ROAD SIGN ASSIST SYSTEM


  1. OUTLINE


    1. The Road Sign Assist (RSA) system has been adopted. The system recognizes traffic signs using the forward recognition camera and provides information to the driver via the multi-information display.

    2. The RSA system can recognize various traffic signs* of different countries. By informing the driver of the speed limit as it changes while driving within or across borders, it makes it easier for the driver to be aware of different speed limits, assisting safe driving.

      Tech Tips

      *: Signs that comply with the Vienna Convention on Road Signs and Signals (including electronic signs and blinking signs)

    3. On vehicles equipped with a navigation system, the RSA system performance has been enhanced by utilizing the map information of the navigation system.

  2. PRECAUTION


    1. General Handling Precautions


      1. RSA is a system which supports the driver by providing information from traffic signs to the driver. The RSA system does not serve as a replacement for a driver's vision or awareness. It is necessary for the driver to always pay attention to the traffic conditions and applicable rules while driving.

      2. The RSA system may not detect or correctly recognize speed limit signs if they are dirty, bent or blocked by an object. It is necessary for the driver to confirm all speed limit signs while driving.

      3. When the unit of speed being used or the direction of traffic changes, it may take some time for the system to learn of the changes. Until the learning is complete, the system may not detect the correct unit of speed or the direction of traffic and may subsequently display incorrect information. It is necessary for the driver to always pay attention to the traffic conditions and applicable rules while driving.

      4. The system may not detect traffic signs under the following conditions:

        B004GZTE01
        Number Condition
        *a The orientation of the forward recognition camera is deviate.
        *b The vehicle passes the sign too quickly after the sign comes into view.
        *c Dirt, snow, ice or a sticker is on the windshield glass in front of the forward recognition camera.
        *d During bad weather (such as heavy rain, heavy snow or dense fog).
        *e The headlights of an oncoming vehicle or sunlight is shining directly on the forward recognition camera.
        *f The sign is dirty, faded or tilted, or the contrast of an electronic sign is poor.
        *g Whole or part of the sign is blocked by an object such as a pole, tree or a tall track passing the sign.

      5. The system may incorrectly recognize traffic signs under the following conditions:

        B004H95E02
        Number Condition
        *a A sticker or graphic is on the rear of a preceding vehicle.
        *b A sign is on an adjacent lane or side road, or immediately after traffic lanes merge or diverge.
        *c An object which is not a traffic sign is similar in appearance.
        *d The system has not completed learning after entering a different country.*

        *: When the unit of speed or the direction of traffic changes, the system may not display the correct speed or overtaking lane.

    2. Precautions for Forward Recognition Camera


      1. Keep the windshield glass clean. If dirt, snow or ice is on the windshield glass, the forward recognition camera may not operate correctly.

      2. Do not apply a sticker, etc. to the area of the windshield glass around the forward recognition camera.

      3. Do not splash liquid on the forward recognition camera.

      4. Do not flash a strong light source, such as an LED flashlight, on the forward recognition camera.

      5. Do not apply film to the windshield glass.

      6. Do not install an antenna in front of the forward recognition camera.

      7. If the windshield glass fogs up, turn on the defogger to clear condensation. The windshield glass easily fogs up when the heater is set to foot mode and this may affect the performance of the forward recognition camera.

      8. Do not damage the monocular camera lens or allow it become dirty. When cleaning the inner surface of the windshield glass, do not allow cleaning agent to contact the camera lens. Do not touch the camera lens.

      9. The orientation of the forward recognition camera is precisely adjusted. Do not remove, or change the position or orientation of the forward recognition camera.

      10. Do not subject the forward recognition camera to a strong impact, and do not disassemble it.

      11. Only replace the windshield glass with a genuine part.

      12. Do not place reflective items on the dashboard.
