Lane-keep Assist System (LAS)

The LAS provides steering assistance to help the driver stay within the vehicle lane if the vehicle might be deviating.

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’s steering operation. The system also alerts the driver by displaying an alert on the multi-information display and the active driving display. Use the system when you drive the vehicle on roads with white (yellow) lines such as expressways and highways.

Do not rely completely on the LAS:

  • The LAS is not an automated driving system. In addition, the system is not designed to compensate for a driver’s lack of caution, and over-reliance on the system could lead to an accident.

  • The functions of the LAS have limitations. Always stay on course using the steering wheel and drive with care.

  • Do not use the LAS under the following circumstances, otherwise it may result in an accident.

    • The vehicle is driven on slippery roads such as icy or snow-covered roads, and unpaved roads.

    • Tires of a different specified size are used, such as a temporary spare tire.

    • Tires with insufficient tread are used.

    • The tire pressures are not adjusted to the specified pressure.

    • The vehicle is being used to tow a camper or boat trailer.

    • Tire chains are used.

    • The vehicle is driven on roads with lane lines other than white (yellow) lines, such as an expressway.

The system may not operate normally under the following conditions.

  • The white (yellow) lane lines are less visible because of dirt or paint flaking.

  • White (yellow) lane lines are less visible because of bad weather (rain, fog, or snow).

  • 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.

  • 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.

  • The surrounding brightness suddenly changes such as when entering or exiting a tunnel.

  • Back-light is reflected off the road surface.

  • The road surface is wet and shiny after rain, or there are puddles on the road.

  • The width of a lane is excessively narrow.

  • The vehicle is driven on roads with tight curves.

  • Heavy luggage is loaded in the luggage compartment or on the rear seat causing the vehicle to tilt.

  • The vehicle is driven through a fork in the road or a junction.

  • The shade of a guardrail parallel to a white (yellow) lane line is cast on the road.

  • The illumination of the headlights is weakened because of dirt or the optical axis is deviated at night.

  • The road is excessively uneven.

  • The vehicle is shaken after hitting a road bump.

  • A vehicle in front of your vehicle is running near a white (yellow) lane line making it less visible.

  • The windshield is dirty or foggy.

  • Strong light is directed from the front of the vehicle (such as sunlight, or headlights (high-beam) of on-coming vehicles).
