FORWARD RECOGNITION CAMERA SYSTEM PRECAUTION


  1. PRECAUTIONS FOR SERVICING VEHICLE EQUIPPED WITH FORWARD RECOGNITION CAMERA


    1. When running the vehicle on a chassis dynamometer, cover the area in front of the forward recognition camera to prevent it from operating.

      Tech Tips


      • The forward recognition camera system captures the image ahead of the vehicle using the monocular camera and learns the direction of traffic while driving. When the actual driving situation is different from what is determined by the forward recognition camera, such as when running the vehicle on a chassis dynamometer, the forward recognition camera system may learn incorrect information.

      • When the forward recognition camera is covered, the message "Forward Camera System Unavailable" is displayed on the multi-information display. The message will disappear and the operation of the forward recognition camera system will return to normal after the cover is removed.
