Entry lighting includes a feature called theater dimming. With theater dimming, the lamps do not 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 ON/RUN or press the power door lock switch. The lamps will dim right away. When the ignition is on, illuminated entry is inactive, which means the courtesy lamps will not come on unless a door is opened. Delayed Exit Lighting This feature illuminates the interior for a period of time after the key is removed from the ignition. The ignition must be off for delayed exit lighting to work. When the key is removed, interior illumination will activate and remain on until one of the following occurs: Delayed Entry Lighting Delayed entry lighting illuminates the interior for a period of time after all the doors have been closed. The ignition must be off for delayed entry lighting to work. Immediately after all the doors have been closed, the delayed entry lighting feature will continue to work until one of the following occurs: • The ignition is in ON/RUN. • The power door locks are activated. • An illumination period of 20 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 because a door is open. Parade Dimming The instrument panel has an added feature called parade mode. It automatically prohibits the dimming of the instrument panel displays during the daylight while the headlamps are on so that you will still be able to see the displays. • The ignition is in ON/RUN. • The doors are locked. • 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 because a door is open. 3-18
