2018 Toyota Safety Sense - Lane Departure Alert

A camera on your windshield may help you avoid the consequences of unintended lane departure by alerting you when it senses that you’ve veered from your lane. Under certain circumstances, Lane Departure Alert (LDA) is designed to detect lane departure on roads with clear markings. LDA only activates when you’re traveling at a speed of 32 mph or faster. When you hear and see the alert, after carefully checking the road around you, you should safely direct your vehicle back to the center of your lane.
