What does a warning light on the dashboard indicate?

• A. The engine oil level is low
• B. The battery is charging
• C. A possible system problem
• D. The airbags are deployed

Answer: (C)

Warning lights are signals from the car’s onboard computer that something in a vehicle system may be outside the normal range and needs attention. They aren’t describing a single fixed condition, but alert you that a subsystem could be failing or in need of service. That makes it the best fit for a general dashboard warning: it communicates a possible system problem that you should check soon. Specific indicator lights, like one that points to low oil pressure, another to a charging system issue, or an airbag/SRS warning, are examples of particular problems. When a warning light comes on, you should slow down safely, consult the owner’s manual for the symbol, and have the vehicle inspected to diagnose and fix the underlying issue.
