How to reset the tire pressure monitoring on the Southeast DX3?
2 Answers
Southeast DX3 tire pressure monitoring reset method: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button. After hearing a "beep" sound, release the button. The tire pressure monitoring system will store the current normal tire pressure data and automatically clear the previous data. Finally, the warning light on the dashboard will turn off, indicating the tire pressure reset is complete. Solutions for insufficient tire pressure: If no visible damage is found, simply inflate the tire to the normal pressure and reset the tire pressure system. If a puncture is detected during inspection, drive to a tire repair shop promptly to have the tire patched and then reinflate it. If the low tire pressure warning reappears after inflation without any punctures, it may be due to air leakage caused by a deformed wheel rim. It is recommended to inspect the wheel rim and replace it if necessary. Hazards of low tire pressure: Increased friction coefficient with the road surface leads to higher fuel consumption. It also causes the steering wheel to feel heavy and may result in vehicle drift, posing risks to driving safety.
I'm a car enthusiast who frequently works on vehicles, and I've dealt with the DX3's tire pressure warning light before. First, park the car and use a tire pressure gauge to check all tire pressures when cold, ensuring they're within the normal range of 28-35 PSI and there are no leaks. If the tire pressure is correct, there's usually a small button labeled TPMS on the left side of the steering wheel or the center console—press and hold it for 5-10 seconds until the warning light turns off. This should be done with the engine running for safety. After resetting, drive for a while to see if the system stabilizes. If not, it might be due to aging sensors or the system needing a reset after tire rotation. While driving, pay attention to how tire temperature affects readings to reduce false alarms. I believe eliminating the warning isn't about disabling the system but letting it relearn the current pressure values. If there's a real issue, it's best to visit a professional shop for diagnosis.
