Those fluids should be changed every 15,000 miles if the majority of your driving involves towing, using a car top carrier or heavy loads. It is not required for normal operating conditions but may be recommended by your dealer. See your maintenance guide for details. ![Rav4 maintenance](https://global.discourse-cdn.com/cartalk/original/3X/f/1/f18d1361eab492be552ff68baab7ef79c63a407c.png)
