You don't they have daytime running lights (they are on when the car is on).
Because the car is equipped with daytime running lights
where is the running light sensor on a 2003 grand marque

I believe most GM cars the daytime running lights can be turned off by applying the parking brake.
lights on at all times
The Grand Prix models come with daytime running lights so they are on during the day, but the regular lights are controlled by a sensor and are set to come on in dusk conditions automatically and off when daylight is sufficient.
DRL - Daytime Running Lights (controls the lights and decides which one will work which won't, head lights&fog and etc.) ALC - Automatic Light Control (understands if it is daylight or dark and activates the DRL)
