OperationWarning buzzers
LTA (Lane Tracing Assist)LTA functionsWhen driving on a road with clear lane lines with the dynamic radar cruise control
operating, lane lines and preceding 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 the 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 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 systemDo not overly rely on the LTA system. The LTA system is not a system which provides
automated assistance in driving and it is not a system which 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.Note:Operating conditions of functionThis 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 (Hands off steering wheel warning operation) is not operating.The vehicle is being driven in the center of a lane.Temporary cancelation of functionsWhen the operating conditions are no longer met, a function may be temporarily canceled.
However, when the operation conditions are met again, operation of the function will
automatically be restored. (Operating conditions of function)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 operatingEven if the LDA warning method is changed to 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 operationIn 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 operatingIf 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 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.LTA (Lane Tracing Assist) switchSwitches
LTA (Lane Tracing Assist) switchEnabling/disabling the systemThe 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 functions may not operate properlyIn 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 vehiclesSituations in which the sensors may not operate properly: Situations in which the sensors may not operate properlySituations in which the lane may not be detected: Situations in which the lane may not be detectedWhen it is necessary to disable the system: When it is necessary to disable the systemOperation display of steering wheel operation supportThe operating state of the LTA system is indicated.
