To permanently disable the auto start-stop function in RAV4, simply press the button to turn it off. Below is an introduction about RAV4: 1. Overview: The Toyota RAV4 is the base model in Toyota's compact multi-purpose off-road vehicle family. Its name comes from the abbreviation of "Recreational Active Vehicle with 4-wheel drive," meaning "a four-wheel-drive recreational and sport vehicle." 2. Model: It features a completely new exterior and interior design, with the overall styling further evolving towards an urban SUV, while the off-road characteristics gradually fade from this model. 3. Positioning: The RAV4 combines high quality and performance with driving comfort and excellent off-road capability, allowing it to adapt seamlessly to both ON ROAD and OFF ROAD conditions, meeting the needs of diverse lifestyles. Therefore, it is a high-performance urban SUV that "adapts effortlessly."
I've tried the auto start-stop function on the RAV4, to be honest, it's quite troublesome to permanently disable it. The factory design is to automatically activate it every time the car starts, and the system doesn't provide an official disable option. Some people suggest unplugging the battery sensor harness to bypass it, but this will trigger the warning light and may cause the battery to fail prematurely. My experience is that the most reliable method is to press the start-stop switch on the center console every time you get in the car—it's the button with the letter 'A'—just make it a habit. If you drive this car long-term, you can also install a third-party start-stop disabler, which plugs into the OBD port to simulate the button signal, but modifications might affect the warranty. If you really can't be bothered, just let it work; it actually has minimal impact on fuel consumption.
