When any part of the vehicle sags
●
When any part of the vehicle sags
due to the number of passengers
or the distribution of the load,
there is a margin of error between
the guide lines on the screen and
the actual distance/course on the
road.
When approaching three-dimensional objects
■
The estimated course lines target a flat surfaced objects (such as the road). It
is not possible to determine the position of three-dimensional object (such as
vehicles) using the estimated course lines and distance guide lines. When
approaching a three-dimensional object that extends outward (such as the
flatbed of a truck), be careful of the following.
Estimated course lines
●
Visually check the surroundings
and the area behind the vehicle.
In the case shown in the illustra-
tion, the truck appears to be out-
side of the estimated course lines
and the vehicle does not look as if
it will hits the truck. However, the
rear body of the truck may actu-
ally cross over the estimated
course lines. In reality if you back
up as guided by the estimated
course lines, the vehicle may hit
the truck.
