How to reset the tire pressure warning on the CS15?

[GriffinRose]

The method to reset the tire pressure warning on the CS15 is: 1. Press the square icon button on the left side of the steering wheel to switch to the tire pressure monitoring screen; 2. Press the triangle icon button to clear and reset. Taking the 2021 Changan CS15 as an example, its body dimensions are: length 4135mm, width 1740mm, height 1630mm, wheelbase 2520mm, fuel tank capacity 44l, and curb weight 1210kg. The 2021 Changan CS15 is equipped with a 1.5l naturally aspirated engine, with a maximum horsepower of 107ps, maximum power of 78.5kw, maximum torque of 145nm, and is paired with a 5-speed manual transmission.

I've been driving the Changan CS15 for two years, and encountering tire pressure warnings is quite common. When the tire pressure warning light comes on, the most straightforward method is to first check if any of the four tires have obvious leaks or punctures. You can use a tire pressure gauge to measure the tire pressure and adjust it according to the standard values posted on the door frame. If the tire pressure is normal but the light remains on, you'll need to manually reset it. I usually do this through the menu button on the left side of the steering wheel—press it to enter the vehicle settings interface, scroll down to the tire pressure monitoring option, and hold the OK button for a few seconds to clear it. The system will automatically confirm after driving a few hundred meters. Remember, you must ensure the tire pressure is normal before resetting, otherwise, driving on the highway can be dangerous. Some owners might experience unsuccessful resets, which could be due to lost sensor signals or power supply issues with the module. In such cases, I usually go directly to the 4S店 and have them reset it using a diagnostic computer—it only takes a few minutes. I also recommend regularly checking the tire pressure and not waiting for the warning light to take action.

Last time I took my friend's CS15 on a long trip, the tire pressure warning light suddenly came on, almost ruining the journey. I quickly pulled over and used the onboard tire pressure gauge to check, finding the right front tire pressure had dropped to 1.6. After finding a tire repair shop to reinflate it, I thought the warning light would turn off automatically, but it kept flashing. Later, I found the manual in the glove compartment in front of the passenger seat and followed the instructions to reset it: turn the ignition to the ON position without starting the engine, then press and hold the tire pressure reset button with an exclamation mark under the center console. Hold it until the tire pressure light on the dashboard flashes three times and goes off, which finally solved the problem. A reminder to new car owners: during seasonal changes between winter and summer, temperature differences can easily cause false tire pressure warnings. If you see the light on in the morning, don't panic—drive for a while to see if it goes away on its own. Make it a habit to check tire pressure monthly, as proper tire pressure ensures both safety and fuel efficiency.

Our car club often receives questions from CS15 owners about resetting the tire pressure warning. The actual operation is quite simple and can be done in three steps: First, measure the tire pressure and top it up if necessary. For models after 2019, you can directly operate it using the steering wheel buttons. Use your right thumb to scroll the wheel to the tire pressure icon, press OK to enter the reset interface, then hold for five seconds to complete the reset. For older models, look for the physical button on the left panel of the driver's side. Once, while helping a fellow owner, the reset failed, and it turned out the issue was modified rims without matching tire pressure sensors. If you encounter tricky problems, remember to connect to the OBD port to check the fault codes—it might be a dead sensor or a faulty controller. Usually, glance at the dashboard indicator lights at red lights; spotting issues early can prevent uneven tire wear from underinflation.

As a mechanic who frequently services domestic cars, there are basically two solutions for the CS15 tire pressure warning elimination issue. If it's caused by low tire pressure, the system will automatically reset after driving a few kilometers with properly inflated tires. However, if it's a false alarm from the system, manual reset is required, which is quite common in domestic cars. For newer models, you can turn off the engine, hold down the triangular arrow button on the left side of the steering wheel, then turn the key to power on without starting the engine. Release the button when you see the dashboard lights flash. For older models, find the vehicle status option in the settings on the central control screen. If the warning keeps recurring, there's an 80% chance the tire sensor is faulty, and replacing it costs just over a hundred yuan. Remember to drive for twenty minutes after resetting to let the system confirm the status. Don't park immediately after resetting, or the operation might be in vain.

Handling the CS15 tire pressure warning light yourself can actually save time and money. That time when the warning light came on during rain, I first used a portable air pump to inflate all tires to the standard 2.3 value, but the warning didn't clear. Then I tried holding down the tire pressure reset button under the front passenger seat for ten seconds—this is the hidden method for older models. When that didn't work, I tried the steering wheel operation: switching to vehicle settings with the mode button on the right side, entering the tire pressure menu, and confirming the reset. Finally, the light went off. I recommend beginners save a reset video on their phones to follow in emergencies. If you've modified tire sizes or installed additional tire pressure monitoring devices, it's best to visit a professional shop for program matching, as it might interfere with the factory system otherwise.
