How do you adjust the air suspension ride height on a 2003 Lincoln Navigator?

To adjust the air suspension ride height on a 2003 Lincoln Navigator, first, ensure the vehicle is on a flat surface. Use the vehicle's onboard controls to access the air suspension settings, typically found in the driver information center or using a dedicated switch. You can switch between the standard, off-road, and entry/exit modes to raise or lower the vehicle. If manual adjustments are needed, check for any leaks or issues in the air suspension system, as these can affect ride height.
