Delayed Exit Lighting
If it is dark enough outside when you remove the key from the ignition, the interior lamps will turn on and stay on for about 25 seconds. This will give you time to find the door pull handle or lock switches. Once the key is inserted into the ignition, the exit lighting will be cancelled and the lighting will fade out.
