Please provide the following details:
* Where exactly is this light located on the dashboard? Is it on the left, right, center, or in a specific cluster?
* What does the light look like? Is it a single light, multiple lights, a symbol, a word, or something else?
* What color is the light? Is it red, yellow, green, or another color?
* Is there anything else going on? Are any other warning lights on? Is the car behaving strangely?
Once I have this information, I can help you understand what the light means and what you should do.
