How to reset the tire pressure warning light on Changan CS55?

Method to reset the tire pressure warning light on Changan CS55: There is a circular operation button in the middle of the right side of the Changan CS55 cockpit. First, turn on the ignition switch without starting the car. Then press the operation button, and options will appear on the central display screen. Select the "Vehicle Information" option and click OK, then the reset items will appear. Find the tire pressure reset and follow the on-screen system prompts to reset the tire pressure settings. Below is some related information: 1. When the tire pressure warning light comes on, it indicates that the pressure in one or more tires is too low or too high. When the vehicle's tire pressure monitoring system detects an abnormality, a warning message will appear on the display screen, and the tire pressure warning light will illuminate. 2. If the tire pressure warning light comes on while driving on the highway, do not panic. Immediately reduce your speed and avoid sharp steering and sudden braking, then check the tires. If you find that the tire pressure is significantly low, you can drive to the nearest service area for inspection and repair. 3. Generally, the standard tire pressure for small cars is between 2.4-2.5 bar. Both overinflation and underinflation can affect tire performance. Overinflation can affect braking power, while underinflation can cause rapid wear on the tire sidewalls. Continued driving with low pressure can lead to sidewall rupture and even tire blowouts. Always refer to the car's maintenance manual for the standard tire pressure.
I also encountered the tire pressure warning light issue when driving my Changan CS55 last time, and managed to solve it myself. First, confirm the tire pressure is normal—the recommended value is usually found on the door frame or in the manual, typically between 2.2-2.5 bar. If it’s low, just add some air. If the tire pressure is fine, locate the TPMS reset button in the car, usually near the center console or under the steering wheel when the engine is off, and hold it until the light turns off. If that doesn’t work, you might need to manually reset it through the vehicle’s system menu after starting the car. The process is quick and doesn’t take much time. Prevention is key—I check my tire pressure weekly to avoid issues like small stones puncturing the tire or pressure fluctuations due to temperature changes. Ignoring it can lead to persistent warning lights and even affect handling and fuel efficiency, so regular checks are essential. If you still can’t fix it, visit a 4S shop and let the technicians diagnose any sensor issues with professional tools—they’ll have it fixed in no time.
