How to Reset the Normal Tire Pressure Monitoring Light?
3 Answers
Here are the methods to reset the tire pressure monitoring light: Drive Slowly: Find a safe place to park, then turn off the engine. Wait for 1 to 2 minutes before restarting the vehicle. After the vehicle stabilizes, check the tire pressure value displayed on the dashboard. Self-Inflation: If you have a portable inflation device, you can adjust the tire pressure on the spot. Monitor the Tire Pressure Light: While inflating or deflating the tires, observe the tire pressure light on the dashboard. Stop inflating once the light turns off. If overinflated, release excess air (preferably with assistance). Manual Reset: If the tire pressure light remains on after adjustment, a manual reset is required. Locate the settings button on the car's central console, usually labeled as the SET key, to perform a tire pressure reset.
I encountered this issue right after I started driving—the tire pressure light came on, but the actual tire pressure was fine. It might be a false alarm from the sensor or a calibration issue. I usually drive slowly for a few minutes first to let the system refresh itself. If the light stays on, I manually reset it: find the tire pressure settings button on the center console, hold it for five seconds until the light flashes, then release and wait for it to recheck. This happens especially often in summer heat due to tire expansion and contraction affecting the readings. Low battery in the sensor can also cause false alarms, so I check the battery status periodically.
From a technical perspective, this situation is mostly caused by a temporary glitch in the tire pressure monitoring module. The sensor signal may be interfered with, or the system hasn't updated the data after recent tire inflation. Based on my experience: first try turning off and restarting the vehicle. If that doesn't work, locate the tire pressure calibration option in the vehicle menu for a reset – button positions vary by model, with German cars usually placing it near the gearshift, while Japanese models often have it in the central control screen settings. Remember to drive at 60 km/h for two to three kilometers after resetting to allow the sensors to recollect data. During winter snow driving, metal components may cause signal interference – don't worry too much if the light comes on then.
