The Toyota RAV4 is a popular compact SUV known for its reliability, comfort, and advanced driving technology. One of the standout features of the RAV4 is its Lane Departure Alert with Steering Assist, designed to help drivers maintain their lane on the freeway and suburban roads. However, like any technology, it may sometimes encounter issues. If you’re experiencing problems with your Toyota RAV4’s lane assist system, this guide will help you understand the possible causes and solutions to get your vehicle back on track.
Understanding the Lane Assist System
Before delving into troubleshooting steps, it’s crucial to understand how the lane assist technology in your Toyota RAV4 works.
