When any part of the vehicle sags
When any part of the vehicle
sags due to the number of
passengers or the distribu-
tion of the load, there is a
margin of error between the
fixed guide lines on the
screen and the actual dis-
tance/course on the road.
■
When approaching three-dimensional objects
The distance guide lines are displayed according to flat surfaced
objects (such as the road). It is not possible to determine the posi-
tion of three-dimensional objects (such as vehicles) using the vehi-
cle width guide 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.
●
Vehicle width guide lines
Visually check the surround-
ings and the area behind the
vehicle. In the case shown
below, the truck appears to
be outside of the vehicle
width guide lines and the
vehicle does not look as if it
hits the truck. However, the
rear body of the truck may
actually cross over the vehi-
cle width guide lines. In real-
ity if you back up as guided
by the vehicle width guide
lines, the vehicle may hit the
truck.
