First, adjust the tire pressure to the standard value. Press and hold the middle button on the display to enter the learning mode, and the learning icon will flash. Press the left button to make the left front wheel icon flash, and install a new sensor on the left front wheel. Then press the right button to switch to the right front wheel, and install a new sensor on the right front wheel. After setting up all four sensors separately, press the middle button twice to return to the display's main page.
I just dealt with a tire pressure warning issue last month, and the reset process is actually quite simple. Park the car on level ground and turn off the engine, then locate the small button with an exclamation mark (the tire pressure reset button) below the left side of the steering wheel. Hold it until the dashboard indicator flashes three times and goes off, then start the vehicle and drive slowly for a few minutes to allow the system to self-calibrate. Remember to ensure all four tires are inflated to the standard pressure before resetting, otherwise the system may trigger false alarms during highway driving. If you can't find the button, check the owner's manual as locations vary by brand—for example, Volkswagen places it in the glove compartment while Toyota requires operation through the steering wheel menu.
As a seasoned mechanic who works on cars every day, I recommend checking if the tire pressure gauge readings are consistent before resetting the tire pressure. The operation is simple: after straightening the steering wheel and turning off the engine, locate the reset button near the driver's knee position, press and hold it for 5 seconds, then release when the tire pressure light on the dashboard flashes. Here's the key point! You must let the car idle in place for two minutes to allow the system to automatically save the new data for it to take effect. Some newer models require connecting to a diagnostic computer and entering an authorization code to reset, such as BMW's ISTA program which requires professional equipment. After resetting, take a highway drive to confirm the effect, as any deviation may cause the ABS linkage system to fail.
