To help me identify the warning light, please provide:
* A clear picture of the light. This will help me see the exact symbol.
* The color of the light. Is it red, yellow, or another color?
* The exact location of the light. Is it on the left side of the fuel gauge, above it, or below it?
With this information, I can help you understand what the light means and what you should do.
Additionally, it might be helpful to consult your car's owner's manual. It usually has a detailed diagram of all the dashboard lights and their meanings.
