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 the interior for a period of time after the ignition key is removed from the ignition. The ignition must be off for delayed exit lighting to work. When the ignition key is removed, interior illumination will activate and remain on until one of the following occurs: Delayed Entry Lighting Delayed entry lighting lights your vehicle's interior for a period of time after all the doors have been closed.
