Delayed Exit Lighting
Delayed exit lighting 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 activates and remains on 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.
