Illuminated entry includes a feature called theater dimming. With theater dimming, the lamps don't just turn off at the end of the delay time. Instead, they slowly dim after the delay time until they go out. The delay time is canceled if you turn the ignition key to RUN or START, so the lamps will dim right away. When the ignition is on, illuminated entry is inactive, which means the courtesy lamps won't come on unless a door is opened. Delayed Exit Lighting This feature illuminates your vehicle's interior for a period of time after the ignition key is removed from the ignition. The vehicle's ignition must be off for delayed exit lighting to work. When the ignition key is removed, interior illumination will activate and remain on until: Delayed Entry Lighting Delayed entry lighting lights your vehicle's interior for a period of time after all the doors have been closed. The ignition must be off for delayed entry lighting to work. Just after all the doors have been closed, the delayed entry lighting feature will continue to work until: D The ignition is in RUN, or D the power door locks are activated, or D an illumination period of 25 seconds has elapsed. If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on since a door is open. Perimeter Lighting Perimeter lighting provides a period of exterior vehicle lighting as the driver and passengers approach the vehicle. Perimeter lighting is only activated when the function is enabled, the doors are closed, the ignition is in OFF and the security feedback feature is in Mode 3 or 4. (See "Security Feedback" in the Index for more information.) The vehicle headlamps and back-up lamps are then activated for a period of 25 seconds or until the ignition switch is turned to RUN. D The ignition is in RUN, or D the doors are locked, or D an illumination period of 25 seconds has elapsed. If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on since a door is open. 2-45
