What does an exclamation mark on the speedometer mean?

[EdenLee]

An exclamation mark on the speedometer is the tire pressure monitoring fault signal indicator, indicating a detected tire pressure fault. The reasons for an exclamation mark on the speedometer are: 1. A punctured tire; 2. Prolonged driving or failure to replenish tire pressure in time; 3. Faulty tire pressure sensor; 4. The tire pressure module was not reset after a tire change or repair. The methods to address an exclamation mark on the speedometer are: 1. Display the tire pressure and temperature readings on the dashboard to check for any abnormalities; 2. Inspect the underinflated tire for leaks; 3. Check if the tire pressure monitor is malfunctioning.
