2. ADVANCED PARKING GUIDANCE SYSTEM WHEN A THREE-DIMENSIONAL OBJECT IS NEARBY The guide on the screen targets a flatsurfaced object (road etc). When a three-dimensional object which juts out (an obstacle such as a truck bed) is nearby, observe the following precautions, being careful not to collide with the object. In the case shown above, the truck appears to be outside of the estimated path guide 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 estimated path guide lines. In reality if you back up as guided by the estimated path guide lines, the vehicle may hit the truck. Similarly, when the estimated path guide lines pass near any object(s) or obstacle(s), be sure to check the area behind and around the vehicle visually. ESTIMATED PATH GUIDANCE MODE The estimated path guide lines are displayed according to flat surfaces (such as the road). It is not possible to determine the position of three-dimensional objects (such as vehicles) using the estimated path guide lines. The width of the truck 370 PRIUS v (US) NAVI 47675U 11.09.08 12:54
