Traffic Jam Assist^{* *}If equipped Function Outline Traffic Jam Assist is a system which, through confirmation of the conditions by the driver, provides lane keeping, accelerating/decelerating, stopping, and starting off support on some highways and expressways. Also, in an emergency, the system can decelerate and stop, to help avoid a collision or help reduce the impact of a collision. Sensors that support the Traffic Jam Assist Sensors which detect the surrounding conditions (Sensors which detect the surrounding conditions) Sensors which detect the driver condition (Sensors which detect the driver condition) Note: 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 Changes in brake operation sound and pedal response Changes in brake operation sound and pedal response Situations in which the driver monitor may not operate properly Situations in which the driver monitor may not operate properly (if equipped) Emergency Driving Stop System Emergency Driving Stop System* Extended resume time of Dynamic radar cruise control Dynamic radar cruise control Traffic Jam Assist Function The Traffic Jam Assist function, through confirmation of the conditions by the driver, provides lane keeping, accelerating/decelerating and stopping support on some highways and expressways. This function is operable when all of the operation conditions are met. When this function is operating, it is possible to take your hands off of the steering wheel. (Operating conditions of the function) Before using the Traffic Jam Assist function, familiarize yourself with the content of the dynamic radar cruise control and the LTA (Lane Tracing Assist). Make sure that the driver steers the vehicle when entering a service area/parking area or toll gate, or when changing lanes. Driver monitor camera recording When the operation of Traffic Jam Assist is started, the following message will be displayed: “Allow Driver Monitor Camera Recording?” When recording is approved, the system records images of the area around the driver in certain crash or near crash-like situations, such as an SRS airbag being deployed or the vehicle hitting an object on the road. (Event data recorder) Warning: For safe use Driving safely is solely the responsibility of the driver. Do not overly rely on this system, and pay careful attention to the surrounding conditions in order to ensure safe driving. The Traffic Jam Assist function is not an automated driving system.This function provides the driver with information and driving assistance according to the road shape and conditions, traffic conditions, and the condition of the driver themself. Always pay careful attention to the surrounding conditions as use of the system is the responsibility of the driver. Depending on the condition of the surrounding area, the road, or the driver, the Traffic Jam Assist function may not operate or operation may be suspended. Also, it may not always be able to achieve the same level of performance. Read the operating conditions of the function carefully. Do not overly rely on this function and always drive carefully. As the recognition performance and control performance of the Traffic Jam Assist function are limited, driver operation is necessary to ensure safety while the system is operating. Also, the steering assist of this system is designed to operate only for slow steering operations during a traffic jam. While this function is operating, the lane deviation control function of the LDA will not operate. If, for some reason, the vehicle is about to deviate the lane, it is the driver’s responsibility to drive properly. Even if Traffic Jam Assist is operating properly, the surrounding conditions as recognized by the driver and detected by the system may differ. Therefore, it is necessary for the driver to pay attention, assess risks, and ensure safety. Over-reliance on this system to drive the vehicle safely may lead to an accident resulting in death or serious injury. While the Traffic Jam Assist function is operating, as driver operation may become necessary, the driver must ensure they have clear visibility of their surroundings. In certain situations, a message urging the driver to hold the steering wheel may be displayed by the Traffic Jam Assist function. In this case, hold the steering wheel and drive the vehicle manually to ensure safety. The Traffic Jam Assist function cannot detect the following objects. Operate the steering wheel, accelerator pedal, or brake pedal as necessary to avoid a collision. As the function will not be able to provide appropriate control, using it may lead to an accident resulting in death or serious injury. Objects on the road surface Vehicles outside of a lane (such as on the shoulder of the road) Potholes, cracks, ruts, or other road damage Road construction zones Vehicles running in parallel with your vehicle or nearby walls Animals Situations in which Traffic Jam Assist Function should not be used Do not use Traffic Jam Assist Function in situations such as the following. As the system will not be able to provide appropriate control, using it may lead to an accident resulting in death or serious injury. When it is necessary to disable the system When it is necessary to disable the system Situations in which the sensors may not operate properly Situations in which the sensors may not operate properly Situations in which the lane may not be detected Situations in which the lane may not be detected Situations in which the function may not operate properly In situations such as the following, the Traffic Jam Assist function may not operate properly. Manually operate the vehicle as necessary. When a sensor is splashed by water When the ambient temperature is high or low When a vehicle cuts in front of your vehicle When another lane merges into the lane in the same traveling direction as your vehicle When driving in low visibility condition When the vehicle posture is changing When the traction on the road surface differs greatly between the left and right side tires When driving on an expressway with no median strips or when driving on an expressway equipped with temporary median markers, such as poles. When there is a significant difference in speed between your vehicle and the other vehicle The map data has not been updated properly.

The dynamic radar cruise control and the lane tracing assist are operating. The turn signal lever is not being operated. The vehicle is not being driven around a sharp curve. The vehicle is being driven in the center of a lane. The driver monitor camera is detecting that the driver is facing front of the vehicle. The vehicle is driving in traffic jam on a highway or expressway at approximately 25 mph (40 km/h) or less. (In some situations, such as when a traffic jam starts, this function may be operational at approximately 20 mph [30 km/h] or less.) Safety Connect is being subscribed to. The driver’s door is closed. The driver’s seat belt is fastened. Customized setting of the Traffic Jam Assist is not set to off. Functions and components composing the system are in proper condition. Customized setting of the PCS (Pre-Collision System) is not set to off. Customized setting of the dynamic radar cruise control (re-start time extension) is not set to off. Temporary cancelation of the function 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. If the operating conditions of a function are no longer met while the function is operating, a buzzer may sound with a display to indicate that the function has been temporarily canceled. If no driver’s responses to the indication are detected, the driver emergency stop assist function may operate. For types of display and action to be taken, see the page mentioned below. (Displays and system operation) Driving operations during controlled driving Accelerator pedal As with normal driving, acceleration can be performed by depressing the accelerator pedal.In some situations, such as when driving at approximately 6 mph (10 km/h) or more and the accelerator pedal is depressed, this function will be canceled. Brake pedal As with normal driving, deceleration can be performed by depressing the brake pedal. However, controlled driving will be cancelled. Steering wheel As with normal driving, the steering wheel can be operated. If the steering wheel is operated more than a certain amount, controlled driving will be cancelled.
