    2. Checking Traveling Direction and Avoiding Obstacles

      1. In order to avoid obstacles while traveling forward, the driver should steer in such a way that the wheel path does not overlap with any obstacles. By doing so, obstacles can be avoided and passed.

        A00XL1Q

        Tech Tips

        • As it is difficult to understand the height differences of obstacles using the images received from the cameras, care should be taken of large differences in height.

        • As it is difficult to perceive distances using the images of the wide view front camera assembly, distances to items displayed should be confirmed directly.
