LTA (Lane Tracing Assist)

LTA functions
When driving on a road with clear lane lines with the dynamic radar cruise control operating, lane lines and pre-ceding and surrounding vehicles are detected using the front camera and radar sensor, and the steering wheel is operated to maintain the vehicle’s lane position.

• Use this function only on highways and expressways.

• If the dynamic radar cruise control is not operating, the function will not operate.

• In situations where the lane lines are difficult to see or are not visible, such as when in a traffic jam, support will be provided using the path of preceding and surrounding vehicles.

• If the system determines that the steering wheel has not been operated for a certain amount of time or the steering wheel is not being firmly gripped, the driver will be alerted and this function will be temporarily canceled.

• If the steering wheel is firmly gripped, the function will begin operating again.

• When the function is operating, if the vehicle is likely to depart from its lane, the driver will be alerted via a display and buzzer.

When the buzzer sounds, check the area around the vehicle and carefully operate the steering wheel to move the vehicle back to the center of the lane.

WARNING

• Before using the LTA system
• Do not overly rely on the LTA system. The LTA system is not a system that provides automated assistance in driving and it is not a system that reduces the amount of attention necessary for safe driving. The driver is solely responsible for paying attention to their surroundings and operating the steering wheel as necessary to ensure safety. Also, the driver is responsible for taking adequate breaks when fatigued, such as when driving for a long time.
• Failure to perform appropriate driving operations and pay careful attention may lead to an accident.
• When not using the LTA system, turn it off using the LTA switch.

Operating conditions of function

• This function is operable when all of the following conditions are met:
• The LTA system detects lane lines or the path of preceding or surrounding vehicles.
• The dynamic radar cruise control is operating.
• The lane width is approximately 10 to 13 ft. (3 to 4 m).
• The turn signal lever is not being operated.
• The vehicle is not being driven around a sharp curve.
• The vehicle is not accelerating or decelerating more than a certain amount.
• The steering wheel is not being turned with a large force.
• The hands-off steering wheel warning (P.210) is not operating.
• The vehicle is being driven in the center of a lane.

Temporary cancelation of functions

• When the operating conditions are no longer met, a function may be temporarily canceled. However, when the operation conditions are met again, the operation of the function will automatically be restored. (P.209)
• If the operating conditions of a function are no longer met while the function is operating, a buzzer may sound to indicate that the function has been temporarily canceled.
• The steering assist operation of the function can be overridden by the steering wheel operation of the driver.

Lane departure warning function when the LTA is operating

• Even if the LDA warning method is changed to the vibration of the steering wheel, if the vehicle deviates from the lane while the LTA is operating, the warning buzzer will sound to alert the driver.
• If steering wheel operation equivalent to that necessary for a lane change is detected, the system will determine the vehicle is not deviating from the lane and the warning will not operate.

Hands off steering wheel warn-ing operation

• When the system determines the driver is not holding the steering wheel, a message urging the driver to grip the steering wheel and the icon shown in the illustration will be displayed on the multi-information display to warn the driver. If the system detects that the steering wheel is held, the warning will be canceled. When using the system, make sure to grip the steering wheel firmly, regardless of whether the warning is operating or not.

• If no operations are detected for a certain amount of time, the warning will operate and the function will be temporarily canceled. This warning may also operate if the driver only operates the steering wheel a small amount continuously.

Situations in which the hands off steering wheel warning may not operate properly

• Depending on the condition of the vehicle, handle control condition, and road surface, the warning function may not operate.

Enabling/disabling the system

• The LTA will change between ON/OFF each time the LTA switch is pressed.
• When the LTA is ON, the LTA indicators will illuminate.

WARNING

• Situations in which the functions may not operate properly

In the following situations, the functions may not operate properly and the vehicle may depart from its lane. Do not overly rely on these functions. The driver is solely responsible for paying attention to their surroundings and operating the steering wheel as necessary to ensure safety.

• When a preceding or surrounding vehicle changes lanes (Your vehicle may follow the preceding or surrounding vehicle and also change lanes)

• When a preceding or surrounding vehicle is swaying (Your vehicle may sway accordingly and depart from the lane)

• When a preceding or surrounding vehicle departs from a lane (Your vehicle may follow the preceding or surrounding vehicle and also depart from the lane)

• When a preceding or surrounding vehicle is being driven extremely close to the left/right lane line (Your vehicle may follow the preceding or surrounding vehicle accordingly and depart from the lane)

• When there are moving objects or structures in the surrounding area (Depending on the position of the moving object or structure relative to your vehicle, your vehicle may sway)

• When the vehicle is struck by a crosswind or the turbulence of other nearby vehicles

• Situations in which the sensors may not operate properly:

  •  P.196

• Situations in which the lane may not be detected: P.197

• When it is necessary to disable the system: P.192

Using the driving support systems

The operating state of the LTA system is indicated.

