What I'd Recommend:

• Check Engine Light: This is one of the most common lights and can mean anything from a loose gas cap to a serious engine problem. If it's on, have it checked by a professional.
• Service Engine Soon Light: Similar to the Check Engine Light but indicates that there's a serious issue that needs immediate attention.
• Tire Pressure Monitoring System (TPMS) Light: This light comes on when one or more tires are significantly underinflated. Check each tire’s pressure regularly, and if the light stays on, have it inspected.
