LDA (Lane Departure Alert) Warning buzzers LDA (Lane Departure Alert) Basic functions The LDA system warns the driver if the vehicle may deviate from the current lane or course*, and also can slightly operate the steering wheel to help avoid deviation from the lane or course*. The front camera is used to detect lane lines or a course*. *Boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc. Lane departure alert function When the system determines that the vehicle might depart from its lane or course*, a warning is displayed on a display, and either a warning buzzer will sound or the steering wheel will vibrate to alert the driver. Check the area around your vehicle and carefully operate the steering wheel to move the vehicle back to the center of the lane or course*. Vehicles with BSM: If the system determines that the vehicle may collide with a vehicle in an adjacent lane, the lane departure alert will operate even if the turn signals are operating. *Boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc. Lane departure prevention function If the system determines that the vehicle is likely to depart from its lane or course*, it provides assistance through steering wheel operations to help avoid deviation from the lane or course. 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, a warning message may be displayed and a warning buzzer may sound to alert the driver. Vehicles with BSM: If the system determines that the vehicle may collide with a vehicle in an adjacent lane, the lane departure prevention function will operate even if the turn signals are operating. *Boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc. Break suggestion function If the vehicle is swaying, a message will be displayed and a buzzer will sound to urge the driver to take a break. Warning: Before using the LDA system Do not overly rely on the LDA system. The LDA system is not a system which provides automated assistance in driving. However, as 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. Note: Operating conditions of each function Lane departure alert/prevention function This function is operable when all of the following conditions are met: The vehicle speed is approximately 30 mph (50 km/h) or more. Operation may be possible when the vehicle speed is approximately 25 mph (40 km/h) or more if vehicles, motorcycles, bicycles, or pedestrians are detected near the lane. The system recognizes a lane or course*. (When recognized on only one side, the system will operate only for the recognized side.) The lane width is approximately 9.8 ft. (3 m) or more. The turn signal lever is not being operated.(Vehicles with BSM: Except when a vehicle is detected in the direction that the turn signal lever is 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 sufficiently to perform a lane change. When the VSC or TRAC system is not turned off *Boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc. Temporary cancellation of functions When 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 each function) Operation of the lane departure alert function/lane departure prevention function Depending on the vehicle speed, road conditions, lane departure angle, etc., operation of the lane departure prevention function may not be felt or the function may not operate. Depending on the conditions, the warning buzzer may operate even if vibration is selected through a customize setting. If a course* is not clear or straight, the lane departure alert function or lane departure prevention function may not operate. The lane departure alert function or lane departure prevention function may not operate if the system judges that the vehicle is intentionally being steered to avoid a pedestrian or parked vehicle. Vehicles with BSM: It may not be possible for the system to judge if there is danger of a collision with a vehicle in an adjacent lane. The steering assist operation of the lane departure prevention function can be overridden by the steering wheel operation of the driver. *Boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc. When towing another vehicle TDA (Trailer Driving Assist)* When lift up When lift up Warning buzzers Hands off steering wheel warning (LDA) Hands off steering wheel warning operation In the following situations, a message urging the driver to operate the steering wheel and an icon will be displayed and a buzzer will sound to warn the driver. 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 that the driver is not securely holding the steering wheel, or the steering wheel is not being operated when the steering assist operation of the lane departure prevention function is operating Except for Puerto Rico, A.Samoa and New Caledonia: The length of time that the warning buzzer operates will become longer as the frequency of the steering assist operating increases. If the system judges that the steering wheel has been operated, the warning buzzer will stop. For Puerto Rico, A.Samoa and New Caledonia: The length of time that the warning buzzer operates will become longer as the frequency of the steering assist operating increases. Even if the system judges that the steering wheel has been operated, the warning buzzer will sound for a certain amount of time.

Changing LDA settings The LDA system can be enabled/disabled through a customize setting. (Customizable features) The settings of the LDA can be changed on the customize settings. (Customizable features) Warning: Situations in which the system may not operate properly In the following situations, the system 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 the boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc. is not clear or straight When the vehicle is struck by a crosswind or the turbulence of other nearby vehicles Situations in which the lane may not be detected: Situations in which the lane may not be detected Situations in which the sensors may not operate properly: Situations in which the sensors and the systems may not operate properly Situations in which some or all of the functions of the system cannot operate: Situations in which some or all of the functions of the system cannot operate When it is necessary to disable the system: When it is necessary to disable the system Multi-information display LDA (Lane Departure Alert) Displays and system operation The operating state of the lane departure alert function and steering assist operation of the lane departure prevention function are indicated.
