To pass an emissions test on a 2003 Lincoln LS that has driven over 500 miles, you may need to reset the vehicle's computer and complete the drive cycle. Here's a general guide on how to do this:

1. Ensure that the vehicle's engine is cold and has not been running recently.

2. Disconnect the negative battery terminal from the vehicle's battery for at least 10-15 minutes. This will reset the computer.

3. Reconnect the battery terminal.

4. Start the vehicle and let it run for a few minutes to allow the computer to initialize.

5. Drive the vehicle for at least 30 minutes, ensuring to vary the engine speed and driving conditions. This includes:

- Accelerate slowly from a stop.

- Drive at different speeds, from low-speed city driving to higher speeds on the highway.

- Make a few stops during the drive.

- Avoid idling for extended periods.

6. After completing the drive cycle, return the vehicle to where you started and let it sit for a few minutes with the engine idling.

7. Turn the engine off and let it cool down.

8. Once the engine has cooled, the computer should have completed its self-diagnostic tests and stored any necessary emission-related data.

It's important to note that different states and regions may have different emissions testing procedures and requirements, so it's best to check with your local emissions testing center or refer to your state's vehicle emissions inspection regulations for specific details.
