The cooling system light is on.
I think you are referring to the Engine Temperature Light. This light stays on until the normal operating temperature is reached. It should be on when the engine is cold, and then go out after a few minutes of driving. On the other hand, if you are talking about the Low Coolant Light, you may have a problem. This light illuminates to warn the driver that the coolant level is low, and typically indicates a leak somewhere in the cooling system. If this is the case, I suggest you have a professional mechanic, such as one from YourMechanic, diagnose the cause of your temperature warning light, and recommend the best path to repair.
