What is the meaning of the LTA Lane Tracing Assist

Lane Tracing Assist (LTA) assists your vehicle in staying in its lane by monitoring road markers. This reduces the likelihood of an accident and alleviates part of the pressure on you, the driver. This Toyota Safety Sense feature works in tandem with Adaptive Cruise Control to make your drives in crowded traffic less stressful.

WARNING

Do not rely solely on the LTA system. The LTA system does not automatically drive the vehicle or reduce the amount of attention that must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving safely by paying careful attention to the surrounding conditions and operating the steering wheel to correct the path of the vehicle. Also, the driver must take breaks when he or she is tired, like after driving for a long time.
Failure to perform appropriate driving operations and pay careful attention may lead to an accident, resulting in death or serious injury.
When not using the LTA system, use the LTA.
