It means your coolant level has become too low to provide adequate cooling for the internal workings of the engine. To avoid overheating, the sensors shut the engine down. Every car owner needs to check all their engine fluid levels at least once a week. Engines need this kind of attention too - after all, they are only mechanical items and can only work as good for you as we keep them operating properly and with all the fluid levels where they are supposed to be. This also helps to prevent future problems. Get friendly with your engine - Be nice to it and it will be nice to you.
