What to Do When the Car Shows Low Tire Pressure?
2 Answers
There are generally three methods to eliminate the low tire pressure warning light: The first is to check and confirm whether the tire pressure is normal. If there is a problem, adjust it to the standard tire pressure, then drive a few kilometers on the road. Usually, the computer will automatically correct and reset at this point. The second method, when confirming that the tire pressure is normal, is to go to an auto service shop to check the tire pressure sensor and clear the fault code. The third method requires finding the setup button on the central console for manual reset, usually by pressing the SET button. Tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep," then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the original data, and finally, the fault light on the dashboard will go out, completing the tire pressure reset.
Last time the tire pressure light came on in my old Accord, I immediately pulled over to check. Low tire pressure is most commonly caused by a nail puncture and air leakage or temperature changes—tire pressure naturally drops a bit in cold weather. If you ignore it, the car won’t drive smoothly, fuel consumption will increase, and the risk of a blowout becomes much higher. I always carry a portable tire pressure gauge with me; just plug it into the valve stem to get an instant reading. The recommended pressure is usually labeled on the door frame or fuel cap. If you find the pressure is indeed low, head to the nearest gas station to inflate it to the proper level. If there’s a severe leak or obvious crack, don’t risk driving—call a tow truck and take it straight to a repair shop for inspection and patching. It’s best to check your tire pressure monthly and keep it within the 25-35 psi range for safety. In emergencies, always prioritize safety—never delay.
