Where is the tire pressure monitoring displayed in the 2021 Audi Q3?

The tire pressure monitoring in the 2021 Audi Q3 is displayed on the instrument cluster. The working principle of the tire pressure monitoring is as follows: it uses pressure sensors installed in the tires to measure the tire pressure, and wireless transmitters to send the pressure information from inside the tires to the central receiver module. Tire pressure monitoring automatically monitors the tire pressure in real-time while driving and alerts the driver in case of tire leaks or low pressure to ensure driving safety. Common tire pressure monitoring methods: Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. Wireless transmitters send the pressure information from inside the tires to the central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts the driver when the tire pressure is too low or there is a leak. Indirect tire pressure monitoring: When the pressure in a tire decreases, the weight of the vehicle causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. Indirect tire pressure monitoring systems actually rely on calculating the rolling radius of the tires to monitor the pressure.
I've been driving my Q3 for over two years and have become quite familiar with the tire pressure monitoring system. In the 2021 Q3, the tire pressure warning is usually hidden in the instrument cluster. If a tire is losing pressure, a yellow exclamation mark inside a circle will immediately pop up on the LCD screen behind the steering wheel, accompanied by an exclamation icon. To check the specific status, you need to press the CAR button below the center console, rotate the knob to select the 'Vehicle' menu, and navigate to 'Maintenance and Inspection' to find the tire pressure monitoring. However, unlike higher-end models, it doesn't display specific tire pressure values, only indicating which tire is abnormal. Before every highway trip, I make it a habit to check this menu—only when all four tires show green do I feel at ease. After all, the indirect monitoring system relies on wheel speed sensors to calculate tire pressure, which isn't very intuitive. It's best to manually check with a tire pressure gauge every month.
