However, it *does* have some basic safety features that indirectly protect the engine:
* Low oil pressure warning light: This light illuminates if the oil pressure drops too low, indicating a serious problem that could damage the engine if ignored. The driver must then address the issue promptly.
* Overheating warning light: Similar to the oil pressure light, this alerts the driver to a potentially engine-damaging overheating situation. Again, driver action is required to prevent serious damage.
These are essentially warning systems, relying on the driver to react. There's no automatic engine shutoff to prevent damage. The responsibility for preventing engine damage in a 2003 Expedition rests primarily with the driver maintaining proper fluid levels, avoiding overheating, and addressing warning lights immediately.