Emergency Driving Stop System

The emergency driving stop system is a system that automatically decelerates and stops the vehicle within its lane if the driver becomes unable to continue driving the vehicle, such as if they have suffered a medical emergency, etc.
During LTA (Lane Tracing Assist) control, if the system does not detect driving operations, such as if the driver is not holding the steering wheel, and determines the driver is not responsive, the vehicle will be decelerated and stopped within its current lane to help avoid a collision or reduce the impact of a collision.

WARNING
For safe use

• Driving safely is solely the responsibility of the driver. Pay careful attention to the surrounding conditions in order to ensure safe driving. The emergency driving stop system is designed to provide support in an emergency where it is difficult for the driver to continue driving, such as if they have had a medical emergency. It is not designed to support driving while drowsy or in poor physical health, or inattentive driving.
• Although the emergency driving stop system is designed to decelerate the vehicle within its lane to help avoid or help reduce the impact of a collision if the system determines that it is difficult for the driver to continue driving, its effectiveness may change according to various conditions. Therefore, it may not always be able to achieve the same level of performance. Also, if the operating conditions are not met, this function will not operate.
• After the emergency driving stop system operates, if driving becomes possible again, immediately begin driving again or, if necessary, park the vehicle on the shoulder of the road and set a warning reflector and flare to warn other drivers of your stopped vehicle.
• After this system operates, passengers should attend to the driver as necessary and take appropriate hazard prevention measures, such as moving to a place where safety can be ensured, such as the shoulder of the road or behind a guardrail.
• This system detects the condition of the driver through the operation of the steering wheel. This system may operate if the driver is aware but intentionally and continuously does not operate the vehicle. Also, the system may not operate if it cannot determine that the driver is not responsive, such as if they are leaning on the steering wheel.

Summary of the system
The operation of this system is separated into 4 control states. Through the control state “Warning Phase 1” and “Warning Phase 2”, the system determines if the driver is aware and responsive while outputting a warning and controlling the vehicle speed. If the system determines the driver is not responsive, it will operate in the control state “Deceleration stop phase” and “Stop hold phase” and decelerate and stop the vehicle. It will then operate continuously in the “Stop hold phase”.

Operating conditions
This system operates when all of the following conditions are met:

• When the LTA is on
• When the vehicle speed is approximately 30 mph (50 km/h) or more

Operation cancelation conditions
In the following situations, system operation will be canceled:

• When LTA control has been canceled (the LTA switch has been pressed, etc.)
• When the dynamic radar cruise control has been canceled
• When driver operations are detected (the steering wheel is held, the brake pedal, accelerator pedal, parking brake, hazard light switch, or turn signal lever is operated)
• When the driving assist switch is pressed while in the stop-and-hold phase
• When the engine switch has been turned from ON to off
• Situations in which some or all of the functions of the system can not operate: P.197

LTA control when the operation is canceled

• When emergency driving stop system operation is canceled, LTA control may also be canceled.

Warning phase 1
If driving operations are not detected after the hands-off steering wheel warning operates, a buzzer will sound intermittently and a message will be displayed to warn the driver, and the system will judge if the driver is responsive or not. If driving operations, such as holding the steering wheel, are not performed within a certain amount of time, the system will enter warning phase 2.

Warning phase 2

• After entering warning phase 2, a buzzer will sound in short intervals and a message will be displayed to warn the driver, and the vehicle will slowly decelerate. If driving operations, such as holding the steering wheel, are not performed within a certain amount of time, the system will determine that the driver is not responsive and enter the deceleration stop phase.
• The audio system will be muted until the driver becomes responsive.
• When the vehicle is decelerating, the brake lights may illuminate, depending on the road conditions, etc.

Deceleration stop phase
After entering the deceleration stop phase, a buzzer will sound continuously and a message will be displayed to warn the driver, and the vehicle will slowly decelerate and stop. After the vehicle stops, the system will enter the stop and hold phase.

Stop hold phase
After the vehicle is stopped, the parking brake will be applied automatically. After entering the stop and hold phase, the buzzer will continue sounding continuously and the emergency flashers (hazard lights) will flash to warn other drivers of the emergency.

Restricted functions after the operation is canceled
After shifting to the deceleration stop phase, the following functions will not be available until the engine is re-started even though the emergency driving stop system is canceled:
