However, it *could* be something else depending on the exact color and pattern of the flash. To be certain, you should:
* Consult your owner's manual: This is the best source of information for your specific vehicle's warning lights.
* Check the oil level: Use the dipstick to see if the oil is low. If it is, add oil *immediately* (the correct type and amount for your engine, as specified in your manual).
* Observe the light's behavior: Does it flash constantly? Does it flash only under certain conditions (e.g., when idling, accelerating)? This could provide additional clues.
If the light remains on or flashes even after checking the oil level, do not drive the car. Have it towed to a mechanic to diagnose and repair the problem. Ignoring low oil pressure can lead to catastrophic engine failure.
