Your vehicle is equipped with an illuminated entry feature.
When a door is opened, the dome lamps will come on if the DOME OVERRIDE button is in the out position. When the doors are closed, the lamps will stay on for a short period of time and will turn off automatically. If you use your keyless entry transmitter, if equipped, to unlock your vehicle, the interior lamps will come on for a short time whether or not the DOME OVERRIDE button is in the out position.
