\n<\/a><\/p>\n

Purpose<\/p>\n

\u2022 The lane-keep assist system provides steering assistance to help the driver stay within the vehicle lane if the vehicle might be deviating.<\/div>\n
\u2022 The forward sensing camera (FSC) detects the white lines (yellow lines) of the vehicle lane in which the vehicle is traveling and if the system determines that the vehicle may deviate from its lane, it operates the electric power steering to assist the driver\u2019s steering operation.<\/div>\n
\n
\n
Warning<\/div>\n<\/dd>\n
\n
\n
\u2022 The lane-keep assist system is not an automated driving system. In addition, the system is not designed to compensate for a driver\u2019s lack of caution, and over-reliance on the system could lead to an accident.<\/div>\n
\u2022 The functions of the lane-keep assist system have limitations. Always stay on course using the steering wheel and drive with care.<\/div>\n
\u2022 Do not use the lane-keep assist system under the following circumstances, otherwise it may result in an accident.<\/div>\n
\n
\n
\u2015 The vehicle is driven on slippery roads such as icy or snow-covered roads, and unpaved roads<\/div>\n
\u2015 Tires of a different specified size are used, such as a temporary spare tire<\/div>\n
\u2015 Tires with insufficient tread are used<\/div>\n
\u2015 The tire pressures are not adjusted to the specified pressure<\/div>\n
\u2015 The vehicle is being used to tow a camper or boat trailer<\/div>\n
\u2015 Tire chains are used<\/div>\n
\u2015 The vehicle is driven on roads with lane lines other than white (yellow) lines, such as an expressway<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
Caution<\/div>\n<\/dd>\n
\n
\n
\u2022 Heed the following cautions so that the lane-keep assist system can operate normally.<\/div>\n
\n
\n
\u2015 Do not modify the vehicle\u2019s suspensions<\/div>\n
\u2015 Always use wheels of the specified type and size for the front and rear wheels.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\n
\u2022 The lane-keep assist system may not operate normally under the following conditions.<\/div>\n
\n
\n
\u2015 The white (yellow) lane lines are less visible because of dirt or paint flaking<\/div>\n
\u2015 The white (yellow) lane lines are less visible because of bad weather (rain, fog, or snow)<\/div>\n
\u2015 The vehicle is driven on a temporary lane or section with a closed lane resulting from construction where there might be multiple white (yellow) lane lines, or they are interrupted<\/div>\n
\u2015 The camera picks up an obscure line, such as a temporary line being used for construction, or because of shade, unmelted snow, or grooves filled with water<\/div>\n
\u2015 The surrounding brightness suddenly changes such as when entering or exiting a tunnel<\/div>\n
\u2015 Back-light is reflected off the road surface<\/div>\n
\u2015 The road surface is wet and shiny after rain, or there are puddles on the road<\/div>\n
\u2015 The width of a lane is excessively narrow<\/div>\n
\u2015 The vehicle is driven on roads with tight curves<\/div>\n
\u2015 Heavy luggage is loaded in the luggage compartment or on the rear seat causing the vehicle to tilt<\/div>\n
\u2015 The vehicle is driven through a fork in the road or a junction<\/div>\n
\u2015 The shade of a guardrail parallel to a white (yellow) lane lines is cast on the road<\/div>\n
\u2015 The illumination of the headlights is weakened because of dirt or the optical axis is deviated at night<\/div>\n
\u2015 The road is excessively uneven<\/div>\n
\u2015 The vehicle is shaken after hitting a road bump<\/div>\n
\u2015 A vehicle in front of your vehicle is running near a white (yellow) lane line making it less visible<\/div>\n
\u2015 The windshield is dirty or foggy<\/div>\n
\u2015 Strong light is directed from the front of the vehicle (such as sunlight, or headlights (high-beam) of on-coming vehicles)<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/dd>\n<\/dl>\n

Functions<\/p>\n

\u2022 The body control module (BCM) and EPS control module performs the steering wheel operation assist and activates the lane-keep assist system based on the white lines (yellow lines) recognized by the forward sensing camera (FSC). For details on the forward sensing camera (FSC), refer to the [FORWARD SENSING CAMERA (FSC)]. (See FORWARD SENSING CAMERA (FSC) [(US)]<\/a>.)<\/div>\n
\u2022 With the lane-keep assist system, operation of the steering wheel operation assist can be turned on or off.For details on the personalization features, refer to the [PERSONALIZATION FEATURES]<\/div>\n

Steering wheel operation assist<\/p>\n

\n
\n
\u2022 When the vehicle approaches to white lines (yellow lines), the body control module (BCM) calculates the steering wheel angle required for the prevention of a lane departure and outputs a steering wheel angle request signal to the EPS CM.<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
\u2022 The EPS CM energizes the EPS motor to generate assist torque and supplement the insufficient steering angle for the prevention of a lane departure based on the steering wheel operation assist request signal.<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
\u2022 When the driver performs the prevention operation during steering wheel operation assist, the driver’s operation is given priority.<\/div>\n<\/dd>\n<\/dl>\n\n\n\n

\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 When the forward sensing camera (FSC) can detect either left or right white line (yellow line), the lane-keep assist system is performed. However, the steering wheel operation assist cannot be activated only when the vehicle deviates on the side where the white line (yellow line) is being detected.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
