How does it work?
When driving at speeds above approximately 50 km/h on relatively straight roadways, Toyota’s Lane Departure Alert will attempt to determine your vehicle’s position within its lane using an in-vehicle camera designed to detect visible white-and-yellow lane markings.
If the system determines that your vehicle is starting to unintentionally deviate from its lane, a buzzer will sound and, depending on the direction you’re drifting, one of the lane markings on your dashboard’s multi-information display will begin to flash.
Together, these warnings tell you to check the surrounding road situation and carefully operate the steering wheel to move your vehicle back to the centre of your lane. (These alerts will not activate when you operate your turn signals to intentionally cross lane markings.)
If your vehicle includes Steering Assist (available in some TSS-P equipped vehicles), the system may provide small corrective steering inputs for a short period of time to help keep the vehicle in its lane. If your vehicle is equipped with this feature, you can also adjust alert sensitivity settings and turn the Steering Assist function on and off.
