How to reset the tire pressure light on the new Wuling Hongguang?

After the tire pressure indicator light comes on, first check the tire pressure monitoring function on the car's navigation screen to identify any abnormal wheels. Once you confirm there is an issue with a wheel, you must check whether the tire pressure is too high or too low. If the tire pressure is too high and triggers an alarm, you can slightly release some air to bring the tire pressure back to the safe value. There is a tire pressure reset button—press it to confirm and reset. If the display shows the tire pressure is too low, you need to reset it and then drive the car for a while. The tire pressure warning will then disappear, resolving the issue.
I encountered a tire pressure warning light issue right after getting my new Wuling Hongguang, but figured it out myself. First, ensure all four tires are inflated to the standard pressure (marked on the door frame). If the pressure is correct but the light remains on, try this via the infotainment screen: After starting the vehicle, tap 'Vehicle Settings' on the homepage, locate the 'Tire Pressure Monitoring' option, then select and confirm the reset. For some higher-trim models, you may need to long-press the menu button on the left side of the steering wheel to access the engineering mode. After resetting, drive 2-3 km for automatic system calibration. If the light persists, it might indicate sensor failure—visit a 4S shop to read fault codes. Avoid spraying high-pressure water directly at the wheel hubs during car washes, as soaked sensors are prone to damage.
Having repaired hundreds of Wuling Hongguang vehicles, I've learned that resetting the tire pressure warning light on the new model requires precise timing. It must be done in a 'cold tire' state—meaning the vehicle has been parked for over three hours to allow tire temperatures to return to ambient. Turn on the ignition without starting the engine, then use the center console knob to navigate to the 'Tire Pressure Reset' option in system settings. Follow the prompt to press the confirm button for five seconds. A common mistake is attempting this while driving, which will trigger an immediate system error. A confirmation chime will sound upon successful reset. As a reminder: the spare tire lacks sensors, so ignore its pressure readings. If you've modified the wheels, ensure the original sensors are transplanted by your mechanic—otherwise the warning light will stay illuminated. During routine maintenance, have technicians check sensor battery levels with professional equipment; they typically last 5-6 years.
