How to Reset the Changan Tire Pressure Monitoring Light?
3 Answers
Firmly press the vehicle's brake pedal to prepare for turning on the power. Press the vehicle's one-touch start button. The dashboard lights up, indicating the power is on. Inflate all four tires to the standard pressure. Press and hold the tire pressure warning light reset button for 3 seconds.
When the tire pressure monitoring light comes on in my Changan car, I immediately find a safe spot to pull over and turn off the engine. I take out the tire pressure gauge from the car and check all the tires. The standard pressure is usually between 2.2 and 2.5 bar. If any tire is low, I quickly inflate it to the correct value. Once everything is normal, I start the engine and locate the reset button near the steering wheel, holding it down for a few seconds. The light usually goes off. I remember the last time this happened in my Changan, I found a slight leak in the left front tire. After fixing it and resetting, everything was fine. The tire pressure light is a safety warning that helps prevent blowout risks, so I make it a habit to check my tires weekly, including pressure and tread wear. If the light stays on and doesn’t go off, don’t hesitate—visit a 4S shop or a professional repair center to check if the sensor is faulty.
The tire pressure warning light is indeed annoying. I also encountered it frequently when I first bought my Changan car. The simplest solution is to park the car, use a tire pressure gauge to check each wheel's pressure (the standard value is around 2.3 bar), and inflate if necessary. After ensuring proper pressure, start the engine and hold the reset button for 5-10 seconds. Driving for a while to let it self-calibrate works even better. I always carry a portable air pump with me - this trick works wonders. Most light activations are minor issues, but if it keeps recurring or resetting doesn't work, there might be a slow leak or system malfunction requiring technician inspection. By the way, regular tire pressure checks can also save fuel and reduce wear - multiple benefits in one go.
