release it. The lamps will remain off until the control band is turned to off again. Twilight Sentinel® also provides exterior illumination as you leave the vehicle. If Twilight Sentinel® has turned on the lamps when you turn off the ignition, the lamps will remain on until: If you turn off the ignition with the exterior lamp switch in the parking lamp or headlamp position, the Twilight Sentinel® delay will not occur. The lamps will turn off as soon as the switch is turned off. The regular headlamp system should be turned on when needed. Exterior Lighting Battery Saver If the manual parking lamps or headlamps have been left on, the exterior lamps will turn off as soon as the ignition is turned off or Retained Accessory Power (RAP) is active. This protects against draining the battery in case you have accidentally left the headlamps or parking lamps on. The battery saver does not work if the headlamps are turned on after the ignition switch is turned to off. If you need to leave the lamps on, use the exterior lamp control to turn the lamps back on. • The exterior lamp switch is moved from off to the parking lamp position, or • A delay time that you select has elapsed. See "Personal Options" under DIC Vehicle Personalization on page 3-73 to select the delay time that you want. You can also select no delay time. 3-18
