Why can't the tire pressure be displayed on the CX-4?

Mazda CX-4's tire pressure monitoring system does not display the tire pressure; it only alerts when the tire pressure is abnormal. Below is an introduction to the tire pressure monitoring system: 1. Introduction: The tire pressure monitoring system, abbreviated as TPMS, stands for tire-pressure-monitoring-system. This technology can automatically monitor various conditions of the tires in real-time by recording the rotation speed of the tires or through electronic sensors installed inside the tires, providing effective safety assurance during driving. 2. Classification of Tire Pressure Monitoring Systems: Tire pressure monitoring systems can be divided into two types: one is the indirect tire pressure monitoring system, which determines tire abnormalities through differences in tire rotation speed; the other is the direct tire pressure monitoring system, which installs four tire pressure monitoring sensors inside the tires to automatically monitor the tire pressure and temperature in real-time, whether the vehicle is stationary or moving, and promptly alerts for high pressure, low pressure, or high temperature in the tires to prevent traffic accidents caused by tire failures, ensuring driving safety.
I've been driving my own Mazda CX4 for over a year now. When I first bought it, I was quite puzzled why I couldn't see the specific tire pressure values on the dashboard—only when the warning light came on did I realize there was an issue. After asking the salesperson, I understood that the base model of this car isn't equipped with a digital tire pressure display function. Instead, it uses an indirect tire pressure monitoring system, which only infers abnormalities based on wheel speed differences and doesn't display real-time pressure data. Only the higher-end models come with a direct display. I have to manually check the tire pressure with a gauge every month to ensure safety, especially since unstable tire pressure can cause skidding or loss of control at high speeds. I recommend new car owners carefully review the configuration sheet before purchasing or consider installing external sensors later to save money and hassle.
Friends who drive the CX4 often ask about tire pressure display issues. I think it's mainly due to configuration differences. Many entry-level versions deliberately omit real-time numerical displays to reduce costs, only retaining simple warning lights. You need to try enabling it through the in-car information screen menu, or the display anomaly might be caused by aging sensors losing signals—just replace the battery to fix it. Regular tire pressure maintenance is a must, otherwise it will accelerate tire wear, increase repair costs, and even affect braking distance, posing safety risks.
