How to reset the tire pressure warning on Volvo S90?

Volvo S90 tire pressure warning reset steps: First, turn on the ignition switch, then when the TPMS indicator light is on, press the TPMS "SET" button for 1-2 seconds; after the TPMS indicator light goes off, release the "SET" button. What to do if the tire pressure is insufficient: If no damage is visible on the car's tires, simply inflate them to the normal tire pressure and reset the tire pressure system. If inspection reveals a puncture in the car's tire, drive to a repair shop promptly to have the tire patched before reinflating it. If the tire pressure warning reappears some time after inflation but there is no puncture, it may be due to air leakage caused by a deformed wheel rim. It is recommended to check the wheel rim and replace it if necessary. The working principle of the tire pressure monitoring system is: It uses pressure sensors installed inside the tires to measure the tire pressure and wireless transmitters to send the pressure information from inside the tire to the central receiver module.
I remember encountering a tire pressure warning when driving my Volvo S90 before, which was triggered after a long trip. Actually, resetting it was quite simple. First, ensure all tire pressures are normal—it's usually recommended to check when the tires are cold, with each tire inflated to around 2.5 bar (the standard value can be found on the label on the door frame). Then, sit in the driver's seat and start the car; you don't need to drive to perform the reset. On the central control screen, open the main menu, navigate to "Vehicle Settings," and select "Tire Pressure Monitoring." Here, the warning status will be displayed. Press the "Reset" or "Confirm" button, and the system will automatically reset the alarm after a short wait, turning off the warning light on the dashboard. After resetting, it's best to take a short drive to test if the system has returned to normal and avoid false alarms. I usually check the tire pressure every two weeks, as temperature changes in summer and winter can lead to more false alarms. Incorrect tire pressure not only triggers frequent warnings but also affects fuel efficiency and tire lifespan. Maintaining the right pressure can improve fuel efficiency by about 10% and enhance safety. I've used this method several times, and it always works.
