How do you turn off daytime running lights in a ford explorer 2003?

If the Explorer is running engaging the parking brake is supposed to turn the

daytime running lights off , otherwise the daytime running lights are supposed to shut

off when the engine is shut off .

I have a 2004, Eddie Bauer Explorer. On the light switch itself, there is a selection to turn on or off the day lights, as well as the extended, courtesy lights after ignition is turned off.
