The symbol will indicate the system experiencing a problem. Common yellow warning lights include:
* Check Engine Light (often a stylized engine): This is the most common yellow light. It indicates a problem detected by the vehicle's onboard diagnostic system (OBD-II). You'll need to have the code read using an OBD-II scanner (available at auto parts stores) or a mechanic to diagnose the specific issue.
* Brake System Warning Light (often a circle with an exclamation point in it, or a brake caliper): This could indicate low brake fluid, a problem with the braking system, or a parking brake issue. Check your brake fluid level immediately.
* Tire Pressure Monitoring System (TPMS) Light (often a tire with an exclamation point): This indicates low tire pressure in one or more tires. Check your tire pressures.
* Battery Warning Light (often a battery symbol): This indicates a problem with your charging system (alternator or battery).
* Transmission Warning Light (often a gear symbol): This suggests a problem with your transmission.
To get an accurate answer, please describe the symbol of the yellow light or take a picture of it and provide a description. This will allow for a more precise diagnosis. Ignoring a yellow warning light could lead to more serious (and expensive) problems down the road.
