How to reset the tire pressure light on a 2009 Lavida?

Tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top, four small spikes at the bottom, and an exclamation mark inside. The illumination of the tire pressure monitoring indicator indicates abnormal tire pressure. Abnormal tire pressure is generally caused by the following reasons: Abnormal tire pressure: Usually, an alarm will sound if the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to light up. In this case, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged during driving, it will also cause the tire pressure warning light to illuminate. For sensor damage issues, only a replacement with a new part is possible.
Had a persistent tire pressure light issue with my 2009 Lavida, tried fixing it myself multiple times. This usually stems from uneven tire pressure or sensor malfunction. First step is checking all tires' pressure (including spare), inflate to the manual-recommended 220-240 kPa when cold. If normal, hold the dashboard reset button for 20+ seconds. If that fails, likely sensor battery depletion - decade-old cars often need replacements (300-500 RMB per sensor). Also consider post-inflation calibration: drive slowly for system to recalibrate. Faulty sensors are common; workshops diagnose quickly. Safety first - driving with warning lights affects stability. Address it early to save cost and hassle.
The root cause of the Lavida's tire pressure light not turning off lies in an electronic system malfunction. The TPMS indirectly detects via wheel speed sensors, and the light staying on may indicate a software bug or hardware failure. First, I check all tire pressures meet standards, then press and hold the reset button. If ineffective, an OBD tool is needed to read fault codes. Sensor batteries typically last 7 years - 2009 models are prone to power depletion, requiring professional matching after replacement. Sometimes ABS module interference necessitates ECU software updates. DIY repairs are inconvenient; leaving diagnosis to technicians ensures precision and efficiency. Regular maintenance should monitor tire wear to avoid costly sensor damage. Prompt resolution ensures handling safety - delays only worsen the issue.
The tire pressure warning light won't turn off, which is crucial for driving safety. Low tire pressure increases the risk of a blowout and should not be ignored. I immediately checked that all tire pressures were consistent and adjusted to the cold tire value specified in the manual. If the light remains on, the sensor may be faulty or the system may need recalibration—try driving slowly in circles a few times. If that doesn't work, visit a professional shop for inspection, sensor replacement, or software updates. Prioritize safe driving and don't risk driving with potential hazards.
