Which indicator would directly alert you to an overheating exhaust system?

• A. HEST indicator light
• B. Oil pressure warning
• C. Tire pressure warning
• D. Battery alert

Answer: (A)

When you need to know if the exhaust system is getting too hot, you want a warning that is specifically tied to exhaust temperature. The HEST indicator light is designed for Hot Exhaust System Temperature, so it lights up directly when the exhaust is overheated. That direct signal lets you respond quickly to prevent damage or fire risk, making it the most reliable warning for this issue. The other indicators point to different systems: oil pressure warning warns about lubrication, tire pressure warning about tires, and battery alert about electrical power. They’re important for overall safety, but they don’t tell you anything about the exhaust overheating.
