●When any part of the vehicle sags
When any part of the vehicle
sags due to the number of pas-
sengers or the distribution of
the load, there is a margin of
error between the fixed guide
lines on the screen and the
actual distance/course on the
road.
■When approaching thre e-dimensional objects
The distance guide lines are displayed according to flat surfac ed
objects (such as the road). It i s not possible to determine the posi-
tion of three-dimensional objects (such as vehicles) using the dis-
tance guide lines. When approaching a three-dimensional object
that extends outward (such as t he flatbed of a truck), be careful of
the following.
● Distance guidelines
Visually check the surroundings
and the area behind the vehi-
cle. On the screen, it appears
that a truck is parked at point
. However, in reality if you
back up to point , you will hit
the truck. On the screen, it
appears that is closest and is farthest away. However,
in reality, the distance to

farther than and .
