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 vvehicle’slane 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 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 via a display 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 auto-mated 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 (except when the preceding vehicle is small, such as a motorcycle).
• 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.167) 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.166)
• 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 warning operation
In the following situations, 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.

• When the system determines the driver is not holding the steering wheel while the function is operating no operations are detected for a certain amount of time, a buzzer will sound, 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 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 enabled/disabled each time the LTA switch is pressed. When the LTA is enabled, the LTA indicator will illuminate.

WARNING

• Situations in which the function may does not operate pproperlyIn 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 departs from a lane (Your vehicle may follow the preceding or surrounding vehicle and also depart from the lane)
• When a preceding or surrounding is being driven extremely close to the left/right lane line (Your vehicle may ffollowthe the preceding or surrounding 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
