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

[CorbinLee]

The method to reset the tire pressure warning on the Changan CS55 is: Press the square icon button on the left side of the steering wheel to switch to the tire pressure monitoring screen, then hold down the triangular icon button to clear the tire pressure warning. Taking the 2019 Changan CS55 as an example, its body structure is a five-door, five-seat SUV with dimensions of 4500mm in length, 1855mm in width, and 1690mm in height, a wheelbase of 2650mm, a fuel tank capacity of 58 liters, and a curb weight of 1460kg. The 2019 Changan CS55 is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 156PS, a maximum power of 115kW, a maximum torque of 225Nm, and is paired with a 6-speed manual transmission.

I remember last time the tire pressure warning light on my Changan CS55 came on, and I fixed it myself. Usually, you first check if the pressure in all four tires meets the standard, typically around 2.2-2.5 bar. If everything is normal, start the vehicle but don't drive off immediately. Find the menu button on the dashboard, switch to the settings interface, and there's a tire pressure calibration option—hold it down for more than three seconds. If you can't locate the button, refer to the illustrations in Chapter 8 of the owner's manual. After resetting, drive a few hundred meters, and the system will automatically detect and the warning light will turn off. Be extra cautious about tire pressure discrepancies on rainy days—I once had a false alarm due to cooler tires in the rain. Developing a habit of checking tire pressure monthly can save a lot of trouble. For example, overinflated tires wear out faster in the middle, while underinflated tires increase fuel consumption and the risk of a blowout. Keeping a compact digital tire pressure gauge in the glove box is quite handy.

I've encountered this issue several times and now it's become routine. Resetting the tire pressure warning on the Changan CS55 doesn't require wasting money at a 4S shop. First, park the car and start the engine, then use the button panel on the right side of the steering wheel to scroll up and down to find the vehicle settings menu. The reset option for the tire pressure monitoring system inside requires confirmation twice. The key point is to ensure there's genuinely no air leak in the tires. Once, I forgot to check the right rear tire that had a nail in it, and after resetting, the light came back on within 20 meters of driving. If you don't have an air pump, remember to adjust the tire pressure when the tires are cold when filling up at a gas station, as the pressure in heated tires can be falsely high by about 0.3 bar. If the reset fails, it might be because the sensor battery is dead, a common issue after three or four years of driving this car. Replacing it with an original sensor only costs around a hundred yuan.

Handling this is actually quite simple: First, get out of the car and walk around to kick the tires to confirm there's no obvious loss of air. The standard tire pressure is listed on the back of the fuel filler cap. Return to the driver's seat, start the engine, and switch the combination control on the lower left side of the steering wheel to the trip computer settings page. Select the tire pressure reset and confirm. In winter, pay special attention to thermal expansion and contraction; when temperatures drop below freezing, tire pressure can decrease by about 0.2 bar, which can easily trigger a false alarm light. If the reset doesn't work, consider the possibility of a wheel speed sensor issue, especially since they can get damaged when going over speed bumps. When washing your car, avoid using a high-pressure water jet directly on the air valves, as aged rubber valves can lead to slow leaks and trigger alarms. For cars older than three years, it's advisable to have a mechanic check the sensor battery during regular maintenance.

As a seasoned driver, I must remind you of a few key details. Never attempt to reset the tire pressure warning while driving—always stop and shift to Park (P) first. The Changan CS55 has a tire pressure reset option in the instrument cluster's trip computer, but base models lack this feature and require an additional module. High summer temperatures trigger more frequent alerts, as tire pressure rises by 0.07 bar per 10°C increase. After patching a tire, drive at least 2 km for the system to update—resetting too early will fail. Persistent warnings may indicate slow leaks from rim deformation, a common issue after hitting potholes. Vehicles with modified wheel sizes need system reprogramming, or warnings will persist indefinitely. Developing a habit of checking tire pressure during refueling is more effective than any troubleshooting trick.

I take tire maintenance very seriously, as improper handling of tire pressure warnings can affect wheel alignment accuracy. The basic steps to clear the alarm are: after confirming the tire pressure meets standards, operate the steering wheel toggle switch to enter system settings when the ignition is in the second position, select TPMS calibration, and hold for 5 seconds. Note that the parking surface must be level, as the system may misjudge on inclined surfaces. There might be a delay after operating in rainy conditions—don’t rush to repeat the setup as the sensors react slower when wet. Owners who have modified their tires should check the compatibility of the new tires; a tread depth difference exceeding 1.5mm will trigger the alarm. Sensors in long-term parked vehicles may enter sleep mode but will reactivate after driving a few kilometers. Spare tires without sensors can be ignored, but for tires older than five years, a comprehensive sensor check is recommended to avoid false alarms.
