What Is Toyota's Lane Tracing Assist (LTA)?
You may have been scrolling through the available features within your vehicle’s Multi-Informational Display (MID) and noticed a feature called Lane Tracing Assist. This feature works with other safety features within the Toyota Safety Sense suite.
LTA uses lane markers and preceding vehicles to help center a car in its lane. With DRCC on, the Emergency Driving Stop System can bring a vehicle to a stop. There is much more to it than this simple explainer, so let’s dive in to see how this feature works and how to use it.

How Does the Toyota Lane Tracing Assist Work?
Toyota Lane Tracing Assist’s main feature is keeping the vehicle centered in its lane and spatially apart from the preceding vehicle. LTA works with the Dynamic Radar Cruise Control to set a predetermined distance between you and the vehicle in front of you. The DRCC preset has three or four distance settings depending on the vehicle and whether it is the DRCC with a Full-Speed Range or without.
The high-resolution, wide-angle front-facing camera system can detect lane markers and use lines on the road to help keep the vehicle centered in its lane. Toyota took this system a step further by enhancing the lane recognition features by detecting particular three-dimensional objects like guardrails to help define a lane better.
This system can also help when passing. Suppose a vehicle is in an adjacent lane. In that case, the system can make minor steering adjustments in the driving path when passing to give more space between vehicles.
Toyota LTA has one more trick up its sleeve: the Emergency Driving Stop System.
The Emergency Driving Stop System (EDSS) is a Lane Tracing Assist (LTA) component. EDSS checks the driver’s actions on the steering wheel and pedals to determine if the driver is unresponsive or not paying attention. The system can stop the car if the driver fails to respond to alerts asking them to take control.
How to use the Lane Tracing Assist
Here is a step-by-step guide to turning on LTA
- First, make sure you have the Dynamic Radar Cruise Control system on. To do this, it may vary based on the vehicle. Look for the Cruise Control button with a speedometer icon with the word “mode” underneath it.
- Pressing this button will toggle between Cruise Control Mode and Adaptive Cruise Control Mode.
- Ensure that when pressing the Cruise Control Button, you are in Adaptive Cruise Mode, which will display a car icon with a speedometer icon underneath.
- Drive above 20 miles per hour, then set your speed using the Cruise Control set button.
- This button will have a car icon and a speedometer icon underneath.
- Once activated, this icon on the Multi-Informational Display changes from white to green.
- To activate the LTA, look for a button with a car icon between the lane markers; this button toggles the LTA on and off.
- Once activated, the LTA icon on the Multi-Informational Display also changes from white to green.
Benefits of Toyota Lane Tracing Assist
Enhanced Safety: LTA helps to keep the vehicle centered within its lane, reducing the risk of lane departure accidents.
Driver Convenience: The system makes driving easier on highways and long trips by reducing the need for constant minor steering adjustments.
Reduced Driver Fatigue: By assisting with steering, the system can help decrease the physical and mental fatigue that drivers may experience during extended periods behind the wheel.
Improved Focus: With LTA managing some aspects of steering, drivers can focus better on the road and other driving elements, like checking mirrors or keeping an eye on other vehicles.
Increased Peace of Mind: Knowing that the system monitors the lane position can give drivers an added sense of security, especially in challenging driving conditions like heavy traffic or bad weather.
Compatibility with Adaptive Cruise Control: LTA often works with Adaptive Cruise Control to manage speed and steering, offering a more comprehensive assisted driving experience. Plus, it is compatible with other Toyota Safety Sense features like Proactive Driving Assist. PDA can provide gentle braking when driving into curves or steering to help support other driving tasks.
