Engine / check engine
An engine or emissions-control warning generally means the engine management system has detected a fault. Many manufacturers treat a flashing light as more urgent than a steady one.
Generally: Avoid hard acceleration and have it inspected. If it flashes or the engine runs roughly, stop safely and follow your manual.
