Reset engine light on Kia rio 2003?

To reset the engine light on a 2003 Kia Rio, you can disconnect the battery for about 15 minutes, which will clear the engine codes and reset the light. Alternatively, you can use an OBD-II scanner to read and clear the diagnostic trouble codes (DTCs) that triggered the light. If the light comes back on after resetting, it indicates there is an underlying issue that needs to be addressed. Always ensure you diagnose and fix the root cause of the problem rather than just resetting the light.
