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 continues to work until one of the following occurs:
• The ignition is in ON/RUN.
• The doors are locked.
• An illumination period of about 25 seconds has elapsed.
If during the illumination period a door is opened, the timed illumination period is canceled and the interior lamps remain on.
