The symbol of a car with a wrench inside it on your 2005 Buick LaCrosse's dashboard indicates a
Check Engine Light. It means the car's onboard diagnostic system (OBD-II) has detected a problem that needs attention. The specific issue could be anything from a loose gas cap to a more serious engine malfunction.
You'll need to have the car scanned with an OBD-II code reader (available at auto parts stores) or take it to a mechanic to determine the exact cause of the light. Ignoring the light can lead to further damage and potentially expensive repairs.
