The circle with an exclamation mark is a brake-system warning, the battery shape concerns charging, and the oil-can symbol warns about oil pressure. Know the actual vehicle’s self-test and response instructions. A brake or oil-pressure warning while driving needs a safe stop and investigation; adequate oil level does not prove oil pressure is safe. A warning lamp is not a complete mechanical diagnosis.
