How to Check the Tire Pressure Monitoring on Trumpchi GM8?
2 Answers
The tire pressure monitoring switch for the Trumpchi GM8 is located on the steering wheel. Press the page-turning button to display the tire pressure information. The tire pressure monitoring function can monitor the tire pressure and temperature of each tire in real-time and will alert the driver promptly when any abnormalities are detected, allowing timely action to prevent accidents. Tire Pressure Reset Method: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the tire pressure reset is complete. There are three commonly used 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. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight 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 essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): This system combines the advantages of both the direct and indirect systems. It is equipped with direct sensors in two diagonally opposite tires and an indirect system for all four wheels. Compared to a fully direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as accurately as a direct system.
As an owner of the Trumpchi GM8, I find the tire pressure monitoring system very practical and easy to use. After starting the car, there are usually navigation buttons on the left side of the steering wheel. Pressing them a few times will switch to the tire pressure display interface on the dashboard, which provides real-time pressure readings for each tire. For example, in cold conditions, a pressure between 2.3-2.5 bar is normal. I make it a habit to quickly check before driving to ensure there are no abnormal values below 2.0 or above 3.0 bar. If the tire pressure is low, it will automatically trigger an alarm, but I still prefer manual checks for extra peace of mind. During my daily city commutes, I verify the tire pressure every week to avoid the risk of blowouts, improve fuel efficiency, and ensure safe driving. I recommend referring to the car’s manual or asking a technician during 4S store maintenance for calibration methods, as tires are the lifeline of a vehicle.
