This SAE Standard specifies symbols (i.e. conventional signs) for use on controls, indicators, and tell-tales applying to passenger cars, light and heavy commercial vehicles, and buses, to ensure identification and facilitate use. It also indicates the colors of possible optical tell-tales, which inform the driver of either correct operation or malfunctioning of the related devices.
This revision incorporates symbols from ISO 2575 that were not included in the prior version of SAE J2402. Symbols F.27 and Z.01A, which are regulated symbols in the USA, are included in this document, but are not in ISO 2575. Symbols K.07B (child seat) and K.22 (CPOD) are in ISO 2575 but are not in this document.
