REAR VIEW MONITOR SYSTEM The width of the truck " 1 Approx. 1.5 ft. (0.5 m) The distance that appears on the screen between three−dimensional objects (such as vehicles) and flat surfaces (such as the road) and the actual distance differ as follows. In reality, A = B < C ( A and B are equally far away; C is farther than A and B ). However, on the screen, the situation appears to be B < C < A . On the screen, it appears that a truck is parking about 1.5 ft. (0.5 m) away. However, in reality if you back up to point B , you will hit the truck. Estimated course line display mode-The estimated course lines are displayed according to flat surfaces (such as the road). It is not possible to determine the position of the three−dimensional objects (such as vehicles) using the estimated course. In the case shown above, the truck appears to be outside of the lines and the vehicle does not look as if it will hit the truck. However, the width of the truck extends out from the truck in a line, and this line may actually be on the lines. In reality if you back up as guided by the lines, the vehicle may hit the truck. Similarly, when the lines pass near any object(s) or obstacle(s), be sure to check the area behind and around the vehicle visually. 243
