How to Rematch the Tire Pressure Monitoring System on the Envision?

The method to rematch the tire pressure monitoring system on the Envision: Start the vehicle, locate and press the SET button on the left side of the multifunction steering wheel, then press the checkmark button on the right side of the multifunction steering wheel to confirm the operation. Once matched successfully, the tire pressure display on the central dashboard will return to normal. There are three commonly used tire pressure monitoring methods: Direct Tire Pressure Monitoring: The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. It transmits the pressure information from inside the tire to a central receiver module via a wireless transmitter, then displays the data for each tire's pressure. The system automatically alerts when the tire pressure is too low or 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, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. The indirect tire pressure warning system essentially relies on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of the indirect system, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data of the actual pressure in all four tires as the direct system does.
I've experienced three false tire pressure warnings in my three years of driving the Enclave. Recalibrating isn't actually difficult. With the car powered on but not started, find the 'Vehicle Information' on the center console screen, tap 'Tire Pressure', then select 'Relearn'. At this point, the horn will sound twice. Take the original small remote and hold it near the left front wheel's valve stem, pressing the button until the horn sounds again. Repeat this process in order for the right front, right rear, and left rear wheels. Finally, the center console will display 'Tire Pressure Relearn Complete'. Remember to do this when the car is cold - mornings in summer are ideal. After recalibration, drive about 2 kilometers and the tire pressure display will return to normal. This saves you 200 yuan compared to going to the 4S shop.
After the last tire repair, the mechanic forgot to match the sensors for me, but I figured it out myself. First, start the engine and then turn it off, turn the key to the ON position, and hold the tire pressure reset button near the driver's left foot for 5 seconds. After hearing two 'beeps', start deflating the left front tire until the horn sounds, then stop, refill the tire pressure, and move to the right front tire. Repeat this for all four wheels, and the yellow warning light on the dashboard will automatically turn off. Be careful not to deflate too quickly; it's more accurate to use a tire pressure gauge while deflating. This method is suitable for older models without a remote control.
