How to Reset the Tire Pressure Warning Light on a Sagitar?

The method to reset the tire pressure warning light on a Sagitar: First, turn on the ignition, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. Tire pressure monitoring automatically checks the tire pressure in real-time while driving and alerts the driver to leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring systems: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is then transmitted wirelessly from inside the tire to a central receiver module, which displays the tire pressure data for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between the tires, the system monitors the tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): This system combines the advantages of the two systems mentioned above. It is equipped with direct sensors in two diagonally opposite tires and an indirect system for all four wheels. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect low pressure in multiple tires simultaneously. However, it still cannot provide real-time pressure data for all four tires like a direct system.
After driving my Sagitar for several years, I've encountered the tire pressure warning light multiple times. Initially, I panicked, but later learned it's usually due to uneven tire pressure or sensor false alarms. First, check all four tires' pressure—the door frame label shows standard values, like 2.3Bar for front tires and 2.2Bar for rear tires. If low, use a pump to refill. After refilling, get in the car, turn the key to the ON position (second click) without starting the engine, then use the right-side steering wheel buttons to navigate the dashboard, enter the CAR menu, select the tire pressure monitoring option, and press the reset button. The system will then recalibrate to the current pressure, and the light should turn off after driving a few hundred meters. If it doesn’t, there might be a slow leak or the sensor battery is dead—time for a shop visit. I check my tire pressure monthly; it’s hassle-free and prevents blowout risks. Don’t just reset without adjusting pressure, or the light will keep coming back, compromising safety.
