What does the low coolant message on your 2004 Saturn Ion mean?

The low coolant message on your 2004 Saturn Ion indicates that the engine coolant level is below the minimum required threshold. This could be due to a leak, evaporation, or insufficient coolant added during maintenance. It's essential to address this warning promptly, as low coolant levels can lead to engine overheating and potential damage. Check the coolant reservoir and refill it if necessary, and investigate any possible leaks.
