With exit lighting, the interior lamps will come on for about 25 seconds whenever you remove the key from the ignition. If you turn the ignition key to RUN or ACCESSORY, the lamps will fade out. The lamps will also fade out if you lock the doors with the power door lock switch or the remote keyless entry transmitter.

When any door is opened, exit lighting is cancelled. The interior lamps will stay on while any door or the liftgate is open, and slowly fade out when all doors and the liftgate are closed.

The interior lamps may stay on for up to 25 seconds after all doors have been closed if they have not been locked. See Delayed Lighting .

To turn the exit lighting feature off or on, see Vehicle Personalization .
