General guidance

Written by CarFactBook. Symbols and meanings differ between manufacturers and models; your owner's manual is the authority for your exact car.

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.
