Because the model usually represents the manufacturer in English, the first number represents the model, the next two numbers represent the displacement, the last number is the identification code, and the last English is the configuration. For example, Camry's 240G is GTM 7240G(GTM- GAC Toyota, 7 cars, 24-2.4L, 0- identification code, for example, there are two 2.4L engines, so this is the difference, and G stands for G-class configuration problem).
So if your vehicle model is ST 18, there should be a problem.
There should be a nameplate on the B-pillar on the right side of your car with the model number on it.
