What does the 'H' display mean in Tesla?
1 Answers
Tesla displaying 'H' refers to the water temperature gauge. Here are the relevant details: Automotive water temperature gauge: Typically uses a 60°C–120°C scale or is labeled with Cold (C)–Hot (H). When a car engine operates, gasoline combustion generates significant heat, partially expelled through the exhaust pipe and partially transferred to the engine block. Excessive block temperature can cause thermal expansion and damage to components, necessitating water circulation for cooling. High water temperature indication: Normally, the needle points to the middle of the gauge when the temperature is optimal (varies by model; consult the warranty manual). However, the gauge's right side features a red zone marking the high-temperature range. If the needle approaches this zone, it indicates elevated water temperature. Continued driving without intervention may easily lead to coolant boiling ("overheating").
