A battery-shaped light while the engine is running can indicate that the charging system is not supplying power as expected. Replacing the battery without checking the cause may leave the underlying problem unresolved.
Watch for accompanying messages, dimming lights, or changes in vehicle operation. If the temperature warning also appears, stop safely and shut off the engine. Contact 12th Street Auto Care Center with the warning details, and follow your vehicle manual's instructions about driving or arranging assistance.
