What Does Toyota’s LTA (Lane Tracing Assist) Do?

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.


Before using LTA (Lane Tracing Assist)  system

  • 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.

Situations unsuitable for the LTA  (Lane Tracing Assist) system

In the following situations, use the LTA switch to turn the system off. Failure to do so may lead to an accident resulting in death or serious injury.

  • A vehicle is driven on a road surface that is slippery due to rainy weather, fallen snow, freezing weather, etc.
  • A vehicle is driven on a snow-covered road.
  • Due to rain, snow, fog, dust, etc., white (yellow) lines are difficult to see.
  • A vehicle is driven in a temporary lane or restricted lane due to construction work.
  • A vehicle is driven in a construction zone.
  • A spare tire, tire chains, etc. are equipped.
  • When the tires have been excessively worn or when the tire inflation pressure is low,
  • When tires of a size other than specified are installed,
  • Vehicles are driven in traffic lanes other than highways and freeways.
  • When your vehicle is towing a trailer or during emergency towing.

Preventing LTA system malfunctions and operations performed by mistake

  • Do not modify the headlights or place stickers, etc., on the surface of the lights.
  • Do not modify the suspension, etc. If the suspension, etc., needs to be replaced, contact your Toyota dealer.
  • Do not install or place anything on the hood or grille. Also, do not install a grille guard (bull bars, kangaroo bars, etc.).
  • If your windshield needs repairs, contact your Toyota dealer.
