Alright. So there are two different types of TPMS. One checks the rotation of the tires in relation to each other. The other actually reads the pressure in each tire. The older CX-9s use the tire rotation method. Yours should be using the actual tire pressure. The reason your older one had the button is to correct the vehicle when you have fully inflated and fine tires but the vehicle thinks you don’t. This could be from one tire being more worn than the others or different types of tires with different levels of grip. With a TPMS that actually reads pressure, you get the light until you are inflated to the correct pressure. There’s no override because it is more accurate and actually means you have an issue if it is lit.
